PIPE CONSERVATION OZONE AGAINST MILLION ACCUMULATION OF THE MYTILOIDA AND VENEROIDA ORDERS "

APPLICATION FIELD

The "MODULAR OZONE GENERATION AND TRANSFER SYSTEM FOR PIPE CONSERVATION AGAINST MILLION ACCUMULATION OF MYTILOIDA AND VENEROIDA ORDERS" belongs to the disinfection sector of pipelines of the mytiloid and veneroida, such as the golden and zebra mussels, and their larvae in the turbine cooling system of the hydroelectric plants and in the catchment pipes of rivers and reservoirs.

TECHNICAL STATE

In order to sail safely, transoceanic vessels always need to keep the vessel's weight constant and this is done using the ballast tank. When they dock at ports, unload or load goods, ships change weight, making it necessary to fill or empty the ballast tank with local water, the result being a "water exchange" between various ports around the world. Along with water are carried numerous species from different ecosystems, new ecosystems are not always prepared to defend themselves from new species, and can cause serious environmental impacts.

The golden mussel is a small bivalve mollusk from China, which arrived in South America in the ballast waters of merchant ships, invaded the Paraná-Paraguay basin and endangers the multiple uses of water resources. Owing to its ability to survive in both fresh and brackish water, its invasion was successful, the larvae fixed themselves on the boat's hulls and when sailing along the rivers they reproduced uninterruptedly, thus spreading the mussel throughout the country. -2 / 15-. ^ DaV / \

This little mollusk clings to any hard substrate.

gregarious habit and reproduces quickly. The absence of predators and parasites that control their population causes it to spread through the Brazilian watersheds. In 1991 it was found at the mouth of the River Plate, and today it is present in the Pantanal and advances through the Brazilian hydroelectric plants in the Paraná River basin.

In hydroelectric plants, the accumulation of mussels can sink floating equipment, disrupt the operation of submerged equipment and clog pipelines, causing turbine cooling systems to become clogged and interrupt power generation.

In the environment, the mussel takes up all the space available to it,

and may change the composition of invertebrate species in the aquatic environment and, with changes in the food chain, the capture of certain fish species may be impaired.

For water users, the mussel can cause a number of problems:

invasion of water supply, storm drainage and catchment pipes for irrigated agriculture;

• obstruction of cooling systems of industries and hydroelectric plants;

• loss of floating structures intended for overweight leisure;

• impairment of the operation of boat engines;

• loss of net tanks.

Similar problems occur in the United States and Canada, countries in which zebra mussel has spread. "(Accessed 23/09/2009 - http://www.furnas.com.br/mioambiente mexilhao2.asp) -3 / 15- at *% r> / I Ai

The identification of the Ivarval forms of Limnoperna fortunei is ^ nRab: J ^ l

basic and indispensable step for the development of studies on the density? and growth of the golden mussel. It is also known that it is in the Ivalval phase that the species disperses, invading new environments, especially in areas where the water has good oxygenation, as in the water collection systems of treatment plants, pipes, suction pumps, irrigation systems, industrial refrigeration and heat exchanger of hydroelectric units (MANSUR, MCD; CP DOS SANTOS; G. DARRIGRAN; I. HEYDRICH; CT CALLIL & FR CARDOSO. 2003. "First qualitative and quantitative data of the golden mussel, Limnoperna fortunei (Dunker , 1857), in the Jacuí Delta, Guaíba Lake and Laguna do Patos, Rio Grande do Sul, Brazil and some aspects of its invasion in the new environment. "Revista Brasileira de Zoologia, Curitiba, 20 (1): 75-84 ; DARRIGRAN, G. & G. PASTORINO. 1995. A recent introduction of a freshwater Asiatic bivalve Limnoperna fortunei (Mytiidae) into South America ". The Veliger, Berkeley, 32 (2): 171-175).

The earliest data on L. fortunei's Ivarval phases (Dunker, 1857) is found in the works of CHOI & SHIN (CHOI, SS & JS KIM. 1985. Studies on the metamorphosis and growth of larva in Limnoperna fortunei. , Seoul, 1: 13-18.) And CHOI & KIM (CHOI, SS & CN SHIN. 1985. Study on Early Development and Variety of Limnoperna fortunei. Korean Journal of Limnology, Seoul, 1: 5-12), correspondents to populations originating in Korea. CHOI & SHIN described the species as gonocoristic (dioecious), whose development would be through a larva very similar to that of other marine bivalve species, as follows: after egg fertilization, the embryo would go through various stages of blastomer segmentation and in three hours and thirty minutes it would reach the stage of hair removal; after another five to six hours it would become the larva surrounded by a straight hinged shell (called larva D); after approximately five days, this would become veliger characterized by the presence of the veil or "velum" that allows an intense swimming activity and consumption of many nutrients; The last stage would comprise a well-developed juvenile larva with a well-developed foot, ready to settle and attach to the substrate.

complemented the work of other authors by offering measurements of

Larval and in particular of larva D, separating into three types: Larva "D" early stage & ^ g „^ vtfb

(Iarval shell length - 140 μιτι), intermediate D-phase larva (167 μηη) and

final D-phase larva (210 μηη).

To solve the problem, they chose to measure the larvae and redescribe them, observing morphological characteristics and their behavior, which allowed them to determine the stage of development of each phase. They considered length and height to be essential for redefining each Iarval phase by measuring shell size when present.

They observed greater anatomical and morphometric similarity of the larvae of L. fortunei with those of Dreissena spp. (D. polymorpha, D. rosteriformis bugensis) from Eastern Europe than with C. fluminea larvae from Southeast Asia. It is interesting to note that L fortunei belongs to the order Mytiloida, which is distinct from the Veneroid order of which Dreissena and Corbicula are part. It should also be clarified that D. polymorpha popularly known as "zebra mussel" is an invasive bivalve, found in the hemisphere.

This same author also draws attention to the fact that L fortunei has filamentous gills joined only by ciliary junctions, which would not allow them to support eggs, embryos or marsupial incubation.

According to KOWALSKY & KOWALSKY (KOWALSKY, EL & KOWALSKY, SC 2008. "Review of methods for controlling golden mussel in pipes", www.producaoonline.ufsc.br Online Production Magazine, ISSN 1676-1901, Vol. 8, N0 2, July 2008) The control of the golden mussel is very complex, and the degree of complexity is intensified as the application of control methodologies is delayed. So far there is no control method for this macrofouling that can be considered as definitive. Attempts to control have so far been halted by physical methods, chemicals, antifouling paints, biological control by predators, parasites and competitors. Based on this publication, the state of the art regarding the physical methods of mussel control is presented.

The most efficient chemical methods to date can present damage to the environment due to the waste produced during and after the treatment process, failing to comply with Federal Law No. 9,433 / 1997 and State Laws. Antifouling paint has only been shown to be effective in certain cases, and is often prohibitive because pipe replacement is infeasible in industrial plants already in operation. Biological control may lead the environment to support new unnatural habitat species.

Physical methods are a viable and inexpensive alternative currently used. Generally, in electrical methods it is used

immersed in water where an electric potential difference is applied, corrMÇfyg - objective to generate an electric field in the middle between them. Early work has shown that the use of direct current electric field (DC) is not efficient to cause mortality in "Dreissena" larvae. This is due to the fact that the larvae have an outer layer with insulating properties and thus the direct current tends to circulate around it and not through it. To circulate a fatal direct current through the larva would require a high electric field which would require a high consumption of electricity, making the method economically unviable.

of short duration. Electric field pulses lasting from micro seconds to nano seconds can be generated with power in the order of megawatts. This applied instantaneous power produces rapid variations in the electric field and, as a consequence, induces electrical current inside the larva causing mortality or stunning, which prevents the larva from sticking to the pipe walls.

control. Field and laboratory studies indicate that magnetic water treatment causes degeneration of tissue associated with the respiratory tract, and other specific structures linked to gas exchange and feeding. In closed systems, mussels exposed to treatment with low frequency electromagnetic fields indicate 100% mortality, mainly attributed to the loss of calcium by the mollusk. The results obtained in researched works are quite inconclusive regarding the method, but indicate that the method appears to be effective in the long term. This water treatment system is currently being applied to ships and is already patented in the United States of America (US 5540835 "Growth regulation of zebra mussels through magnetic water treatmenf").

The most promising technique is that which uses electric field pulses.

The magnetic method can become a potential method of

30

The acoustic method basically is divided into three main lines: Cavitation, Sound Treatment and Vibration. Studies by Ontario Hydro £ '\ hT

referring to the continuous use of cavitation in the frequency range ^

380 kHz show that the process kills the clam. Vibration has been applied to prevent adult and juvenile mussels from attaching themselves to structures, and currently there are commercial equipment working at frequencies of 28 Hz1 used on vessels and also on hydroelectric plants. Laboratory experiments have shown that the correct use of low frequency sound prevents mussels from settling in structures, reduces mobility and affects their reproduction.

The UV radiation method is based on the fact that it is lethal to various species of aquatic organisms, especially those in planktonic form. To prevent them from being influenced by radiation, they may change depth or position in water, which is not possible in piping systems. Exposure to UV radiation has reduced the settlement of barnacles and other larvae in transparent tubes where salt water circulates, and it is believed that in freshwater cases the efficiency is higher as there are fewer minerals. that absorb UV radiation. U.S. Patent No. 5,655,483 - "Method and apparatus for controlling zebra and related mussels using ultraviolet radiators" deals with this technology.

The total lack of oxygen (anoxia) is deadly to animals living in an aquatic environment and an insufficient amount of oxygen (hypoxia) can weaken the strengths of individuals, making them easy prey for various diseases and impairing their ability to reproduce. also in a method that can be applied. Anoxia has been caused by the constant gasification of water with N2, and the published studies show that the low temperatures of anoxia do not have the expected effects, producing extremely low mortality rates, which could even be considered as within the normal range. natural standard deviations. However, mortality rates at temperatures above 150 ° C increase with increasing temperatures. Another parameter that influences the control method is the size of the mollusk, with small molluscs requiring more oxygen than larger mollusks, which makes treatment more efficient for smaller mollusks. Another fact observed is that 'ajaX molluscs from Pr -8 / 15- Λ%

die faster in places contaminated with dead mollusks, # | is ^

There is a competition for oxygen between the bacteria that decompose dead molluscs and the live molluscs. An important detail is that the treatment exposure time is extremely high, ranging from 5 to 800 h on average.

Treatment by anoxia or hypoxia as a non-chemical and therefore environmentally friendly method can be used as an efficient method in closed and standing water piping systems such as ballast water but due to reduced levels. Oxygen from water also decreases in pH, inducing pipeline oxidation, which may be circumvented by using nitrogen to cause water deoxygenation.

The chemical methods are based on the following products: copper sulfate (CuSO4), chlorine dioxide (from the reaction of sodium chlorite with hydrochloric acid or sulfuric acid with sodium chlorate solution and hydrogen peroxide) and ozone (O3).

Copper sulphate (CuS04) has insecticidal, algicidal, fungicidal and

herbicide. Its use is also common for the destruction of fungi and insect larvae in plantations. CuS04 is highly soluble, but under certain conditions of higher water hardness and alkalinity, it is rapidly precipitated as insoluble compounds that deposit in the sediment of the body of water. For these reasons, the effective dosage in nature can reach values so much higher than those obtained in laboratory tests. The use of this substance as a mollusc has not been recommended by the EPA due to its high toxicity to fish and aquatic vertebrates.

Chlorine dioxide has been used to control golden mussel, however few studies report the damage caused by the degradation products of this compound. According to Soares, MF et al (Soares, MF et al, "Development and adaptation of environmental technologies for population control of golden mussel (Limnoperna fortunei)", CNPq Report Process: 48337 / 2004-7) due to their highly oxidizing characteristics and solubility in water, chlorine dioxide tends to turn into some other substances, which are undesirable in the environment by their

toxicity. For example, chlorite, chlorate and bromate are formed. About 50% to 70% of the chlorine dioxide consumed is reduced to chlorite and 30% X-1 'of chlorine dioxide is also derived from chlorate and chloride. chlorine dioxide degradation products. In insignificant amounts further haloacetic acids, halo ketones and haloaldehydes may be formed.

In waters treated with chlorine dioxide bromates may occur as a result of oxidation of bromides by sunlight over a wide range of pH values. Unlike ozone, chlorine dioxide does not transform bromide ion into bromate as long as photolysis is prevented (some bromate may form under the influence of sunlight).

Chlorites have a toxic action that occurs mainly in the form of oxidative damage in red blood cells. Data on chlorite genotocicity are contradictory, in chronic exposure studies chlorite did not produce an increase in tumors in laboratory animals. Chlorate toxicity is similar to chlorite, but oxidation of this compound causes less damage.

The formation of trihalomethanes was verified from chlorine and chlorine dioxide treated aquatic humic substances. In the evaluation of the influence of chlorine and chlorine dioxide on the formation of byproducts, which are generated after oxidation of aquatic organic matter, the result suggested that operational care should be taken in water supply systems when it is distributed to the population. due to chloroform formation. After 24 hours of reaction the formation of chloroform occurred in samples with chlorine dioxide, about 60 times smaller when compared with samples with chlorine. Chlorine dioxide was also more efficient in terms of the oxidation power of organic matter and especially in reducing chloroform formation when compared to chlorine.

Chlorine dioxide has a high oxidizing disinfection power, being able to control in addition to algae and microorganisms, also ammonia nitrogen, iron, manganese and phenol, among other contaminants. It also weighs in his favor that he acts stably regardless of pH,> - <FIs.

reducing the consumption of inputs for correction. And this added to the important feature: It does not react with water, such as chlorine or hypochlorite remaining as a dissolved gas. Already the other two disinfectants form hypochlorous acid (HCIO), which despite being the disinfecting agent can be dissociated into hypochlorite ion (non-disinfectant) and still react with organic compounds, ammonia and phenol, forming undesirable by-products, such as organochlorines in general. , chlorophenols, trihalomethanes or chloroamines, and also generate bad odor and color variation.

The state of the art considers the use of ozone as a disinfectant, being inserted into the turbine cooling piping and avoiding the accumulation and development of mussel larvae in the pipeline.

Ozone (O3) is an allotropic variety of the oxygen element (O), formed by three atoms of this element, joined by single and double bonds, being a resonance hybrid with an average bond length of 0.128 nm, unstable gas at room temperature. Highly reactive and oxidizing, diamagnetic, it liquefies at a temperature of -112 ° C and has a freezing point at - 251.4 ° C, has a pale blue color, reaching a dark blue color when transitioning to liquid state. Its half-life when dissolved in water is 1.25 minutes at 26 ° C (depends on the concentration of ozone and other substances contained in water) and at 20 ° C, 20 minutes.

Basically, what differentiates ozone from the various disinfectants is its mechanism of destruction of microorganisms. Chlorine, for example, acts by diffusion through the cell wall, then acting on vital elements within the cell, such as enzymes, proteins, DNA and RNA. Because it is more oxidizing, ozone acts directly on the cell wall, causing it to rupture, requiring less contact time and making it impossible to reactivate. Depending on the type of microorganism, ozone can be up to 3,125 times faster than chlorine in cell inactivation.

Studies (Claudi, R. & Mackie, GL, "Practical Manual for Zebra Muscle Monitoring and Control." Boca Raton, Lewis Publishers, 1994) show that for 100% mortality, a concentration of 0.5 mg / l needs a -11 / 15- V0 ^ daV • 7 Ma - ι fo

Companies such as Ontario Power Generation and Duvivier of Europe have been performing water treatment through the method, which is recommended for hydroelectric power plant cooling systems (OZONE AS A CONTROL METHOD. Http://www.wes.armv.mil/el/ zebra / zmis / zmishelp / Access on Feb. 19, 2003, Turner1 SK, Zebra mussels, Albany New York 1990.

Published studies show ozone as a potential control method that produces the same results as the water chlorination process but is less environmentally friendly (Wanwick Fisher, S.; Bernard, DO). Iaboratory and field studies Journal of Shellfish Research, Vol. 10, No. 2,367-371. 1991)

Ozone is produced from the oxygen present in atmospheric air. Oxygen concentrating equipment is responsible for capturing ambient air and separating oxygen molecules, causing oxygen, which is 21% in the atmosphere, to be concentrated above 90%. High oxygen concentration is essential for ozone production, increasing the efficiency of ozone generators.

After concentrate, oxygen passes through a 3-way solenoid valve.

routes before entering the ozone generators. This valve has the function of protecting the oxygen concentrator, preventing residual ozone return to the device and preventing back pressure to occur in the 'lung' that generates the initial flow.

Once concentrated, oxygen passes through the ozone generator where the

molecules are broken and oxygen free atoms join another oxygen molecule, forming ozone. Its industrial production can be through the passing of a high voltage electric arc through a stream of oxygen or dry air, and its self-decomposition occurs even at ambient temperatures, being accelerated by high temperatures or by contact with catalysts.

DETAILED DESCRIPTION

The "MODULAR OZONE GENERATION AND TRANSFER SYSTEM FOR PIPER CONSERVATION AGAINST MILLION ACCUMULATION OF MYTILOIDA AND VENEROIDE ORDERS" is based on the use of ozone as a disinfecting agent in the pipeline where larvae settle and larvae and development to the mussel stage, causing the larvae not to settle and to produce fouling, and consists of one or more modules composed of an oxygen concentrator system (1) capable of capturing ambient air and concentrating oxygen at percentages greater than 90%, a minimum of four 3-way solenoid valves (2) for air flow of at least 10 L / min for safety and automation, made of ozone-resistant material, one or more ozone-generating systems (3). ) capable of generating a minimum of 20 g / h, one or more specially ozone-adapted pressurizing vacuum pumps (4) capable of working with air flow rates of at least 10 L / min and capable of generating pressures up to 10 bar, and two or more nozzles (5) made of material also resistant to ozone degradation. The ozone generation and transfer device works in modules, the amount of which is determined as a function of water flow, pipe diameter and individually prior to installation as a whole. intensity of the problem, requiring each case to be the

The process considers the application of gaseous ozone in the form of

bubbles in the water a few feet away from the critical points of mussel accumulation, in parallel with the water flow, thus reducing their instant dissolution. Ozone in the form of small bubbles persists in the environment longer, keeping it unsuitable for larvae installation and the consequent development of mussels. When ozone dissolves in water, it reacts directly with the organic charge and any other substances present.

specially adapted for ozone that increases flow pressure by allowing ozone to be inserted into pressurized pipelines, ie capable of working with air flow rates of at least 10 L / min and generating pressures up to 10 bar. It is recommended for system protection to use 2 pumps per injection point, preventing the pumps from running continuously and overheating, which can shorten ozone half-life and consequently lower the injected ozone concentration. . Pump switching is performed automatically through electronic components which, in addition to turning the pumps on / off, also actuate solenoid valves installed before the pumps ensuring complete ozone flow redirection.

inserted in the contaminated piping, but the insertion must be done efficiently, and for this, nozzles are used that are positioned inside the piping in parallel direction and even direction of flow. These nozzles are devices such as an inverted pitot tube that inject ozone gas in parallel with the flow of water, optimizing its stay in gas form. To optimize ozone gas input, at least 2 nozzles are installed per application point, in this case positioned symmetrically distributed on the same circumference of the pipe. Other positions at equitable distances in

To insert ozone one or more vacuum pumps are used.

After passing through the pumps, the pressurized ozone is capable of being T '"* -. A„ _ g.

270 °, etc. The number of nozzles is determined as a function of pipe diameter and flow.

For ozone generation it is recommended to use a room

where oxygen concentrating equipment, ozone generators and pressurizing pumps are housed. This room should be constantly monitored for ozone in the ambient air, thus ensuring operator safety against any leakage-related incidents. The room must also have an exhaust system, which is responsible for removing hot and low oxygen air, thus ensuring a climate-controlled room with oxygen-fueled air and the ideal temperature.

For the installation of the "MODULAR OZONE GENERATION AND TRANSFER SYSTEM FOR PIPE CONSERVATION AGAINST MYCYLOID AND VENEROIDE ORDERS", it is recommended that the ambient temperature should be between - 50 ° C and 40 ° C and The pipeline where the ozone gas will be inserted must have pressures between -0.10 and 3.50 bar, with no restrictions on the flow of the pipeline, since the system operates in modules and is capable of adapting to any flow.
