There is a problem regarding contamination of the water-containing system with various pollutants such as algae, fungi, bacteria, surfactants, various organic compounds, and the like. The pollutant is
As a result, the production of goods can be reduced and the water system can become so contaminated that it requires extensive cleaning.

Various known compositions that can be used to reduce the concentration of the contaminants from the water-containing system, preferably to remove or decompose the contaminants, often utilize chlorine. However, the use of such chlorine-containing compositions involves a variety of environmental and safety hazards, and further, the processing of products made using chlorine-containing compositions is not The above monitoring and regulation is required. In addition, chlorine-containing compositions are frequently used in gaseous form where sufficient safety and training methods are required for use.

The following examples further illustrate the invention, but are not to be construed as limiting the scope of the invention more than necessary.

Example 1
This example illustrates the preparation of the composition of the present invention.

31.23 L (8.25 gallons) of a 35 wt% hydrogen peroxide solution (obtained from FMC Corporation (Philadelphia, PA) as an industrial brand of 35 wt% aqueous hydrogen peroxide) 34.675 gallons)
Of low solid water (PGT ink (Ced
from Ar Hill, Texas). Low solid water was produced by reverse osmosis. ) And room temperature (about 21.11 ° C. (70 degrees Fahrenheit)) and atmospheric pressure, after which the resulting product was prepared to prepare 208.2 L (55 gallons) of the composition of the present invention. The total mixing time was about 15 minutes. The resulting mixture is then 3.12

Low solid water was produced by reverse osmosis).
2 L (11.55 gallons) of 5% by weight glycolic acid solution and room temperature (about 21.1
Contact at 1 ° C. (70 ° F.) and atmospheric pressure, resulting in about 208.2 L (5
5 gallons) of the inventive composition was obtained. Hereinafter, this is referred to as “Composition A” and the pH was about 3.3.

Example 2

The equipment was purchased from Packaging Corporation of America (PCA: Waco, Texas) and has been in use for several years. Significant amount of sticky residue (
The color of the residue is determined by prolonged drying until a translucent appearance of the sticky product is obtained.
It was a dirty white. ) Was observed. A significant concentration of tacky residue is found in the adhesive applicator cross-member (approx. 10 inches below the paste applicator, which applies the paste to the paperboard being rolled up to form a cardboard box sheet ( cross-
member). Glue residue levels were accumulated to such a degree as to cause manufacturing problems. PCA requested several chemical companies for assistance in developing products that facilitate the removal or removal of sticky residues. Twenty unsuccessful attempts were made by the chemical sales company that performed it. after that,
Composition A was applied directly to the sticky residue using a trigger sprayer. Within about 5 minutes, the translucent appearance of the sticky residue is white, which is the original appearance of the paste residue (ie, the paste appearance before drying)
Changed. Overlapping layers, the accumulated glue residue turned white. Within about 20 minutes, all layers of the residue were hydrated visibly and could be removed manually by peeling each layer from the cross member. When composition A reached the bottom of the residue that was estimated to form first over 20 years ago, the bottom could be removed and the equipment could be restarted. Overall, equipment maintenance problems due to glue residue were minimized. Prior to the application of Composition A, the only means to remove the preferably possible residue was to use only a hammer. Only a hammer was used to scrape the layer from the cross member part of the adhesive applicator.

Example 3
This example is another example of a composition of the present invention (referred to herein as “Composition A”) for removing organic and mineral residues from equipment such as anilox rolls used in flexographic printing processes. Explain the use.

Equipment utilized for anilox rolls was supplied by Packaging Corporation of America (PCA: Waco, Texas). The equipment has been in use for several years. An inherent problem existing in the flexographic printing process is that various contaminants tend to accumulate and combine with microscopic cells etched with a laser in an anilox roll. These cells are made of letterpress photosensitive resin plate (r
aised image photo-polymer printing p
water) and solvent-based ink for flexographic printing. After removal of the excess flexographic ink, the anilox roll is removed from the scalant (scala).
There are a number of techniques used to remove nts) and residues. PC
The anilox roll of the equipment of A cannot be easily removed by the aforementioned methods, such as the use of baking soda blasting and ultrasonic equipment,
It had deposits of various minerals and ink components.

As a first method, composition A is 145 for each 2.54 cm (1 inch) length.
Sprayed directly onto the surface of anilox roll cell having a cell density of The anilox roll was hydrated with composition A and left hydrated for about 5 minutes. Thereafter, a standard aqueous flexographic cleaning solution was used to wash away contaminants from the cell. The use of Composition A appears to have decomposed the combined minerals and deposits, and the combined minerals and deposits are removed by washing with a normal alkaline type of flexographic cleaning solution. Obtained. By this method, it was possible to restore the cell depth and cell volume of the anilox roll. Composition A allowed the cleaning of the anilox equipment of the printing press without the purchase of expensive cleaning equipment, thereby reducing downtime and the burden of capital expenditure on the PCA.

The second method of Composition A was by adding Composition A to a flexographic ink reservoir connected to an ink pump. The contact time was about 5 minutes, followed by flushing using a standard aqueous flexographic washing method. Prior to that, methods such as baking soda blasting and the use of an ultrasonic device were utilized, but only the anilox cell surface was cleaned. Composition A
Showed better performance compared to the above method and emptied the cell as if it were new.

Example 4
This example illustrates another method for preparing the compositions of the present invention.
68.70 L (18.15 gallons) of a 35 wt% hydrogen peroxide solution (obtained from FMC Corporation (Philadelphia, Pa.) As an industrial grade of 35 wt% aqueous hydrogen peroxide) .75 gallons of dissolved solids containing less than 0.1 ppm low solids water (PGT ink (Ceda

(70 ° F.)) and atmospheric pressure, resulting in about 208.2 L (55 gallons) of the inventive composition. This is hereinafter referred to as “Composition B” and the pH was about 2.2.

Example 5
This example illustrates the printing press feed sowing system of the composition of the present invention (hereinafter referred to as “Composition B”).
luton recirculating system)
The use to remove residues and bacterial growths and fungi from is described.

The press was obtained from the Rock Tenn Company (Waxahachie, Texas) and was equipped with a Man Roland feed solution circulation system. This is also called a dampening mechanism, and the mixer, cooler, and total water 757
. It included a circulator that included an approximately 113.6 L (30 gal) water storage tank with a capacity of 1 L (200 gal). The equipment was used almost continuously for about 20 years. A significant amount of mineral residues, such as sediments including, for example, calcium and lime deposits, and white, green, brown and various colors of hair algae that are common in the industry. Containing bacterial and fungal growths were observed. Various solvents were used in an attempt to remove the residue and growth before the residue accumulated and interfered with production. Common industrial products used to clean the circulation system of such printing presses are, for example, Varn
Sodium hydroxide, such as those sold by various chemical manufacturers, including International (a global chemical manufacturer that produces printing chambers and printing chemicals and sells the products worldwide) It included products containing glycol ethers and mixtures of various biocides.

However, the use of such solvents has not been successful in removing inorganic residues and bacterial and fungal growths. Inorganic residues and growths accumulated to such an extent that they hardened in the water piping and could not be removed. Piping was blocked, making production difficult. Additional options could be chosen to replace the water piping and / or flush the water system with bleach, but the amount of water that had to be consumed reached thousands of gallons. In addition, manufacturing problems due to bleach residue are difficult to solve, and as a result, the bleaching option is not preferred and has not been economically feasible.

An amount of 18.93 L (5 gallons) of Composition B described herein was provided in the following procedure. Composition B was poured directly into each of the six pans of the recirculation system in an amount of 0.473 L (1 pint). In contact of Composition B with inorganic residues and bacterial and algae growths, it is observed that within about 15-30 seconds, water immediately begins to flow in the return piping from the printing press to the recirculation system. The composition B was shown to remove various contaminants. Later, the water distribution pipes in the recirculation system were clogged and the water flowed easily. Thereafter, an additional 15.14 L (4 gallons) of Composition B was added to 113.6 L (
Added directly to a 30 gallon) water storage tank. Within about 15-30 seconds, water immediately
Observed to begin flowing in the return pipe from the printing press to the recirculation system, composition B
Has been shown to remove various contaminants. It was observed that the material removed by composition B contained paper waste, slime molds, fungi, algae, ink components, and the like. Approximately 132.5 L (35 gallons) of such material was collected in an empty container. In order to further facilitate the removal of dead algal and bacterial growth and mineral decay deposits and residues released and / or degraded by Composition B, about 757. 1 L (200 gallons) of fresh water was passed through the water system.

The recirculation system was then refilled with a standard feed solution having a pH of about 3.8. The printing press was immediately incorporated into the production process. The normal restoration time at the start-up was about 20 to 25 prints before production. After the use of the composition B, the restoration time at start-up was about 2 to 3 sheets. The improved start-up is believed to be because Composition B is at or near the recommended pH of the feed solution. Prior to the use of Composition B, previously used products included sodium hydroxide, glycol ethers and biocides, and some of these products included alkalis such as blowing agents or caustic soda. The pH of the residue in the aqueous system after use of a conventional cleaning product would normally be in the range of about 9-10.5. Thus, the pH of the feed solution is typically in the range of 3.8 to 4.0, and composition B has a similar residual pH.
Thus, the use of Composition B provides a direct benefit in terms of production capacity, print quality, and reduced water costs.

Example 6
This example illustrates the use of a composition of the present invention (denoted herein as “Composition B”) to remove contaminants from a swimming pool.

The experimental site is substantially free of chlorine and other chemicals.
Gallon) of swimming pool containing water. The swimming pool has a shallow side depth of about 0.91 m (3 feet) and a deep side depth of about 2.74 m.
It was a rectangle with a shape that was (9 feet). The swimming pool has been covered for about 9 months and has been dormant. Prior to treatment, the water was dark and had a strong odor. The surface portion of the pool in water is about 3.81 cm (1.
It was covered by the breeding of green algae with a thickness of 5 inches). The green algae seemed to cover materials like the underlying gray algae. Due to the growth of large-scale algae,
The bottom surface of the pool and the surface of the first and second steps of the pool were not visible. The filter medium contained in the swimming pool filtration system was diatomaceous earth. P of water
H was 7.2, and the water temperature was about 25.56 ° C. (78 ° F.).

Thereafter, an amount of 37.85 L (10 gallons) of Composition B described herein is formulated at a constant rate from a plastic bucket to the pool while walking along the edge of the pool from shallow to deep. Added to the pool by pouring things. About 20
After a minute, the color of the water changed to light green “bean soup”. Collapse deposits began to surface and the decay deposits looked like substances like green and gray algae. Water transparency continued to improve. After about 24 hours, the water is somewhat cloudy or “
The color was “milky”. Substances like green algae and gray algae were "killed" because the algae debris covering the bottom of the pool, along with some collapses floating on the surface, looked like white, thin decay deposits. It looked like. The pH of the pool was 6.8. Thereafter, an amount of flocculant of about 1.892 L (2 liquid quotes) to facilitate the removal of the emerging collapse deposits.
) Was added. About 72 hours after adding Composition B, the bottom of the pool was aspirated and the collapsed sediment that was sucked out was discharged to the area adjacent to the pool. The pH of the pool is 6.
It was 8. Tap water was added to the pool until the pH was 7.0.

Pool water was uncovered, hibernated and not circulated for two weeks. 2
After a week, the dissolved oxygen (DO) is 106 ppm, the water looks very clear (the bottom of the deep side could be seen), and the pump used to circulate the pool water is started, 1 The water in the pool was circulated for 2 hours a day. There was 5.08 cm of precipitation (2 inches) after 1 week (3 weeks after adding Composition B), D
O was 98 ppm. After another week (total 4 after composition B has been added)
After a week) DO was 44 ppm. Although the water remained clear, several small areas of green algae breeding were observed on the surface of the underwater part of the pool.

Thereafter, a “maintenance volume” 9.46 L of composition B described herein.
(2.5 gallons) was added by pouring from one plastic bucket into one end of the pool. After addition, DO was 100 ppm (this was the desired value) and the pH was 7.4. The pool has 9.46L (2.
A 5 gal) portion of Composition B was continued to be added.

Example 7
This example shows the effect of various increases in the concentration of the composition of the present invention.
Two experimental sites (1 and 2) were utilized to determine the toxicity of the composition of the present invention. Experiment site 1 was an outdoor garden pond containing a fiberglass skeletal tank approximately 1.524 m (5 feet) in diameter and containing approximately 1893 L (500 gallons) of water. The aquarium also contained soil, stones, some bricks, and 36 small fish. The water had a bad odor and was black.
Substances that look like black mold or algae covered the soil and stones at the bottom of the aquarium.

Thereafter, Composition B as described herein in an amount of 236.6 mL (8 fluid ounces)
Was added to the aquarium by pouring composition B from a plastic bottle directly into the water from one end of the aquarium. The water temperature during the addition was about 25.56 ° C. (78 ° F.). When added, the water immediately started to foam. Foaming starts at one end of the aquarium and is about 1
It spreads to the other end of the water tank in 5 minutes. After 24 hours, the water became clear and the bricks and stones contained in the aquarium were completely visible and no longer covered with black mold and algae. The debris decay deposits seemed to cover the bottom of the aquarium. The pH and dissolved oxygen values were not measured. 2-3 based on observation
It was found that 247.9 g (8 ounces) of Composition B applied weekly was the recommended dose.

Test point 2 includes 22.71 L (6 gallons) of crushed pestle gravel, 109
. 8L (29 gal) standard glass bath. The glass tank was filled with reverse osmosis water. The pH was 8. Growing means used in the aquarium were Gro-Lite bulbs (similar to sunlight)
(With V spectrum) and TETRA-MIN tropical fish food. The water was circulated through the glass tank for about 5 days without any chemicals, live fish or plants added. After 5 days, 24 small feeding fish (small
bait shop minnows) was added to the water and left for about 2 days (about 48 hours). Thereafter, composition B is in a ratio of 100 to the weight of 1 million water (ie 1
00 ppm). About 30 minutes after the addition, the dissolved oxygen concentration was 106 ppm. After 24 hours, the dissolved oxygen concentration was about 44 ppm, and an additional 200 ppm of Composition B was added. After 30 minutes, the dissolved oxygen concentration was about 210 ppm. Small fish were observed swimming near the bottom of the aquarium. After another 24 hours, the dissolved oxygen was 86
ppm. An additional 500 ppm of Composition B was added. Thereafter, the concentration of dissolved oxygen was not measurable. This is because the dissolved oxygen concentration is too high, and the titration means used (sodium thiosulfate) is blackened to prevent obtaining an accurate dissolved oxygen value. Even when sodium thiosulfate exceeding 600 ppm was used after 6 hours, the dissolved oxygen value was still not measurable.

No additional chemicals were added for 4 days. Ten days after the first use of Composition B, the fish present in the aquarium began to die at a rate of 1 per day during the following 2 weeks. About 3 fish scales appeared to spread away from the fish body. Four weeks after the first use of Composition B in the aquarium, the water was still very clear and there was no algal growth. The dissolved oxygen was 44 ppm.

The results shown in the above examples clearly show that the present invention is suitably applied in order to achieve the objectives and to achieve the above uses and benefits as well as those inherently provided. It shows.

Reasonable changes, improvements, and adaptations may be included within the scope of the disclosure and claims without departing from the scope of the invention.
