- An ozone generator can be incorporated into the water inlet that enhances the destruction of the microorganisms present and oxidizes the undesirable components of the water.
- the wastewater purification equipment of fruit and vegetable plants and phytosanitary treatments in the field which is the object of the invention, basically includes the following elements:
- a decanting tank of a truncated conical type and made of polyester reinforced with fiberglass, with a capacity of 500 1. approximately.
- This deposit will consist of two or more exits at different heights for clarification, one of which is arranged at the beginning of the conical base and another at a higher level and more specifically 50% of the height of the cylindrical part of said deposit. It has a flocculant dosing system and an agitator to produce a good mixture.
- a sludge filtration system arranged at the exit of the tank, passing to a filter bag of approximately 820 mm in length and 180 mm in diameter, made of monofilament nylon and with a step of 60 to 75 microns.
- the filtered product in the filter bag passes to a collection tank of approximately 50 1 and from here it is pumped to an intermediate tank of similar dimensions to the decanter. From the intermediate tank the filtered product passes to a self-cleaning ring filter, 75 microns in step and then has to pass through a few columns of activated carbon, usually in number from 1 to 3, of the order of 300 1 volume and containing approximately 100 kg of coal. They are made of polyethylene with outer reinforcement of fiberglass and epoxy resin.
- an ultraviolet lamp is incorporated to guarantee a greater degree of purification.
- the system incorporates a backwash mechanism that allows to obtain a higher yield of the active carbon columns.
- Figure 2. It is another schematic view, similar to Figure 1, incorporating an ultraviolet lamp.
- Figure 3. Shows an installation to carry out the purification process, including a pressure filter with filter bags prepared with a diatomaceous earth prelayer.
- Figure 4.- It is a perspective view of the rotating support holder of the activated carbon bottles.
- the wastewater purification equipment of fruit and vegetable plants and field phytosanitary treatments includes a system of decantation of wastewater from fruit washing drains . Its function is to separate the suspended solids that the residual water contains, being composed of a decanter 1 to which the waste water arrives and where flocculant can be added by means of the flocculation system 2, mixing with a stirrer 3. After the decantation the sludge from the bottom of the tank and the clarified water is transferred to the intermediate tank 7.
- the filter bag 5 is arranged in an upright position inside a metal frame 4 that serves as a fastener and collector of its permeate to the collection tank 6. This permeate is pumped from the tank 6 to an intermediate tank 7, where joins with clarified water.
- the dryness of sludge achieved through the filter bag system is of the order of 50%.
- the clarified water and the permeate of the filter bag, collected in the intermediate tank 7, are pumped through the ring filter 8.
- This filter acts as a safety filter for the activated carbon columns, retaining the solids remaining in the water.
- the equipment also includes the active carbon columns, in number of 3 in this exemplary embodiment shown in the scheme.
- the clarified water after passing through the safety filter 8 reaches the columns of activated carbon 9, where it will be purified by adsorption, eliminating toxic substances up to the limit values set by the Legislation.
- the light alarm system 10 will indicate the exhaustion and convenience of replacement of the first column of activated carbon 9.
- Reference 11 designates the necessary pumps and valves.
- the approximate yields achieved in the carbon columns are of the order: Suspended solids: 90% COD: 85% I azalyl: 100% Thiabendazole: 100%
- the ecotoxicity values of the purified water will be less than 2 TU
- the decanting system of the final broth from drains has been referenced with A, which is accessed through the loading mouth of the settling tank 1, as shown by the arrow.
- the block of activated carbon columns 9 is referenced with B.
- the block referenced with C corresponds to the sludge treatment system.
- the arrows shown in the diagram indicate the route of the product to be purified, through the installation; obtaining the treated water at the exit of block B of columns of activated carbon 9.
- Fig. 2 an installation is shown schematically that includes the ultraviolet lamp 13 that guarantees a greater degree of purification, the product being collected in the tank 12, from which it exits towards the drain.
- the dimensioning of the components of the equipment has been determined for a volume of trencher broth to be purified, of 4601 / h, and must be sized for different flows and polluting loads.
- the agitator 3 is connected, as well as the closed-loop pump through bag filter 15 and key 14a. Then the diatomaceous earth is gradually added and the recirculation is maintained for a minimum of 5 minutes. After the recirculation time has elapsed - The lotion, the filter bags 5 of this pressure filter 15, are prepared with a pre-ground of diatomaceous earth ea.
- the solenoid valve 14a is closed and the number 14b is opened, so that the lia pump proceeds to aspirate the broths to be purified and introduces them into the tank 6 with a solids filtrate of less than 50 microns.
- the objective is multiple:
- the pump 11b is started by driving the broths through three bottles 9 of activated carbon that define the battery of columns 9, these having a volume of the order of 316 1 each .
- a minimum stay of two hours of the broth must be guaranteed inside the bottles 9 of activated carbon, for which there is a liter counter with electronic output connected to an electric automatism that prevents the pump from continuing to drive broth until the one that is found inside the bottles 9 a minimum of two hours have remained inside them.
- this volumetric meter will be in charge of notifying the need to replace the active carbon of the first bottle 9 when it reaches its depletion, being able to connect a telephone alarm so that the supplier company proceeds to the change.
- the equipment has been designed to be able to incorporate a fourth bottle 9 of activated carbon, as shown in Figure 4. In this way it would be possible to easily replace the third bottle with the spare one; pass this third bottle to the previous position; occupying the second bottle the first position, once the colmatada has been removed.
- These four bottles 9 are in a turntable 17, this entire permutation process being carried out by a simple motorized or manual rotation of 90 - as is easily deduced when observing the figure.
- the control of the equipment is carried out by a programmable automaton connected to a touch screen that allows the user to program all the operating parameters of the equipment, with flow records and consumptions, notices of substitutions, etc., allowing its connection to a personal computer for greater versatility of handling, and this in turn to another remote via modem allowing remote control.
- the first filter bottle 9 incorporates a backwash valve 18 which allows this process to be carried out in case the active carbon of the first bottle 9 is caked, since it is the one that suffers the greatest polluting load. This process can be performed automatically once the differential pressure between the inlet and outlet exceeds a certain value. The result of the backwash is returned to the tank 6 to be treated as another part of the broth to be purified.
- the broths leave the bottles 9 of activated carbon, optionally the broth before being poured would be treated by ultraviolet lamps 13 and / or an ozonator 19.
- Reference 20 of Figure 3 designates a flowmeter.
