DEVICE FOR STABILIZATION OF pH OF WATER IN GROWING AQUATIC ORGANISMS IN INSTALLATIONS OF CLOSED WATER SUPPLY Russian patent published in 2019 - IPC A01K63/04 G05D21/02 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural production and can be used in closed water supply installations, intended for the cultivation of aquatic organisms. In the method, the device for stabilizing the pH of water includes unit of level automation and program control 1, containing an IBM-compatible computer where the computer program titled "Program for controlling water parameters in closed water supply installations" is installed. First communication-switching output of level automation and program control unit 1 is connected to communication-switching inputs of circulation pump 4, unit for moving sediment fractions 12, first gate 13 and second gate 14. Second communication-switching output of unit of level automation and program control 1 is connected to communication-switching input of conveyor 3. Third communication-switching output of unit of level automation and program control 1 is connected to communication-switching input of unit for dry soda-containing substance 2. Fourth communication-switching output of unit of level automation and program control 1 is connected with communication-switching inputs of water drainage unit with a pH concentration greater than 7.8 8 and water supply unit with a pH concentration of less than 7.05 10. First communication-switching input of unit of level automation and program control 1 is connected to communication-switching output of aeration channel 6. Second communication-switching input of unit of level automation and program control 1 is connected with communication-switching outputs of unit for dissolving soda-containing substance 5, second unit for settling water 7 and first unit for water sludge 9. Third communication-switching input of unit of level automation and program control 1 is connected to communication-switching output of unit for dry matter content 2. Output of unit for dry soda-containing substance 2 is connected to input of conveyor 3, and outlet of conveyor 3 is connected with first input of unit for dissolving soda-containing substance 5. Second input of unit for dissolving soda-containing substance 5 is connected to outlet of circulation pump 4. Third input of unit for dissolving soda-containing substance 5 is connected to outlet of water supply unit with a pH concentration of less than 7.05 10, whose input is connected to outlet of aeration channel 6. First outlet of dissolution unit of soda-containing substance 5 is connected to inlet of circulation pump, and second outlet of dissolution unit for soda-containing substance 5 is connected to inlet of first water-settling unit 9, whose output is connected to inlet of second water-settling unit 7. First output of second unit for water sludge 7 is connected to input of first gate 13. Second outlet of second unit for water sludge 7 is connected to inlet of water drainage unit with a pH concentration greater than the value of 7.8 8, and its output is connected to inlet of aeration channel 6. Output of first gate 13 is connected to input of second gate 14 and to input of sludge transfer unit 12, whose output is connected to input of sludge removal 11, and its output is directed to recovery.

EFFECT: technical result of the invention consists in reducing waste of aquatic organisms during their growth.
