ИССЛЕДОВАНИЕ ЭФФЕКТИВНОСТИ БЕЗРЕАГЕНТНОЙ ЭЛЕКТРОМАГНИТНОЙ ОБРАБОТКИ ИСХОДНОЙ ВОДЫ НА НЕФТЕХИМИЧЕСКИХ ПРЕДПРИЯТИЯХ

A technological scheme and technical documentation for the manufacture of a test bench with a purified water capacity of 300 l/h have been developed. Long-term tests were carried out on a test bench, as well as analysis of the quality of the sampled water before purification, with the use of an electromagnetic treatment device and without it. As a result of the tests carried out, it was found that the total salt content after the reverse osmosis unit decreased from 535.5 to 30.0 mg / l, and in water with the use of magnetic water treat-   ment – from 535.5 to 12.7. Moreover, the pH in the first case varied from 8.3 to 6.2, in the second – from 8.3 to 6.44. It has been established that the use of magnetic water treatment in desalination before the reverse osmosis unit has a positive result, namely, calcium and magnesium salts do not settle on the reverse osmosis membranes, thereby prolonging the service life of the reverse osmosis membranes.   REFERENCES [1] Gusakovskij V.B. i dr.
