Technical Field

[0001] The utility model relates to the field of regulating tanks, in particular to a regulating tank for reverse osmosis concentrated water defluorination processing. Background Art

[0002] Reverse osmosis concentrated water defluorination is a specific water treatment technology used to remove fluoride ions from water. This technology is mainly based on the working principle of reverse osmosis membrane. By applying a pressure higher than the natural osmotic pressure, the fluoride ions in the raw water are pressed to one side of the semipermeable membrane, thereby achieving the removal of fluoride ions. The reverse osmosis concentrated water defluorination regulating tank is a device specially used to treat fluoride-containing concentrated water. Its core function is to effectively remove fluoride ions from water through reverse osmosis technology. When the existing regulating tank is inlet, due to the influence of impurities in the inlet water, its reverse osmosis membrane is easily contaminated during operation, reducing the overall treatment effect; so we proposed a reverse osmosis concentrated water defluorination regulating tank to solve the above problems.
