Commercial Water Filter Spare Parts RO Water Treatment 4021 ULP RO Membrane

In the practical application of reverse osmosis membrane separation technology, membrane fouling will inevitably occur. Membrane fouling is an important factor affecting the desalination rate, water production and water recovery rate of reverse osmosis membranes. The pollution prevention and treatment measures will be of great significance to reduce membrane pollution, improve the water production and water recovery rate of the reverse osmosis system, ensure the normal operation of the system, and prevent failures.

The boron removal performance of commercial brackish water reverse osmosis membranes was studied, and the effects of influent pH, pressure, temperature, NaCl concentration, boron concentration and membrane surface velocity on the boron removal performance of brackish water membranes were investigated. The results show that the boron removal performance of brackish water reverse osmosis membrane elements and membranes is basically the same under different test conditions. Among various influencing factors, the pH value of the influent water has the most obvious effect, and the boron removal rate increases significantly with the increase of pH value. Increase. Under the condition that the pH value is less than 10, the deboronation rate increases with the increase of the inlet water pressure; under the condition that the pH value is greater than or equal to 10, the deboronization rate is basically not affected by the inlet water pressure. The increase of NaCl concentration and the increase of NaCl concentration will reduce the boron removal rate. The boron concentration of the influent and the flow velocity of the membrane surface have little effect on the boron removal rate of the membrane.
