And separation of heavy metals and acids; separation of pigment intermediates and acid; separating chemical intermediates with a strong acid; and purify various wastewater purification and recycling: recycling technology and equipment applications industry wastewater acid purification. Advantages: high filtration precision, high retention of macromolecules; acid production directly reused after filtering, to avoid acid-base and subsequent treatment; continuous production of Nantong flat membrane, easy to operate; what can be achieved with the pH of the product separation. MBR membrane integrity film production affect the water quality of the water. Hollow fiber membranes rupture due to some reason, the water on the side of the raw water through a broken wire directly into the membrane permeate side of the membrane Xuzhou flat, resulting in poor water quality. Therefore, in practical applications should establish effective measures to detect the integrity of the film. Detection of membrane integrity measures are divided into two categories: direct and indirect. Direct method is based on the principle of the bubble point test, the membrane is completely wetted flat membrane, the membrane wire side (permeate side) pass into the lower than the bubble point pressure of the compressed air, due to the surface tension of the liquid in the membrane pores effect, due to diffusion through the addition of a very small amount of air, there is no significant gas flow through the membrane pore wetting. If the film or film defective wire breakage Yancheng flat membrane, then a large number of defects from the compressed air will pass through to the other side of the membrane, then if the other side is filled with liquid bubbles will be observed continuously. The indirect method is to install the turbidity in the ultrafiltration system produced pipes, by monitoring the quality of water used to indirectly monitor the integrity of the film.
