The emulsive liquid wastewater is wide-ranging used in machining. However it will be high both on the density and content of oil when should be discarded

moreover

this substance is so harmful to the environment. The emulsified oily wastewater is difficult to treat because of the existence of the surfactant. Through the semiconductor filter system bearing factory wastewater the removal rate of COD can reach 99.9%

the effluent can be reduced to 30mg/L COD. The advantages of this technology are high efficiency

stable running and low investment

especially suitable for emulsive liquid in middle and small scale mechanical processing plant.
