By applying film-treatment technology in waste water, we break down the traditional water recycling model. This technology ensure the water meet the national reusing standard after pre-treatment and film treatment(O/I) with 60% reuse rate.

According to the following data we can see that during producing pure water for PCB production, it ensure middle-phase water can be reused. By producing pure water from waste water, we reduce the cost by RMB0.34 per cube/cm. This equipment can reduce waste water treatment cost and pollution significantly. As a result, corporate able to achieve the aim of environment protection and also increasing capacity but not pollution.
