Researches were conducted on turbidity control by conventional treatment process from feeding optimization of inorganic coagulant,enhanced coagulation of high polymer coagulant aid,enhanced filtration of quadratic micro-flocculation in jar test,pilot test and full-scale test.

Application of micro-flocculation contacting filtration in oilfield wastewater treatment;

Study on micro-flocculation direct filtration process in domestic sewage;

Treatment of low-turbidity seawater with combination process of micro-flocculation and ultrafiltration;

Research on microflocculation and microfiltration for RO pretreatment of dyeing wastewater for reuse;

Study on the treatment of low turbidity wastewater by using microflocculation variable void deep filter;

The micropolluted reservoir water was treated separately with the microflocculation-ultrafiltration and the conventional treatment process of coagulation-sedimentation-filtration.

Application of BAF-micro flocculation process in printing and dyeing wastewater pretreatment and reclamation;

In this experiment the fiber-bundle is used as a filter medium for direct filtration of raw water under micro flocculation .

Based on the insight into the characteristics of oily effluents of mechanical and electrical machining industries, micro flocculation plus double bed filtration technology was chosen for the effluent treatment.
