At present, the water source pollution is aggravated and the requirements of people on water quality are increasingly strict, the traditional water treatment process cannot ensure the safety of the water quality of drinking water. To solve this problem, it is often necessary to add a new water treatment unit on the basis of the conventional process or to enhance the conventional process, and the current membrane technology is considered as the most promising method, and has been widely used in the field of water treatment in recent years due to the reduction of material price and the improvement of performance.

The membrane coagulation reactor combines coagulation and membrane separation technology, and membrane separation is used to replace the precipitation and filtration unit in traditional technology. The coagulation can remove suspended solids and colloids in water, and the membrane separation can ensure that the turbidity of the effluent reaches the standard.
