Xiamen Weishibang Membrane Technology Co., Ltd. and Xiamen Lubang Membrane Technology Co., Ltd. have recently cooperated in the development of advanced treatment and recycling technologies for printing and dyeing industry wastewater. This kind of high-efficiency ultrafiltration system integrated by the hollow fiber porous membrane filtration module etc. makes up for the disadvantages of the general reverse osmosis system membrane that is easily fouled, has a strong anti-pollution ability, and has an energy-saving effect. The membrane assembly of the system is unilateral water discharge and aeration at the other side. U-shaped structure can increase the membrane area and enhance the self-cleaning capability of the membrane. The flow is short and the flux is large. The first use of the concentrated water circulation and two-way flow is adopted. Water technology has been applied in many printing and dyeing companies such as Shenghong Group.
