1. Product introduction of hollow fiber ultrafiltration membrane


Hollow fiber ultrafiltration membrane is the newly developed and designed wastewater treatment and recycling technology in recent years. With the rapid development trend of world economies of scale and the increase of population, water shortage has become an unoptimistic challenge faced by people all over the world. In order to solve the problem of water shortage that plagues human development, the development of available water resources is a common concern of all countries in the world. Many waters in China regard wastewater reuse as one of the key development strategies to deal with water shortages.

2.The advantages of hollow fiber ultrafiltration membrane


Since ro uf membrane is used to replace the secondary settling tank in the traditional activated sludge process, it can be used for high-efficiency solid-liquid separation equipment. advantage

(1) Solid-liquid separation equipment can be developed efficiently, and the effluent water body is excellent and stable, and can be reused immediately;

(2) Due to the high efficiency interception effect of hollow fiber ultrafiltration membrane, the microbial strains can be completely intercepted into the membrane bioreactor, completing the complete separation of the hydraulic retention time (HRT) and sludge age (SRT) of the tubular reactor, making the operation more flexible and stable

(3) Membrane bioreactor can keep the concentration of microbial strains high, and solve the problem of large capacity load and large area of equipment;

(4) It is conducive to the interception and growth of nitrifying bacteria and other microbial strains, and improves the efficiency of the system software nitrification reaction. It can also increase the hydraulic retention time of some refractory organic compounds in the system software, and reasonably keep the microbial strains that dissolve refractory organic compounds in the tubular reactor, which is conducive to the efficient degradation of refractory organic compounds;


(5) Ro uf membrane Generally, it runs under high capacity load and low sludge concentration, and the remaining sludge output is low, which reduces the cost of sludge treatment;

(6) The automatic control system is convenient, and the actual operation and management method is convenient.

At present, hollow fiber ultrafiltration membrane has been widely used in wastewater treatment engineering projects, and the ultrafiltration membrane technology are used to realize wastewater recycling and reuse, and realize the two-way economic benefits of low carbon, environmental protection, energy saving and consumption reduction.
