Ultrafiltration principle

Ultrafiltration is a thin film separation technology, rely on the fluid flow and pressure drive to cut the filtering process, and the molecular weight size to separate particles to pressure difference for driving force, raw material liquid in the membrane surface flow, raw materials of solvents and small fluid solute particles from high pressure liquid materials of low voltage side of the membrane through, soluble materials and small aperture than film material will can be used as a liquid membrane through through, the liquid through generally called filter out liquid or through liquid, not through the membrane material will be ultrafiltration membrane that capture, generally called the interception of concentrate, concentrate in filtering liquid concentration increases in the left, to the purification of the solution, separation and enrichment purpose.

Function introduction

Ultrafiltration is a membrane separation equipment. But than microporous membrane much smaller, belong to molecular level, it can filter out bacteria, viruses, colloid and small molecular weight that particles. It used in ordinary temperature, filter reliable performance, high precision, and does not need to add medicine that can reach the separation, purification and concentration of levels of purpose. It has simple structure, easy to operate, cover an area of an area small, easy to expansion and increase components, etc.

Technical characteristics

Ultrafiltration technology can be separation and purification, and the solution of concentrated goal, is a highly efficient, environmental protection, energy saving the separation process;

With a low pressure as a driving force, to realize the molecular size according to separate particles, such as water the preparation of mineral water, industrial water recycling recycle;

Ultrafiltration separation process in the temperature of the room temperature is near, low energy consumption, no phase change, in food processing, pharmaceutical industry, biological technology and other fields have a unique application value;

The scale of the ultrafiltration process and processing power to adapt to the wide, equipment structure compact, easy to other separation unit integration, and realize the automatic control. As OF + RO membrane method has become a desalination water treatment is recognized as one OF the best combination.
