More and more enterprises choose ultrafiltration for water treatment. In foreign countries, ultrafiltration is mainly used in drinking water treatment, and many waterworks have applied ultrafiltration technology to produce tap water. In China, ultrafiltration is mainly used for wastewater treatment and reuse in the industrial field, and as a pretreatment for reverse osmosis (RO). At present, in the domestic water industry market, ultrafiltration technology has been widely used in the fields of electric power, steel, chemical and other industrial wastewater treatment. the

So far, most foreign external pressure ultrafiltration membrane products are 8-inch single-end water outlet hollow fiber ultrafiltration membrane modules. The method of opening the filtrate through the wire. And the length of the module is longer, generally 1.5 to 2 meters. This method of single-end water outlet of the membrane filament has a great influence on the water production of the membrane module. The test results show that when the length of the membrane filament is greater than 1.5 meters, the effect of the length of the membrane filament is significant. For example, when the inner diameter of the membrane filament is 0.6 mm and the length is 1.8 The water yield of the double-end water outlet membrane module is about 50-100% higher than that of the single-end water outlet membrane module. the

Therefore, research and development have ultra-low operating pressure, high strength, high pollution resistance, high membrane flux, wider water quality application range, stable water production, excellent water quality, and double-ended water outlet. Membrane modules and their corresponding application methods are the main direction of research and development of hollow fiber membrane and module technology in the future, and the market demand is urgent and the potential is huge. the
