In the past 30 years, ultrafiltration membrane technology has developed rapidly and is often used in drinking water production, food industry, pharmaceutical industry production, and industrial production wastewater treatment industries. Ultrafiltration membrane technology generally focuses on the following aspects: drinking water supply terminal equipment, surface water treatment, seawater treatment and liquid recovery.
(1) Drinking water treatment.
Due to stricter requirements for drinking water quality, sewage treatment companies are investing more and more time to control the number of bacteria in the water supply network. In order to better ensure this, one method is to conduct expensive and frequent water body inspections, or to set up a natural barrier on the water supply terminal equipment to prevent bacteria from entering.
(2) Surface water treatment.
In fact, sewage discharged from sewage treatment stations and manufacturers in big cities is a good source of industrial water, even drinking water. Technically speaking, this is completely achievable, but customers in Western countries really can't believe this approach. This is not so much a technical difficulty as it is a psychological difficulty. However, currently Windhoek in Namibia has basically constructed an 850 tons/hour water plant, that is, the ultrafiltration membrane technology is selected to recycle the effluent from the sewage treatment station as drinking water.
