Background technique

With the development of the economy, the situation of water resources has deteriorated in many places. The shortage and pollution of water resources have become more and more serious, and the problem of drinking water safety for urban residents has become prominent. Aiming at the secondary pollution of tap water in cities and the persistent presence of harmful substances in tap water due to source water pollution, more and more household water purifiers with reverse osmosis membrane as the core filter unit have entered thousands of households. The existing household pure water machine uses the reverse osmosis membrane as the core filter unit. After multi-stage pretreatment and pressurization of tap water, it enters the reverse osmosis membrane unit. The pure water produced can fully meet the domestic drinking water requirements of developed countries. standard.
