AI Technical Summary

Technical Problem

When the existing nanofiltration membrane reverse osmosis treatment device treats water containing impurities such as suspended substances, colloids, organic matters, it is easy to cause membrane contamination and blockage, affecting the treatment effect, and the membrane needs to be replaced regularly, which increases maintenance costs.

Method used

A nanofiltration membrane reverse osmosis treatment device for desalination water system is designed, including a dosing tube and a rotating assembly. The dosage of the dosage is controlled by the rotating assembly to reduce the contamination of impurities on the membrane; a sloped plate is provided to speed up the water treatment efficiency, and the service life of the membrane is improved by optimizing the design.

Benefits of technology

It effectively reduces the probability of membrane contamination and blockage caused by raw water impurities, reduces the frequency of membrane replacement, reduces maintenance costs, and improves the efficiency of water treatment.
