Yangtze River water → inclined pipe filter → raw water tank → ultrafiltration → ultrafiltration water tank → reverse osmosis → intermediate water tank → mixed bed → desalinated water tank → water supply
≧145T/H (25℃ water temperature)×3 groups
The reverse osmosis system needs to be chemically cleaned around 15 days after it is put into operation, and the security filter element needs to be replaced after 2-3 days of use.
A large amount of yellow sludge-like contaminants are found on the surface of the membrane element and on the surface of the filter element, with strong adhesion and fishy smell.
By optimizing the reagents in each process section of the system and adding our company’s Dispersant-8821 organic sludge stripper in a timely manner, the filter element pressure difference is quickly controlled in a short time, the filter element replacement cycle is extended to 2 months, and the reverse osmosis chemical cleaning cycle Extend to half a year.
