Pretreatment equipment is mainly composed of: multi-medium filter, activated carbon filter, soft water machine, full automatic cleaning filter, ultrafiltration, microfiltration and dosing device. Different combinations can be chosen according to different water quality, different water uses and the needs of different industries.

Multi-medium filter: remove water particles, suspended matter, colloid and other substances. Effective reduction of sludge density index (SDI) of water;

Activated carbon filter: mainly adsorbed residual chlorine, organic matter, colloid and other substances in water, so that the effluent is better, effectively protect the RO membrane;

Soft water machine: mainly using softening resin to reduce the hardness of water, to reduce the possibility of RO film concentrated water structure measurement;

Fully automatic cleaning filter: operation and control without any external energy can automatically clean the filter, automatic discharge. The cleaning and filtration period can be adjusted, the default time of cleaning and filtration is 10-60/ s and the water loss of cleaning and filtration accounts for only 0.08 O.6%. of filtered water. Filter accuracy up to 10-3000 microns, working pressure optional 1. O 1.6 MPa： single flow :20& mdash;2500m3/h.. Can be vertical, horizontal, profile in any direction of any position installation.
