Reverse osmosis pretreatment system for raw water containing metal oxides

Preoxidation of raw water is set in the pretreatment system, and then iron and manganese ions and their compounds are removed from the raw water through coagulation, sedimentation and sand filtration or manganese sand filtration processes.

In the pretreatment system, additional lime pre-softening and coagulation, clarification, sedimentation of the combined treatment process can generally remove most of the metal oxides in the raw water.

Using electrochemical coagulation, sedimentation and multi-media filtration pretreatment combination process, can also remove most of the iron metal oxides in the water.

Adding chemical dispersant. While inorganic salt scaling can be effectively prevented, a certain amount of metal oxides can also be prevented from being deposited in the reverse osmosis membrane system.
