Reverse osmosis, is a means for separating dissolved solids from water molecules in aqueous solutions as a result of the membranes being composed of special polymers which allow water molecules to pass through while holding back most other types of molecules; since true "pores" do not exist in the membrane, suspended solids are also retained by superfiltration.

Some studies demonstrate that in cases where a treatment plant uses enhanced coagulation, ,manganese, contamination of the ferric chloride ,can, result in soluble ,manganese, concentrations of up to 0.5 mg/L. Typical levels of ,manganese, attributable to coagulant addition in surface ,water, treatment plants range from 0.025 mg/L to 0.055 mg/L. Release from solids in sedimentation basins typically ranges from 0.01 mg/L to 0.10 mg/L (with variations being observed seasonally), and ,manganese, …
