Abstract: Abstract:Several technologies, such as the dosing reaction sedimentation, the magnetic water circulating cross flow and the microfiltration, were combined adopted to treat the reverse osmosis concentrated water. The product water indexes are as below: hardness (expressed as CaCO3) ≤300mg/L, turbidity ＜5NTU, which meet the requirements of file GB/T 19923—2005 “The Reuse of Urban Recycling Water:Water Quality Standard for Industrial Uses”. The burden of the sequent reuse treatment unit was lightened, and the water utilization rate was improved.
