Abstract :
Micro-flocculation and continuous microfiltration (CMF) processes were used for pretreatment of reverse osmosis (RO), Using CMF and RO techniques, petro-chemical wastewater after secondary treatment was regenerated. The conductivity of the treated wastewater is below 100 μs/cm, oil is below 1 mg/L, turbidity is below 0.5 NTU, SDI is below 3, and the wastewaters all meet the requirement of RO inlet water. The conductivity of the treated wastewater is below 100 μs/cm, the desalinization rate of RO system is above 98%. Completely reach the water standard of the makeup water in the boiler.
