PURIFICATION TEST OF ELECTRIC DESALTING WASTEWATER BY INORGANIC MEMBRANE

Abstract

Abstract: An inorganic membrane was used to treat electric desalting wastewater. The influence of operation parameters on membrane flux was investigated, and the cleaning and regeneration experiments were carried out. The results showed that the optimum operating parameters are temperature (T+15)℃, pressure (P+100) kPa and flow rate (V+1) m/s. After filtration, the removal rate of COD, suspended solids and oil in the sewage was 74.77%, 91.67% and 84.42%, respectively. The contents of ammonia nitrogen and volatile phenol were decreased, showing the obvious effect of purification. With the extension of filtration time, the membrane flux was decreased. The recovery rate of membrane flux was as high as 97.3% after cleaning with RYT-02 cleaner.

Key words: inorganic membrane, wastewater, suspended substance, membrane flux
