The membrane filtration concentrate treatment method was patented for invention

A few days ago, the membrane filtration concentrate treatment method developed by China Petrochemical Research Institute was awarded an invention patent
.

At present, membrane filtration units such as ultrafiltration, nanofiltration and reverse osmosis have been widely used in the field of advanced sewage treatment, and the resulting treatment of membrane concentrate is also a new environmental protection issue
.
Researchers at Daqing Chemical Research Center of Petrochemical Institute have developed a new method
for treating membrane filtration concentrate using Fenton oxidation-flocculation-biochemical treatment combination process.
In this method, Fenton oxidation and enhanced flocculation precipitation are completed in the same container; No need to add flocculants and coagulants, high utilization rate of H2O2, low operating costs; Flocculants utilize Fe3+ produced by Fenton's oxidation process without additional dosing
