BioCleaning® biochemical treatment of high-salinity wastewater technology
This process uses high-salinity tolerant microorganisms to treat the ammonia nitrogen, total nitrogen, BOD5 and other pollutants in salinity wastewater into stable and harmless nitrogen, carbon dioxide and water.
Technical Advantages
- The self-domesticated and cultured high salt-tolerant microorganisms could still maintain high activity at 8%wt salt concentration;
- It produces no sludge particles compared with traditional activated sludge;
- Microorganisms are added at one time without additional feed;
- Microorganisms reproduce and form membranes quickly.
