Bio-Chips For Advanced Biological Treatment
•
Biochips Reactor (BCRSM)
BCRSM systems maintain a robust biomass population on Bio‐Chip media suspended in the mixed liquor.
Movement of biofilm/carrier through solution increases performance and the rate of contaminant removal.
This efficient design provides tremendous treatment capacity in very compact tank sizes.
•
Benefits
Compact
Robust biofilm process
Easy to operate and control
No sludge return
WSI DAF System
Replace traditional system that consists of turbine, air compressor injector, static mixer, big pressure tank
Microbubbles (size 20 µm – 30 µm) generated through functions of suction, mixing and force‐feed.
