- Combination of micro/ultrafiltration with a biological process
- Use of perm-selective or semi-permeable membrane, porosities ranging from 0.035 microns to 0.400 microns (depends on the manufacturer)
- Reduced procedures such as secondary clarifiers and tertiary treatment
- Advancement of organic and suspended solids elimination by immersing membranes into aeration system
- Membranes in charged of solid/liquid separation through membrane pores
- Biological processes support higher concentration of mixed liquor suspended solids (MLSS) hence reduce tank capacity
