Ultra Filtration
Principal/Key Features
- Filtration to the tune of 0.1 to 0.01 micron
- Available in option of OUT–IN or IN–OUT
- Available in materials like PES, PVDF & PS
- Can be used in dead end filtration mode/cross flow filtration mode
- Removal of most bacteria & viruses from water
- Tolerance to Chlorine and so can be excellent for polishing of treated waste water
- Excellent choice for domestic/portable water purification needs
- Recommended solutions for pre-treated municipal water supply systems
- Very high rejection rate for wide area of contamination
- Very cost effective in long term
- Membrane last for 3–7 years

Major Applications Of UF
- Pretreatment to reverse osmosis (RO) systems to reduce SDI<3 to 5 and enhance the membrane life
- Post treatment as a polishing tool for fine filtration of treated effluent/sewage after sand and carbon filtration
- Heavy metal recovery/precious metal recovery like gold silver etc
- Excellent tool to meet the revised norms of environmental agencies/pollution control board/government agencies for existing systems
- Drinking water supplies of city, municipal, townships and institutional
Advantages
- Good and consistent quality of treated water in terms of particle and microbial removal
- Due to high recovery the water wastage is reduced to a great extent
- Maintenance cost is low
- Produce high quality feed water for RO systems enabling RO systems to operate at peak performance with reduced fouling and less cleaning
- Enhance treated effluent quality from secondary wastewater treatment process
- High solids tolerance is capable of handling high turbidity spikes and coagulant doses
- Lower chemical usage over comparable systems
