We are a leading name in the field of Nano filtration systems that are similar to reverse osmosis and are aimed towards removing only divalent and larger ions, thus making these systems useful for desalting of process streams. The Nano filtration membrane technology is pressure based technology that is meant for the separation of soluble ions from water by use of semi permeable membrane where it produces same quantity product at 50 to 70% of the applied pressure as RO.

These Nano-filtration systems make effective use of high pressure for the separation of contaminants from water supply. As water is forced through membranes having tiny holes(.0001 micron in size), bacteria, viral contaminants, VOC’s, SOC’s and other unwanted water contaminants are effectively removed. Further, these systems also have in them water softening capabilities that involves removal of hardness ions like calcium and magnesium.

Applications of nano filtration are:

• Removal of heavy metals from wastewater
• Removal of pesticides from groundwater
• Wastewater recycling in laundries
• Water softening & nitrate removal

Benefits of Water Nano-Filtration Systems:

• Low cost operations with much lower discharge and waste water generation in comparison to other similar plants
• Delivering high reductions in heavy metals, TDS and fluoride
• Actively removing bacteria, VOC’s, pesticides and viral contaminants from water
• Causing reduction of nitrates, sulfides and salt content
• Allow chemical-free filtration
• Ideal for correcting water supply from municipality, wells, rivers and rain water
• Effective removal of iron, lime and other harmful chemicals
• Allows minerals essential for health to pass through
• Matching up with demands of constant water supply
• Lowest waste water with processed water superior in taste
• Lowering operating costs and less maintenance

Other Benefits:

• Increasing working efficiency of systems
• Increase system service life and ensuring lower maintenance costs
• Lowering energy costs with increased productivity

Ultrafilteration system for treating high  TSS & High SDI water. (River water,lake water,Industrial effluent)

We are leading names in the field of offering competitive solutions for Ultra filtration systems. These are systems based on separation process using membranes having pore sizes in range of 0.1 to 0.001 micron and provide assistance in removing colloidal materials, high molecular-weight substances as well as organic & inorganic polymeric molecules. The Ultra filtration membranes used in these systems have flux varying between 50 and 200 GFD at operating pressure of about 50 psig.

In the filtration process, Ultra-Filtration (UF) utilizes trans-membrane pressure differential for separating particles as per molecular weights. The raw water particles are smaller than pore of UF membrane get permeate and particles larger than UF membrane pore size get separated as concentrate under applied pressure.

UF Membrane Construction

• It is asymmetric semi-permeable membrane made using high molecular material
• The hollow fiber tubes are covered by micro-pores that allow solutions flowing in/out the membranes under influence of pressure
• UF membranes have pore sizes from 0.1 to 0.005 µm for different applications
• Normally, this process is utilized in removing-
  - High molecular-weight substances
  - Colloidal materials
  - Bacteria
  - Organic/inorganic polymeric molecules

Advantages
The noted advantages of UF Filtration membranes include:

• Require minimum pumping energy, thus providing saving on energy
• Offering chemical resistance over wide PH range
• Easy to operate & maintain with low investment costs
• Recovery ratio up to 98%
• Automation Grade are avabile in both automatc and semi automatic

Industry Applications
Some of the industries these are used in include:

• Surface Water Clarification
• RO Pre-Treatment
• Waste Water Treatment
