Nirmal Aqua is a manufacturer of water purifiers are particularly designed for masses to give pure water at low cost, Maintenance free and No electricity required. We are engaged in providing our customers with a skillfully designed range of Water Purifiers. These water purifiers helps in intelligently removing bacteria, viruses and other dissolved physical impurities.
BARC (Govt. of India) has developed Ultra filtration Membrane technology water purifiers. Nirmal Aqua purifies all physical, chemical & microbiological impurities. The membrane (polysulfone material) filtration process in which the porosity is 0.01 micron that eliminates bacteria & Viruses. Along with it, activated carbon functions by removing complete odor, color & other chemical impurities that are highly dangerous & toxic for human health.
In the UV based water purifiers only the DNA of bacteria is deactivated & it cannot kill the viruses the decayed bacteria & turbidity remain in the UV treated water. As far as the reverse osmosis process is concerned, the water purifiers which use this technology remove even the total minerals & salt.

Information of Ultra Filtration Technology
Devices based on Ultra filtration Membrane can physically remove, bacteria, suspended solids and high molecular weight organics without the use of electricity, at tap water pressure, mainly by sieving ( size-exclusion)) mechanism. Useful life of this membrane device depends on configuration of membrane. Most of the existing membrane devices employ UF membrane in either spiral, capillary or hollow fibre form. Draw back with these configurations is that they can not be completely cleaned physically and due to deposition of suspended solids, their output keeps on decreasing with time. On line domestic water purifier developed at Desalination Division, BARC is based on this ultra filtration membrane in cylindrical configuration which is free from these limitations.
Uf Membrane
UF Membrane separate the species from effluent/water based on size exclusion mechanism. These membranes have the pore sizes in the range of 2-100 nanometers (nm), depending upon type of polymer and procedure used for fabrication of these membranes. Since these membrane pore sizes are much smaller than the sizes of bacteria (500- 3000 nm) , these membranes can be used as an absolute barrier to filter out bacteria and suspended solids. By coupling this with an activated charcoal column, other contaminants like colour, odour, organics and residual chlorine also can be removed from water supplied for domestic consumption.
Advantage of the device developed by BARC
- Ultrafiltration membrane device for domestic water purification has following advantages over various other devices for said purpose.
- The device is very effective. It almost completely filters out bacteria and turbidity, producing crystal clear water.
- The device is very compact and portable. It can be easily installed and needs no electricity or addition of any chemical.
- The device physically filters out bacteria. There will not be any dead or decayed bodies of bacteria in purified water unlike ultraviolet or chemical addition devices.
- Due to candle like cylindrical configuration of ultra filtration membrane, they can be easily cleaned and reused number of times unlike ultra filtration membrane of hollow fibre, capillary or spiral configuration which cannot be cleaned completely and has to be replaced after some time.
- The operational cost of device is almost negligible. It is almost maintenance free except occasional cleaning of membrane surface.
- Polysulfone, the material of preference for making ultra filtration membranes, has excellent stability with respect to residual chlorine acids and alkalis.
- No additional column of activated charcoal is required.
- Not a single drop of water wasted.
