Advanced domestic RO water purification systems have been supplied and installed by PSD Energy & Water Pure System across homes, offices, and institutions in Karur and Tamil Nadu - delivering clean, safe, and healthy drinking water through a multi-stage purification process that removes 99.9% of dissolved impurities, bacteria, and heavy metals.

A domestic RO water purifier is a multi-stage water treatment system in which tap or borewell water is passed through a series of pre-filters, a reverse osmosis membrane, a UV steriliser, and a post-carbon polishing filter - producing clean, odourless, and safe drinking water that meets WHO drinking water quality guidelines.
At PSD Energy & Water Pure System, domestic RO systems have been supplied and installed across homes, offices, schools, and clinics in Karur and across Tamil Nadu - with capacities ranging from 10 LPH compact units to 75 LPH high-output purifiers suitable for large families and shared spaces.
"Tap water in many parts of Tamil Nadu has been found to contain TDS levels of 500–2000 mg/L, fluoride concentrations above permissible limits, and bacterial contamination - all of which are removed by a properly installed RO purification system."
A semi-permeable reverse osmosis membrane is used to remove dissolved salts, heavy metals, fluoride, nitrates, and microscopic contaminants down to 0.0001 micron - far beyond what sediment or carbon filters can achieve.
An ultraviolet sterilisation lamp is incorporated to deactivate 99.99% of bacteria, viruses, and pathogens that may survive the RO process - adding a critical layer of biological safety to every drop dispensed.
An ultrafiltration hollow fibre membrane is included as a final physical barrier - trapping any remaining suspended particles, cysts, and colloids before water reaches the storage tank.
A TDS controller allows a calibrated proportion of filtered water to bypass the RO membrane - blending essential minerals back into the output water so that healthy TDS levels of 80–150 mg/L are maintained.
A seven-stage purification process has been designed into every system - ensuring that water is filtered, purified, sterilised, and polished before it reaches your glass.
Sand, Rust, Silt, Suspended Particles
Water is first passed through a polypropylene spun sediment filter that removes physical particles down to 5 microns - protecting the downstream membranes from clogging and damage caused by large suspended impurities.
Chlorine, Pesticides, Organic Matter, Odour
Activated carbon is used to adsorb chlorine, chloramines, pesticides, and organic compounds from the water - eliminating unpleasant taste and odour while protecting the sensitive RO membrane from chemical degradation.
Scale-forming Minerals, Membrane Protection
Scale-inhibiting media is used in high-TDS water areas to prevent mineral scale deposition on the RO membrane surface - extending membrane life and maintaining consistent purification performance over time.
TDS, Heavy Metals, Fluoride, Nitrates, Bacteria
The reverse osmosis membrane - rated at 75 gallons per day - forces water through a semi-permeable barrier under pressure, rejecting dissolved salts, heavy metals, fluoride, nitrates, and over 1,000 other contaminants.
Cysts, Colloids, Residual Bacteria
An ultrafiltration membrane with 0.01-micron pore size is placed after the RO membrane to capture any remaining suspended particles, cysts, and colloids - providing a physical safety net for the purification process.
Bacteria, Viruses, Pathogens (99.99%)
Water is exposed to ultraviolet light at 254nm wavelength inside a stainless steel chamber - disrupting the DNA of any surviving bacteria, viruses, and microorganisms to render them biologically inactive.
Residual Taste, Odour, Final Polishing
A final granular activated carbon filter is passed through to remove any residual taste or odour from the storage tank - ensuring that the water dispensed is crisp, clean, and pleasant-tasting at the point of use.

Tap and borewell water in Tamil Nadu has been found to contain multiple contaminants that are harmful to health - none of which are visible to the naked eye, and most of which are not removed by conventional boiling.
Bitter taste, kidney stones, cardiovascular risk
Typhoid, cholera, gastroenteritis, diarrhoea
Dental fluorosis, skeletal damage in children
Blue baby syndrome, hormone disruption
Scale buildup, staining, metallic taste
Long-term cancer risk, immune system stress
All of the above contaminants are effectively removed or reduced to safe levels by a properly installed 7-stage RO purification system - protecting your family's health every single day.
A TDS meter test and visual inspection are conducted at your premises at no charge - identifying your water's current quality and contamination levels.
The right RO model, capacity, and stage configuration are recommended based on your source water quality, family size, and daily water consumption.
An itemised quote covering system cost, installation charges, warranty terms, and filter replacement schedule is provided before any commitment.
Trained technicians complete the installation - including wall mounting, inlet plumbing, drain connection, and pressure testing - within 2–3 hours.
Output water TDS is measured and confirmed, all fittings are checked for leaks, and the system is run through a full flush cycle before handover.
Annual Maintenance Contracts are offered covering scheduled filter replacements, membrane checks, UV lamp replacement, and performance verification.
Compared to packaged water cans, boiling, or simple filter pitchers - an RO purifier delivers superior water quality at a fraction of the long-term cost, with zero plastic waste and complete health protection.
