Identify the primary symptom of your source water below to navigate directly to the recommended solution:
Salty / Bitter Taste in Water
Water has high Total Dissolved Solids (TDS > 300 PPM) and dissolved chemical salts.
White Scaling & Severe Hair Fall
Borewell water has high calcium & magnesium hardness choking pipes and staining fixtures.
Bulk Water for Business & Staff
Need 250 to 20,000+ liters of certified pure drinking water daily for a workplace.
Red Rust Rings on Bathroom Tiles
Underground borewell water contains dissolved iron that oxidizes into yellow/red stains.
How to Size Your Water Purification System
Selecting the right capacity ensures consistent water pressure, eliminates premature filter choking, and optimizes operating costs.
Residential RO Purifiers (12 – 25 LPH)

| Technology | Primary Target Contaminants | Ideal Input Water TDS | Typical Application |
|---|---|---|---|
| Reverse Osmosis (RO) | Total Dissolved Solids (TDS), salts, fluoride, lead, arsenic, bacteria, viruses | 250 – 3,000+ PPM (brackish borewell) | Drinking water, commercial kitchen, dialysis, boilers |
| Ion-Exchange Softening | Calcium (Ca²⁺) and Magnesium (Mg²⁺) mineral hardness | Any TDS (targets hardness cations) | Whole-house bathing, washing, solar water heaters, laundry |
| Catalytic Iron Filtration | Dissolved ferrous iron (Fe²⁺), manganese, and rust sediment | Iron > 0.3 mg/L | Pre-treatment for borewells with red rust stains |
| Ultraviolet (UV) Sterilizer | Active biological pathogens, coliform bacteria, cysts | < 200 PPM (low TDS / municipal river water) | Microbial disinfection without chemical byproduct |
Frequently Asked Questions: Products & Ordering
Helpful answers regarding warranties, installation timelines, power consumption, and routine maintenance.
Do all water purifier and softener purchases include free installation?
Yes. Every water system purchased from Vinayaga Engineering includes complimentary doorstep delivery and professional turnkey installation by our certified plumbing and electrical engineers across Madurai, Trichy, Chennai, and all South Tamil Nadu districts.
How does your Free 1-Year AMC (Annual Maintenance Contract) work?
With our free 1-year comprehensive AMC, our service team conducts scheduled preventive maintenance visits, inspects membrane pressures, cleans pre-filter chambers, checks TDS calibration, and provides unlimited free breakdown support with zero labor charges.
What electricity and water pressure are required for an industrial RO plant?
Small commercial plants (50 to 250 LPH) operate on single-phase 220V power. Larger systems (500 LPH to 5000+ LPH) require a three-phase 415V electrical connection with an MCB breaker. Raw water inlet pressure should be at least 1 bar, typically provided by an overhead tank or raw water feed pump.
Can an iron remover and a water softener be installed together on the same borewell?
Yes. In fact, if raw water contains both high iron (>0.3 PPM) and mineral hardness, an iron removal filter must be installed upstream before the water softener. Unfiltered iron coats ion-exchange resin beads permanently, reducing softening capacity. Our engineers inspect and design the proper sequential stages.
