At R. R. Aqua Products Private Limited, we engineer water treatment systems that meet exact process specifications — not one-size-fits-all catalogue products. As an MSME-registered, DPIIT-recognised startup headquartered in Chennai, we deliver end-to-end EPC projects across Tamil Nadu and Pan India — from feasibility and detailed engineering to commissioning, training, and long-term Annual Maintenance Contracts (AMC).
Whether you are a plant manager sourcing a 1,000 LPH industrial RO system, an MEP consultant designing a DM water network for a new facility, or a hospital administrator ensuring BIS-compliant drinking water for 500 beds — this page details the technologies we deploy and how we size them.
Recovery Rate
50% - 85%
High-Recovery Desalination
1. Industrial Reverse Osmosis (RO) Plants
Reverse osmosis remains the most reliable, cost-effective method for reducing dissolved solids, hardness, heavy metals, and biological contaminants from raw water or bore-well supply. Our industrial RO plants are engineered around TFC (Thin-Film Composite) Polyamide spiral-wound membranes — the gold standard for high-recovery, long-life brackish water desalination.
Typical Pre-treatment Sequence
Multi-Media Filter (MMF)
Removes turbidity, suspended solids, and colloidal particles using graded sand and gravel beds. Protects downstream components from fouling.
Applications We Serve
Pharmaceuticals & API
WFI pre-treatment and process water.
Textile & Dyeing Units
Process water make-up and recycling.
Food & Beverage
BIS-compliant product water manufacturing.
Boiler Feed Water
Pre-treatment for high-pressure boilers requiring low TDS input.
IT Parks & Campuses
Drinking and process water for large residential/commercial campuses.
Healthcare Facilities
Dialysis-grade water pre-treatment.
Ultrapure Water < 1 µS/cm
2. Demineralised (DM) Water Plants
For industries where even the trace mineral content of RO-permeate is unacceptable — power plants, high-pressure boilers, electronics manufacturing, and the pharmaceutical sector — Demineralised Water produced by ion exchange technology is the answer. We deliver conductivity below 1 µS/cm.
SAC (Strong Acid Cation)
Exchanges cations (Ca²⁺, Mg²⁺, Na⁺) for hydrogen ions (H⁺). Outlet is dilute acid with all anions intact.
SBA (Strong Base Anion)
Exchanges all anions (Cl⁻, SO₄²⁻) for hydroxyl ions (OH⁻). H⁺ and OH⁻ combine to form ultrapure water.
Mixed Bed Polisher
Final polishing stage containing intimately mixed SAC and SBA resins to bring conductivity to <1 µS/cm (pharmaceutical grade).
Scale Sizing
500 to 50,000 LPH
3. Packaged Drinking Water Plants
Designed to meet BIS IS 10500:2012 and FSSAI standards, combining multiple treatment barriers to guarantee microbiological and chemical safety at every point of use.
- RO + UV (254nm): Inactivates bacteria/viruses without DBPs.
- Ozonation: Residual protection in storage tanks.
- Sanitary SS316L Piping: Orbital TIG welding eliminates biofilm crevices.
4. Industrial Water Softeners
Hard water destroys heat exchangers, boilers, and cooling towers. Our softeners use sodium-form Cation Exchange Resin (SAC-Na) to eliminate scaling tendency instantly.
- Cooling Towers: Lowers blowdown frequency and chemical cost.
- Low-Pressure Boilers: Prevents catastrophic tube failure.
- AMC Services: We offer fully managed AMCs across Tamil Nadu.
5. Grey Water Treatment & Recycling
Urban buildings and industrial facilities discharge significant volumes of grey water. Treating and recycling this water for toilet flushing and landscaping reduces municipal water dependency by 20–40%. We design compact units (MBR or trickling filter) meeting CPCB Class E standards for non-potable reuse.
