Industries around Chennai face a difficult water source. Borewells near the coast and in many industrial estates carry high TDS, chlorides and hardness, and tanker water quality changes from load to load. Yet boilers, cooling towers and production lines need consistent, low-TDS water every shift. Intellect Aqua designs industrial reverse osmosis (RO) plants in Chennai that handle tough feed water and deliver stable output, backed by our Chennai service team.
Applications of Industrial RO
- Boiler feed water: Reduces scale and corrosion; often followed by a DM or mixed bed for high-pressure boilers.
- Cooling tower make-up: Low-TDS make-up lets towers run at higher cycles, saving water and chemicals.
- Process water: Automobile paint shops, electronics, pharma, food and beverage, textile washing.
- Product water: Packaged drinking water and beverage units.
- Effluent recycling: Recovering water from treated effluent as part of ZLD.
Designing RO for High-TDS Chennai Water
Detailed Water Analysis
We test TDS, chlorides, sulphates, hardness, silica, iron, turbidity and organics. In coastal areas, TDS can be much higher than inland borewells, which changes membrane selection and pressure.
The Right Membranes and Pressure
Brackish water with high TDS needs high-rejection membranes and higher-pressure pumps. Very saline water may need a seawater-grade design. We run membrane projections to choose the right array and recovery.
Robust Pre-Treatment
Multigrade filtration, activated carbon, softening or antiscalant, and ultrafiltration where needed protect membranes from scale, iron and fouling.
Corrosion-Resistant Construction
Salt-laden air and saline water corrode ordinary steel. We use SS high-pressure piping, FRP vessels and properly coated skids.
Automation and Monitoring
PLC control with online conductivity, pressure and flow monitoring, auto flushing and alarms keep the plant stable and make performance trends visible.
Our Design Process
- Water analysis and site study
- Definition of output quality and daily demand
- Membrane projection and recovery optimisation
- Pre-treatment selection
- Proposal with capital and running cost
- Fabrication, installation, commissioning and training
Common Industrial RO Problems We Fix
- Output dropping within weeks of cleaning
- Permeate TDS rising steadily
- Scaling on last-stage membranes
- Iron or biofouling from poor pre-treatment
- High-pressure pump failures from corrosion
We diagnose with water tests and normalised performance data, then fix the root cause — not just clean and hope.
Managing Reject Water
High-TDS feed water produces concentrated reject. Depending on quality and local rules, reject can be reused for scrubbers, floor washing or sent to further treatment. For units that cannot discharge, we integrate reject into a ZLD system.
Running Cost of an Industrial RO Plant
The main running costs of an industrial RO plant are electricity for the high-pressure pump, antiscalant and cleaning chemicals, cartridge filters, membrane replacement over time and the cost of handling reject water. With high-TDS Chennai water, pump power and membrane care matter even more. We reduce these costs by:
- Selecting energy-efficient pumps and, where suitable, variable frequency drives
- Optimising recovery so less water is wasted without risking scale
- Strong pre-treatment that extends membrane life
- Normalised performance tracking so cleaning is done at the right time, not too early or too late
Every proposal includes an estimate of cost per cubic metre of treated water, so you can compare options and plan budgets.
Standby and Redundancy
For critical applications like boiler feed and continuous production, we design plants with standby pumps, parallel trains or adequate treated-water storage so a breakdown or cleaning cycle does not stop production.
