Comprehensive Sizing & Design Guide for Industrial RO Plants in Tamil Nadu

Engineering Industrial RO Plants for High Performance

Industrial Reverse Osmosis (RO) plants are critical assets for textile dyeing mills, pharmaceuticals, food processing plants, power generation units, and manufacturing hubs across Tamil Nadu.

Designing a robust industrial RO system requires careful consideration of feed water chemistry, daily throughput demands, recovery efficiency, and anti-scalant pretreatment.

Essential Pretreatment Modules

1. **Raw Water Feed Pump Skid**: Provides consistent inlet pressure and volumetric flow.
2. **Multi-Media Dual Pressure Sand Filter (DMF)**: Removes suspended solids, turbidity, and colloidal matter down to 20 microns.
3. **Activated Carbon Filter (ACF)**: Adsorbs free chlorine, organic contaminants, pesticides, and residual color.
4. **Dosing Systems (Anti-scalant & SMBS)**: Prevents mineral precipitation ($CaSO_4$, $BaSO_4$, $SiO_2$) on membrane surfaces and neutralizes oxidant chlorine.
5. **5-Micron Precision Micron Cartridge Filter (MCF)**: Final guard filter protecting high-pressure pumps and RO membranes.

Membrane Selection & Array Configuration

• **High Rejection Brackish Water (BW) Membranes**: Ideal for feed TDS from 1000 PPM to 5000 PPM, achieving 99.2% salt rejection.
• **High Pressure SS 316 / Vertical Multistage Pumps**: Delivers required osmotic pressure (15 – 25 bar).
• **PLC & CIP Automation**: Integrated Clean-In-Place skids allow chemical wash cycles without dismantling pressure vessels.
