RO (Reverse Osmosis) Plant

Reverse Osmosis (RO) Plants for Industrial & Commercial Water Purification

Clean, purified water is a fundamental requirement across nearly every industry — whether for process water, drinking water, or as a critical pre-treatment stage before further purification. Renora Hydrotech designs, manufactures, and installs high-performance RO plants that deliver consistent water quality for industrial, commercial, and institutional applications across Gujarat.

What is a Reverse Osmosis (RO) Plant?

A Reverse Osmosis plant purifies water by forcing it through a semi-permeable membrane under pressure. This membrane allows water molecules to pass through while blocking dissolved salts, contaminants, bacteria, and other impurities — producing clean, low-TDS permeate water on one side and a concentrated reject stream on the other. RO is one of the most widely used and reliable purification technologies for both drinking water and industrial process water applications.

How the RO Process Works

1. Pre-Treatment — Raw water passes through filtration (sediment filters, activated carbon) to remove suspended solids and chlorine that could damage RO membranes.
2. High-Pressure Pumping — Pre-treated water is pressurized and pushed through the RO membrane.
3. Membrane Separation — The membrane blocks dissolved salts and contaminants, allowing purified water (permeate) to pass through.
4. Reject Stream Management — The concentrated reject water is either discharged, further treated, or in ZLD setups, sent to downstream evaporation systems for complete recovery.
5. Post-Treatment (if required) — Additional polishing, such as UV disinfection or remineralization, can be added depending on the end-use requirement.

Our RO Plant Design & Delivery Process

1. Feed Water Analysis — We test your raw water source's TDS, hardness, and contaminant profile to determine the right membrane and pre-treatment configuration.
2. Custom System Design — Membrane type, array configuration, and recovery rate are engineered specifically for your water source and required output quality.
3. Fabrication & Quality Control — Systems built using corrosion-resistant materials and high-performance membranes suited for continuous industrial operation.
4. Installation & Commissioning — Complete on-site installation, testing, and performance verification before handover.
5. After-Sales Support — Membrane replacement, cleaning services, and ongoing maintenance to keep your RO plant operating at peak efficiency.

Maximizing Water Recovery with RO

Standard RO systems typically achieve 60–75% water recovery, meaning a portion of feed water becomes reject/concentrate. For facilities looking to maximize water reuse and minimize discharge, Renora Hydrotech can integrate your RO system with downstream MEE (Multi Effect Evaporator) units to further concentrate the reject stream — supporting Zero Liquid Discharge (ZLD) goals while recovering additional water for reuse.

Frequently Asked Questions

What is the typical water recovery rate for an RO plant?
Most industrial RO systems achieve 60–75% recovery, depending on feed water quality — the remaining reject stream can often be further treated using MEE systems for additional recovery.

How often do RO membranes need replacement?
With proper pre-treatment and maintenance, RO membranes typically last 3–5 years, though this varies based on feed water quality and operating conditions.

Can an RO plant remove all contaminants from water?
RO effectively removes the vast majority of dissolved salts, bacteria, and organic contaminants, though for ultra-high-purity requirements (like boiler feed or pharmaceutical use), RO is often paired with DM/Mixed Bed polishing.

Is pre-treatment always necessary before RO?
Yes — pre-treatment (sediment filtration, chlorine removal) is essential to prevent membrane fouling and extend the operational life of the RO system.

Can Renora Hydrotech design an RO system for both industrial and drinking water use?
Yes, we design RO systems for both industrial process water applications and potable/drinking water purification, tailored to the specific quality standards required.
