Overview

Reverse Osmosis (RO) is an advanced membrane-filtration technology that removes dissolved salts, minerals, heavy metals, and contaminants from pre-treated wastewater. RO is one of the most effective solutions for industries seeking water recycling, reduction of freshwater consumption, and compliance with ESG and sustainability targets.


Cheme Advance provides fully engineered RO and water recycling systems designed for Malaysian industrial conditions. Our systems are built to handle challenging wastewater characteristics, minimise fouling, optimise energy usage, and ensure stable long-term operation. When combined with MBR or other pretreatment systems, RO can recover a significant portion of wastewater and convert it into clean, reusable permeate suitable for various industrial applications.


In industries with high water demand, RO recycling is no longer optional — it is a strategic necessity to improve resource efficiency and remain competitive.

Industry Challenges This Solves

Industries with water-intensive processes face consistently rising water tariffs. RO recycling helps reduce dependency on municipal water or groundwater sources.

Less recycled water means higher:


  • Water bills
  • Wastewater discharge volume
  • Chemical consumption
  • Sludge generation

RO significantly cuts these costs.

Industries such as electronics, pharmaceuticals, and food & beverage require high-purity process water. RO provides a consistent, controlled source of clean water.

Some industries produce high dissolved solids or non-biodegradable compounds that cannot be removed biologically. RO effectively removes dissolved contaminants, ensuring compliance.

Global supply chains increasingly require water reuse and environmental stewardship — RO systems help industries meet these expectations.

What RO Does

Reverse Osmosis functions by applying pressure to push water through a semipermeable membrane, which filters out dissolved contaminants.


RO removes:

  • Total dissolved solids (TDS)
  • Salts and minerals
  • Heavy metals
  • Hardness
  • Colour-causing organics
  • Microbial contaminants
  • COD components

The result is:
✔  High-quality permeate suitable for reuse
✔  Concentrated reject water for disposal or further treatment

How the RO Recycling Process Works Step by Step

1. Pretreatment

Wastewater passes through MBR or filtration systems to remove solids and organics.

2. Cartridge Filtration

Fine particulates are removed to protect RO membranes.

3. High-Pressure Pumping

Water is pressurised to push it through the RO membrane.

4. Membrane Filtration

Contaminants are rejected and discharged as concentrated brine.

5. Permeate Storage

Clean water is stored for reuse or further polishing.

6. CIP (Cleaning in Place)

Automated acid/alkaline cleaning removes membrane fouling when required.

This integrated process consistently produces high-quality recycled water.
