OZONE GENERATOR SYSTEMS

Advanced Oxidation for Colour Removal, Disinfection & Odour Control in Industrial Wastewater

Overview

Ozone Generator Systems are powerful advanced oxidation technology used to remove colour, reduce COD, disinfect water, and neutralise odours. As industrial wastewater becomes more complex — containing dyes, pigments, surfactants, solvents, and non-biodegradable organics — ozone is increasingly relied upon as a clean, chemical-free polishing method.


Ozone (O₃) is one of the strongest oxidants available, outperforming chlorine and peroxide while leaving no harmful chemical residues. When properly integrated into an Industrial Effluent Treatment System (IETS), ozone significantly improves effluent clarity, stability, and odour control.


Cheme Advance designs ozone systems specifically tailored to the needs of Malaysian industries. Our systems include proper injection, contact tank design, gas destructors, and safety controls to ensure stable, reliable and efficient operation.

Industry Challenges This Solves

Industries such as textile, ink, coating, and F&B often struggle with colour that does not biodegrade easily, even after biological treatment.

Chemical compounds like surfactants, solvents, tannins, and aromatic organics are difficult to remove biologically. These contribute to high residual COD.

Sludge handling areas, drains, and equalisation tanks often produce odour due to anaerobic conditions and decomposing organics.

Chlorine-based systems form harmful by-products (THMs, chloramines), require storage of hazardous chemicals, and are less effective against resistant microbes.

Industries are now expected to adopt greener oxidation processes with lower environmental impact. Ozone offers a clean, powerful, and safe solution to these common industrial challenges.

What Ozone Generator Systems Do

Ozone is generated on-site using electrical discharge technology. The ozone gas is then injected into water or air where it rapidly reacts with pollutants.


Ozone Oxidises:

  • Dyes
  • Pigments
  • Aromatic compounds
  • VOCs
  • Odour-causing molecules
  • Microorganisms and pathogens

This makes ozone a highly effective polishing step.


In simple terms: Ozone breaks down difficult contaminants that biological and chemical systems cannot fully remove.

How an Ozone System Works Step by Step

Black checkmark inside a circle icon on a white background

1. Ozone Generation

Air or oxygen is passed through an ozone generator where high-voltage discharge converts O₂ into O₃.

2. Injection Into Water or Air

Ozone is diffused into a contact tank using a venturi or fine-bubble diffuser.

3. Oxidation Reaction

Ozone reacts immediately with contaminants, breaking down colour, COD, and bacteria.

4. Contact Time

Proper retention time ensures complete oxidation.

5. Off-Gas Destruction

Any unused ozone is routed to a destructor where it is safely converted back to oxygen.

6. Polished Effluent Discharge

This well-controlled process ensures consistent performance and operator safety.
