Treatment Technologies

The right technology for every wastewater

We apply biological treatment, chemical treatment and membrane filtration to treat a wide variety of industrial and municipal wastewater.

01

Biological Treatment

Removal of organic load and nutrients using proven biological processes.

  • Aerobic & anaerobic systems
  • Organic & nutrient removal
  • Secondary clarification
02

Chemical Treatment

Physico-chemical treatment for difficult and variable industrial effluents.

  • Coagulation & flocculation
  • Neutralisation & precipitation
  • Clarification & chemical dosing
03

Membrane Filtration

Advanced membrane systems for high-quality, reusable treated water.

  • Ultrafiltration (UF)
  • Reverse osmosis (RO)
  • Recycling-ready treated water

The Treatment Train

What we engineer – from raw effluent to treated water

Process and mechanical engineering across every stage of a wastewater treatment plant.

1

Screening & Equalisation

Solids removal and flow balancing

2

Primary Treatment

Physico-chemical treatment and clarification

3

Secondary Treatment

Biological treatment of organic load

4

Tertiary Treatment

Filtration and membrane polishing

5

Discharge or Reuse

Treated water meeting the required norms

Our Approach

Assess first, then engineer the right solution

We start with a site assessment, then upgrade your existing system or design a new plant – focused on innovation, sustainability and cost-effective treatment.

01

Assess

Site study of your wastewater characteristics, flows and existing systems.

02

Design or Upgrade

New treatment plants or upgrades to existing systems.

03

Optimise

Cost-effective, efficient design with lower operating costs.

04

Comply

Treated water that meets discharge norms or is ready for reuse.
