Process Know-How

Customised Design for Each Project:

• The constituents in the wastewater can be removed using physical, chemical and/or biological means.
• Each method could be designed in a variety of combinations, across the different stages of the treatment process:
  1. Primary Treatment
     • All aspects of physical treatment processes including screening, oil separation, sedimentation and Dissolved Air Flotation.
     • Chemical treatment processes including coagulation/flocculation, precipitation and oxidation/reduction.
  2. Secondary Treatment
     • Removal of biodegradable organic compounds through an aerobic treatment tank coupled with fine bubble diffusers for energy savings.
  3. Tertiary Treatment
     • Tertiary treatment and polishing processes which include further clarification, chlorination, Ozone treatment, UV light disinfection, activated carbon adsorption, filtration and/or Reverse Osmosis (RO).
  4. Sludge Management
     • Sludge thickening and dewatering by drum thickener, belt press, filter press, screw press and/or decanter centrifuge.
     • Extended aeration activated sludge process.
• Objective: To achieve an efficient and reliable system in producing consistently high-quality effluent.
