Wastewater Treatment

Wastewater is regarded as used water generated from domestic, industrial, commercial, or agricultural activities, surface runoff, or stormwater. The wastewater needs to be properly treated before being discharged into the environment. “Wastewater treatment" is a sequence of processes applied to remove various contaminants from wastewater and convert it into a treated effluent that can be returned to the water cycle with minimum impact on the environment or directly reused.

Some of our main focuses include:

  • Wastewater management using chemical treatments
  • Wastewater management using biological treatments
  • Wastewater management using Effective Microorganisms (EM technology)
  • Rapid Degradation of FOG Discharged from Food Industry Wastewater by Lipolytic Fungi as a Bioaugmentation Application
