Sewage Treatment

Ultimate Responsive Image Slider Plugin Powered By Weblizar

Treatment of sewage is a prime concern in most establishments. We offer solutions with compact & high efficiency systems for clients with space restrictions. These are optimized to minimize sludge bulking risks (caused by filamentous organisms), which can be seen in most conventional compact systems.

Further, we meet stringent client-specific water quality parameters with membrane technology coupled activated sludge or hybrid systems which leads to higher energy efficiency and lower operating cost.

Our systems can be conventional direct aerobic, anaerobic cum aerobic, MBBR, MBR, or hybrid versions depending on our clients’ requirements.

We treat sewage for;

  • Hotels
  • Apartment complexes & Housing Schemes
  • Factories
  • Hospitals
  • Office complexes
  • Public buildings or any other establishment

We offer Biological Systems with Tertiary Treatments for applications where treated water is to be reused for toilet flushing, gardening and even process use if needed.

Due to recognition in providing sewage treatment plants in Sri Lanka, we are now one of the leading providers of Sewage Treatment Plants in the Maldives.
