Decentralized Sewage Manila, Philippines - Case Study

Situation
A large urban water authority in the Philippines wanted to reduce power consumption and treat sewage for environmentally friendly discharge to nearby water ways.

Solution
Four BioGill bioreactors were retrofitted to the existing decentralized Sewage Treatment Plant (STP).

Design
The modified process saw the aeration tanks removed, retaining the balance tank and the clarifiers (which served an additional purpose as the treatment tank). A screen was added between the balance tank and the clarifier to remove large particles.

Results
This process treated approximately 45kL/d with 89% reduction in BOD with treated effluent typically recording <15mg/L. As oxygen is freely available in the above ground BioGills, expensive aeration was not required, leading to reductions in energy consumption of up to 80%. This equates to monthly energy savings of approximately US$1,473 and a yearly saving of US$17,672.
