  • After the UASB has removed the bulk of the organic COD, the wastewater requires polishing by aerobic treatment. A two-step process involving activated sludge reactor, followed by a membrane bioreactor has been proposed in order to maintain the smallest possible footprint and achieve the highest possible effluent quality.
  • Aerobic reactors utilize oxygen to facilitate metabolism of organic matter by microorganisms. Furthermore, in this process nitrogen (TKN/Ammonia) is removed by nitrifying and denitrifying bacteria and is released to the atmosphere as harmless N2 gas.
  • The aeration basin will be lined with AEROSTRIP fine bubble diffusers, which have the lowest cost of ownership of any diffuser available on the market. They require 40% less energy than conventional fine bubble diffusers and have a maintenance frequency of between 5 – 10 year intervals.
