Hi Peter, A few years back ...

Hi Peter,

A few years back we bid a project in Uganda to do this and it was an upgrade from earthen ponds to containerized MBBR plants.  The project didn't go forward at that time and it did require investment.  I think people might give more specific answers if you posted flow rates and typical effluent quality that you see, to know whether or not things like a drum filter would make sense or not.  Lining the earthen ponds with a geomembrane (HDPE) liner, after installing gas release system underneath with floating laterals and diffusers hanging from them could also improve your treatment quality if it's not already aerobic.  I have former colleagues who could help you look into this further if you are interested.
