Septic Tanks and Grease Fat Trap Effluent Polishing

One concern brought before our Engineering Department by the Food Processing industry, was that the fat trap and septic tanks were not complying with the discharge standards. The effluent was sent to the sewage network with high levels of both COD and FOD causing sever damages to the sewage system and resulting in the company paying high fines.


Cequesta Water introduces a simple solution:

 GreeNfloat PP DAF, a fully automatic 24/7 solution
