Abstract

Activation tank for activated sludge sewage treatment enables all the non-decantable matter to be kept within the tank. The matter is prevented from passing into the clarification tank by the frustrocondical or frustro-pyramidal shape of the bottom of the activation tank, with the base facing upward.
