Existing ASB vs Proposed AST

Benefits of proposed AST system versus Boat Harbour ASB system:

  • increased organic removal efficiency;
  • odour reduction;
    • continuous removal of solids from the primary clarifier does not allow for septic conditions. Septic conditions lead to odour in the existing system because the solids can only be removed after a dry out period in the summer.
  • effluent colour reduction;
    • effluent colour is not increased across an AST as it is with an ASB.
