Abstract
A final clarifier for a sewage treatment plant has a peripheral feed influent channel with lower distribution ports and is also provided with tubes to minimize the headloss in the clarifier. The minimum headloss tubes are set to allow the basin to operate at more than one limiting headloss set point. By increasing the available orifice area at a certain flow rate, a maximum or peak headloss limitation can be achieved without compromising the design (average) headloss.
