AQUADECANT AD is a floating decanter that discharges clean water without disturbing the sludge blanket or floatable materials on the surface.

Gravity and pump options are available with mechanical actuation to close the weir during aeration and mixing phases preventing wastewater or activated sludge entering the discharge pipe. There are four options to choose from.

Gravity discharge

AD GRAVITY floating weir + permanently open + gravity discharge
AD-MC/GRAVITY floating weir + mechanically closing + gravity discharge

Pump discharge

AD PUMP floating weir + permanently open + pump discharge
AD-MC/PUMP floating weir + mechanically closing + pump discharge
