Plate Settler After MBBR

Separating Biomass from Moving-Bed Reactors

MBBR processes shed detached biofilm that must be separated downstream. A plate settler — often with coagulant — provides compact, reliable solids–liquid separation.

Clarified Effluent

Moving Bed Biofilm Reactors (MBBR) grow biomass on suspended carriers. Unlike activated sludge, they do not rely on sludge recycle — but the detached biofilm and other solids leaving the reactor still need separation before discharge or further treatment.

A plate settler is an ideal downstream clarifier for MBBR: compact, robust, and, with a modest coagulant dose, capable of producing a clear effluent from the relatively light biological solids. It handles the variable solids output of biofilm processes well.

The result is a small-footprint biological treatment train suited to both new compact plants and capacity upgrades.

Engineering Considerations

Biomass Separation

Efficiently clarifies detached biofilm and residual solids from the MBBR.

Chemical Enhancement

A small coagulant dose sharpens separation of light biological floc.

Compact Footprint

Combines with MBBR for a very small overall plant footprint.
