Aquaflow offers you AF-Sed Primary, Secondary and Secondary Thickening Clarifiers for all kinds of Pulp and Paper mill effluents.

Aquaflow's primary, secondary and secondary thickening clarifiers are designed for all kinds of pulp and paper mill effluents. Their reliable and proper function is essential to achieve the desired final effluent quality parameters.

AF-Sed primary clarifiers provide an uniformly high sludge outlet consistency and incorporate a sufficient reserve capacity to handle unexpected fiber spills from the mill.Futhermore, they feature a special torque control to prevent damages to the rake mechanism in case of very viscous sludges.

Available in stainless steel, AF-Sed primary clarifier assures a long service life with low maintenance. We supply them either with center drives or with more economical peripheral drives for larger units.

AF-Sed secondary thickening clarifiers have properties which improve the activated sludge process. A quick return of living biomass to aeration and integral thickening are the key benefits achieved with our secondary thickening clarifiers.The submerged thickening part eliminates also possible odors.
