Wastewater from the beverage industry contains organic solids, such as fruit pieces or grains, and debris, such as broken glass, packing materials and labels. We remove such solids with our ROTAMAT® Micro Strainer screw screen that usually includes a perforated plate with 3 mm diameter perforations. The screw screen simultaneously washes, dewaters and compresses the screenings such that they can be incinerated as solid waste.
After intermediate storage for flow and freight equalization, the wastewater is pumped through a ROTAMAT® Rotary Drum Screen. Since this ultra fine screen is made of wire mesh, with a mesh size between 0.1 and 1 mm, even very fine solids are removed. The screened effluent can be discharged into the municipal sewer.
For full-biological treatment we provide a HUBER VRM® Membrane Bio-Reactor. The effluent of this Vacuum Rotation Membrane VRM® Bioreactor can be directly discharged into receiving waters. The permeate effluent is of outstanding quality and does not contain any solids and bacteria, permitting its reuse as process water.
Waste activated sludge, consisting of biomass generated by biological treatment, is concentrated in our ROTAMAT® Disc Thickener. The thickened sludge is then dewatered in our ROTAMAT® Screw Press. The dewatered sludge cake and the screenings are preferable supplied to a biogas plant in order to increase its gas production.
When we implement our solutions, we also provide our well-proven HUBER stainless steel components, e.g. Screw Conveyors, Manhole Covers and Stairways, Platforms and Guardrails.
