Tailor-made solutions from FUCHS
System solutions beyond aeration
FUCHS aerators, mixers and agitators are known for exceptional quality and durability. In addition to these specialised components, FUCHS has also been offering various high-quality system solutions for wastewater treatment and sludge treatment for over 40 years. These include, among others, the neutralisation of alkaline wastewater, the treatment of stormwater retention basins and fixed-bed systems for carbon removal and nitrification.
Neutralisation of Alkaline Wastewater
Many industries generate alkaline wastewater that must be neutralised before being discharged into a biological treatment plant or the sewer system.
Examples:
Wastewater from the textile industry
Wastewater from laundries
Wastewater from calcium silicate brick plants
Neutralisation with carbon dioxide from flue gas is an environmentally friendly and cost-effective process. In many industrial plants, the required flue gas is available free of charge from the company's own heating systems or power plants.
The FUCHS Centrox aerator was developed specifically for this application, allowing flue gas to be introduced directly into the alkaline wastewater as fine bubbles without the need for an additional blower.

Treatment of Stormwater Retention Basins
Stormwater retention basins or overflow basins store additional wastewater that accumulates during heavy rainfall. The settleable substances contained in it accumulate as sludge on the basin floor. To prevent shock loads on downstream treatment plants, the wastewater must be circulated in order to resuspend and evenly discharge the deposited organic solids.
The FUCHS TurboStar® submersible mixer is used in stormwater retention basins to resuspend settled solids and for circulation and mixing. It is simple in design, extremely robust and, thanks to the special shape of the propeller, particularly resistant to clogging. Other applications for FUCHS submersible mixers include buffer tanks, batch-operated thickeners and smaller sludge silos.
Fixed-Bed Systems
FUCHS fixed-bed systems with fully submerged and aerated fixed beds are powerful and cost-effective systems for biological wastewater treatment. They are used as a fully biological treatment stage with or without nitrogen oxidation, as a nitrification stage within a multi-stage process, or as a downstream stage for residual nitrification. They are suitable both for new plants and for retrofitting existing treatment plants. Particular advantages are evident when combined with wastewater lagoons.
