In the process of treating waste water, fine biological sludge is constantly produced during the decomposition process at a sewage treatment plant. For a stable decomposition process in the biological treatment phase, the sludge produced in the secondary sedimentation pond, also known as excess sludge, is removed and fed into the digestion tower. Flottweg's OSE decanters thicken the sludge before it enters the digestion tower. Sewage treatment plants benefit from an even feeding of the digestion tower and can thus optimally use the volume of the digestion tower. The Flottweg OSE decanter is specially designed for sludge thickening. ► Highest gas yield through constant feeding of the digestion tower ► Best possible thickening even with changing feed conditions ► Larger sedimentation volume (due to deep pond and steep cone) enables highest power density (10 - 20 percent) with minimum space requirement

A bio scrubber combines physical scrubbers with a biological activation unit. In this process, air polluted with a wide variety of pollutants is cleaned with the aid of a washing liquid which is loaded with microorganisms and biocatalysts (various enzymes) taken from nature. The washing water absorbs the exhaust air and pollutants from the air. Subsequently, added microorganisms oxidise them. These microorganisms use the air pollutants as substrate and nutrient medium and convert them into naturally formed decomposition products such as CO2, water, and biomass. Here, the washing water is continuously regenerated and used in a closedcircuit water treatment system. TYPICAL APPLICATION AREAS These plants are primarily used for watersoluble ingredients of the exhaust air. The usual pollutants that are filtered from the exhaust air with the help of bio scrubbers include aldehydes such as formaldehyde, alcohols, ketones and other hydrocarbon compounds.
