S::Select - Activated Sludge Systems

The settling of the activated sludge and thus the sedimentation rate is the central design and operating parameter for the activated sludge. S::Select ® accelerates the sedimentation of the sludge and drastically relieves the burden in the secondary clarification. Bulking sludge no longer occurs and sludge thickening is significantly improved. Further effects of the more compact sludge are a denser flake filter, which noticeably reduces the solids in the secondary clarification process.

Essde - Deammonification Systems

The EssDe process stands for efficient nitrogen elimination using deammonification . What follows is a maximum abbreviation of conventional nitrification and denitrification . Only half of ammonium is oxidized to nitrite . The remaining ammonium and the nitrite formed are then reduced to elemental nitrogen with the help of specialized bacteria called planctomycetes .

EssDe - Sewage Treatment Plants

Most of the aeration energy in a sewage treatment plant is required for nitrogen oxidation (nitrification). The subsequent denitrification requires carbon, which would be more advantageously converted into methane in the digester.
