Examples of sedimentation tank

• The footnotes to the table say that all the technologies incorporate a primary sedimentation tank and, for biological treatment, an activated sludge process.

• The sludge will become putrescent in a short time once anaerobic bacteria take over, and must be removed from the sedimentation tank before this happens.

• Typically, a trickling filter is followed by a clarifier or sedimentation tank for the separation and removal of the sloughing.

• Phosphate forms precipitates with the metal ions and is removed together with the sludge in the separation unit (sedimentation tank, flotation tank, etc.).

• In 1930, the authorities installed sedimentation tanks which allowed the heavier solids to deposit.

• Early efforts to combat these problems included the use of sedimentation tanks, disinfection by silver ionization and cleaning of the distribution network.

• The third phase was split into two parts, which initially involved the building of new primary sedimentation tanks.

• Once these were operational in 1969, the old sedimentation tanks were converted to become temporary storm sewage tanks.
