2. Rotating biological contactor - Wikipedia

   en.wikipedia.org/wiki/Rotating_biological_contactor

   Oxygen is obtained from the atmosphere as the disks rotate. As the micro-organisms grow, they build up on the media until they are sloughed off due to shear forces provided by the rotating discs in the sewage. Effluent from the RBC is then passed through a clarifier where the sloughed biological solids in suspension settle as a sludge. [6]

3. Sewage sludge treatment - Wikipedia

   en.wikipedia.org/wiki/Sewage_sludge_treatment

   Sewage sludge can be superheated and converted it into pelletized granules that are high in nitrogen and other organic materials. In New York City, for example, several sewage treatment plants have dewatering facilities that use large centrifuges along with the addition of chemicals such as polymer to further remove liquid from the sludge. The ...

4. API oil–water separator - Wikipedia

   en.wikipedia.org/wiki/API_oil–water_separator

   Typically, the oil layer is skimmed off and subsequently re-processed or disposed of, and the bottom sediment layer is removed by a chain and flight scraper (or similar device) and a sludge pump. The water layer is sent to further treatment for additional removal of any residual oil and then to some type of biological treatment unit for removal ...

5. High-density solids pump - Wikipedia

   en.wikipedia.org/wiki/High-density_solids_pump

   Reciprocating pumps include plunger, diaphragm, and piston pumps. The high-density solids pumps which can be used in the widest range of situations are piston (or reciprocating) pumps. They can be realized as single-cylinder or two-cylinder pumps. In the latter case, power is transferred to the material via delivery pistons working in push-pull ...

6. Waste stabilization pond - Wikipedia

   en.wikipedia.org/wiki/Waste_stabilization_pond

   In facultative ponds, sludge removal may be necessary only in intervals around 15 to 25 years. In maturation ponds, sludge accumulation is very low. [6] Sludge removal, also called desludging, may be done in two basic ways: (i) interrupting the operation of the pond for desludging or (ii) keeping the pond in operation while desludging. [6]

7. Dewatering - Wikipedia

   en.wikipedia.org/wiki/Dewatering

   Pumps being used to dewater a spillway at Baldhill Dam. Dewatering / d iː ˈ w ɔː t ər ɪ ŋ / is the removal of water from a location. This may be done by wet classification, centrifugation, filtration, or similar solid-liquid separation processes, such as removal of residual liquid from a filter cake by a filter press as part of various industrial processes.

9. Maceration (sewage) - Wikipedia

   en.wikipedia.org/wiki/Maceration_(sewage)

   Maceration can be achieved by using a chopper pump in the sewage lift station or at the wastewater treatment plant. [ 1 ] When the flush is triggered, wastewater flows into the macerator, and when the water level rises, pressure activates the unit, causing the stainless steel blades to rotate at 3,600 rpm, pulverizing the wastewater into fine ...
