  2. Decentralized wastewater system - Wikipedia

    en.wikipedia.org/wiki/Decentralized_wastewater...

    Centralized wastewater systems are the most widely applied in well-developed urban environments and the oldest approach to the solution of the problems associated with wastewater. [4] They collect wastewater in large and bulk pipeline networks, also referred as sewerage, which transport it at long distances to one or several treatment plants.

    Bugoloobi Wastewater Treatment Plant (BWTP), also Bugoloobi Sewerage Treatment Plant (BSTP), is a wastewater treatment project in Uganda. It is the largest wastewater treatment plant in the countries of the East African Community , and capable of processing 45,000,000 liters (45,000 m 3 ) of wastewater daily.

  4. Water pollution in India - Wikipedia

    A street in Mathura overflowing with sewage and garbage in 2011. There is a large gap between generation and treatment of domestic waste water in India. The problem is not only that India lacks sufficient treatment capacity but also that the sewage treatment plants that exist do not operate and are not maintained.

  5. Dissolved air flotation - Wikipedia

    en.wikipedia.org/wiki/Dissolved_air_flotation

    Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin.

  6. Reverse osmosis - Wikipedia

    en.wikipedia.org/wiki/Reverse_osmosis

    Sea-water RO (SWRO) desalination requires around 3 kWh/m 3, much higher than those required for other forms of water supply, including RO treatment of wastewater, at 0.1 to 1 kWh/m 3. Up to 50% of the seawater input can be recovered as fresh water, though lower recovery rates may reduce membrane fouling and energy consumption.

  7. Sewage sludge treatment - Wikipedia

    en.wikipedia.org/wiki/Sewage_sludge_treatment

    Sludge treatment in anaerobic digesters at a sewage treatment plant in Cottbus, Germany. Sewage sludge treatment describes the processes used to manage and dispose of sewage sludge produced during sewage treatment. Sludge treatment is focused on reducing sludge weight and volume to reduce transportation and disposal costs, and on reducing ...

  8. Water supply and sanitation in Singapore - Wikipedia

    en.wikipedia.org/wiki/Water_supply_and...

    Until 2010, wastewater in Singapore was collected through a sewer system that included 139 pumping stations that pumped water to six wastewater treatment plants. These pumping stations and plants were gradually decommissioned while a newer system, the Deep Tunnel Sewerage System (DTSS) was made operational. [62]

  9. 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.
