Activated sludge tank at Beckton sewage treatment plant, UK.The white bubbles are due to the diffused air aeration system. The activated sludge process is a type of biological wastewater treatment process for treating sewage or industrial wastewaters using aeration and a biological floc composed of bacteria and protozoa.
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.
Sewage treatment plant (a type of wastewater treatment plant) in La Crosse, Wisconsin. Wastewater treatment is a process which removes and eliminates contaminants from wastewater. It thus converts it into an effluent that can be returned to the water cycle. Once back in the water cycle, the effluent creates an acceptable impact on the environment.
Sewage treatment plants mix these organisms as activated sludge or circulate water past organisms living on trickling filters or rotating biological contactors. [ 5 ] Aquatic vegetation may provide similar surface habitat for purifying bacteria, protozoa, and rotifers in a pond or marsh setting; although water circulation is often less effective.
Facultative lagoon (polishing pond) providing tertiary treatment after a constructed wetland in Hamburg-Allermöhe, Germany. Overflow from the facultative lagoon may be routed through one or more polishing ponds supporting lower populations of anaerobic micro-organisms and a higher proportion of aerobic organisms adapted to survival in lower concentrations of organic material.
The plant is a complex engineering system of tanks, pipes, specialized equipment and facilities covering the equivalent of 400 football fields. The plant treats wastewater from 80% of the homes, businesses and industry in the area. Once treated, the clean water, known as effluent, is returned back to Lake Ontario.
The capacity was later upgraded to 180,000 kW. The plant is a peaking power plant with two separate generators, generating power for operations and distributing excess power to the local power grid. Water from Whiskeytown Lake is diverted through the Spring Creek Tunnel, a conduit roughly 2.4 miles (3.9 km) long and 18.5 feet (5.6 m) in diameter.
Sewage from the city of Arcata is treated and released to Humboldt Bay via complex flow routing through a number of contiguous ponds, wetlands, and marshes. Resemblance of treatment features to natural bay environments may cause potential ambiguity about where wastewater ceases to be considered partially treated sewage and meets enhancement objectives of the California Bays and Estuaries ...
