Mixed liquor suspended solids (MLSS) is the concentration of suspended solids, in an aeration tank during the activated sludge process, which occurs during the treatment of waste water. The units MLSS is primarily measured in milligram per litre (mg/L), but for activated sludge its mostly measured in gram per litre [g/L] which is equal to ...
The construction of the Katosi Water Treatment Plant is part of a master plan called Kampala Water Lake Victoria Water and Sanitation Project, which was developed in 2011. The project involves improving water supply and improve sanitation services to all of the 2 million inhabitants of the city of Kampala at that time. [9] [10]
Imhoff tank. a - upper chamber, b-c - outlet for sludge, d - outlet for biogas (would need to be higher), f - lower chamber, g - slot for sludge to pass from the upper to the lower chamber, h - height. The Imhoff tank, named for German engineer Karl Imhoff (1876–1965), is a chamber suitable for the reception and processing of sewage.
The RBC process allows the wastewater to come in contact with a biological film in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary (biological) treatment process.
A majority of the water can be reclaimed, and water that is not clean enough goes to the ocean. The West Basin Municipal Water District purchases approximately 37,600 acre-feet (46.4 billion liters), or roughly 9 percent, of Hyperion's secondary effluent for treatment at the Edward C. Little Water Recycling Facility. [citation needed]
Economy favors using small tanks; but if flow rate through the tank is too high, most particles will not have sufficient time to settle, and will be carried with the treated water. Considerable attention is focused on reducing water inlet and outlet velocities to minimize turbulence and promote effective settling throughout available tank volume.
The largest wastewater treatment plants can be defined in several ways. The largest in term of capacity, both during dry and wet-weathers, is the Jean-R.-Marcotte Wastewater Treatment Plant in Montreal. With full secondary treatment of effluents it would be the Deer Island Waste Water Treatment Plant of Boston.
The Biyagama Water Treatment Plant or BWTP is a water treatment facility located at the bank of Kelani River, in Biyagama, Sri Lanka. At a daily output capacity of 160,000,000 L / d (1,900,000 L/ ks ), it is the second largest water treatment facility in the country.
