Raw wastewater enters the Moccasin Bend WasteWater Treatment Plant influent pump station wet well through bar screens. The screens remove large pieces of paper, rags, leaves, plastic bottles and tin cans. After screening, the wastewater is pumped to the grit removal system and more screening.
· Sludge Drying Bed. It is a rectangular pit excavated to the required depth. The beds are filled with gravel and coarse sand as a filter. Open joints underdrain pipes are laid below the gravel layer. The beds are about 15 m x 30m in plan and are surrounded by .
Activated sludge (AS) is a process dealing with the treatment of sewage and industrial wastewaters and developed around . There is a large varity of design, however, in principle all AS consist of three main components: an aeration tank, which serves as bio reactor; a settling tank ("final clarifier") for seperation of AS solids and treated waste water; a return

Treating the sludge to aid in thickening is known as conditioning the sludge,_Once the sludge has been conditioned, it may be dewatered in a lagoon, drying bed, or one of several other devices. Other processes used to dewater sludge include filter presses, belt filter presses, centrifuges, and vacuum filters. These processes result in sludge with a solids content ranging from 30 to 50 %.
Sludge filtration, separation and treatment systems can be custom engineered and integrated into your process to remove solid waste. Choosing the correct sludge filtration or treatment system that is right for you and your process is vital for maximum efficiency and to not add operating ...

Sewage treatment may also be referred to as wastewater treatment. However, the latter is more of a generalized term that can also refer to industrial wastewater. For most cities the sewer system will also carry a proportion of industrial effluent to the sewage treatment plant which has usually received pretreatment at the factories themselves to reduce the pollutant load.
Most blower appliions for wastewater treatment are for conventional activated sludge aeration. The water level is typically constant, and pressure variations are usually less than one psi. There are other appliions, however, that undergo significant variations in water level. These processes present challenges, but they can be accommodated with proper blower system design.
Sludge Conveyor Systems can be outfitted with new Wastewater Treatment Equipment, or they can be retrofitted with your existing equipment. MetChem manufactures many different styles of Sludge Conveyors, including belt conveyor systems, screw auger conveyor systems, trough and scraper style systems. Please contact MetChem for specific engineering details: such as size, length, elevation, .
· Vacuum Filters Since its first introduction in the United States in the mid1920s, thousands of vacuum filters have been installed in municipal wastewater treatment plants for dewatering sludge. In vacuum filtration, a vacuum applied downstream of the media is the driving force on the liquid phase that moves it through the porous media. The medium can be natural or synthetic fiber cloth, woven ...

A sludge treatment reed bed system utilizes the forces of nature to reduce and treat sludge. The only appreciable power consumption is by the pumps used to transport sludge and reject water between the wastewater treatment plant and the sludge treatment reed bed system, and by ejectors in the sludge buffer tanks (Figure 2).

· Wastewater treatment facilities have long had to contend with the challenge of dewatering sludge to minimize waste and achieve overall costefficiency for disposal. Largescale facilities commonly use mechanical filter presses or centrifuges to dewater sludge. This equipment is often too cumbersome and expensive for many smaller facilities, so they rely on sand filter drying beds for sludge ...
· The vacuum rapidly draws water from the sludge. Vacuum beds can dewater sludge to 15 – 30% TS in a matter of hours or sometimes days. The bed is then cleaned out using a skid loader or small backhoe fitted with a frontloading bucket. Some systems using stainless steel or plastic panels, but without a vacuum pump system, are also in operation.

· Sludge, biosolids, and faecal sludge are generated during management of wastewater and the contents of latrines. The direct disposal of untreated sludge is not desirable because it: 1) has odors, 2) is comprised primarily of water which makes transport and disposal expensive, and 3) contains harmful environmental pollutants and pathogens.
