We are supplier and manufacturer of sewage treatment pump in Bangladesh. Sewage pumps are centrifugal pumps, with special design enabling solids to pass without clogging the pump. When the pump is turned on, the motor starts to rotate the impeller, creating the pressure that pushes water into the impeller and goes into the discharge pipe. A pumping station is made up of a large tank, known as a wet well, that acts as the receiver for sewage from a building or a group of buildings. The sewage will then sit in the well until it reaches a predetermined level. The general construction of a sewage treatment plant doesn’t differ too drastically from that of a septic tank. Just as with a septic tank, sewage flows from the property being serviced into the first chamber of the sewage treatment plant. Here, the water sits until grease, oil and scum have floated to the top and solids have settled on the bottom of the tank. Once the process of separation has taken place, the liquid travels into a second chamber which is where sewage treatment plants differ from septic tanks. This chamber is fitted with an air pump that circulates air around the chamber to encourage the growth of aerobic bacteria. This bacteria helps to break down the contaminants in the water, effectively cleaning it. The final stage of a sewage treatment plant is one last settlement tank. This final tank allows the very last solids that may remain to sink to the bottom of the tank before the effluent is discharged into a soak away or watercourse. Once the treatment process has been completed and the wastewater has been treated as thoroughly as possible, it can be discharged into the environment. This is another key area where sewage treatment plants differ from sewage treatment plants. Whereas you must discharge effluent from a septic tank into a soak away for further treatment in the ground, subject to an Environment Agency Consent to Discharge, you can discharge your effluent into local water sources straight from your treatment plant. This is because of the vastly improved effluent quality that the treatment process produces. If you are looking for high quality of sewage treatment pump in Bangladesh contact us today.
