Sewage Treatment Plants
Package Sewage Treatment Plants will process foul sewage in a similar way to Septic Tanks, the main difference being that sewage treatment plants use mechanical components to break down and remove solids from the effluent, resulting in a much cleaner and environmentally friendly discharge.
Foul water and effluent is fed into the primary chamber where solids and liquids are separated before transferring to the aeration chamber. The aeration chamber compresses the liquid and passes it through a diffuser before it enters the final humus chamber. The aeration process promotes good bacteria that encourages the digestion of the organic matter, breaking it down and ultimately purifying it.
By the time the effluent leaves the humus chamber it is typically 95% clean and ready for discharge into a local watercourse, drainage ditch or land drainage field, subject to Environment Agency consent.
