Sewage Treatment Plants
JDP offers a comprehensive range of sewage treatment plants designed to treat the sewage from developments where access to the main sewer is not possible. From those suitable for the smallest units, through to plants for large commercial, public & industrial buildings. The correct sizing of the plant is crucial to the quality of the water discharged as is the prevention of grease build up inside that plant. See Grease Traps later in this section. Sewage treatment plants operate by providing an environment in which aerobic bacteria are cultured. These bacteria survive by using biological matter in the sewage as a food source. To provide optimum treatment the bacteria need free access to oxygen and immersion in the sewage effluent. The majority of package plant work by providing a fixed medium that the bacteria adhere to, and a means of interfacing this with regular supplies of oxygen and biological material.
