Biofilm Removal Biofilm is a substance that forms readily in water distribution lines, water storage tanks, and any other aqueous environment. A Biofilm forms when bacteria begin to excrete a slimy, sticky substance that allows them to adhere to surfaces. The
The portable steel-reinforced HDPE pump station includes a vertically upright, cylindrical wet well fabricated from steel-reinforced plastic. Pumps are disposed in the wet well. A pipe connected to the pumps extends to the outside of the wet well to allow outflow of water to external systems.

Unitary concrete pumping station for aqueous waste submersible pumping applications
The sewage retention time in the pumping station, is often so extended that, as a result there are already significant physical, chemical and biochemical transformations with oxygen depletion. In addition, in the expansion well there is a rapid change in hydraulic conditions, associated with vigorous evolution of odors (olfactory system stimulants [ 13 ]) to sewarage air.
Details. A pumping station designed by John Rennie for the Kennet and Avon Canal Company and opened in 1813 with mid-late-C19 and C20 modifications. MATERIALS: constructed of ashlar Bath stone with cast-iron machinery including a waterwheel with iron and timber fittings.
