ABSTRACT:
An apparatus and method for cleaning and maintaining Biologically Accelerated Treatment ("BAT") support media disposed within a fixed wastewater treatment tank is disclosed. The cleaning apparatus includes a hollow shaft and a perpendicularly placed diffuser having a plurality of orifices, which may also include nozzles. An air blower or a water pump is attached to the hollow shaft. The cleaning apparatus is inserted into a wastewater treatment tank, and either air or water is forced through the orifices or nozzles of the diffuser, respectively. The air or water generates a force that is directed toward the BAT support media to effect cleaning. In one embodiment, a hinge is provided between the shaft and diffuser to enable the diffuser to pivot downward, to a position close to parallel with the hollow shaft, so that the cleaning apparatus can be inserted through multiple risers that provide access to an underground wastewater treatment tank. The force of the air or water exiting the orifices or nozzles, respectively, position the diffuser in a proper cleaning position when the air or water pressure is sufficiently high. An adjustment cord is provided in case the force of the air or water is insufficient to raise the diffuser to an approximately right angle with respect to the hollow shaft. A handle and extension shafts are also contemplated for use with the cleaning apparatus.
