Automated apparatus and process for the controlled shutdown and start-up for a wastewater treatment system

摘要

An apparatus and method for cleaning and shutting down a part-time wastewater treatment system is disclosed. The wastewater treatment system has a water input to receive an influent flow of wastewater to be treated, a water output to discharge treated clean water effluent, and a water treatment capacity volume. An effluent external tank receives the clean water effluent and has a size greater than or equal to the capacity volume. Influent flow of wastewater is terminated. Clean water effluent is pumped through a fluid pathway from the effluent external tank to the water input. A sufficient volume of clean water effluent is passed through the wastewater treatment system to complete treatment of the wastewater within the wastewater treatment system, purge wastewater from the wastewater treatment system, and fill the wastewater treatment system with clean water effluent. The wastewater treatment system is thus prepared to be shut down.
