METHOD TO PROVIDE AN OPTIMIZED ORGANIC LOAD TO A DOWNSTREAM-WASTEWATER TREATMENT PROCESS

摘要

A method for providing an optimized organic load to a downstream wastewater treatment process includes the steps of: providing a primary wastewater treatment plant including an organic harvester (OH) with an OH effluent output stream with temporal variation in organic content, a sludge filtrate outflow from the primary wastewater treatment plant, a valve controlled by a controller, and a sensor communicatively coupled to the controller, the sensor disposed downstream of a combined outflow line to measure an organic content of a combined outflow to the downstream wastewater treatment process; sensing the organic content of the combined outflow to the downstream wastewater treatment process; adjusting the valve controlled by the controller to maintain about a setpoint organic content concentration of the combined outflow to the downstream wastewater treatment process by supplementing the OH effluent output stream with organically rich matter from the sludge filtrate outflow.
