Method and system for improved biological nitrification of wastewater at low temperature

摘要: The present invention entails a method and system for enhancing biological nitrification in wastewater treatment process. process both mainstream sidestream wherein the produces an abundant supply of supplemental nitrifiers that are turn directed into assisting carrying out mainstream. Specifically, includes directing liquid stream (such as dewatering liquid) having high ammonia concentration at elevated temperature zone which is operated conditions maximize production therein. Afterwards, resulting produced where function to enhance allows operation low sludge retention time otherwise could not be sustained.
