This process class is intended for all wastewater and industrial wastewater operators.
Nutrient removal from wastewater treatment plants, especially nitrogen, is vital to protect the health of the Chesapeake Bay. As a consequence, the U.S. Environmental Protection Agency has set new nutrient water quality standards for the Bay. This class is designed to review the principles of biologically converting ammonium-N to NO3-N, converting NO3-N to N2 gas, defining and examining traditional process control tests, performing and interpreting each test, and recording results. Class participants' will learn how to apply operational skills for nitrogen removal (or conversion to a less objectionable form) from wastewater, process control techniques for food-to-mass ratio, mean cell residence time, settleability, sludge volume index, oxygen uptake rate, and sludge blanket depth. Other topics include: Nitrogen Forms and Sources, Biological Nitrification and Denitrification Processes, Breakpoint Chlorination, Ion Exchange, Ammonia Stripping, and Biological and Enhanced Phosphorus and Nitrogen Removal Systems (BNR, ENR).
