Today’s emphasis on sustainability, together with more stringent discharge limits, has made producing quality effluent a top priority for treatment plant operators. To achieve these goals, many plants are focused on removing nutrients by lowering nitrogen and phosphorous levels through a range of advanced wastewater technologies.What follows is a look at some processes being used in nutrient removal efforts.1. Moving Bed Biofilm Reactor (MBBR) TechnologyThe MBBR process uses thousands of polyethylene biofilm carriers operating in mixed motion within an aerated wastewater treatment basin. Each biocarrier provides a protected surface area to support the growth of bacteria; the high-density bacteria population,
