Enhancing WWTP Nutrient Removal, Without Overblown Costs

For those who appreciate the old maxim about catching more flies with honey, the logic of creating a more favorable biological environment for better biological nutrient removal (BNR) makes perfect sense. Worldwide implementations of flat-sheet membrane aerated biofilm reactor (MABR) technology are doing exactly that — in less space, with less energy, and with lower operating expenditure (OPEX) for aeration and chemical treatment. Here’s how:
