    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:

Pneumatic Dynamic Lifter Relief Valve Pneumatic Dynamic Lifter Relief Valve

The Pneumatic Dynamic Lifter is a very responsive compact wastewater relief valve that can handle high pressures and uses a compressed air cylinder to hold the valve closed. This chamber is fitted with a relief pilot that is normally closed as long as the line pressure is lower than the set point. If pressure rises above the set point, the relief pilot opens, causing the air in the cylinder to vent, which in turn opens the valve. The valve closes drip tight when pressure falls below the set point.
