  • Continuous Fill SBR Tanks Help WWTP Exceed Effluent Requirements, Generate Additional Revenue
    Continuous Fill SBR Tanks Help WWTP Exceed Effluent Requirements, Generate Additional Revenue

    In order to meet the anticipated effluent criteria required by the Pennsylvania DEP, the Newville Borough Water & Sewer Authority determined that its existing wastewater treatment facility needed renovations. By installing two continuous fill SBR tanks, the facility lowered total nitrogen below permit limits, reduced energy costs, and created a new revenue stream (selling unused nutrient allocations). Read the case study for full details.

  • Wastewater Pond Uses Floating Wetlands For Nutrient Removal
    Wastewater Pond Uses Floating Wetlands For Nutrient Removal

    A series of artificial floating wetlands, each planted with 70 individual plant plugs, is introduced to a Louisiana correctional facility's oxidation pond to remove nutrients causing discharge compliance issues. The wetland treatment technology is designed around the same principles as a naturally occurring wetland, however by expanding the available underwater surface area, it encourages greater microbial growth spurring on enhanced nutrient removal.

  • WWTP Cuts Power Costs For Oxygen Generation Over 65% By Replacing Cryo Plant With Custom VPSA System
    WWTP Cuts Power Costs For Oxygen Generation Over 65% By Replacing Cryo Plant With Custom VPSA System

    Management at a 21 MGD wastewater treatment plant (WWTP) in Rocky Mount, NC reports saving over 65% of electric power costs for oxygen production by replacing a cryogenic plant with a custom-engineered vacuum pressure swing absorption (VPSA) system. The move was spurred by reduced input and increased power costs for the WWTP’s pure oxygen, biological nutrient removal (BNR)-type activated sludge system.

  • Case Study: Easy Retrofit Removes Explosive Residues In Water
    Case Study: Easy Retrofit Removes Explosive Residues In Water

    In the mining process, explosives are used to extract the metal-rich ore from the underground deposits. Water is continuously circulated through the mine, where it becomes laden with explosives residue. The main form of explosive used for this application is ammonium nitrate (NH4NO3). The typical constituents found in the process water are ammonia (NH3) and nitrate (NO3).
