Two AquaDisk Cloth Media Filters Replace Six Granular Media Units, Boosting Capacity 540% And Cutting Backwash Volume By 97%

The Portland, Indiana, Wastewater Treatment Plant (WWTP) had been using six granular-media filter units for tertiary treatment since the 1980s. The plant’s treatment protocol includes fine screens for grit removal, followed by primary clarifiers, trickling filters, aeration basins, secondary clarifiers, the tertiary treatment system, and then chlorine disinfection.

    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.

  • Denitrification/Filtration Technology Helps Wastewater Treatment Plant Meet China’s Stringent Class IA Standards For more than 20 years, the Denite technology has been used throughout the world for denitrification in secondary, tertiary and advanced wastewater treatment applications.

    Cutting-Edge Solutions For Coking Wastewater Reuse To Meet The Standard Of Circulation Cooling Systems

    Coking wastewater generated from the processes of coking, coke gas purification, and recovery of coking products, is highly toxic and carcinogenic. The wastewater usually contains phenolic, aromatic, heterocyclic, and polycyclic organics, and some inorganics, such as cyanides, sulfides, ammonium, ammonia, and so on, which makes it hardly degradable.

    Optimizing Air Flows To Aeration Basins

    As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.
