Filtering Through The Latest In Primary Wastewater Treatment
2/16/2017
Of course, the whole wastewater treatment equation starts with primary treatment. Although a critical first step in the process, primary treatment rarely receives as much attention from innovators as processes further down the line. It’s about time that changed.

Aerobic Granular Biomass Technology: Recent Performance Data, Lessons Learnt And Retrofitting Conventional Treatment Infrastructure
2/10/2017
Aerobic granular sludge has been extensively researched over the last two decades as a part of the search for more sustainable wastewater treatment solutions. Conventional activated sludge (CAS) systems have key disadvantages such as slow settling flocculent biomass necessitating large clarifiers and low reactor biomass concentrations (typically 3-5 kgMLSS/m3), large treatment system footprints and relatively high system energy usage. It has been shown at the lab, pilot and the full scale that aerobic granular sludge has distinct advantages, when compared to CAS systems, including improved settling characteristics, which in turn allows for higher biomass concentrations and hence more compact treatment systems.

Two AquaDisk Cloth Media Filters Replace Six Granular Media Units, Boosting Capacity 540% And Cutting Backwash Volume By 97%
8/14/2014
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.

Oldest Town In West Virginia Adopts Modern Wastewater Treatment System
3/6/2014
As with many of today’s aging plants reaching 30+ years of service, the outdated technology and in-efficiencies had placed a burden on a West Virginia town and its officials. The system was no longer able to accommodate the community’s growth or meet the effluent requirements on nitrogen and phosphorus.
