A simple and low-cost test to measure the physical strength of faecal sludge simulants is presented and used in the development of improved desludging pumps in Kampala, Uganda. The technical performance of two variants of the Gulper manual pump have for the first time been quantitatively assessed under controlled conditions. The time taken to prime and the average flow rate in the following 30 seconds are reported for both pumps on two different strengths of faecal sludge, demonstrating a distinct improvement in the redesigned Gulper II. This pump is now undergoing field trials across East Africa with a view to it being marketed and sold to pit-emptying entrepreneurs by Sanitation Solutions Group.
Aeration System Upgrade Increases Flow Capacity and Reclaimed Water Availability
Read the full Case Study:Replacing Brush Rotors with Aire-O2 Tritons® Increases Flow Capacity and Reclaimed Water Availability Overview: In 2012, the Middlebury, Indiana Wastewater Treatment Plant (WWTP) was faced with aging brush rotors and higher loads in their oxidation ditch system. When Mick Reese was hired as Plant Superintendent, the upgrade design was about 90% complete. The full system upgrade included adding an outer ring to the existing oxidation oval, construction of a new clarifier, controls...
Sludge Blanket Level Detection – making new process opportunities possible
Much Pulsar`s Self-Cleaning Viper Sludge Sensor of the demonstrating the effective maintenance-free solution. discussion around the way we deal with sewage sludge – the way it is moved around the process, the bellmouth valves and decant processes, the downstream treatment of the liquors, important issues around TOTEX and discharge Compliance, plus more recently the green energy benefits of on-site power generation – depends in large part on the accurate and reliable measurement of the strata of the...

Improving Winery Lagoon Performance, Sludge Removal & Efficiency - Case Study
Overview A winery in California faced the challenge of optimizing and treating their wastewater pond in a sustainable manner. The winery had brush rotors frequently breaking down, which were very difficult and time consuming to repair. They were seeking a more reliable option. Aeration Industries International provided that solution in more ways than one. Challenge: Crush season is an extremely demanding time for everyone at the winery. This high demand translates directly to the treatment of the wastewater as...
