WASTEWATER TREATMENT

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.

WASTEWATER TREATMENT CASE STUDIES AND WHITE PAPERS

  • Case Study: Vortex Wastewater Pumps Vortex pumps are primary sewerage pumps used to transport are sewerage through the wastewater treatment plant process. Because these pumps are required to handle the raw sewerage including grit and associated storm water runoff debris the abrasion rate is quite high. In this plant the pumps were lasting less than 1 year before severe abrasion caused reduction in tolerances leading to re-circulation. As the sewerage was no longer being efficiently transported to treatment the plants capacity was effectively reduced. Plant was considering replacement after 1 year a t a cost of $8,500.00.

    Hopkins, Minnesota occupies four square miles of space in southcentral Minnesota, and is home to 17,000 residents. The area is also home to seven lift stations, which pump water and wastewater in various parts of the city – all of which operate with different manufacturer’s equipment. By The Gorman-Rupp Company

  • Ozone Demand Testing = Disinfection Project Success
    Ozone Demand Testing = Disinfection Project Success

    Water and wastewater facilities are increasingly looking to ozone disinfection. A strong and indiscriminant oxidant, ozone can effectively address treatment issues with THMs and DBPs in the disinfection process. Ozone disinfection is also a proactive step toward addressing future rules on endocrine disrupting compounds (EDCs) and other trace organics at both water and wastewater plants. While there are many aspects to ozone disinfection system design, the single most important factor in project success is a thorough understanding of your facility’s ozone demand profile. This article provides an outline of the key factors to make your ozone demand test -and ozone project- a success. By Thoram Charanda and Louis LeBrun

  • Case Study: Gorman-Rupp Addresses Concerns For Higher Head, Greater Flow Through Research & Development Increasingly, end users in the construction, industrial and wastewater markets are realizing the need for higher heads or to pump liquids greater distances, over challenging topography. Professional Engineers and municipal designers have previously had little choice but to overextend pump performance limits of conventional self-priming centrifugal trash pumps, potentially shortening the life of the pump and risking safety issues in the process.

  • HYBACS Called On As Cost-Effective, Advanced Wastewater Solution

    The Town of Botleng in Johhannesburg, South Africa was looking for different technologies to construct a new WWTP to treat a flow of 0.93 MGD with future expansion to treat up to 1.87 MGD flow. Due to financial constraints, the town was searching for an cost-effective, but advanced wastewater solution.
