  • Charlottetown WWTP Chooses Improved Sludge Pumps
    The City of Charlottetown on Price Edward Island changes from conventional progressive cavity pumps to progressive cavity pumps with SEEPEX's Smart Conveying Technology to increase productivity and reduce maintenance times.
  • Searching For The Optimum Pump Sump
    a settling tank for sludge and debris which could clog the pumps or the system. Sludge accumulation can also lead to the build-up of harmful gases. So the optimum sump design should be small enough to prevent the settling of sludge yet large enough to avoid obstructing pump operation. To investigate
  • How to Extend the Life of Your Wastewater Pumps
    Wastewater treatment plants use numerous pumps in a variety of types and sizes to move water through the process. Depending on plant configuration, they may pump influent, activated sludge, thickened or digested sludge, biosolids, scum, filtrate, effluent, or reuse water. Each matrix has specific
  • PC Pumps Handle Tough Wastewater Jobs
    . Before the changeover, as its volume steadily increased, the district had begun incurring high pump maintenance costs in two critical areas: polymer injection and pumping sludge into and out of the centrifuges. By installing new progressive cavity (PC) pumps at each key location, the facility has now
  • 55 Seepex Pumps for Handling Sludge in the Largest High-Rate Clarification System (.pdf)
    Most older cities in North America have combined sewer systems and many, like Toledo, have their WWT plants located in an older part of the city, next to a lake or a river. Space in these locations, is always at a premium and it is difficult to find the land needed for any type of large expansion.
