  • Class a biosolids production at eastern municipal water district using heat pasteurization

    Since 1998, the Eastern Municipal Water District (District) has developed and successfully operated a heat pasteurization facility to treat extended aeration waste activated sludge (WAS) from the Perris Valley Regional Water Reclamation Facility (PVRWRF). The treatment train uses hot water to sludge spiral heat exchangers and a patented continuous-feed, complete mix pasteurization vessel (heated ...


  • Processing Wastewater Sludge Using Dewatering Containers

    The relative cost of dewatering equipment varies widely and is directly related to the processing rate. For smaller utilities that need to dewater sludge in batches, dewatering containers are an alternative that can be relatively inexpensive and simple when compared to other technologies on the market. The most common type of dewatering container is based on a roll-off box design, although any ...

  • Activated Sludge Treatment Plant - Eatonton, Georgia - Case Study

    Solids management at municipal wastewater treatment plants is crucial in maintaining operating efficiencies and permitted discharge levels. Drying beds and mechanical methods of dewatering bio-solids can be labor intensive and inefficient for rapid solids removal. Miratech Geotube" Dewatering Technology offers munic-ipalities a cost effective solution for rapid solids removal and long term solids ...

  • Wastewater Treatment Plant - Newport, New Hampshire - Case Study

    THE CHALLENGE Newport, New Hampshire is a small New England community of 6000 residents. The treatment plant treats primarily residential sewerage, although Newport is home to an internationally known firearms company, which also sends its waste to the municipal plant for treatment. This 1.3 MGD plant which operates at an average of .75 MGD, was built in 1971 and upgraded in 1988 to ...

  • Remote controlled `Pit Hog™` dredge removing sludge from aeration lagoons at Los Alisos, California, Waste Water Treatment Plant

    The Los Alisos Water District Water Reclamation Plant is removing raw sewage solids, decayed algae and microorganisms, and algae-laden sludge from its aeration lagoons using a Liquid Waste Technology (LWT) remote controlled lagoon dredging system. The tertiary wastewater treatment plant treats four million gallons per day. Officials of the Lake Forest, California facility initiated the buildup ...

  • Wastewater treatment facility uses ‘monsters’ to better manage screening, odor and trash

    As wastewater pours into the Cobourg Water Pollution Control Facility located on the outskirts of this Canadian town, it comes loaded with organics, trash, debris and chemicals. A large perforated plate screen system, called a Monster Separation SystemTM, is the plant’s first line of defense and removes all unwanted solids in order to protect downstream processes.Managers at the facility report ...
