  • Upgrading an existing wastewater treatment plant based on an upflow anaerobic packed-bed reactor

    Upgrading a wastewater treatment plant (WWTP) may be necessary to meet the existing effluent quality and/or to meet the stricter future effluent quality requirements and/or to increase its capacity because of population growth or sewerage expansion to serve more areas. Inability to meet the existing effluent quality may result from lack of proper plant operation and maintenance, inadequate plant ...

  • Dewatering with Geotextile Bags - South Gippsland, Australia (Water Treatment) - Case Study

    A simple, cost effective new method of dewatering sludge is now available in Australia, writes Bill Kelly from CRS Industrial Water Treatment. The use of geotextilcs for containment and dewatering came about as a result of a major flood event in Holland in the 1950s. It prompted Dutch marine engineers to seek new methods and materials to build structures for coastal defences. The ...

  • Groundwater reclassification for five corners area

    Ralph Penney, president of Penney Engineering, sent a letter in April to Tisbury town officials and property owners around the Five Corners intersection in Vineyard Haven asking for their support for a change in the way the Massachusetts Department of Environmental Protection (DEP) classifies the area's groundwater. Mr. Penney plans to petition the DEP for a change in the area's designation from ...

  • Plant Profile - Warrenton Wastewater Treatment Plant Sequential Batch Reactor

    The Warrenton (Ore.) Wastewater Treatment Plant is brand new. In fact, it initiated full operation Jan. 2, although the plant has been utilized since June 28, 2006. The sequencing batch reactor (SBR) plant was constructed on top of an existing facultative sewer lagoon site. The site conditions prohibited deep excavations, so the three basins for the SBRs are shallow, at only 12.5 ft (3.8 m), with ...


  • Achieving Stringent Effluent Limits Takes a Lot of Energy!

    Enforcement of increasingly stringent effluent limits, and application of more sophisticated treatment processes for reduction of chemicals of potential concern, increases the energy consumed in municipal wastewater treatment processes. Energy consumption factors (ECFs) have been developed for wastewater treatment plant configurations based on the quantity of electrical energy used per cubic ...

  • Study of dilution, height, and lateral spread of vertical dense jets in marine shallow water

    This study provides information for the design of sea outfalls to dispose of brine from desalination plants into shallow lagoons of the sea. The behavior of vertical dense jets was studied experimentally by discharging cold saline water vertically upward into a tank filled with hot freshwater under stagnant ambient conditions. The minimum return point dilution, μmin, was determined ...
