  • Wastewater Reclamation

    Reclaimed wastewater, sometimes called recycled water, is former wastewater (sewage) that has been treated to remove solids and certain impurities, and then allowed to recharge the aquifer rather than being discharged to surface water. This recharging is often done by using the treated wastewater ...

  • Case study - Daphne utilities water reclamation facility

    With significant TSS and BOD reductions from their Salsnes Filter system, Daphne Utilities has restored previously lost plant capacity. More than that, loading reductions have cut back aerator maintenance and lowered energy consumption of blowers. Project Background Daphne Utilities, situated on the eastern shore of Mobile Bay in Alabama, provides water, sewer and natural ...

  • Monroe Clarifier provides cost-effective expansion of manufacturing capacity via wastewater reclamation and re-use

    Challenge A PVC resin manufacturing plant was looking to expand its operations without purchasing additional water supply, a limiting factor in the expansion decision. In order to do so, the plant had to clarify and re-use the process water that was being discharged from a centrifuge. This wastewater contained PVC fines that had to be removed before the water was suitable for re-use. ...

  • Full-Scale Results from a Biofilm Carrier Process Treating Wastewater from an Ethylene Glycol Reclamation Facility

    The Consolidated Recycling Co., Inc. (CRCI) reclaims between 5 and 6 million gallons of previously used ethylene glycol from spent antifreeze every year. The distillation process generates ethylene glycol contaminated wastewater which must be treated prior to discharge to the municipal wastewater treatment plant. CRCI upgraded the existing facility in 2005 with a biofilm carrier treatment system, ...

  • Full-scale experience with the membrane bioreactor-reverse osmosis water reclamation process

    The Gippsland Water Factory (GWF), owned and operated by Gippsland Water in south eastern Australia, is a 35,000 m3/day water reclamation facility which treats 16,000 m3/day of domestic wastewater and 19,000 m3/day of industrial (pulp and paper) wastewater through parallel membrane-bioreactor (MBR)-based treatment trains prior to discharge to the Pacific Ocean via the Regional ...

  • Reclamation of a mine contaminated soil using biologically reactive organic matrices

    Organic residues such as sewage sludge, biowastes and composts are increasingly used in land rehabilitation because they can improve the physical, chemical and biochemical properties of soil, and reduce the need for inorganic fertilization. Furthermore, their use contributes to an integrated approach to waste management by promoting recycling of nutrients and minimizing final disposal, especially ...

  • Forward osmosis for the treatment of reverse osmosis concentrate from water reclamation: process performance and fouling control

    While high quality water reuse based on dual membrane filtration (membrane filtration or ultrafiltration, followed by reverse osmosis) is expected to be progressively applied, treatment and sustainable management of the produced reverse osmosis concentrate (ROC) are still important issues. Forward osmosis (FO) is a promising technology for maximising water recovery and further dewatering ROC so ...

  • HD Q-PAC® Bio-media Eliminates Odors at Mt. Dora, Florida Water Reclamation Plant. System Very Responsive to H2S Surges

    The water reclamation plant at Mt. Dora, Florida had an odor problem at the headworks collection well. Several pump stations in the community send their water to this location. The discharge of the various lines is random. At times one line may be discharging water while other lines are idle. At other times multiple lines are discharging. There are periods of no water discharge at various times ...

  • Ozone Based WasteWater Treatment

    The Australian Water Association held an international conference on 'Onsite and Decentralized' waste water treatment systems in Benalla, VIC. This was the abstract presented by Kyle Greene, Seair Canada Head of Research and Development. These portable wwtps are used in the extremes of northern Canada oil, gas and mining camps. Featuring: Heavy duty steel container, industrial weather coated, ...


  • Treating wastewater as a resource

    A number of UK landfill operators are turning wastewater into a resource by utilising OTT monitoring and control systems to manage the irrigation of Willow crops (for renewable energy generation) with pre-treated effluent. Background Leachate from landfill sites represents a significant potential environmental liability, extending long into the future after a landfill site has ...

  • The occurrence and fate of chemicals of emerging concern (CECS) in coastal urban rivers receiving discharge of treated municipal wastewater effluent

    To inform future monitoring and assessment of chemicals of emerging concern (CECs) in coastal urban watersheds, the occurrence and fate of more than 60 pharmaceuticals and personal care products (PPCPs), commercial/household chemicals, current use pesticides and hormones were characterized in two effluent‐dominated rivers in southern California, USA. Water samples were collected during two ...

  • Fracking wastewater treatment at collection facility

    Abstract Engineering company operates a wastewater collection and treatment facility for their clients in Myton, Utah. The facility receives fracking and produced wastewater from various pumping stations, and then treats the water for disposal at the injection well located on site. Electrocoagulation followed by two clarifiers and 5 micron filter was used. Since many particles float or just ...

  • Membrane bioreactor technology for decentralised wastewater treatment and reuse

    There is a growing interest in utilising non-traditional water resources by means of water reclamation and water recycling for long term sustainability. Amongst the many treatment alternatives, membrane bioreactors (MBRs) have been seen as an effective technology capable of transforming various types of wastewater into high-quality effluent exceeding most discharge requirements and suitable for a ...

  • How new technologies are shrinking wastewater’s hefty carbon footprint

    Wastewater treatment plants are energy hogs. A 2013 study by the Electric Power Research Institute and Water Research Foundation reported that they consumed about 30 billion kilowatt-hours of electricity per year, or about 0.8 percent of the total electricity used in the United States. Wastewater treatment’s high energy footprint is ironic because the organic matter in wastewater contains ...
