  • Waste Water Treatment Plants

    In 1980, Los Angeles began exploring alternatives to control the H2S concentration in the digester gas produced at the Hyperion Waste Water Treatment Plant (WWTP), which treats nearly 420 MGD, wastewater generating over 475 tons of raw sludge per day. The digester gas H2S concentration had to be controlled so that the SOx emissions from the on-site combustion of the gas could be kept within ...

  • What Is Zero Liquid Discharge and How Does It Work?

    Not every industrial facility that produces wastewater will require zero liquid discharge (ZLD). It is usually looked to as a last resort because it can be a complex process that requires a high initial investment. If a facility is located on a site that has severe water scarcity issues and/or astronomical discharge fees, it might be ...

  • Industrial membrane processes in the treatment of process waters and liquors

    A review on pulp and paper industrial membrane processes using a variety of modules and processes is presented. Membranes are mostly used today to purify process waters and to recover coating colours. Ultrafiltration using tubular membrane modules or cross-rotational (CR) filtration has been widely applied for the purification of process waters. The reuse of UF membrane permeate has decreased the ...

  • Low energy mixing to optimize anaerobic digestion at the Kitchener WWTP

    The existing Kitchener Wastewater Treatment Plant (WWTP) is a conventional secondary treatment facility, with a rated capacity of 122,745 mVd. The plant is comprised of two separate secondary treatment plants (Plant 1 and Plant 2) served by a common headworks facilities and primary clarifier facilities. Plant 1 was constructed in the early 1960s and Plant 2 was constructed in the mid-1970s. Both ...

  • Scale-up of the MIEX® DOC Process for Full Scale Water Treatment Plants

    The MIEX® DOC Process is a new process developed by Orica Watercare, South Australian Water Corporation and the CSIRO for the removal of dissolved organic carbon (DOC) from drinking water. Results from scale up of the process to a 170m3/day pilot plant have been reported previously (Nguyen, 1997). The process has now been successfully scaled up and trialed on a 1000m3/day pilot plant located at ...

  • Evaluation of control strategies for drinking water treatment plants using a process model

    This research adds a method to evaluate control strategies to the design methodology for drinking water treatment plants. A process model dealing with parameters related to the calcium carbon dioxide equilibrium was set up. Using the process model, the existing control strategy was compared with a new control strategy and the effects of two different sets of input data were studied. It was ...

  • Does your facility need Zero Liquid Discharge Technology?

    If your industrial facility discharges its waste into deep wells, streams, sewers to publicly owned treatment works (POTWs), and/or other waterways, it is likely there are some types of regulations on discharging the waste. With an increasing push toward environmental protection, many industrial facilities and effluent regulators are strengthening strategies to reduce industrial process waste. ...

  • Nanofiltration As a Post-Treatment at a Conventional Water Treatment Plant

    Introduction The Clifton Water District (Colorado) covers roughly 20 square miles stretching east of Grand Junction to Palisade, and extending south from I-70 to the Colorado River. The District has approximately 7,400 service connections serving a population of 30,000. Utilizing the Colorado River as its primary source, the District's Charles A. Strain Water Treatment Plant has a capacity of 12 ...


  • Perfluorinated chemicals (PFCs) in water purification plants (WPPs) with advanced treatment processes

    A series of perfluorinated chemicals (PFCs) surveys were conducted in two water purification plants (WPPs) having ozonation and granular activated carbon (GAC) filtration processes. In each plant, six different processes samples (source water, influent, coagulation-sedimentation effluent, ozonation effluent, GAC filtration effluent, and final tap water) were collected for two times and eight PFCs ...

  • Problematic algae in the sedimentation and filtration process of water treatment plants

    Problematic algae, species that do not settle or are not easily removed by water treatment processes, are common in many water treatment plants (WTPs). We recorded algae in the water that overflowed from sedimentation basins (SBs) to filtration basins of WTPs in South Korea. Diatoms were common and other algae were not discernible in the flocs. Our field observation indicated that long and ...

  • Control-design methodology for drinking-water treatment processes

    The performance of a drinking-water treatment plant is determined by the control of the plant. To design the appropriate control system, a control-design methodology of five design steps is proposed, which takes the treatment process characteristics into account. For each design step, the necessary actions are defined. Using the methodology for the pellet-softening treatment step, a new control ...
