  1. Monoclor Chloramine Residual Management System Manages Residual For Problematic 5.5 Million Gallon Tank
    9/23/2016

    Eastern Municipal Water District (EMWD) serves about 142,000 customers in Riverside County, CA. The EMWD service area is one of the largest for any water district in arid southern California. On the drinking water side, EMWD manages two water treatment plants and over 15 reservoirs. With 70% of the district’s water coming from the Metropolitan Water District with chloramine disinfection, EMWD has become reliant on chloramine disinfection to manage long transmission lines and longer detention times.

  2. Industry Innovations For Reverse Osmosis Concentrate: A Challenging Liability Becomes A Valued Asset
    9/22/2016

    Unlike dead-head filtration characterized by a single flow in and out, both reverse osmosis (RO) and nanofiltration (NF) technologies are unique in that they produce two effluent streams, a lower TDS (total dissolved solids) permeate and a higher TDS concentrate.

  10. Horse Racetrack Bets On Flygt For Pump Station Design
    9/20/2016

    200-acre Monmouth Park Racetrack in Oceanport, NJ, is supported by a series of barns and other support facilities that house in excess of 500 horses during track operations. In the mid-1990s the New Jersey Sports and Exposition Authority (NJSEA) constructed facilities to collect horse wash water and first flush stormwater runoff for conveyance to the Two Rivers Water Reclamation Authority (TRWRA), a wastewater treatment facility located in Monmouth Beach.
