    7/12/2016

    CH2M contacted Toray Membrane USA with an invitation to pilot our pressurized TIPS hollow fiber UF membrane module for the City of Sherman Texas 10 MGD Expansion Project. This document summarizes the findings of this pilot study program.

  2. Chinese Chemical Plant Optimizes Water Treatment By Replacing Double Pass RO With A Single Pass RO And 3M Liqui-Cel Contactor System
    6/1/2016

    Electrodeionization (EDI) is widely used in many industrial water treatment systems throughout the world. In order to maximize the operating stability and life expectancy of an EDI system they were often designed with double pass RO using caustic injection pretreatment.

  3. Municipality Lifts Boil Water Order Using Mobile Membrane Solution
    5/12/2016

    The Wellsboro Municipal Authority’s slow sand filtration drinking water plant began experiencing high turbidity and algae events due to elevated levels in their reservoir.

  4. Ultrafiltration And Reverse Osmosis Testing On Tertiary Effluent From The North City Water Reclamation Plant
    4/22/2016

    Ultrafiltration (UF) membranes have already gained worldwide acceptance in the treatment of drinking water for their removal of chlorine resistant pathogens such as cryptosporidium. Tertiary treatment with UF has been established, although with a lower level of knowledge and number of installations. This paper will discuss the performance of hollow fiber UF/MF membrane modules in treating tertiary effluent, and the subsequent performance of the downstream RO membranes.

  5. Operations And LRV Calculations At Southwest Pipeline Project Drinking Water Treatment Facility
    4/14/2016

    This presentation will discuss the operation of a 4 MGD pressurized two-stage Ultrafiltration (UF) plant over a 14 month period at the Oliver-Mercer-North Dunn (OMND) Drinking Water Treatment Facility, North Dakota.

  6. Simple Treatment Solution For Surface Water Source
    3/4/2016

    A Montana Water District was under an Administrative Order of Compliance by the EPA to install filtration to comply with the Surface Water Treatment Rule (LT2ESWTR) or possibly loose their only water source, the Missouri River.

  7. Drinking Water Plant Replaced 30 Year Old Carbon Steel Piping With PVC
    2/17/2016

    The city of Virovitica in Croatia is located near to the Hungarian border. Its water works company Virkom serves approximately 20.000 people daily with drinking water. In order to assure required European potable water standards, Virkom decided in 2008 to replace the existing old sand filtration units (total flow rate approx. 320 m³/h) by new ones.

  8. Solution For Algae Blooms
    12/17/2015

    Harmsco® Filtration Products is pleased to offer a solution to the ever increasing blue-algae blooms in water sources. A multi-barrier approach is necessary to physically remove intact (algae and cyanobacteria) before they rupture in the treatment process and then remove extracellular cyanobacteria through adsorption.

  9. Baja California, Mexico Addresses Water Scarcity, Partnering With Fluence
    11/12/2015

    When the government of Baja California, Mexico, declared a water emergency for the region of San Quintín in 2014, leaders knew they needed to find a solution to ensure residents a reliable, safe water source.

  10. Two Innovative Technologies Ensure DBP/TOC Regulatory Compliance
    10/15/2015

    The city of Fort Lupton a growing Front Range community located along the South Platte River in Colorado, began operation of a new 5 MGD (18.93 MLD) membrane filtration system in 1997.
