Drinking Water Treatment Case Studies and White Papers

  1. Mountain Regional Water District Deploys Next Generation On-Site Hypochlorite And Tank Mixing Technology To Meet Expanding Water Management Needs
    7/16/2018

    The Mountain Regional Water District is a Special Service District of the county that was established by the Summit County Commission in 2000 to regionalize water service by consolidating several public and private water companies.

  2. Meet (Or Beat) EPA Nitrate MCLs With An AdEdge Packaged Nitrate Removal System
    8/22/2012

    When a food processing plant in Lancaster County, PA was forced to supply bottled water to its employees due to high nitrate levels in its raw water, they had no choice but to investigate a nitrate removal solution. In this case study you’ll learn how the plant avoided EPA violations by reducing nitrate contamination levels to below 8 mg/L and simplified continuous monitoring by implementing a new packaged nitrate removal system from AdEdge.

  3. Rapidly Pinpoint Biological Hotspots In Your Distribution System
    12/14/2016

    After reports of Naegleria fowleri amoeba being found in some Louisiana municipalities’ drinking water systems, regulators mandated that free chlorine residual be maintained at a minimum of 0.5 mg/L throughout distribution networks in the state. In September 2014, Thornton, Musso & Bellemin Inc. (Zachary, LA) conducted an extensive sanitary survey in a small municipality to establish baseline numbers and troubleshoot hotspots.

  4. Theoretical Operation Of High-Efficiency Ultraviolet Water Treatment Chamber
    4/16/2014

    The NeoTech Aqua ReFleX™ water purification chambers are the most efficient and compact units available today. They require an order of magnitude less energy and less than 25% of the system volume to achieve the same or better purification result as competing chambers. This is the first in a series of three white papers explaining the benefits of these systems. By J. R. Cooper, Ph.D, NeoTech Aqua Solutions, Inc.

  5. Direct Filtration Of Spring Water
    10/23/2012

    The Franklin Water Treatment Plant, near the Utah/Idaho state border, serves approximately 600 residents. Traditionally, water was drawn from springs and chlorinated.

  6. How To Calculate Backwash Flow Rate Requirements For Iron Filter Systems
    5/10/2017

    While there are various less common types of treatment systems used to remove iron and manganese from groundwater (such as ion exchange and ultra-filtration), most treatment systems use some form of oxidation and filtration to oxidize the clear state of iron to a solid form so the solid particles can then be filtered out.

  7. Using Membrane Contactor Technology To Extend Resin Bed Life
    2/13/2014

    In today’s economic environment when profits are reduced due to rising costs, it is necessary to find ways to save time and money.

  8. UV Disinfection And Ozone Oxidation In Tandem
    6/5/2015

    Located 30 minutes North-East of Montreal, Canada, the City of Terrebonne has the last drinking water intake of the many cities along the Rivière des Milles-Iles.

  9. Degas Separator Selected For Wichita Aquifer Storage And Recovery Project
    4/26/2017

    In the 1990s, the City of Wichita, KS, developed a water supply plan that included creating a sustainable water supply through the year 2050. The key component of the plan is recharging the large aquifer that lies under the region with 100 MGD of water from the Little Arkansas River.

  10. White Paper: High-Efficiency Reverse Osmosis Treats Gray Water For Power Generation
    1/17/2006

    Recycling of gray wastewater as boiler make- up water was the challenge where silica value was typically 85 ppm in this secondary treated wastewater. This paper describes a new design called the High-Efficiency Reverse Osmosis selected for that task, discusses the project technical considerations and highlights the actual performance of the system.
