1. The Murky Future Of Global Water Quality 4/27/2015

   Population growth, economic development, and climate change are placing increasing pressure on our planet’s water resources. Many studies, including one conducted by IFPRI and Veolia in 2011, depict a future world with elevated tensions due to growing demand for a limited supply of water.

2. NEOSEP® Membrane Bioreactor System Simplifies 'Fundamental Necessities' Of MBR 1/17/2014

   The NEOSEP® MBR system features Kruger’s uniquely designed K-120C and K-240C flat sheet membrane modules.  The modules offer several innovative design features that enhance ease of installation, operation and maintenance.  This includes an integrated central lifting eye, offering an incredibly well balanced module that makes installation and retrieval a simple and stress-free process.

3. Replacement Of Synthetic Polymer By Bio-Based Flocculant In Drinking Water Treatment Train: Impact On Water Quality And Microbiological Colonization 7/4/2013

   The use of anionic potato starch in clarification was assessed by comparison with polyacrylamide flocculant in order to evaluate its effect on the performances of Actiflo® Turbo combined with Sand Filtration and Actiflo® Turbo combined with Ultrafiltration in terms of water quality and kinetics of biofilm formation.

4. Zero Liquid Waste: A Desalination Solution For Chloride, Sulfate Limits 3/26/2013

   Mining operations and other energy producers face a multitude of clean-water regulations that can seriously impact their businesses. Strict standards governing discharge into waterways can increase costs and inhibit production. Veolia Water Technologies is addressing these issues through advanced treatment processes that allow companies to generate clean water for reuse or environmental discharge with no substantial liquid waste. Called the Zero Liquid Waste (ZLW) approach, the industrial water desalination technology benefits the mining industry, which must contend with stringent new regulatory requirements that limit the discharge of chlorides and sulfates into streams, rivers, lakes and other bodies of water.

5. Trace Organic Compounds: What Goes In Must Come Out 8/31/2012

   Chemically enhanced high rate settling (CEHRS) shows promise in removing harmful compounds such as pharmaceuticals and consumer products from wastewater. By Daniel M. Austria

6. White Paper: Boiler Water Treatment Chemicals, Feed, And Control - Perhaps It Is More Complicated Than We Thought 3/18/2011

   Chemicals used to treat steam boiler systems are applied based upon the demand and mode of reaction of each chemical used. The theoretical versus actual consumption and the ease of control of these chemicals can vary according to many factors specific to each application.

7. Article: Microbiological Control Strategy In Cooling Tower Systems 8/26/2010

   Because evaporative cooling tower systems are open to the atmosphere and sunlight, they are prone to microbiological (MB) activity and the resulting adverse affects. Pathogenic microbes such as Legionella pneumophila can create health concerns. By Dave Christophersen, Vice President/Technical Manager

8. Article: Using Reverse Osmosis For Boiler Pretreatment 8/26/2010

   There are numerous makeup water pretreatment strategies for boiler systems including softeners, dealkalizers, demineralizers, and reverse osmosis. By James McDonald and Dave Christophersen, CWT

9. White Paper: Understanding Differences Of Boiler Feedwater Pretreatment Equipment 8/26/2010

   As a water treatment professional, there are several reasons for understanding the various types of boiler pretreatment equipment. It is helpful to grasp all selection criteria for the type of pretreatment. These factors are used for deciding what new equipment to install or why the existing equipment is appropriate or not appropriate. By Dave Christophersen, Veolia Water Technologies

10. White Paper: Water Reuse Strategies: Steel Industry Case Studies 8/26/2010

    The steel industry has historically presented challenges for effective water treatment because it is a high water user and the applications may involve high heat, critical noncontact cooling, direct contact cooling, high suspended solids waters, oil and grease contamination, and complicated cascading.
