1. Pharmaceutical Industry Meets Pure Steam Requirements With Membrane Contactors
   12/11/2013

   Pure steam is a dependable method for sterilizing pharmaceutical product materials such as equipment parts, instruments, and containers. The removal of dissolved gasses is a necessary step in the steam generation process, in order to meet regional pharmacopeia criteria. Membrane contractors offer a method of gas removal that requires lower initial investment and operating costs than double-pass RO with pH adjustment. This tech brief presents the benefits of using membrane contactors to remove non-condensible gasses such as nitrogen, oxygen, and carbon dioxide from steam.

2. Expert Analysis: Do Our Water Systems Make The Grade?
   12/11/2013

   Water Online Radio sits down with water expert G. Tracy Mehan, a principal with the Cadmus Group and former Assistant Administrator for Water at the U.S. EPA, to get an overview of the progress and challenges facing the water and wastewater industry.

3. Continuous Fill SBR Tanks Help WWTP Exceed Effluent Requirements, Generate Additional Revenue
   12/10/2013

   In order to meet the anticipated effluent criteria required by the Pennsylvania DEP, the Newville Borough Water & Sewer Authority determined that its existing wastewater treatment facility needed renovations. By installing two continuous fill SBR tanks, the facility lowered total nitrogen below permit limits, reduced energy costs, and created a new revenue stream (selling unused nutrient allocations). Read the case study for full details.

4. How A Wisconsin Paper Mill Increased Capacity And Improved Water Quality
   12/10/2013

   In late 2012, production capacity issues arose with several of the clay tile filters at the NewPage Biron paper mill in Wisconsin. Process engineers decided to retrofit two of their four existing dual cell filters with an underdrain system and media retainer. This case study details the system and explains how it doubled capacity for the two filters and improved effluent water quality, leading to fewer plant shutdowns due to seal failures within the mill.

5. Deaeration System Eliminates Need For Maintenance And Cuts Cost for Paulaner Brewery
   12/10/2013

   High oxygen levels in beer will cause organoleptic problems in the final product, so breweries aim to achieve oxygen-free water. Since Paulaner Brewery installed a modular, water deaeration system that uses hydrophobic hollow fiber membranes to remove dissolved gasses, the unit has operated maintenance-free. This tech brief outlines the unit’s design, operation, and the resulting reduction of energy consumption costs.

6. Nuclear Power Plant Removes Dissolved Gasses From Feedwater With Membrane Contactors
   12/10/2013

   When engineers at the Kori nuclear power plant in South Korea found that dissolved nitrogen in reactor feed water led to an increased production of carbon 14, a long-term environmental contaminant, they sought a way to minimize its production. Membrane contactors were installed to simultaneously remove both dissolved nitrogen and oxygen from the water.

7. Increase Revenue With New Commercial Metering Technology
   12/6/2013

   Revenue for water utilities is circling the drain. Most commercial water meters can stand up to the high water flow of commercial water customers, but these same meters often have a hard time measuring low water flows and retaining accurate meter reads over time and continuous flow conditions. Grocery stores, for example, do not pay for the scant amount of water used for produce misters because it passes through many commercial water meters without detection. These low flows add up to big dollars and are forcing water utilities to take a hard look at the accuracy of their meter fleet.
