Chemical-Free Degassing Alternative For The Pharmaceutical Industry
When treating water for the production of pharmaceuticals, carbon dioxide content in the raw water must be reduced to obtain purified water with the proper conductivity. Though sodium hydroxide dosing has historically been used to control CO2, membrane degasification technology is an alternative approach that eliminates the need for chemicals. In this tech brief, learn how the OEM Hager + Elsässer uses membrane contactors for efficient gas removal in their pharmaceutical water treatment systems.

City Saves Money And Energy With Real-Time Control System
Because blowers are run continuously, energy costs associated with the aeration basin are typically the largest expense for wastewater facilities. The wastewater treatment plant in the city of Grand Rapids was looking to reduce aeration energy costs and recently upgraded the facility with a Hach Real-Time Control System. The result was a nearly $60,000 energy efficiency incentive payment from Consumers Energy, and the plant is now on track to save the city more than 735,000 kilowatt hours of electricity and $62,000 annually.
Eliminating Sludge Islands In Your Wastewater Lagoon
Old municipal and industrial wastewater lagoons have the tendency to build islands of sludge at various locations around the lagoon. It is most common for older lagoons to build such islands wherever wastewater enters the lagoons. By Jim Dartez
Upgrade To Diffused Aeration Results In Significant Energy Savings
After 35 years of use, the fiberglass jet aeration manifolds in the Western Regional Water Reclamation Plant (Dayton, Ohio) had deteriorated, rendering four of eight wastewater aeration tanks inoperable. Managers recognized an opportunity to utilize a fine bubble diffused aeration system that eliminated the need for the pumps. The result: higher oxygen-transfer efficiency and reduced power costs to operate the system.
Water Scarcity Poses Huge Threat To 11 U.S. Cities
A recent report offers bad news about water scarcity in the U.S. The report from the National Oceanic and Atmospheric Administration (NOAA) "showed that nearly one in 10 watersheds in the U.S. is 'stressed,' with demand for water exceeding natural supply -- a trend that, researchers say, appears likely to become the new normal," according to the Huffington Post.

Pharmaceutical Industry Meets Pure Steam Requirements With Membrane Contactors
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.

Read the case study for full details.
How A Wisconsin Paper Mill Increased Capacity And Improved Water Quality
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.
Deaeration System Eliminates Need For Maintenance And Cuts Cost for Paulaner Brewery
High oxygen levels in beer will cause organoleptic problems in the final product, so breweries aim to achieve oxygen-free water.

Increase Revenue With New Commercial Metering Technology
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.
