The Water Research Center (WRC) is a research facility established in 2012 at Georgia Power’s Plant Bowen. The WRC facilitates the development and demonstration of water treatment and conservation technologies.
Livestock production and food processing are two of the many industries that continue to be scrutinized by environmental groups and consumers. Both industries come under fire for their use of resources (energy, water) and production of waste materials. An anaerobic digester that captures biogas combined with a process for utilizing the biogas can help on both fronts.
This increasingly popular approach allows livestock producers and food processing facilities to recycle discarded organics into energy and useful byproducts such as compost, fertilizer, and livestock bedding.

Packaged ultrafiltration membrane systems like WesTech’s AltaPac™ system are more flexible and accommodating of a site’s specific needs than one might think upon hearing the term “packaged.”
One particular East Coast site learned this first-hand, when they came to WesTech looking for a solution for treating a surface water source. The manufacturing company that owned the site wanted to use the water for cleaning their industrial process equipment, as well as pre-treating a portion of the water for a reverse osmosis unit.

In a corporate-academic partnership unique to algal research, WesTech Engineering, Inc. and Utah State University’s Sustainable Waste-to-Bioproducts Engineering Center (SWBEC) are developing processes for more efﬁcient harvesting of algae from municipal wastewater and other nutrient-rich sources. Floyd Grifﬁths of WesTech Engineering, Inc. reports on joint research efforts for converting algae into high-value bioproducts.
Corporations frequently establish joint research partnerships with universities in diverse ﬁelds; however, such collaboration seldom occurs in algal research, which has almost exclusively remained within the province of universities.
Mine tailings disposal, and its impact on water usage, is an important concern for any mining company. The challenge today, whether extracting aluminum, zinc, gold or iron ore, is how to dispose of tailings material such that it is contained and stable, while maximizing water reuse and minimizing surface footprint.
Paste, or thickened tailings, has become an increasingly important method to address many of the environmental problems facing the mining industry. Pasting was originally developed by the alumina industry in the 1970s, and for the past 20 years has been applied worldwide.

Paste, or thickened tailings, have become an increasingly important method to address many of the environmental problems facing the mining industry. The term “paste” as used in this discussion applies to the full range of non-settling tailings that exhibit a yield stress such as “thickened tailings” and “mine paste backfill.”

Acid mine/rock drainage is a rampant problem in the world today. The above photo depicts acid drainage at an abandoned mine in the Yukon Territory of northwest Canada. This mine shares a similar history to thousands of other mines throughout the world. It was in operation for six short years in the 1950’s, producing gold ore. Its profitability eventually failed and it was abandoned. In the years following, the mine changed ownership several times, making it very difficult for the government to enforce treatment for the acid rock drainage that the mine created.
