Upheaval and Innovation in Power Plant Wastewater Management
Published by POWER Magazine
Regulatory uncertainty, changing resources, and an industry-wide drive to cut costs and boost flexibility and efficiency are among a growing list of challenges that are prompting new approaches to treat power plant wastewater. Factors that affect the eventual technology or treatment choices made by plant owners are deeply dependent on their distinct suitability to a plant as a solution.
POWER magazine included comments from WesTech engineer Brett Housley in its roundup article of wastewater treatment solutions.
WesTech is leading an initiative to help provide clean drinking water to Haitians who have been hard hit by Hurricane Matthew. Spearheading the effort, WesTech employees funded an initial batch of 130 portable Hydraid® BioSand water filters capable of converting contaminated water into safe drinking water.

New enhanced high-rate treatment and wet-weather headworks facilities at the Springfield Wastewater Treatment Plant significantly increase peak wet-weather flow treatment capacity and decrease untreated overflows.
Acid mine drainage (AMD), produced from coal and mineral mining operations, presents a difficult and costly problem. With the sheer volume of AMD sites and the contaminants associated with them, it has been described as the largest environmental problem facing the U.S. mining industry, according to the Environmental Protection Agency (EPA).
The Northern Village of Île-à-la-Crosse, Saskatchewan, Canada, operates a surface water treatment plant for its drinking water supply. The water source is Lac Île-à-la-Crosse in northern Saskatchewan, with its corresponding cold water temperatures.
When designing the 22.5 mgd Central Water Reclamation Facility in Cantonment, FL, Baskerville-Donovan engineers specified oxidation ditches. The technology was familiar because the 8.2 mgd (design) Bayou Marcus sister facility had a four-stage biological nutrient removal (BNR) system.
Adding pretreatment to an existing water treatment plant can provide significant process advantages when a plant is faced with challenging influent and stringent effluent water quality regulations. Removing excessive suspended solids early in the treatment scheme reduces the solids loading on subsequent processes, effectively sharing the load among all unit processes.
