When operating cooling towers, solids build up in the recirculated water. Cooling towers effectively scrub large volumes of air, which adds solids consisting of dust, microbiological organisms, and various airborne debris. Tower water can also have suspended solids from the make-up water source (e.g., turbidity), chemical treatment products, microbiological growth, and even wood fibers from the tower itself. As they [...]
Maintenance is vital to the success of treatment plants across all industries. External filter inspection on a regular basis will keep your plant running optimally and promote system longevity. Consistent inspections will catch minor repairs that when fixed in a timely manner, do not become bigger, more expensive repairs and also prevents a full plant shutdown. When inspecting filter exteriors, there a few things you [...]
Corrosion in industrial and commercial water treatment continues to be a major concern as companies strive to reduce costs while maintaining their assets.

As industrial facilities continually look for ways to reduce capital costs and decrease installation timelines associated with water treatment and other systems, the practice of containerizing equipment has become more prevalent. A containerized system offers many benefits of lower costs than comparable field erected buildings, faster timelines and lower field installation requirements. However, once site building [...]
Reverse osmosis (RO) systems offer power plant owners and operators a reliable and well-proven water treatment solution. However, designing and caring for an RO system requires a thorough understanding of a plant’s water supply and the technology’s capabilities. The final article of this three-part series will address RO system operation and maintenance best practices. Section one and two [...]
Graf Creamery, a Midwestern butter and cream production plant, was experiencing issues with the fat and grease build-up in their holding cell retention pond. The fat build-up was restricting their ability to manage the wastewater leaving the plant and the solids had the potential to fill up the ridge and furrow absorption wastewater process. Due to the fat build-up, they were also losing treatment capacity (maximum [...]
Reverse osmosis (RO) systems offer power plant owners and operators a reliable and well-proven water treatment solution. However, designing and caring for an RO system requires a thorough understanding of a plant’s water supply and the technology’s capabilities. The information presented here could help plant engineers design and optimize an RO system to match their needs. The success of a new RO [...]
