Design and Care of Reverse Osmosis Systems, Part 2: Upstream Equipment

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 [...]

Options for Industrial Water Reuse

Every day in the U.S., more than 355 billion gallons of water are withdrawn from surface and ground water sources to serve industry and the public, according to a 2010 report from the U.S. Geological Survey. As the strain on water sources steadily increases, it is critical for all water users to work towards water conservation. The primary drivers towards water recycling and reuse practices are environmental [...]

Trends in Industrial Wastewater Treatment

U.S. Water’s Technical Manager, Gary Engstrom provided insight into wastewater trends for Flow Control Magazine. The article, written by Matt Migliore, appears below. As the scarcity of water becomes a more pressing issue worldwide, the drive for industry to reclaim and reuse wastewater grows more important. Moreover, industry faces increasingly stringent state and federal requirements regulating [...]

Maximize Asset Protection & Minimize Chemical Costs by Maintaining Your Thermal Energy/Large Chilled Water System

When treating Thermal Energy Systems or Large Chilled Water systems the following standards should be followed to minimize costs to chemically treat these systems and protect the equipment assets. Filtration Use of Biocides Use of Corrosion Inhibitors General Maintenance and Monitoring Filtration  Given the size of these systems the most effective filtration is low micron sand [...]

Benefits of Sidestream & Media Filtration in Cooling Towers

Cooling towers scrub large volumes of air and effectively remove solids consisting of dust, microbiological organisms, and various airborne debris. Make-up water to the tower adds suspended solids in the form of corrosion products, microbiological growths and wood fibers from the tower, and process leaks. If allowed to settle out, these solids can, and do, generate many problems within the system. With heavy solids [...]
