Water & Energy Savings Solutions
Chemstar WATER scours the industry for new technologies to bring water & energy savings to its customers. At Chemstar WATER we are OEM-agnostic enabling us to find the best technology to provide the right solution to meet the customers’ requirements.
Because the evaporative cooling systems are designed to evaporate water and eventually concentrate minerals in the water, they directly affect the water consumption and water savings of the plant. One of the ways to optimize evaporative cooling systems is to pretreat the incoming make-up water to remove the minerals, especially the divalent ions. That way the water can be recycled, reused more before it reaches a critical mineral concentration that would otherwise produce scale and corrosion. Although it sounds easy, removing minerals from water is anything but. Historically reverse-osmosis has been a good tool for just that. However, it has lower recovery rates that hinder water retention. In order to overcome the challenge of removing minerals while saving water, Chemstar WATER has jointly developed a new electrodialysis reversal technology, called cross-flow de-ionization, or in short XDI™. With XDI™ we can improve the cycles of concentration of a cooling system significantly reducing the blowdown water amount and achieving significant water savings.
Furthermore, Chemstar WATER can help improve overall water & energy savings and carbon footprints by reducing the use of chemicals utilizing on-site, on-demand, chemical generation systems, such as on-site mixed oxidant generators, hypochlorite generators, and many others. These on-site generation systems are not only environmentally friendly but also significantly safer than hazardous chemicals.
