Water Pretreatment and Filtration Services
Protect your systems, reduce costs, and improve performance—starting with your water.
Poor water quality doesn’t just reduce performance—it can lead to a range of expensive and avoidable problems. Without proper water pretreatment and filtration, systems often require increased chemical use to compensate for poor incoming water. Corrosion and scale formation tend to accelerate, compromising system integrity and lowering thermal efficiency. As deposits build up, heat transfer is reduced and energy consumption rises. Over time, blockages and mechanical stress may result in unplanned downtime and costly repairs. These conditions also shorten the lifespan of critical equipment, leading to higher maintenance costs and early asset replacement.
At Tandex, we tailor our water pretreatment and filtration programs specifically for boiler systems to protect your equipment, reduce chemical demand, and support energy-efficient operation. Each program begins with a detailed analysis of your feedwater and boiler configuration, allowing us to develop a practical, site-specific approach to managing scale, fouling, and contaminant load before they affect performance. By addressing common boiler water issues at the source, our water pretreatment and filtration services reduce system strain, improve boiler reliability, and extend the life of your equipment—all while supporting a more stable and cost-effective chemical treatment program. Our mechanical pretreatment solutions for boilers include:
Water Softening
Filtration

Water pretreatment and filtration are just as essential for cooling towers and closed-loop systems as they are for boilers. While these systems may seem low-risk, even treated water can gradually accumulate suspended solids, corrosion by-products, and microbiological growth. Left unchecked, this buildup can cause restricted flow, under-deposit corrosion, increased chemical demand, and premature component failure—issues that silently reduce efficiency and drive up long-term costs.
Our side-stream filtration systems continuously treat a portion of the circulating water—typically between 5–15%—without interrupting operation. By removing fine particulates and biological contaminants, they improve reliability, extend asset life, and reduce the need for excessive chemical dosing in both cooling towers and closed-loop applications
