Benefits of Side Stream & 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. Tower water adds suspended solids in the form of corrosion products, microbiological growths and wood fibers from the tower and process leaks. If allowed to settle, these solids can generate many problems within the system. With heavy solids loading, even the best [...]
