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 [...]

Your Performance Index: The Importance of External Filter Inspections

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 [...]
