Fine Particle Filtration

The TEQUATIC™ PLUS fine particle filter is specifically designed to treat difficult feedwater up to 10,000 mg/L without frequent filter changes, and in the presence of oil. Key benefits include lower cost of ownership via lower maintenance and labor costs, higher uptimes and water recovery, and decreased consumables costs. In addition, the TEQUATIC PLUS filter can help customers reduce the footprint of their operations through, for example, less disposal, minimal handling, and less space along with potential energy efficiencies.
