 With a total surface area of 242 ft2, the Horizontal Filtration Trailer (HFT) for temporary water treatment boasts the highest capacity flowrate of any single trailer on the market today. This trailer-mounted system provides high-quality effluent at flowrates up to 1,600 gal/min for general filtration. For pretreating reverse osmosis feedwater, the HFT can produce flows up to 1,200 gal/min. The system can be loaded with filter media, carbon or specialized resin, depending on the application and the customer’s specific requirements.

The Neles RotaryGlobe small-bore control valve can operate cost-effectively at pressures up to ASME 1500 class. Its rotary motion provides superior containment of fugitive emissions, reducing the risk of explosion and injury. The valve is designed so the thrust bearing is not in contact with the process fluid, thus avoiding the corrosion problems that often occur when hard particles are present in the flow.

Advanced Nanofiber Filtration Technology for dust-collection cartridge filters helps reduce emissions by 50% or more over standard cellulose filters, providing a cleaner breathing zone for workers and reducing facility maintenance. It features advanced surface-loading capabilities that result from a mesh of 70–150-nm fibers that trap dust particles on the filter’s surface, where they are easily released during the cleaning cycle.

Updated electrodialysis reversal (EDR) desalination technology removes salt, radium, arsenic, perchlorates and other potentially harmful contaminants from tough-to-treat well and surface waters. Using an electrochemical separation process that allows selective passage of ions in solutions, this EDR system produces high-quality water for a variety of industrial applications, such as cooling tower and boiler make-up water.
