Vertical Pressure Filter



Roberts offers vertical pressure filters in diameters up to 12 feet (365.7cm). Different from other pressure filters in the industry, Roberts’ pressure filters utilize the low headloss Infinity® Underdrain and the Aries® Managed Air System. These unique features reduce backwash head requirements, improve backwash distribution characteristics, and achieve efficient backwash cycles. These features, along with Roberts’ standard instrumentation and control package, simplify design and minimize startup complications.

Pressure filters have a specific advantage over gravity filters in ground water applications because the filtration system is typically designed to operate on line pressure and no secondary pumping is required between the raw water source and the distribution system. Specifically, pressure filter systems have been developed to focus on common ground water problems like iron, manganese, radium, and hardness. For high iron and manganese applications, Roberts’ pressure filters can be provided with manganese greensand and potassium permanganate feed systems.

Roberts’ pressure filters typically offer lower initial and operating costs than conventional systems, and the package nature of these systems greatly simplifies the design and installation for the engineer and contractor.

Roberts’ on-staff chemical engineers understand the variety of water treatment challenges that confront municipal and industrial users. They are experienced in applying our state-of-the-art pressure filtration capabilities to solve the most challenging water treatment problems, at significant cost savings.

Roberts specializes in large flow, large capacity systems. Standard vertical pressure filters up to 12 feet (365.7cm) in diameter offer an especially cost effective and reliable solution for iron and manganese removal, turbidity reduction, and process water filtration.

Roberts’ pressure filters can be configured for a variety of direct pumping treatment configurations. Consult our engineering staff for cost-saving solutions.
