Capture, clean, expel: how Ronningen-Petter systems from Eaton work
Every process is unique - that’s why we offer several backwashing/tubular systems in several configurations.

The only multi-element, single-housing filter in the backwashing/tubular family, the VWS-Series offers high-flow capability and is well-suited to code applications. Filter elements are arranged in a circular pattern within a single large housing. At the center of the system is a rotating washing arm. When an elementmore

Cake Formation Increases Operational Efficiency

N/A While the filtration media provides some of the filtration action, collected contaminants actually further increase efficiency. We call this phenomenon "cake formation." The collected solids (or "cake") trap additional contaminants. The key to making this principle work is timely cleaning - too soon and you lose the benefit, too late and the system flow becomes hindered.

Ronningen-Petter systems come factory pre-set to backwash when the differential pressure from inlet to outlet reaches 15 psi (1 bar) - typically the optimum time to initiate backwashing, although this is adjustable.
