Pleated Backwash Filters

N/Ara backwash filters provide removal of contaminants from liquid process streams using fewer filter elements and a compact system. Its crescent-shaped pleat design provides ten times the surface area of standard cylindrical filter cartridges of comparable length and diameter, while still providing the durability to withstand the rigors of automated, high-flow, gas assisted backwashing.

The fixed-pore construction of the filter media allows suspended solids to be collected without the use of a filter aid or additive. The filter's design , with stainless steel core and high tension mesh wrap, maintains its structural integrity through changing influent conditions and repeated backwash cleanings. These filters are available in a wide variety of media and hardware materials and are compatible with acids, caustics and solvents at temperatures up to 160° F (71° C).

These backwash filters are suitable for use with fluids containing a low concentration of solids. Applications include filtration of condensate in nuclear power generation stations, treatment of municipal water and industrial wastewater, brine filtration and filtering of produced water used for oil recovery, clarification of metalworking coolants, and an array of other process applications.
