Three (3) ORG filters at an ethanol plant.

Many water treatment processes require pre-treatment to remove the larger suspended solids so they can “polish” the water. Orival filters are a natural choice for pre-treatment before MF, UF, NF and RO membrane systems; ozone treatment, UV treatment, chlorination and other disinfection systems; GAC (Carbon Filter), granular media filter and other fine filtration systems; and for industrial waste pre-treatment before discharge to a sanitary sewer.
