The ISO-DISC disk filter is a continuous filtration system that uses fixed filter disks and a linear backwash system to provide uniform cleaning across the entire filter media area. Key advantages include its ability to isolate and monitor individual disks, having no rotating parts or seals, utilizing all of the filter area, and providing outside-in filtration. It is a compact system suitable for wastewater treatment plants, with performance capable of removing solids down to 10 microns.
