Kleen Ore is an oleophobic and highly porous technology, it has many Nano-Sized pores that remain water-wet in an oil in water environment that allows the creation of a water shield that prevents the adhesion of oil. The oils coalesce and become trapped along with the solids in between the grains. When the flow path between the grains is restricted, Delta P increases, prompting a backwash, then a new filter cycle can begin.
