RoClean P903 is a low pH powdered cleaner designed to remove iron, manganese, aluminum, metal-organic complexes, clays and colloidal material from reverse osmosis (RO) membranes. It is fast acting and buffered to resist pH changes during cleaning. Additionally, it contains dispersants and chelating agents that suspend colloidal material and metallic complexes in solution to prevent redepositing. Compared to other marketed metal cleaners, RoClean P903 does not contain any materials that could emit noxious odors.
RoClean P903 has been certified by NSF International under NSF/ANSI Standard 60 for use as an off-line cleaner in drinking water systems.
