MetaSEP CH

The MetaSEP CH Series is a cellulosic fiber cartridge using chelating fibers from Chrest. By adopting cellulose fiber, it is inexpensive and has high retention capacity. It has excellent liquid permeability and is suitable for heavy metal treatment of large volume waste liquids. CH-1 (aminopolycarboxylic acid type) is used for removal of transition metals, and CH-2 (polyhydric alcohol type) is used for removal of boron, arsenic, selenium, and germanium.
