Membrane systems have gained wide favor for their ability to produce high-quality drinking water while providing a physical barrier to pathogens, including parasitic cysts.Among the more recent introductions in this category is the TARGA II hollow fiber water treatment system from Koch Membrane Systems. These units are designed to provide compact, cost-effective treatment in municipal drinking water systems and in other applications including desalination pretreatment and industrial water treatment.The membrane fibers themselves use polyethersulfone (PES) chemistry in place of the polysulfone used in the product’s previous generation. This ultrafiltration technology uses an “inside-to-outside” flow path. Kevin Phillips, product manager, described
