The microfiltration systems are skid-mounted and factory assembled for easy reassembly and installation. The tubular membranes are designed for very high solids loadings. The KYNAR® membrane is chemically inert. The membrane provides for an absolute barrier to the passage of solids. This results in the removal of most colloids and therefore provides a filtrate that exhibits a very low SDI, making the filtrate a perfect feed for a reverse osmosis unit or other polishing technology.
