Ultrapure water specifications and analytical measurement capabilities have advanced to meet the exacting needs of microprocessor, semiconductor and other silicon based device manufacturers.

FILMTEC™ SG30-400/34i and SG30LE-440i reverse osmosis elements have been developed to meet the requirements of higher overall rejection, higher rejection of lower molecular weight organic compounds and silica and an accelerated TOC rinse down profile. These high surface area elements allow for system design with fewer elements and a lower applied operating pressure, thus optimizing amortization of capital costs while lowering operating cost.

Both elements now come with the unique iLEC™ interlocking endcaps that reduce system operating costs, reduce the risk of o-ring leaks and the generation of small particles that lead to poor water quality, and eliminate the need for lubricants. See form No. 609-00446 for more information on the benefits of iLEC interlocking endcaps.

SG30-400/34i is intended primarily for polishing use in traditional UPW systems designed for higher pressure operation. It features a 34 mil spacer to lessen the impact of fouling and pressure drop across a vessel, increasing running time between cleaning and enhancing cleaning effectiveness.

SG30LE-440i is intended primarily for polishing use in newer UPW equipment where the benefits of lower capital cost and lower energy consumption add value.

b Refer to Cleaning Guidelines in specification sheet 609-23010.

c Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Since oxidation damage is not covered under warranty, FilmTec recommends removing residual free chlorine by pretreatment prior to membrane exposure.
