The U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA) announced a final rule to improve protections for workers exposed to respirable silica dust. The rule will curb lung cancer, silicosis, chronic obstructive pulmonary disease and kidney disease in America’s workers by limiting their exposure to respirable crystalline silica. The rule changes the Permissible Exposure Limits (PEL) from the current levels of 100µg/m3 of air in general industry (250µg/m3 in construction) to 50µg/m3, averaged over an eight-hour shift. In addition, OSHA affirms in the rule the use of X-Ray Diffraction on silver membrane filters as one of two validated methods for detecting and quantifying airborne crystalline silica in the affected workplace environments.
Sterlitech silver membrane filters are an ideal tool to help keep at-risk workplace environments safe and in accord with the Department of Labor’s final ruling. Affected industries include foundries, abrasive blasting operations,

Sterlitech is excited to announce the availability of small spiral wound membrane elements. At about 1.8” diameter and 12” in length, 1812 spiral wound elements are perfect for scaling up from flat sheets or as a more complete test before pilot scaling. 1812 elements are also ideal for small-scale production, feasibility studies, and product or process development. Operable up to 600 psi, Sterlitech offers SS316 Housing, which is a universal design compatible with the 1812 elements commercially available here.
Sterlitech currently offers commercially available 1812 spiral wound membrane elements from GE, Nanostone, Sydner, and TriSep in a wide range of MWCO, membrane material and surface properties. To browse our complete selection of 1812 spiral wound elements or to place an order with us, click here.
