 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

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

The Toray UTC-73U flat sheet membrane is being discontinued by the manufacturer and replaced by the Toray UTC-73UAC membrane.

Sterlitech is launching new flat sheet membranes from TriSep: SBUF and SBNF membranes. SBUF and SBNF are particularly suited for treating surface waters and for the removal of organics and color.
