US demand for membrane materials will rise 8 percent per year through 2014. Nonpolymeric membranes will outpace the dominant polymeric segment. Ultrafiltration and reverse osmosis types will be the fastest growing. Chemical processing and pharmaceutical/medical markets will offer the best opportunities.This study analyzes the $3.3 billion US membrane industry. It presents historical demand data for the years 1999, 2004 and 2009, and forecasts for 2014 and 2019 by type (e.g., cellulosic, polysulfone and nylon, ceramic), application (e.g., microfiltration, reverse osmosis, ultrafiltration, pervaporation) and market (e.g., water and wastewater treatment, food and beverage processing, pharmaceuticals and medical uses).The study also considers market environment factors, details industry structure, evaluates company market share and profiles 37 industry players, including Pall, General Electric and Millipore.
