Virtually all water purification applications, ranging from boiler feed to semiconductor and pharmaceutical manufacturing, use at least one membrane separation technology. With the growing trend towards water recovery and reuse, here are some technologies that will play an integral role in these applications in the future.

Large diameter reverse osmosis (RO) membrane elements were originally designed as a cost-saving solution for very large plants producing ten million gallons (1,600-m3/h) of water or more per day. However, market acceptance of 18-in diameter RO element shows that large diameter elements are also efficient and economical solutions for brackish water RO systems with a capacity beginning at 400,000-gpd (60-m3/h), and for seawater desalination systems producing as little as 100,000-gpd (16-m3/h).

Compared to conventional biological wastewater treatment systems, submerged membrane bioreactors (MBR) produce significantly improved effluent quality and have a substantially smaller footprint. Throughout the past decade, MBR systems have been installed in thousands of municipal and industrial wastewater treatment plants for challenging wastewater applications for plants including paper mills, breweries, food processors, chemical plants and textile manufacturers.

The scarcity of water resources directly and indirectly impedes economic development in China. The lack of potable water directly impairs the health and well-being of millions of people and restricts agricultural and industrial activity. The shortage of water also causes a secondary problem by constraining the ability to expand electrical power production to meet the needs of the rapidly growing economy.
