Liquid filtration electronics industry

Liquid separations including reverse osmosis, ultra and microfiltration are pressure driven membrane processes. Membranes are broadly applied to effect separations in these areas. They are used in the making of potable water, in filtration and concentration in the food industries, in the electronic industries... 

The range of industrial applications to liquid filtration is very broad. Water purification is one of the most important applications in liquid filtration. The processes of water purification include microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO), depending on the size of the undesired particles/molecules to be removed. Some examples of industrial applications including fuel filters, water filters, carbon filter, and wet/dry filters are being widely used in the production of textile, cosmetics, food and beverage, electronic components, papers, ship builders, and oil and gas wells. 

The critical applications in the electronics industry are the production of ultra-pure water for the washing of semi-conductor material (silicon chips), and the cleaning of the chemical fluids (liquid and gaseous) used in their manufacture. The object of an ultra-pure water plant for semi-conductor manufacture is to produce water as close to the theoretical purity as possible. Users of ultra-pure water should take all steps possible to ensure that the filters selected meet the highest standards of quality and performance. Every fluid that comes into contact with integrated circuit surfaces is a potential sonrce of the contamination that will affect yields. For this reason, filtration of these fluids at the point of use is essential to obtain high yields. All chemicals that contact microcircuits should be filtered to a level of at least 0.2 pm.
