The membrane processing technologies of microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) are widely used to separate suspended and dissolved materials from water solutions in numerous industrial, medical and drinking water applications.
The increasingly broad range of requirements for water quality has motivated the water treatment industry to refine existing techniques, combine methods and explore new water purification technologies including desalination.
The removal of impurities and contamination from water supplies or industrial chemicals is a process existing all over the world to varying degrees of sophistication. Filtration systems vary enormously according to location, the type of purification required and funding available.
An overview of various filtration methods and their applications
Membrane filtration, widely used in chemical and biotechnology processes, is already established as a valuable means of filtering and cleaning wastewater and industrial process water.
This paper summarizes ozonation and by-product formation chemistry as well as ways to control by-product formation.
"In four years, half of San Diego may be filling its glasses with tap water that once ran through its toilets."
A thorough discussion of not only water treatment systems, but also the contaminants they remove.
Increased focus on technologies that meet tighter regulatory requirements and increased public pressure has motivated municipalities to take a serious look at microfiltration (MF) membranes as a viable treatment option. This article is intended to familiarize you with the basics of microfiltration and discuss how it compares to conventional alternatives.
Municipal and industrial sectors are looking to new and innovative technologies to meet the demands of modern day consumers' requirements. One such technology is ultrafiltration.
The application of membrane technology
Faced with upgrading aging facilities, a Florida water utility decided to incorporate reverse osmosis.
