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.
A PEP SMF-FG-24 media filter from Process Efficiency Products, Inc., was installed on the remote sump to reduce biocide costs at the dairy.
Filtration is an important part of most water treatment systems. Filters range from simple cartridge systems to large commercial/industrial multi-tank systems, not to mention the large municipal systems that filter drinking water.
As consumer awareness grows in regard to the quality of water consumed every day from the numerous well water systems across America, the process that is gaining the most attention is that of disinfection.
A discussion of filter housings.
Cellulose acetate membranes serve as the under-the-sink choice for a host of reasons.The nation's water systems are increasingly cited for causing illness due to water-borne bacteria and organisms, creating distrust in the quality of our domestic tap water. At the same time, business opportunities for water treatment vendors are thriving due to the increasing demand in purified water.
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.
Bethel Park, Pennsylvania installed two 4MGD traveling bridge filters in 1980. According to Joe Witkowski, who manages the facility, "We had serious media leakage with our old filters. We had continuous backwashing and mechanical problems - they just couldn't handle high flows. Plus, they had serious media leakage problems."
One Hawaiian hotel was able to quickly fix a filter problem that was turning its tropical ponds into a milky and murky mess.
