FILTERS FOR WATER TREATMENT
Purified water is critical to many processes in medical, manufacturing and cleaning operations. The water quality requirements for most medical and industry applications are well known and established by either regulatory or industry standards, but reaching the required quality is more complex than simply installing a filter or using a reverse osmosis or deionization system.
Water for Pharmaceutical/Biopharmaceutical Processes
Most water used in pharmaceutical and biotech plants is treated to meet the standards of the US Pharmacopeia (USP). The water used must meet quality requirements based on intended use. The requirements are described in detail in various "compendia" in USP documents and are known as "compendial waters".
The water most often used in pharmaceutical and biotech operations is Water for Injection (WFI). Purified Water (PW) is also used for many processes, though many plants find it more economical to operate all systems to the WFI standard.

Water in Healthcare
Water is essential to the safe treatment of patients in any healthcare facility from a doctor’s office to a hospital/trauma center. Instruments used in any facility are cleaned between uses and rinsed with purified water. More advanced treatments from endoscopy to traditional surgery require the reprocessing of endoscopes and surgical devices, which requires filtered or more highly treated water. Patients undergoing dialysis require water with very specific purity standards set by the USP and Association for the Advancement of Medical Instrumentation (AAMI).

The semiconductor industry requires the purest of all waters – what the industry calls "ultrapure water". The standard setting organization for the semiconductor industry is Semiconductor Equipment Manufacturers Institute (SEMI). SEMI has established stringent standards for the water that systems must deliver to assure that the computer chips used in the device you are using to view this internet page will work as expected.

Industrial and Commercial Water
Water for many industrial and commercial operations is treated with reverse osmosis, deionization or even just softening. Filters are used to remove a wide variety of contaminants from large particles to bacteria to even dissolved organic compounds and chlorine. The uses of filtered and purified water are almost endless. Water is critical for washing vegetables during processing and packaging. Car washes use reverse osmosis treated water for their spot-free rinse. Coffee shops use filters to remove chlorine and other organic tastes from their brewing water. Restaurants filter the water used for cooking to get consistent flavors. Chemical processors need purified water as a raw ingredient. The list goes on and on.

Fresh water is scarce in some locations. Some areas lack easy access to any water source other than seawater. There are also coastal areas that see salt water intrusion into both surface and groundwater, so all available water is at least brackish.
Removing salt and other dissolved minerals and organics from water is now economical using reverse osmosis and other technologies. Filters are a crucial part of these systems, removing particulates that can interfere with the treatment process and also protecting the quality of the treated water as it is distributed for use.
