Most water used in pharmaceutical and biotech plants is treated to meet the standards of the US Pharmacopoeia (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 ad 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 is essential to the safe treatment of patients in any healthcare facility from a doctor's office to a hospital/trauma center. Choosing the right filters helps protect patients.
The instruments used in medical facilities are cleaned between uses and rinsed with filtered or purified water. Treatments from endoscope to traditional surgery require the reprocessing of diagnostic and surgical devices with the reprocessing procedure requiring filtered or more highly treated water. Dialysis patients require water with very specific purity standards set by the USP and AAMI.
The semiconductor industry requires the purest of all waters - what the industry call "ultrapure water." The purity standards are set by the Semiconductor Equipment Manufacturers Institute (SEMI). SEMI has established these standards to assure that the chips used in the device on which you are viewing this web page will work as expected.
Critical Process filtration understands how filters are used in water systems that create and distribute ultrapure water for semiconductor fabrication, storage media manufacturing and flat panel display making.
Water for many industrial and commercial operations is treated with reverse osmosis, deionization, softening or some combination. Filters are used to remove a wide variety of contaminates from particles to bacteria to dissolved organic compounds and chlorine.
The uses of filtered and purified water are many. Water is critical for cleaning food products fro packaging. car washes use reverse osmosis treated water for a spot-free rinse. Coffee shops use filter to remove chlorine and other organic tastes from their water. Restaurants filter the water used for cooking to get consistent flavors. Chemical processors need purified water as a raw ingredient. The list goes one 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.
