High purity water systems are designed around defined requirements for water quality, flow, pressure, capacity, instrumentation, controls, alarms, materials of construction, and other operating parameters. Validation documentation provides the traceable record that those requirements were actually met. Although validation is …

In high purity water system design, there is no single solution that fits every application. Service Deionization (SDI) and Electrodeionization (EDI) each play a critical role in ion removal, but their effectiveness depends entirely on system design, feedwater quality, and …

In high purity water systems, the storage tank is more than a container. It is the dividing point between two distinct functions: makeup and distribution. These two flows are rarely equal and often operate on very different timelines. Makeup refers …

Deionized water (DI water) is a critical component in various industrial, laboratory, and medical applications due to its high purity and lack of ionic contaminants. However, its lack of ions also creates an ideal environment for micro-organisms, posing significant risks …

Reverse Osmosis is a process for removing dissolved mineral salts, submicron particulate matter, organic molecules and compounds and microorganisms from water by forcing water, under increased pressure, through a semi-permeable membrane. This process is the “reverse” of the natural osmotic …

Deionization is the process of removing ionizable solids from water using the principles of ion exchange. In a water softener, the ion exchange process is relatively simple, and consists essentially of exchanging “softer” sodium minerals/ions for “harder” calcium and magnesium …

Ultraviolet irradiation is a powerful technology that has been employed within pharmaceutical and life science, semiconductor and electronics, food and beverage, and specialty manufacturing industries for several decades. The most common use of ultraviolet radiation is for the disinfection of …

Softening of water by ion exchange process involves the exchange or substitution of sodium minerals/ions for hardness minerals, mainly calcium and magnesium. The exchange is made possible because the minerals are ionic in nature (often called ionized impurities), which means …

Water often contains particles that are incapable of being dissolved in solution. The particles may be comprised of fine sand, silt, clay or other materials. We often refer to these particles as particulate matter, suspended solids and/or turbidity. The size …

Filter & Water Technologies is the only Registered Master Distributor and Service Center for Aquafine / Trojan Technologies, serving the states of NJ, PA and DE. As a Master Distributor, we provide design and sizing of Aquafine’s Ultraviolet Systems to …

Filter & Water Technologies is the Authorized Mid-Atlantic Master Distributor and Service Center for TEKLEEN®. As a Master Distributor, we provide design, sizing, and installation of TEKLEEN’s automatic backwash filters for facilities in a wide variety of industries. Filtration solves …

High purity water system operators frequently inquire about the pH of ultrapure water, a topic that presents unique challenges due to the water’s purity and lack of ion content. What is pH? In aqueous solutions, pH represents the negative logarithm …
