Water softener resin is extremely porous, which is beneficial because it allows for more surface area to capture calcium and other metals in source water. Surprisingly, 99% of ion exchange actually happens in the interior of the bead. Resin beads, ranging in size from 16 to 50 mesh, are abused daily during the backwash process and by contaminants in the source water. Resin could last much longer in these hostile environments with a few fairly inexpensive solutions.
Cleaning options to reduce resin fouling
The company's Electromedia I and V filtration media are now compliant to NSF/ANSI Standard 61
Filtronics Inc.’s Electromedia I and Electromedia V filtration media now carry certification by NSF Intl. to be compliant to NSF/ANSI Standard 61 for contact with water. The review process included an inspection of Filtronics’ manufacturing facility in Anaheim, Calif., and testing of the media materials to ensure the safe use of these filter media in the treatment of drinking water.
Patented KDF 55 process medium provides a highly effective means of removing contaminants in water in POE or POU applications, removing up to 99% of heavy metals from filtered water. KDF 55 medium is a high-purity formulation of copper-zinc alloy that reduces contaminants such as chlorine, bacteria and heavy metals using a chemical process called redox, or oxidation-reduction.
When the McGraw Hill Data Center in East Windsor, N.J., was being built, the local municipal authority informed the company that it did not have the capacity to support the makeup water for the data center’s condensers or chill water plant. A new well was drilled to serve the plant; however, the groundwater supply had iron and manganese levels that exceeded regulatory limits.
System resolves high contaminant concentrations for data center
KDF has a new brochure available featuring the company’s different forms of process media for a variety of applications in water treatment. These media can be used alone or in conjunction with filtration, RO and existing water treatment technologies.
India is regarded as one of the fastest growing global markets. With an official Indian government growth forecast of 8.75% in 2011, the country emerged relatively unscathed from the recent global economic downturn.
India occupies only 2.4% of the world’s landmass, but it has more than 15% of the world’s population, with a median age of 25. Approximately 70% of India’s population lives in more than 550,000 villages; the rest of the population lives in more than 200 towns and cities.
New filter provides low-pressure solution
Arsenic and its compounds have been known to be toxic for millennia. Arsenic trioxide (As2O3), often referred to as white arsenic, was a favored poison in the Middle Ages because it had little odor or taste, enabling it to be easily incorporated into the food or drink of a victim. As little as 300 mg can be fatal to an average person.
Solutions to an age-old threat
Enpress LLC has expanded its Vortech product line—a new and innovative bottom distribution system for all filtration and softening media. The feature is now available in all 7-, 8-, 9-, 10-, 12-, 13- and 14-in. diameter vessels. The company has also expanded the Vortech to use with 1.050-in., 32-mm and 1.315-in. distributor tubes. The Vortech reduces system backwash rates by more than 30%, due to improved bed lift and mixing at lower flow rates. This system has improved softening capacities, pressure-drop characteristics and the reduction or elimination of under-bedding and channeling.
The NSF drinking water treatment unit testing and certification program includes standards to address the wide variety of point-of-use (POU) and point-of-entry (POE) drinking water treatment technologies on the market today, with more than 3,000 systems and 2,000 components currently certified under seven NSF/ANSI standards. These seven technology-specific standards are listed in Table 1.
