The application of activated carbon to drinking water dates all the way back to 450 B.C., when Phoenician trading ships stored drinking water in charred wooden barrels. This practice was widely in use on long sea voyages by the 18th century. Even today, brewers use charred wooden barrels to remove impurities during the aging process.
Assessing activated carbon requires a rigorous review
The WW Waterwarmer heat exchanger/cartridge filter allows you to heat or cool as you filter, with no need for a separate heat exchanger. Its compact design and dual-purpose features save space, piping and installation time while improving lubrication and cutting performance. Features include a patented up-flow design, an electropolished 304 stainless steel housing and a fail-safe lid closure rated for 150 psi. It comes in three sizes for greater media surface area and thermal output transmittance, and is equipped with Harmsco Premium 801-20-HT Polyester-Plus filter cartridges.
UPC filter cartridges are manufactured from a proprietary blend of 50% carbon and 50% polypropylene fiber yarn. The carbon and polypropylene media are bonded to prevent carbon transfer during handling and downstream carbon fine migration. The filters are offered in various lengths, outside diameters, micron ratings and core materials. They offer the performance and reliability of string-wound cartridges with the advantages of carbon.
Granular activated carbon (GAC) is the great equalizer, providing superb filtration for a wide range of end-user concerns. It is a versatile, high-capacity powerhouse medium that can reduce and capture a multitude of contaminants. Its massive surface area and physical structure allow for contaminant reduction, primarily via adsorption, catalytic reduction and physical filtration.
Considerations for properly configuring a GAC filter system
SW Premium string-wound cartridges for Hurricane and WaterBetter filter housings are fabricated with the latest technology and provide depth filtration, which primarily retains contaminants within the tortuous passage in the depth of the cartridge wall. Cartridges are wound in a precise pattern around the core, providing dual-gradient filtration with greater surface area. They are capable of withstanding temperatures up to 165°F and will accommodate flow rates up to 150 gpm.
Aqua Flo filter cartridges fit most standard 10- and 20-in. housings and are available in 10 different construction types, including string wound, pleated polyester and dual gradient. Aqua Flo housings include the Big Value series, which comes in a variety of sizes with durable reinforced polypropylene construction and a pressure relief button. The housings have stainless steel reinforced threads, a three-position valve in head, and ship with a mounting bracket, hardware and a filter wrench.
The Pro Easy Feeder is a non-electric continuous-feed dispenser designed for use with Res Care Resin Cleaning Solution. This product is made and assembled in the U.S., and includes a cap, bracket and feeding tube. It allows users to simply clean and restore resin beds to peak efficiency and maintain water softener performance.
Wound cartridge filters provide true depth filtration, high dirt-holding capacity and low media migration. They are one-piece cartridges manufactured using a high-speed, continuous wind process and are available in a wide variety of lengths and porosities. Filters are available in an almost endless combination of media and core materials to handle virtually any chemical, environment or temperature.
Pentek and Hydronix cartridge filters and housings offer sediment and taste and odor removal
Water-Right Inc. expanded its product offering with a full line of Pentek and Hydronix cartridge filters and housings. Water-Right stocks and distributes a wide variety for virtually any type of water problem, from contaminant removal to taste and odor reduction.
Sediment removal and taste and odor removal cartridges are available in many different sizes and types including polypropylene and pleated, string wound, dual gradient and pleated filter cartridges. Specialty cartridges are also available for use in specific applications such as heavy iron removal or corrosion control.
Partnership with DEKA R&D will provide water purification systems to rural parts of Latin America and Africa
To further advance the Coca-Cola Co.’s goal to replenish 100% of the water used in its beverages and their production by 2020 and support sustainable communities, the company announced a long-term global clean water partnership with DEKA R&D to bring DEKA President Dean Kamen’s “Slingshot” technology to communities where potable water access is limited. The company and DEKA R&D also will partner with the Inter-American Development Bank (IDB) Group and Africare to bring the technology to communities in need in rural parts of Latin America and Africa, respectively.
