A group of 400 native Peruvian Amazonians known as the Maijuna desperately searched for answers to help reduce their high child mortality rate when it became clear that their drinking water was one of the major culprits.
Water filtration system provides Amazon villages with cleaner water
The Tequatic Plus fine particle filter combines continuously cleaning, cross-flow filtration with centrifugal separation. It is designed to handle a range of difficult-to-treat feedwaters consistently and cost-effectively. Applications range from pretreatment for ultrafiltration and RO to filtering produced water for oil and gas. The product can be used as an alternative or a complement to traditional filtration and is currently available in various flow rates, with filter cutoffs from 10 to 55 µ to meet specific customer needs.
ONE cartridge tank filter systems are offered in two configurations and can utilize a variety of large-capacity cartridges, extending replacement cycle times. The EF-835-1 cartridge tank, with top-mount valve including bypass, is suitable for residential and light commercial applications. The EF-835-2 cartridge tank was designed with a 2-in. inlet/outlet connection at the bottom of the tank, making it ideal for commercial and industrial applications.
KDF Fluid Treatment Inc. offers literature featuring its KDF 55 Process Medium, which provides a highly effective means of removing contaminants from water at the point-of-use. The brochure includes charts, graphs and illustrations detailing the effectiveness of the medium as well as color photos depicting some of its numerous applications.
As many as 2,000 people in remote villages lacking public utilities will benefit
The Prem Rawat Foundation (TPRF) has made a grant of $15,000 to provide clean drinking water to an estimated 1,880 students and teachers plus nearby villages through eight schools in remote provinces of Thailand.
The funds went to the Drinking Water for Schoolchildren Project run by Thailand's Betterment of Life Foundation (BoLF) to purchase tanks and filtration systems selected to best meet the needs of each school. Once they are installed, BoLF will maintain these systems indefinitely.
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.
