Iron is one of the Earth’s most plentiful resources, making up at least 5% of its crust. In well water, iron is usually found as ferrous iron, which is in a dissolved state, potentially causing water to appear clear when first drawn from the tap.
Oxidizing filters combat problematic iron contamination
Nearly two centuries after Henry Doulton invented it, the ceramic water filter continues to be manufactured by the millions. It plays a significant role in the provision of clean, safe water throughout the world.
The filter elements are produced using modern manufacturing techniques to provide a hollow, porous ceramic that is fired at temperatures in excess of 1,830°F. They are most often made from diatomite, which in its raw state is a chalky, fine-grained, low-density material.
Ceramic filter technologies remove pathogens and improve water quality
Sweden’s Bluewater water purification brand launched its SuperiorOsmosis water cleaners
Sweden’s Bluewater water purification brand launched its SuperiorOsmosis water cleaners to the residential and professional market in North America. This water purification technology is designed to generate clean water 24 hours a day and when required, using little energy and slashing the water wastage commonly associated with traditional reverse osmosis (RO) systems.
OKO H2O filter water bottles turn water from questionable sources into a safe, drinkable state
NASA-enhanced water filtration technology used by OKO H2O was recognized in the recent publication of the 2013 NASA Spinoff.
Complex systems on board the International Space Station (ISS) collect and recycle moisture using powerful filtration technology. The filters not only supply ISS occupants with drinkable water; they are likely to play a role in future deep space missions as well.
High-quality bag housings and bags are essential to maximizing the performance of a filtration system. Heavy-duty ASME Code bag housings are available in various sizes, materials and with custom features, and are designed for commercial and industrial filter applications.
EF-1500 and EF-6000 commercial-grade drinking water systems can be connected directly to any existing faucet anywhere in the home. The systems filter down to 0.5 µ and remove many substances commonly found in tap water, including lead and chlorine. They are rated at 1,500- and 6,000-gal capacities, respectively, and are available in select U.S. markets only.
Pleated filter cartridges are manufactured in polypropylene or cellulose media. The high-efficiency cartridges provide high surface filtration and comprehensive service life. Pleated media provide particulate removal and low pressure drops. Greater surface area ensures longer service life due to higher flow and particulate-holding capacity. All cartridges feature DOE Plastisol PVC end-caps for maximum sealing capability.
USM Series submicron pleated filters offer efficiencies comparable to membrane filtration, but at low press drop, with high flow rates and high loading capacity. These cartridges work equally well in fresh, brackish or saltwater. They are made using a proprietary electroadsorptive media technology that is capable of removing submicron pathogens and inorganic contaminants though electro-adhesion and ion exchange. These filters are offered in ODs of 2.5 and 4.5 in. and lengths of 5 to 40 in.
WWIF South Africa and the Unlimited Child install Biosand filters in South African preschools
In a two- to three-day effort spearheaded by Ken Lister and Robin Tindall, with support from the local H2O Intl. Durban branch and Cape Town, South Africa-based H2O Intl. SA, several crèches (preschools for the underprivileged) in the KwaZulu Natal area received biosand filters, positively impacting the daily lives of several hundred children.
