HaloSource develops clean technologies to disinfect and purify water
HaloSource Inc., a publicly traded company on the London Stock Exchange, recently joined the growing list of platinum sponsors of Wishing Well Intl. Foundation (WWIF). The HaloSource story began in 1998, when Dr. Jeffrey F. Williams, professor of microbiology at Michigan State University, assembled a strategic alliance of scientists and industry experts to make water better.
The FEDI-2Rx fractional electrodeionization product range is designed for applications in pharmaceutical, biomedical and laboratory applications in which installations require hot water sanitization to meet pharmacopoeia standards for purified water and water for injection.
Chlorine is and has been the No. 1 disinfectant used by water treatment systems throughout the world for more than 100 years. Currently, a majority of municipal water systems use chlorine to disinfect their drinking water. Recently, though, concerns over chlorine’s limitations have emerged, and research into alternative disinfectants is ongoing.
New disinfection options may provide alternatives to traditional chlorine
As winter becomes nothing more than a memory and the days get warmer, our thoughts are quickly turning to the lazy, hazy days of summer. And nothing is more refreshing on a hot summer day than a dip in the pool.
UV systems offer treatment option with fewer chemicals
Reading the Centers for Disease Control and Prevention’s (CDC) Web pages on recreational water illnesses (RWIs) is enough to make someone never want set foot in a swimming pool again. From the list of pathogens that can cause RWIs (which includes some nasty fellows, such as Cryptosporidium, Legionella, E. coli and more) to statistics on sources of disease (“on average, people have about 0.14 grams of feces on their bottoms”), the cringe factor is high.
The H2gO purifier is a handheld 3-oz device that converts a few grains of common salt into a powerful disinfecting solution in seconds. It can treat 1 to 20 liters of water at a time and never needs replacement parts. The purifier is simple to use and free to operate. It is driven by a cell phone battery that can be charged by the integrated solar panel or USB, and is able to treat 300 liters of water per charge. There is an LED flashlight for nighttime operation.
These residential UV systems can treat water at a variety of flow rates, from 7 to 20 gpm. Features include a stainless steel chamber, electronic ballast and an alarm to indicate lamp usage or power failure. The MWC-ES Series includes a solenoid valve to shut off the water supply in case of outages, and the MWC-EM Series has an additional UV meter to monitor wavelength.
UV Superstore Inc. launched a new website for improved user experience and enhanced functionality. It features an extensive search and cross-reference of replacement UV lamps, quartz sleeves and other consumables for use in most UV water and air treatment systems. The new website features UV Superstore brand UV treatment systems, with models for residential and commercial/industrial applications. Designed to give the user access to the company’s knowledge base, which comes from many years of experience, the new website is designed as an online tool to find “anything UV.”
Rosedale offers a wide variety of filtration systems for environmental and remediation markets. The automatic backwashing filtration system determines when the dirt load is too great and backwashes the element clean, all unattended. Rosedale filters can remove large quantities of sediment, hydrocarbons and protozoan cysts such as Giardia and Cryptosporidium. With high flow rates and dirt-holding capacities, they will meet a wide variety of needs. Elements are easily disposed of by incineration or at solid waste landfills.
The RIO Zuni generates 1 or 2 lb of chlorine-equivalent mixed oxidant solution chemistry from salt for biofilm and airborne bacterial control in process and makeup water disinfection per day. The system is designed for minimal maintenance with no storage or handling of hazardous chemicals. It can handle up to 170 mg/L hardness without softening and has an optional integrated brine tank and remote monitoring capabilities. This cost-effective solution is ideal for industrial and commercial cooling towers.
