Markel Technology Leads The Way To A Cleaner Environment
In the “Land Down Under” a Markel FEP coil is contributing to the success of a new home appliance. Earth Safe Australia has patented a water purification device to treat gray water. Effective in June a law requires all new homes and apartments to have a rain water cistern or a device to treat water from showers and basins for reuse in toilets, washing machines and gardens. The new device uses ultraviolet light to kill pathogens in the water as it flows through the Markel coil. It has received accreditation from the New South Wales Health Department. Initial production began in March.
A device manufactured in Switzerland employs a Markel coil in a device to purify water used to clean instruments used in hospitals. Their US division is developing a unit for decorative fountain displays. A drinking water device has been submitted for approval by the Italian Government. In Canada, coil based UV systems are in development for treating machine tool lubricant, blood and contaminated ground water. Production will start soon of a drinking water device in the Philippines by a large multi-national appliance manufacturer. Customers in the USA use Markel coils to treat ground water contaminated with MBTE, a dangerous chemical used in gasoline, to dispense purified water in a bottled water packing machine and to treat cooling water in a pulsed power generator. Non-UV applications for coils include air sampling, dispensing of de-ionized water in the production of integrated circuits and heating and cooling of chemicals.
The use of ozone is another way to treat water. Applications that require ozone injection commonly use point source devices such as porous ceramic stones or stainless steel venturi injectors. Markel microporous PTFE tubing offers a useful alternative. Designers can now spread ozone bubbles into areas in spas, ponds fountains and aquariums that can not be treated with point sources. Ozone bubbles exit along the entire length of the tubing. A customer has recently started production of a device to treat water in car washes and laundries using Markel tubing. A project is under way to design a small system to treat water in hot dog vending carts. Tubing has been installed in a greenhouse to document the successful acceleration of plant growth seen last year. Tests will be made later this year in fruit washing, biofilm reduction in cooling water towers and odor control of sewer gas. Experimental use in aquaculture was interrupted by hurricanes in Florida. A substantial potential exists in this field as world markets turn to farm raised fish and shrimp to supplement ocean fisheries.
The initial use of microporous tubing was in a gas transfer application. Hydrogen was extracted from a chemical slurry for use in a power cell. Perhaps environmental friendly automobiles powered by hydrogen will become popular and Markel will supply a key component. An instrument manufacturer plans to use Markel tubing to selectively collect samples for analysis in a gas chromatograph.
