UV Water

There are seemingly endless possibilities in which SALtech's water treatment solutions can be deployed. Three markets have already been identified: general water treatment, homeland security, and dental water treatment. Homeland security is a relatively new market given the unfortunate events of September 11, 2001. We believe that a significant need for drinking water security will result as hostile activities continue throughout the world. Water treatment can be carried out in commercial, industrial and private settings. Each market segment has its own unique requirement, demographics and financial attributes.

For added safety and protection, SALtech can potentially design systems for virtually any potable water supply. It has numerous applications that include sinks and drinking fountains or any where else a person may obtain water. It is designed to render the bacteria harmless just prior to an individual drinking from the water source. Technology can be adapted to accommodate from small-scale systems (faucet, point of use systems) to medium scale systems (Storage tanks, mobile delivery systems, inline delivery) potentially to large-scale systems (drinking and wastewater treatment facilities). SALtech has designed a system for near point of use laser water treatment systems and methods.

Adaptations to the technology may include using solar electrical power, or other alternative energy sources, for remote treatment units. Its technology improves upon known methods to kill microorganisms in water. A “laser-based” water treatment system has never before been proposed, which gives SALtech a novel and cutting edge technological advantage over current UV treatment methods.

At least one laser light source (e.g. semiconductor lasers or a conventional UV laser) is incorporated into the treatment area. A filtration capability can be included near or before the entry point of the treatment area. Filtration can reduce or eliminate particles from water prior to laser treatment. Particles can cause light to be absorbed or scattered, thereby reducing the effectiveness of laser treatment, therefore filtration prior to laser treatment is preferred.

 

 

 
Comparison of the microbiologic quality of point-of-use (POU)-treated water and tap water

Activated carbon filtration devices placed on household faucets are used to improve the taste and odor of tap water. However, there has been a concern that the growth of bacteria capable of causing opportunistic infections in these devices might present a public health risk. The water quality from point-of-use (POU) water activated carbon treatment devices and that of tap water with POU-connections and tap water without POU devices were compared. The highest concentration of bacteria was found in POU-treated water. International Journal of Environmental Health Research, August 2004, vol. 14, no. 4, pp. 253-260(8)
