Device for the Treatment and Disinfection of Solids and Fluids by Laser Radiation

The invention is designed to treatment and disinfection all kinds of solids and fluids (liquids and gases), characterized by use generators emitting laser in pulsed and continuous wave within the limited of 0.38 to 1000 microns, to which they are installed in his head terminal (output coupler) a device consisting of a diverging lens of zinc selenide (ZnSe), gallium arsenide (GaAs), fluorite (CaF2), germanium (Ge), quartz (SiO2) or similar material, variable opening under the surface to be treated. The device, for treatment in manhole, deposits or similar, like may be a reflective metallic element of semispherical, conical or polygonal, located at the bottom of the cavity, which is completely coated with a reflective foil equally Aluminum, Copper, Stainless steel or similar material. It is in the scope of technology laser Visible (VIS) and infrared (IR) for the disinfection of micro-organisms and surfaces cleaning.

The radiation from the visible to far infrared wavelengths comprises between 0.38 and 1000 microns, and in relation infrared radiation we have to specify that it is not possible to see it, but if to feel it in the shape of the heat. Radiation disinfection is a physical process defined by the transfer of electromagnetic energy from laser generating source to the cellular genetic material from one organism located in a solid or fluid. The effects of this energy are to incapacitate the cell to reproduce and to eliminate it by heating, due to the big sensibility of the micro-organisms to high temperatures.

The radiation produces photo-physical reactions photo-activating the dynamic processes at the molecule and electronic activation in the atoms, originating one warming at different levels and changing to calorific energy. The effectiveness of radiation is a direct relation of the amount of calorific energy is absorbed by micro-organisms. This dose is the product of the intensity and the time of exposure to the intensity. Most of the micro-organisms require a very low level of energy to be destroyed.

The infrared laser pasteurization does not have any disadvantages in terms of the quality of the product, and because of its very low energy consumption, low prices, and the high availability of infrared lasers, it is cheaper than any of the commercial methods currently used.

This technology offers important advantages in comparison with other technologies:
• Lower energy consumption
• Action not ionize
• Zero environmental impact
• Long-lasting equipment
• Low-maintenance.

The application of this new technology of Infrared Laser IR, in the Treatment of waste water for his reutilization in substitution of the ultraviolet lamps UV, means a saving electric power of the order from 40 to 80%, according to the model of used laser, collaborating with it to the fulfillment of the objectives of the Kyoto Protocol and to the project of board of the European Union, and contributing to the protection of the environment by means of the reduction of CO2 emission.
