Designation of ultraviolet sterilizers.
Ultraviolet sterilizes are used in cases when pathogenic microorganisms are needed to be eradicated or prevented against growth. Water disinfection is widely used in the following spheres:
- Drinking water treatment;
- Process and domestic waste water treatment;
- Medical drug preparation in pharmaceutics (in this case ultraviolet radiators are installed in sterile water closed circuits, inside reactors);
- End drinking water abstraction points (where local sterilizers are installed).
Operation concept.
Operation of water sterilizers is based on intolerance of a great number of microorganisms to intensive uv exposure. Thanks to uv intensive radiation the structure of all bacteria, viruses and protozoal microorganisms exposed to such radiation breaks down. The entire process takes no more than 5 seconds.
Design
An ultraviolet lamp is a main operating component of a sterilizer. In order to ensure safety upon contact with water flow and increase service life, lamps are enclosed in a tough sheath made of quartz. Lamps are mounted inside a working chamber. Water flow constantly passes through the chamber and is being processed as exposed to uv radiation. The sterilizer performance parameters (flow rate, radiator quantity and output) are selected in such a way as to provide sufficient time for eradication of all microorganisms. A control and monitoring unit provides the sterilizer operation management. This unit receives signals reflecting the lamp status and the necessity for its replacement in case of need. The sterilizer shall be periodically flushed in the course of its operation. In continuous mode of operation the sterilizer shall be flushed at least once every three months.
Equipment advantages:
- Efficient disinfection ensuring full eradication of all microorganisms;
- No need for additional reagents during operation;
- No generation of accessory substances during treatment process;
- Simple design and reliability of operation;
- Low power consumption (0.03–0.04kw/h);
- Operation of the sterilizer safe for humans.
