The UV disinfection unit is designed for disinfection of drinking and industrial water by exposing it to ultraviolet radiation with a wavelength of 253.7 nm, which has the greatest bactericidal effect. This method does not lead to a change in the chemical composition of water, allows you to abandon the use of reagents for disinfection (for example, chlorine) or significantly reduce their concentrations.
The installation consists of two units – an irradiation unit (irradiator), in which water treatment takes place, and a power supply and control unit. In installations, the blocks are fixed on a supporting frame, which is installed on the floor or a solid base. The units can be mounted on a wall or on a base.
The installation is designed for continuous operation. Frequent switching on and off of the power supply of the installation is not recommended, as this may lead to a reduction in the service life of UV lamps.
If the impurity content in the water exceeds the specified levels, its preliminary purification is required. In any case, it is recommended to mount a filter of mechanical impurities with a filtration fineness of no more than 5 microns before installation.
Each installation consists of two units – an ultraviolet irradiation unit (irradiator) and a power supply and control unit.
The irradiator is a cylindrical container made of stainless steel, along the axis of which there are five quartz tubes. Inside each quartz tube there is an ultraviolet lamp. Connectors of power wires are connected to the electrodes of the lamps at both ends of the irradiator. The power wires that fit to each end of the irradiator are combined into cables that have connectors at opposite ends for connection to the power supply and control unit.
The power supply and control unit is a metal rectangular box, on the front surface of which there is an LED indicating the presence of mains voltage "NETWORK" and numbered emergency LEDs "ACCIDENT" according to the number of UV lamps in the installation.
The glow of each of the "ACCIDENT" LEDs signals the absence of a UV lamp current with the corresponding number. On the lower surface of the unit there are two connectors for connecting the power cables of the irradiator, a fuse and the input of the network cable. There is a power switch on the side or front surface of the unit.
