UV (Ultraviolet) Systems

Application: UV Disinfection of Dam Water for Safety Showers and Ablutions
Dam water at a mine site is pumped into a plant room where it undergoes a three stage treatment system. First multimedia filtration then oxidation with chlorine and then filtration with DMI media for iron removal. Clean water is then disinfected with a thin film ProMinent Dulcodes UV unit. The choice of thin film UV is due to the possible low UV transmissivity of the water. UV treated water enters a clearwater tank for storage and further chlorine disinfection.

The filtration and UV system is a turnkey package plant supplied by Dioxide Pacific. All plant items are mechanically and electrically installed in a portable building with an electrical control panel. The system was tested and commissioned prior to shipment. On site, only water in, water out, backwash water and power were connected.

Application: UV Disinfection of Leak Test Water for Car Production
For the production of new cars, vehicles are driven through a leak test bay where low pressure showers of water are sprayed over the vehicle. The aim of the sprays is to detect the presence of leaks around door seals. It is not possible to use chemicals in this water as the chemicals would react with paint finish and leave residues which would be unsightly. Therefore, the traditional method is to continually waste this water.

Dioxide Pacific was engaged to design, build and install a treatment system which did not involve chemicals but allowed water to be continually recycled. The system provided includes a recirculation pump, circulation pipework, multimedia filtration and UV disinfection. The UV chosen is a ProMinent Dulcodes thin film unit as the UV transmissivity can drop below 80%. UV disinfection maintains the Total Plate Count (TPC) below the acceptable level and allows the owner to recycle water continually.

Application: Chloramine Destruction of Swimming Pool Water
Chloramines are produced in swimming pool water through the reaction of chlorine with ammonia. Chloramines are responsible for pool hall odour and skin irritations. Traditionally, chloramines have been reduced through the use of ozone and GAC filtration or superchlorination, however these processes have inadequacies such as high capital and running costs. It has been proven that medium pressure UV destroys chloramines through photo-oxidation. The UV installation has low capital cost and low running costs.

Dioxide Pacific was engaged to supply, install and commission a Powerline 2kW UV unit for a commercial hotel spa. The installation has been successful, reducing the chloramine concentration to less than 0.2 ppm at all times.
