CWPUV(Clean Water Plant) Series

The BacStop TST technology is a method of treating water to kill bacteria and prevent the growth/re-growth of microbes harmful to humans and animals. Using metal ions, principally nano concentrations of polyvalent silver oxide. TST is released into the water by erosion of a solid balls made from silver oxide (TST). The balls are contained and dispensed from within a special inline dispenser. The system takes advantage of the oligodynamic effect provided by the addition of silver to water.

Sedimentary Filter
All machines have a cartridge filter system located after the BacStop dispenser. The filters are nominally rated at 1-10 micron (depending upon conditions), all particles larger than the specific sized filter will be removed from the inlet stream. The filter system is meant to remove large particles, which could impact upon the disinfection capabilities of the machine. The number of filter housings varies with the size of machine. Typically, other forms of filtration may precede the cartridge pre-filters.

Activated Carbon Filter
All machines utilize cartridge activated carbon (AC) filtration. AC is most effective in removing organic contaminants from water. Organic substances are composed of two basic elements, carbon and hydrogen. Because organic chemicals are often responsible for taste, odour, and colour problems, AC filtration can generally be used to improve aesthetically objectionable water. Similar to other types of water treatment, AC filtration is effective for some contaminants and not effective for others. AC filtration does not remove microbes, sodium, nitrates, fluoride, and hardness. Lead and other heavy metals are removed only by a very specific type of AC filter. The consumer should assume that the AC filter is not effective in removing them. Refer to the other available BWT information in the treatment of systems that do remove the contaminants listed above.

Ultraviolet
The deployment of chlorine, chlorine dioxide, oxychloride and other chemical substances to disinfect liquids is not always practical or desirable. It has been scientifically demonstrated UV technology is a suitable alternative to chlorine disinfection. The intensive research and technologically mature disinfection method with ultraviolet light is adapted from the natural action of sunlight. UV light can be deployed in a versatile fashion. It is suitable for disinfecting water, for destroying harmful microorganisms in other liquids, on surfaces and in air.

Pumps
CWPUV series machines are equipped standard with Grundfos Centrifugal pumps (Other pumps types are optional). The pumps are specifically specified to deliver constant high-pressure flow ideal for water disinfection systems operation.

Pressure Gauges
CWPUV series machines include stainless steel, glycerin-filled pressure gauges mounted into various locations in the machine’s piping to yield pre-filter and post-filter pressure readings. The machines typically operate at a pre-filter pressure of 100 – 300 kPa with a 20 – 40 kPa pressure drop across the plant. Depends upon model and/or condition of filter element.
