Benefits of UV sterilisation
No microbe can withstand UV rays even those pathogens that cannot be killed by chlorination
No longer risk exposure to harmful pool chemicals which can be 5 times worse than passive smoking
No undue composite building structure corrosion as caused by chloramine
No unpleasant chloramine smell you get from residual chlorine
No eye and skin irritation as caused by chlorine

Principle of Operation
UV water disinfection system design has been carefully conceived to provide adequate germicidal dosage throughout the disinfection chamber. The dosage, as it applies to UV disinfection, is a function of time and the intensity of UV radiation to which the water is exposed. Exposure time is related to the flow rate, the higher the flow rate, the lower the exposure time or the lower the flow rate, the higher the exposure time. The UV intensity is the amount of energy, per unit time, emitted by germicidal lamp. The Dosage is the product of UV intensity and the exposure time.

Limitation of Use
The UV water disinfection system NOT intended for the treatment of water that has an obvious contamination or intentional source, such as raw sewage, nor is the unit intended to convert wastewater to microbiologically safe drinking water.

Water Quality (in)
Water quality plays a major role in the transmission of germicidal UV rays. It is recommended that the water does not exceed following maximum concentration levels

Maximum Concentration Levels (Very Important)
Iron≤ 0.3ppm(0.3mg/L)
Hardness≤ 7gpg(120mg/L)
Turbidity≤ 1NTU
Manganese≤ 0.05ppm(0.05mg/L)
Tannins≤ 0.1ppm(0.3mg/L)
UV Transmittance≥ 750‰

Effectively treating water with higher concentration levels than listed above can be accomplished, but may require added measures to improve water quality to treatable levels. If, for any reason, it is believed the UV transmission is not satisfactory, contact the factory.
UV wavelength (nm)

DOSAGE is the product of intensity & time
Dosage=intensity*time=micro watt/cm2*time=microwatt-seconds per square centimeter
(μ W-s/cm2)
Note: 1000μ W-s/cm2=1mj/cm2(milli-joule/cm2)

As a general guideline, the following are some typical UV transmission rates (UVT)
City water supplies850-980‰
De-ionized or Reverse Osmosis water950-980‰
Surface waters(lakes, rivers, etc)700-900‰
Ground water(wells)900-950‰
Other liquids10-990‰
