Range of application

Bacteria cleaning uv sterilizer Principle
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

<5NTU

Manganese

≤0.05ppm(0.05mg/L)

Suspended solids

10ppm(10mg/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)

Bacterial cells will die in the UVC(200-280mm) irradiation. 253.7nm spectral line of low pressure mercury lamp has high bactericidal effect and concentrates more than 900‰ output energy of low-pressure mercury UV lamp

UV Dose

The units generate a UV dosage of at least 30,000microwatt-seconds per square centimeter (μW-s/cm2), even at the end-of lamp life(EOL), which is more than sufficient to destroy most waterborne microorganisms, such as bacteria, yeasts, algae etc….

DOSAGE is the product of intensity & time

dosage=intensity*time=micro watt/cm2*time=microwatt-seconds per square centimeter

(μW-s/cm2)

Note:1000μW-s/cm2=1mj/cm2(milli-joule/cm2)

As a general guideline, the following are some typical UV transmission rates (UVT)

City water supplies

850-980‰

De-ionized or Reverse Osmosis water

950-980‰

Surface waters(lakes, rivers, etc)

700-900‰

Ground water(wells)

900-950‰

Other liquids

10-990‰
