OVERVIEW
Each UV system is designed to treat water at specified flow rates as outlined in the specification
sheet. All EcoStream units are provided with two main component parts, specifically the ultraviolet
reactor chamber and the main controller.
Reactor Chamber
The reactor chamber is manufactured from stainless steel 304L and houses the ultraviolet lamp and
quartz sleeve. All EcoStream Lite UV systems use only a single UV lamp. The lamps are of a special
high intensity, high output germicidal type. The chamber is designed to mount both horizontally or
vertically and should be secured to a suitable support.
Power Supply
The main power supply is connected to the chamber via 1.5 meters of cable to allow for application
flexibility. In case an extension is required,
do not cut the cable
. Use an extension box or surface
mount electrical socket.
PRODUCT APPLICATION
Ultraviolet disinfection provides a simple, inexpensive way of destroying bacteria, mold, virus, algae
and fungi without the use of heat or chemicals. Each EcoStream system is designed to achieve a
specific energy dose to properly destroy microorganisms.
UV Disinfection is affected by many factors and the following should be looked at prior to the
installation of the UV system:
1.
UV Transmission (transmittance) deals with the effectiveness in which the 254 nanometer
wavelength of ultraviolet light is transmitted through the water. The higher the transparency of
the water, the more effective the UV system becomes.
As a general guideline, the following are some typical UV transmission rates:
Deionized or reverse osmosis water
: 90 - 98%
Typical filtered fresh water
: 85 - 94%
Lakes, wells, or other private sources
: 70 - 90%
*** WARNING -- DO NOT UNDERSIZE UNITS ***
If exact transmission quality needs to be determined, have samples tested at a suitable lab using
a proper spectrophotometer (@ 254nm). Alternatively, you may contact Alfaa UV for a sample
analysis.
2.
Suspended Solids will act against a UV system by effectively shielding microorganisms from the
ultraviolet light. Dirt, rust, turbidity, etc. all have the ability to block out the UV light. It is
absolutely necessary to properly control the level of suspended solids by properly pre-filtering
the liquid prior to disinfection (pre-filtration down to 5 micron is considered the minimum).
3.
Total Dissolved Solids of around 500 ppm can drastically reduce the rated flow rate of the unit by
absorbing UV energy. Proper pretreatment of high TDS levels must be taken into account.
