New in design, very compact and highly efficient, with the stamp of our focus on quality: high grade electro polished stainless steel, and a superior leak proof design.
Using stainless steel direct from Salem Steel, each ESC Lite Chamber is electropolished assuring better surface finish and corrosion free performance.
Perfectly matched and suited for the UV lamp the new ECS Lite power supply provides upto 50% greater UV output as compared to local ballasts/power supplies which are typically designed for tubelights.
Assured performance in a compact design. Uses same technology used to design rockets and Formula 1 cars!
Each ECS Lite uses only genuine high purity fused silica Quartz directly imported by Alfaa UV. Better quartz = better efficiency.
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 (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‰ |

UV Disinfection System is an extremely effective way to combat microbial contamination in water. However, microbes have to be exposed to UV-C light in the proper amount in order to effectively disinfect the water. UV Disinfection Systems are used in many different applications ranging from the purification of drinking water in individual homes to disinfecting water supply of entire townships to industrial wastewater treatment. UV treatment for water is recognized as a safer and more cost-effective way to disinfect water for industrial applications
In UV water disinfection technology, Ultraviolet light of wavelength 253.7 nanometers is used for disinfection of bacteria, viruses, molds, algae, and other microorganisms, which multiply and grow. UV disinfection technology destroys the DNA of microorganisms which leaves them dead and unable to grow further. UV disinfection technology can be used for drinking water disinfection, process water disinfection, wastewater disinfection, and surface disinfection. Other than disinfection applications, this technology can also be used for TOC removal and Ozone destruction. Plus, there is the UV sterilizer for hospitals, factories and offices.
In the UV water disinfection technology, the UV light disinfects by penetrating microorganisms and destroying their DNA. DNA plays an important role in organisms’ functions and reproduction hence destroying the DNA prevents the organism from being active and multiplying. This UV energy (wavelength of 240-280 nm) is also naturally found in sunlight in very small quantities. The same energy is produced in stronger intensities with the help of high mercury discharge lamps, commonly known as UV lamps.
Ultraviolet disinfection system is not simply a lamp inside a pipe. The UV Reactor must be designed to ensure that all microbes receive sufficient exposure to the UV light (dose). Based on the hydraulic properties of water; the reactor needs to be optimized to guide the flow in a manner so as to maximize residence time and boost turbulence.
