Res-Kem LLC is a supplier of residential, commercial and industrial
ultraviolet (UV) water treatment systems. Our UV purification systems are available
in a variety of sizes and configurations to meet the needs of
most water purification applications. For applications greater than 500 gpm,
multiple UV water systems can be combined in series or parallel to meet the
necessary flow requirements.
| Res-Kem ONLY sells Industrial or Commercial UV water treatment systems when they are part of a larger water treatment plant or project. |
Res-Kem is a distributor for UltraDynamics® and UVSI Ultraviolet water
disinfection systems. Res-Kem offers 254NM UV lights for bacteria control
and 185NM UV lights for TOC control. Res-Kem can create a complete and efficient
ultraviolet water treatment system by using a standard or non-traditional
UVSI industrial UV light water treatment system customized for your application and installation.
Why use an Industrial UV Water Treatment System?
Ultraviolet (UV) light, specifically the 254 nm wavelength, is a powerful disinfectant.
The chief advantages of using UV water systems over chemical treatment are:
- No Residual Chemical or hazardous by-product at the end of the process.
- UV water systems offer a "natural" and "green" choice for disinfection and purification of water.
An ultraviolet water purifier is a simple yet effective way to destroy
microorganisms in water. A typical UV water treatment system uses an
ultraviolet light to kill microorganisms, and may be combined with a water
filter to trap these and other contaminants.
How does Ultraviolet Light Disinfect Water?
Short wave UV and Vacuum UV are able to penetrate the cell walls of
microorganisms, and subsequently disrupt the cells in such a way as to
prevent them from replicating. Microorganisms that are unable to replicate
are unable to cause human infection or create damaging situations
for manufactured products or processing equipment.
The primary mechanism by which UV inactivates microorganisms is the
creation of Pyrimidine Dimers. These are bonds that are formed between
adjacent pairs of thymin or cytosine pyrimidines on the same DNA or RNA
strand. Once the dimmers are formed the microorganism is "locked up"
and unable to reproduce.
The peak wavelengths for cellular penetration and disruption are in
the range of 250 – 270 nm. This is why low pressure UV lamps with a peak
output of 253.7 are so effective for disinfection purposes.

Advantages of UVSI UV Water Systems
The drawback of traditional UV water systems is the stainless steel chamber.
Although stainless steel meets stringent quality and strength requirements,
it absorbs UV light energy. As much as 90% of the ultraviolet light emitted
by the lamp is wasted because it is absorbed into the stainless steel housing.
To get around this problem manufacturers have to pack the unit with multiple
UV lamps, as many as 44 in one treatment chamber. Additionally, numerous chamber
baffles are installed to ensure sufficient water mix for adequate UV light exposure.
The disadvantages of traditional UV water systems include:
- Wasted UV energy
- High Energy Costs
- Multiple Lamps
- Large foot print
- High ongoing maintenance expense
Until now Res-Kem just offered traditional UV water systems to our customers.
We are excited to offer an innovative, non-traditional UV light by
Ultraviolet Sciences. This newly patented UV water system design addresses
all of the disadvantages of the traditional UV water purifier.

Very Little UV Energy is Wasted
Traditional UV disinfection chambers lose better than 90% of their UV light
energy into the outer wall. The treatment chambers of the UVSI light utilize
a specially designed highly reflective flow tube that does NOT absorb
the light energy, but continues to reflect until it is finally
absorbed by a microbe. The result is improved efficiency and performance.
Lower Energy Costs
The result of the highly reflective chamber design is that the UV light
energy (photon) remains in the water until finally absorbed by a microbe
or chemical molecule such as chloramine. The net effect of the high
reflective chamber is a 3X to 7X improvement in efficiency when compared
to an equivalent flow rate system. Keeping the UV photon in the water
instead of turning it into heat as the housing absorbs it,
delivers significant improvement in disinfection performance.
Fewer and/or Shorter Lamps – Reduced Size – Smaller Footprint
As is evidenced by the picture above, the number of UV lamps required by the
UVSI Ultraviolet water systems is dramatically lower than that of the
competition. In addition to lower energy costs, having fewer and smaller
lamps reduces the footprint necessary to accommodate the UV water system
and the annual expense of UV lamp replacement.
Uniform Flow to Ensure Proper UV Dosage
An added benefit of the highly reflective UV water treatment chamber
is that the UV dose is very uniform throughout the volume of water.
Uniform UV energy dose is critical for TOC removal and Urea reduction.
This is difficult to achieve with traditional UV water systems due to
the poor transmittance of 185 nm UV through even the "cleanest" water.
The UVSI patented UV water system resolves this problem, delivering high
levels of UV energy, uniform in dosage, inside the flow chamber for both
185 nm and 254 nm wavelengths.
Having a uniform flow pattern throughout the UV water treatment chamber
creates an optimal situation for delivering a predictable UV disinfection
dose. Fluid dynamic modeling tools were used to optimize the flow tube
annulus, resulting in a chamber that has a uniform flow rate. The relatively
small size of the chamber results in turbulent flow over a wide range
of operating flow rates. Only a single baffle is needed at the inlet.
This uniform flow rate coupled with the highly reflective chamber delivers
a uniform UV dose throughout the entire chamber length.
