The function of this ultraviolet disinfection unit is to provide in excess of 99.9% reduction of all water borne pathogenic
(disease causing) bacteria.
Model ATS series have a number code designation correspondent to the maximum GPM
(gallons per minute) flow rate of the unit. I.E, DWS-25 has a maximum flow capacity of 25 GPM.
Applications: DWS Units are designed to destroy micro-organisms in water supplies. The Ultraviolet lamp peak
radiation of 254 nanometer wavelength (nm) destroys or inactivates the D.N.A. (deoxyribonucleic acid) which absorbs the
Ultraviolet radiation, preventing cellular reproduction. These units meet minimum dosages of 30,000 microwatt second
per square centimeter.
MAXIMUM CONCENTRATION LEVELS BEFORE ULTRAVIOLET:
Turbidity.................................5 NTU
Color.......................................None
Manganese........................0.05 ppm
*Note: Pre-filtration equipment may be required if these parameters cannot be maintained. Flow rate must not exceed
rated capacity of the unit.
The DWS series has an unique design with an ultraviolet germicidal lamp housed within a single quartz sleeve surrounded
by a stainless steel pressure chamber. The chamber is fabricated out of 304 Stainless Steel. A removable stainless steel
cover exposes electrical components for servicing, when required.
The DWS series come with an U.V. lamp designed with one pin at the end. This type of lamp has a socket connected to
each pin.
A stainless steel threaded nipple with a brass compression nut and O-Ring is located at each end of the disinfection
chamber.
The quartz sleeve is intended to be placed through the disinfection chamber and will slightly protrude through the
threaded nipple. The ultraviolet lamp is placed within this quartz sleeve. The U.V. light shines through this specially
designed hard quartz sleeve for maximum disinfection efficiency to meet the requirements for bacteria reduction in
potable water.
The inlet/outlet are located on one side of the chamber and may be interchanged as to designation dependent upon
installation. A site port is provided for safe and easy view of operation.
