FUNCTION:

The function of this ultraviolet disinfection unit is to provide in excess of 99% reduction of all water 

borne pathogenic (disease causing) bacteria.

Model DWS/SE/DWSW series have a number code designation correspondent to the maximum gpm  

(gallons per minute) flow rate of the unit.  I.E.- DWS-7 has a maximum flow capacity of 7 gpm.

Applications:

Ultraviolet Germicidal Disinfection

A.T.S. Ultraviolet Disinfection 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.  A.T.S. Germicidal 

Disinfection units meet minimum dosages of 30,000 microwatt second per square centimeter.

MAXIMUM CONCENTRATION LEVELS BEFORE ULTRAVIOLET:

Turbidity.................................5 NTU 

         Hardness..........................................7 gpg 

Color.......................................None 

         Iron...................................................0.3 ppm

Manganese........................0.05 ppm 

         pH....................................................6.5 - 9.5ppm

Important Note - Pre-filtration equipment may be required if these parameters cannot be maintained.  

Flow rate must not exceed rated capacity of the unit.

DESCRIPTION OF EQUIPMENT:

The DWS/SE/DWSW series are of 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/SE series come with an ultraviolet lamp designed with one pin at each end.  This type of lamp 

has a socket connected to each pin.  The DWSW-8 model comes with a bi-pin connection at each end.

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 

from each threaded nipple end.  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 depen-

dent upon installation.  A Site Port is provided for safe and easy view of operation.
