Function
Description
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) ow rate of the unit. I.E., GDS-8 has a maximum ow capacity of 8 GPM.
Applications: GDS 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. GDS 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-ltration equipment may be required if these parameters cannot be maintained. Flow rate must not
The GDS 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.
These units come with an ultraviolet lamp designed with four pins at one end.
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 efciency to meet the requirements for bacteria reduction in
potable water.
The inlet is located on the bottom of the chamber and the outlet can be on either side dependent upon installation. A
sight Port is provided for safe and easy view of operation. A bracket is secured to the wall and the chamber is held in
place by tightening the lock nut to both mounting bracket and chamber.
