yourself with the contents of
this manual before proceeding
with installation and operation.
SYSTEM APPLICATION
The Hydra-Max dechlorination
system is designed to accept
2⅝ " d i a m e t e r E n v i r o - C o r
Bio-Max dechlorination tablets. The most common
application for the Hydra-Max system is dechlorination of
water ows during re hydrant ushing. The system can
also be utilized for ushing new water mains or backushing
swimming pools. An aluminum tablet cartridge contains
multiple ¼" ow ports to provide the proper amount of
mixing and contact with tablets. This allows for complete
neutralization of chlorine and chloramines while keeping
chemical waste to a minimum. The Hydra-Max system
provides a fast and simple set-up that saves operators time
and money. There are no mechanical parts that require
adjustment or components that can be easily damaged
or broken. The compact, durable one piece construction
offers operators a low cost, low maintenance system.
HOW THE HYDRA-MAX®SYSTEM WORKS
The Hydra-Max system is a ow rated device designed
to safely apply chemicals in pressurized applications to
remove residual chlorine. The Hydra-Max dechlorination
system provides consistent and precise neutralization of
chlorine to meet stringent water treatment requirements
mandated by Federal, State and Local regulations.
The Hydra-Max system can be used for treating water
ows discharging from re hydrants, swimming pools
and new water mains. When
backushing swimming pools or
ushing new water mains, the
Hydra-Max system is typically
installed at the discharge
point of the water ow and
connected to a hose specied
for these applications. The
Hydra-Max system incorporates
a 2 ½" NST coupling for easy
and fast connection to any re
hydrant. The outlet incorporates
2 ½" NST male threads for use
with hoses, pilot gauges or
other test equipment. During
operation, ow enters through
the inlet hub and is channeled
through the compact dosing
chamber. As ow passes
through the system, it dissolves
the dechlorination tablets to
provide complete removal of
free and combined chlorine from
the ow. It is recommended that you check the removable
tablet cartridge after 15 minutes of operation. If needed,
add tablets and continue ushing.
SYSTEM PERFORMANCE
The Hydra-Max dechlorination system has been designed
for a ush rate of 150 to 900 GPM with chlorine levels
up to 4 ppm. The complete set-up time is 1-3 minutes
and typically requires only one operator. The Hydra-Max
system provides a fast and easy way to dechlorinate
pressurized ows in the most cost effective and efcient
manner when utilizing Norweco’s Enviro-C or Bio-Max
dechlorination tablets.
