Illustrations
Chlorinators shown in the illustrations are from the Hydro Instruments.
Models 800/802 Series, which have a maximum capacity of 100 pounds of gas per day (PPD).
Higher capacity systems are configured in identical ways.
Models 300/302 series having a maximum capacity of 500 PPD.
Hydro Instruments sulfonator systems are configured in identical ways and are available in the same capacity levels.
 | Single point
application A Hydro Instruments chlorinator/sulfonator |
with an internal meter directly connected to an
ejector feeding a pipeline or basin.
| Single point
application using a remote meter A Hydro Instruments chlorinator/sulfonator |
connected to a single wall mounted
remote meter and ejector.
| Single point application using |
an automatic switchover standby
Two Hydro
Instruments chlorinators/sulfonators,
connected to a switchover unit feeding one remote meterand
ejector. When the current supply tank empties,
the switchover unit
automatically switches supply to the chlorinator/sulfonator connected to
the full tank.
| Multi-point
application A single Hydro Instruments chlorinator/sulfonator feeding multiple remote meters (two shown here), each connected to an ejector. Each remote meter-ejector pair (called a feed-point) operates independently. The maximum rate of gas at any given time drawn by all of the feed-points cannot exceed the single chlorinator/sulfonator capacity. |
Multi-point
application using an automatic switchover standby
Two Hydro
Instruments chlorinators/sulfonators,
feeding a switchover unit which is connected to multiple remote
meter-ejector pairs (called a feed-point). When the current supply tank
empties, the switchover unit automatically switches supply to the
chlorinator/sulfonator connected to the full tank. Each feed-point
operates independently and the maximum rate of gas at any given time drawn by
all the feed-points cannot exceed the connected
chlorinator/sulfonator capacity.
Injecting
chlorine into a pipeline using supply pressure
A
Hydro Instruments chlorinator/sulfonator
system shown here feeding a pipeline using supply pressure. The pressure of the
water supply to the ejector should be at least 40PSI greater than the
water pressure of the line into which the chlorine solution is being injected
("back pressure") in order to create a sufficient vacuum in the ejector.
Injecting
chlorine into a pipeline using a centrifugal pump
A Hydro
Instruments chlorinator/sulfonator
system feeding a pipeline using a centrifugal pump. Note the location of gate
valves for easy Y-strainer cleaning and practical pump maintenance.
NOTE: The pump suction should be 5 feet away from the ejector
injection point. On larger pipe diameters of 6 inches or greater, a distance of
10 times the pipe diameter should be maintained so that chlorinated water is not
recirculated through the booster pump.
