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 meter and 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.

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.

Injecting chlorine into a pipeline using a turbine positive displacement pump

A Hydro Instruments chlorinator/sulfonator system feeding a pipe line using a turbine positive displacement pump. The pressure relief valve must discharge to a drain or outside of the building. Note the by-pass of the piping from the pump discharge through a by-pass valve back to the suction side of the pump.
Note 1: The by-pass valve must never be completely closed.
Note 2: The pump suction and the ejector must be installed into the side of the pipeline, not the top of the main.
