(3) Reactor effluent will contain approximately 70
percent hypochlorite and 30 percent chlorine dioxide.
Approximate yield is 0.4 lb ClO2/lb Cl2. Near 100 percent
conversion to chlorine dioxide can be achieved by available
recycle equipment. (Yield = 1.0 lb ClO2/lb Cl2)
(4) Practical dosage range of 6:1. System
operating as flow proportional should provide acid injection
directly upstream from the chlorinator injector to maintain
optimum pH.
(5) Chlorine dioxide solutions are unstable in
open vessels. Solution lines and diffusers must be designed so
there is minimum possibility of chlorine dioxide coming out of
solution.

Chemical Feeders.
See Table 23 for applications of
various types of feeders.
a) Dry Feeder Accessories. Dry feeders may require
specific auxiliary equipment or accessories when the chemical to
be fed has unusual characteristics. Accessories and the
conditions under which they are used are as follows:
Accessory
Characteristics of Material
Requiring Use of Accessory
Agitator
Arches in hoppers
Rotolock mechanism
Tends to flood
Dissolving chamber
To be fed in solution
Dusty
Vapor collector
Noxious or irritating
fumes
b) Feeder Construction. Mechanisms of feeders must
be constructed out of materials resistant to substances to be
handled. See Table 20 for guidance on materials selection.
c) Feeder Accuracy.
The accuracy of feeders should
be in these ranges:
