1410 SEWAGE AND INDUSTRIAL WASTES November 1958

and thermal conductivity; Industrial

Instruments, Inc., provided a conduc

tivity bridge and a four-point recorder for conductivity; the Brown Instru

ments Division of Minneapolis-Honey well Regulator Company loaned a

six-point pH recorder; Beckman In

struments, Inc., loaned a redox poten tial flow-cell and amplifier; Fischer &

Porter Company cooperated in many

ways by supplying ORP cells, flow

meters, a redox potential and tempera ture recorder ; the Wheelco Instruments

Division of Barber-Colman Company

provided a strip-chart recorder for

Chromatographie gas analysis studies. The research reported herein was

sponsored by several agencies. Low

level isotope studies were sponsored by the National Science Foundation;

high-level studies were supported by the U. S. Atomic Energy Commission

and the Engineering Experiment Sta

tion of Georgia Institute of Technology. The work on gas chromatography was

sponsored by the National Institutes of

Health. Without financial support

from these agencies these investigations could not have been carried out.
