Agricultural Analysis
Systems for Agricultural Analysis. This catalog describes chemical
analysis systems for soil, greenhouse media, sap, plant tissue and fluid
fertilizer.
Biochemical Oxygen Demand
"A Comparison of the Graphical and Standard Methods for the
Determination of Biochemical Oxygen Demand". By Stephen L.
Woodring and Dennis A. Clifford. Reprinted from Journal Water
Pollution Control Federation, Vol. 60, No. 4, April, 1988.
The Graphical method was found to increase reliability in BOD data and
give more confidence in very low BOD levels obtained in testing secondary
and tertiary effluent of biological processes.
"Graphical Method for Calculating Biochemical Oxygen Demand". By
Robert J. Klein Jr. and Charles R. Gibbs. Reprinted from Journal Water
Pollution Control Federation, Vol. 51, No. 9, September, 1979.
Presents a graphical technique for handling BOD test results that
automatically corrects for blank and seed, permits uses of dilution water
with a higher demand concentration, does not require an initial DO
determination and provides added information.
Introduction to BOD
This brochure describes Hach's biochemical oxygen demand system. A
method to make dilution water quickly is included.
Introduction to Biochemical Oxygen Demand. By Clifford Hach, Robert
L. Klein, Jr. and Charles R. Gibbs, 1988.
Provides answers to the questions: What is BOD? What is the
significance of BOD? How is BOD measured? How reliable is the BOD
test?
Chemical Oxygen Demand
Hach COD system for Wastewater Testing. Describes a semi-micro COD
monitoring system with ready-to-use sample vials. Includes a cost
comparison.
