Wastewater Laboratory Procedures provides critical
and important instructions and tips on how to perform laboratory
analysis on wastewater. The class addresses the following topics:
Laboratory equipment – standard solutions and titration – use of
spectrophotometer–laboratory safety–sampling and preservation of
samples – settleable solids – sludge solids – mixed liquor – sludge
age – dissolved oxygen and BOD – pH – chlorine residual – ammonia
nitrogen – microbiological examination and E coli test. Learn about new
testing and reporting regulations.
A free Laboratory Analysis Review Manual is provided.
