CHEMICAL SHIPPING AND FEEDING
Sources of Information. Process chemicals used in
wastewater treatment vary greatly in their specific requirements
for safe storage and handling. Several industrial associations,
including the Chlorine Institute, the National Lime Association,
the Manufacturing Chemists Association, and the National Fire
Protection Association (NFPA) provide information for operators.
In addition, chemical manufacturers will supply handbooks and
chemicals upon request.
Table 14 provides information about various chemicals
commonly used at WWTPs, including their common names, formulas,
and most common uses. It also covers the forms and containers in
which they are usually obtained commercially and general
characteristics of the chemicals. Table 15 presents information
about feeding these chemicals, including the most common forms
for feeding, the amount of water needed for continuous
materials for storage and handling.
