Recommended notation for use in the description of biological wastewater treatment processes

Abstract

The Executive Committee of the International Association on Water Pollution Research and Control (IAWPRC) and the Commission on Water Quality of the International Union of Pure and Applied Chemistry (IUPAC), appointed a Working Group in 1980 to prepare a proposal for unifying notation used in the description of biological wastewater treatment processes. The task was motivated by the benefits that would result if a common notation was used for the dissemination of results in international publications. In beginning the task of proposing a common notation it was recognized that unless the Working Group used established practice and common acceptance as a basis for symbol choice, it would be difficult to get authors to adopt the recommendations. Therefore, a number of journals and books within the English, French, German, and American literature were reviewed in order to establish the quantities most often symbolized and to determine the symbols most commonly used to denote the quantities. As a result the proposal consists of a limited number of quantities for which symbols have been chosen and the choice is based generally on common practice. It is recommended that all contributors to IAWPRC and IUPAC publications conform to the proposed notation for a period of one year. After this period, a review of the original proposal will follow and a revised notation list agreed upon for compulsory use. © 1983 IUPAC
