Economical pollution control in warm climates by contact stabilization wastewater treatment

Water pollution abatement with economical solutions, for wastewater treatment plants design and operation, is a crucial problem, especially for economically developing countries. The purpose of this study is the evaluation of the contact stabilization process to achieve economical secondary treatment as well as partial nitrification under favorable temperature conditions. The examined variables are easily definable parameters of practical importance for any wastewater treatment plant. Based on full scale plants data, correlations between design or operation variables and plant performance or effluent quality are reported.
