Abstract

Industrial wastewater contains a variety of volatile chemical constituents. The large majority of the volatiles are organics. Many of these volatile or¬ganic compounds (VOCs) end up in the effluent to wastewater treatment plants. It is necessary to estimate the emission of the VOCs from sewerage plants in order to study the fate of these volatile organic compounds.

This study focuses on the estimation and comparison of the emission of 28 volatile organic compounds from the water and air in four operation units of Linden Roselle Sewerage Authority (LRSA) wastewater treatment plant. The removal rates of these target compounds have been calculated via mass balance by determining the difference between their concentra¬tion in water at each stage and the previous stage. Although the effect of specific removal mechanisms was not studied, thermodynamic calculations were made to check the results of air and water sampling.

The total calculated removal rate of all 28 target compounds was 3251 kg/day. Of this total, it was assumed that 70% of the nonpolar compounds and 10% of the polar compounds were emitted to the air.
