COD fractions in raw and mechanically treated wastewater
Journal Title: Civil and Environmental Engineering Reports - Year 2013, Vol 1, Issue 11
Abstract
The paper presents results of studies concerning the designation of COD fraction in the raw and mechanically treated wastewater in different year seasons. The research object was a mechanical-biological wastewater treatment plant with the output of >40 000 P.E., located in western Poland. The results of COD fraction in the raw wastewater were compared with data received in the ASM models. Methodology for determining the COD fraction was based on the guidelines ATV - A 131. During the research following fractions were determined: particulate slowly biodegradable substrates (XS), soluble readily biodegradable substrates (SS), inert particulate organic material (XI) and inert soluble organic material (SI). Soluble and particulate components were differentiated by filtration through 0.45μm membrane filters. The percentage of each fraction in total COD determined on the real concentration in raw wastewater are different from data reported in the literature.<br/><br/>
