p-H buffer capacity based monitoring of algal wastewater treatment

摘要

A pH buffer capacity based method for multivariate monitoring of tertiary algal wastewater treatment systems is presented. A pilot plant with algal biomass receiving the effluent of a carbon removing activated sludge municipal wastewater Treatment plant was used for the experimental work. Two types of buffer capacity profiles are considered, first resulting from A titration from the actual pH to pH 2.5 9 down titration), and second as a result of a titration from pH 2.5 to pH 11 (up Titration). The experiments were conducted with a laboratory titrator and the buffer capacity profiles were processed by Fitting mathematical models of buffer systems to them.
