Abstract

Research into bulking in laboratory‐scale activated‐sludge plants are reported upon. A correlation between sludge volume index (SVI) and biopolymer content (exocellular polymer, ECP) has been determined or sludge obtained under various operating conditions and with different chemical and physical characteristics. This paper interprets that correlation. A method for ECP determination that is quicker and just as precise as the gravimetric one and which enables this parameter to be used not only to interpret bioflocculation mechanisms but also as a parameter for evaluating optimal plant operation is reported.
