I disagree! Most activated sludge plants in Europe and the Middle East (where I've gained my 26 years' experience) operate without balancing or equalisation tanks. They are, however, used on perhaps half of the AS plants in S Africa. Equalisation tanks do allow savings in the AS plant size, but the penalty is another tank to operate and maintain, and often an additional pumping stage.
