Notes

The effect of selected nonionic surfactants Cirrasol FP, Cirrasol SF 200 and Cirrasol TCS on activated sludge organisms purifying wastes from the polyestre fibre industry was studied. The toxic effect of the mentioned surfactants towards bacteria, protozoa, rotifera and nematoda occurred at loads exceeding 0.32 mg surfactant/mg d.w./day and in periods of large fluctuations of the employed loads. Morphological changes of activated sludge flocs are also observed in similar conditions.
