Ein Beitrag zur Seston-Eliminierung mit Mikrosiebfiltern

The treatment of a highly eutrophic raw water is investigated by a differentiated microscopic analysis of the seston particles in three size classes, an analysis of the assimilation pigments and of the seston solids. At an average number of particles of 10⁶/ml elimination amounts to 31… 44%. The average pigment content of 124 mg/m³ chlorophyll a plus phaeopigments is reduced by 34%, the average dry matter of 14.6 mg/l being reduced by 50%.
