Particle size distribution in effluent of trickling filters and in humus tanks

摘要

Particles and aggregates from trickling filters must be eliminated from wastewater. Usully this happens through sedimentation in humus tanks. Investigations to characterize these slids by way of particle size measurements, image analysis and particle charge measurements (zeta potential) are made within the scope of Research Center for Science and Technology "Fundamentals of Aerobic biological wastewater treatment" (SFB 411).
