Tag: Non-dispersible Solids

Introduction In the realm of municipal wastewater treatment, the handling of thickened sludge, scum, and septage presents a persistent challenge: the increasing prevalence of non-dispersible solids. While engineers frequently turn to positive displacement technologies for these viscous fluids, Double Disc Pump Clogging and Ragging: How to Reduce Blockages remains a critical operational concern. Despite being […]

Introduction The escalation of non-dispersible solids in modern wastewater—primarily synthetic wipes, rags, and fibrous materials—has fundamentally changed the operational baseline for municipal lift stations and treatment plants. Engineers are increasingly forced to move beyond simple solid-handling pumps to aggressive solids reduction strategies. A critical decision point in this defense strategy is the selection of Wilo […]
