In conventional activated sludge (CAS) plants that rely on sedimentation, turndown (the effective operating range) is often very limited.
"When flowing the hydrants , this sometimes causes sediment to move around in the water lines," Langwell said.
Unlike fish, stream insects cannot move around much so they are less able to escape the effects of sediment and other pollutants that diminish water quality.
