An Introduction to Trickling Filter Wastewater Treatment Plants

J. Paul Guyer, P.E., R.A., Fellow ASCE, Fellow AEI

This course provides an introduction to trickling filter wastewater treatment plants. Trickling filter plants have been justified by their low initial cost, low operating and maintenance costs, and relative simplicity of operation. Although the effluent from trickling filter plants of earlier design was of poorer quality than that from activated sludge plants, the performance of trickling filters designed more recently is comparable to that of activated sludge plants. Both processes offer certain advantages, with trickling filters providing good performance with minimal operator care and few, if any, energy requirements.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
