Design of Trickling Filters | Sewage Treatment | Sanitary Engineering

In this article we will discuss about the design of trickling filters. Organic Loading Rate: Organic loading rate and the recirculation ratio are the main considerations in the design, where the organic loading rate is decided; the required filter volume is calculated. Now the depth and surface area of the filter are suitably chosen to secure hydraulic loading rates within [...]
