Maximum Available Filter Pressure Drop

automated. Some regulatory agencies, however, prefer gravity systems because the filters can be observed during filtration and backwashing.

lating in the filter media. The effluent quality is slightly better at the start of each filtration and remains relatively constant until media voids are full. Then, a sudden breakthrough of solids into the filtrate occurs. A filter is optimized when the maximum available filter pressure drop coincides in time with the breakthrough of the SS (see Figure 7.33.7).
