The performance of the trickling filter/solids contact (TF/SC) process at high organic loadings was studied at the Morro Bay-Cayucos treatment plant. The average secondary effluent TSS increased only slightly (from 13 mg/L to 15 mg/L) when the filter BOD5 loading was doubled from 480 g/cu m-day (30 ppd/1000 cu ft) to 960 g/cu m-days (60 ppd/1000 cu ft). The rock trickling filter operated without noticeable odors at the higher loading, although Beggiatoa presence indicated the filter was stressed. When the Morro Bay-Cayucos secondary process operated in the trickling filter mode at the lower filter loading, average secondary effluent TSS was 28 mg/L. Work at the Coeur d'Alene, Idaho, trickling filter plant showed that average secondary effluent TSS decreased from 25 mg/L to 16 mg/L when the old shallow secondary clarifier was replaced with a new flocculator-clarifier.
