Abstract This investigation was undertaken with the objectives of reviewing the conversion of trickling filters at the Stockton, California, Regional Wastewater Control Facility from rock media to plastic media and to develop general design considerations for similar conversions which might be carried out elsewhere. The Stockton plastic media trickling filters are designed to operate in two modes: (1) to oxidize carbonaceous material during the canning season when plant loadings are high (design flow = 220,000 cu/day or 58 mgd) and, (2) to provide combined carbon oxidation-nitrification during the noncanning season when loadings are low. To evaluate plant performance, a special 1-yr sampling program was carried out.
