Webyield less solids than higher rate filters. Secondary qualityeffluent is readily achievable if the low-rate trickling filter designincorporates filter media with bioflocculation capabilities or good secondary clarification. Intermediate-rate filters Intermediate rate filters can be loaded up to 64 kg BOD 5/100 m 3-d (40 lb BOD 5/1000cu ft/day). In Webtrickling filters. The results indicated that a 90% ammonium removal was achieved at a BOD 5 surface loading rate of ~2.5 g/m2/day (0.51 lb/1000sq.ft./day) for both rock and plastic media trickling filters. This study also noted an increase in nitrification performance from 67 to 87 percent when the recirculation ratio was increased from 2.7 to ...
WebThe normal hydraulic loading rate ranges for standard rate and high rate trickling filters are: Standard rate: 25 - 100 gpd/ft2 High rate: 100 - 1000 gpd/ft2 If the hydraulic loading rate … WebThe trickling filter is an aerobic treatment system that utilizes microorganisms attached to a medium to remove organic matter from wastewater. This type of system is common to a number of technologies such as rotating biological contactors and packed bed reactors (bio-towers). These systems are known as attached-growth processes.
WebIn high rate filters, the depth of tank varies from 1.0 to 1.8 metres in high rate filters and in low rate filters from 2.0 to 3.0 metres.
