High rate trickling filters
Did you know?
WebThe normal hydraulic loading rate ranges for standard rate and high rate trickling filters are: Standard rate: 25 to 100 gpd/sq ft or 1 to 40 MGD/acre; High rate: 100 to 1000 gpd/sq ft or 4 to 40 MGD/acre . If the hydraulic loading rate for a particular trickling filter is too low, septic conditions will begin to develop.

WebTo allow for good distribution and thorough blending of the filter and secondary effluent, the system should recirculate the trickling filter effluent. High-rate Filters. High-rate filters are generally loaded at the maximum organic loading capabilities of the filter, and receive total BOD loading of 40 - 100 lb BOD/day/1000 ft 3. High-rate ... 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. The active surfaces of the filtering media are worked at the same time on the impurities present in the various stages of the purification. Under-Drainage System:
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.
