The major advantages of dual-media filtration are higher rates and longer runs. Anthracite/sand/garnet beds have operated at normal rates of approximately 5 gpm/ft² and peak rates as high as 8 gpm/ft² without loss of effluent quality. CAPPING OF SAND FILTERS. Rapid sand filters can be converted for mixed media operation to increase capacity ...

Filter bag replacement can be one of the largest operating expenses for a baghouse system. Selecting a filter media on price alone can be costly. A low priced media with short bag life could actually be more expensive over the lifetime of a system. Analysis of filter bag failures often reveals system problems that are easy to correct.

The improvement of filter media design (i.e. number of pores) showed an impact on the performance when filter media with comparable pore size are analyzed and used in the field. This variables and performance influences are shown in this paper to make it obvious that filter media design and selection have an impact on the filtration process. 0 ...

1.9.1 Dual-Media Filters. The dual-media filter, consisting of a layer of coarse anthracite coal above a layer of fine sand, is one technique for increasing the pore volume of a filter. Figure 7(b) shows the grain and pore size in a dual-media filter, and Figure 7(a) shows these characteristics for a single-medium filter.

Filtration can be compared to a sieve or micro-strainer that traps suspended material between the grains of filter media. However, since most suspended particles can easily pass through the spaces between grains of the filter media, straining is the least important process in filtration.

Filters must be sealed well to give the expected performance. Ensure the airflow passes through the filter and not around it due to leaks. The HVAC fans must be operating for the filters to clean the air. Run the HVAC system as much as practical. Some filters have charged media to increase particle removal with lower pressure drop.
