Industrial Multi-Media Water Filter Sizing Calculator

There are multiple variables in sizing industrial water multi-media filters that are beyond the scope of the multi-media filter calculator below. Examples include water pressure, temperature, flow rate, available foot print and cubic feet of media per tank. Therefore, these industrial ML filter guides should only be used for quick estimates.

Vertical Pressure Filters - WesTech Engineering, Inc

Vertical pressure filters provide granular media treatment in an enclosed pressure vessel. Multiple vessels can be used to allow operating flexibility and backwashing from in-service cells. Under 1 MGD (4 MLD), they are more economical than horizontal pressure filters. Vertical pressure filters are typically applied in small to medium sized plants.
