Filtration of Larger Flows with Horizontal Pressure Filters

Horizontal Pressure Filters consist of a pressure vessel with an overdrain system for distribution of influent water and collection of backwash waste.

Horizontal Pressure Filters allow you to:

Maximize filtration area per footprint

Maintain system pressure through the treatment process

Eliminate backwash supply pumps

Utilize several media configurations

Features and Benefits

Features:

Enclosed filtration system
Water only or air scour backwash
Curved plate underdrain
Common underdrain system
Multiple cells in a single vessel

Benefits:

Line pressure maintained
Re-pumping after filtration eliminated
Provides most effective backwash for a specific system
Allows for easy inspection
Allows backwashing from in-service cells
Reduced backwash flow rate

Horizontal Pressure Filters operate like other pressure filters although the horizontal configuration increases filtration area per footprint. Multiple cells can be installed in a single vessel to allow operating flexibility and backwashing from in-service cells. Over 1 MGD (4 MLD), they are more economical than several vertical pressure filters.

Common applications include iron, manganese and arsenic removal from groundwater and industrial process water treatment. Vessel design and manufacturing includes non-code or ASME code with stamp for a wide range of operating pressures.
