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.
