Selection Guide for Horizontal Plate Filters

The cake filtration process is more economical to operate than bag or cartridge filters when filter aids are required to meet clarity specifications and achieve process flow rates. The capability to wash and dry the filter cake maximizes product recovery and minimizes operator exposure.

For high process flow rates, horizontal plate filters have the highest surface area to tank volume ratio of any filter design. Intermittent operation is possible and cake stability is assured with the plates in the horizontal position. Continuous operation is possible with two filters, one online and one off-line for cleaning and standby.

HPF Horizontal Plate Filter

The HPF horizontal plate filter has a vertical tank with horizontal stacking plates and tie rod compression. Flow is into the tank, across the filter plates, through the media, and down the center column with a bottom filtrate outlet.

RF Reverse Flow Horizontal Plate Filter

The RF reverse flow horizontal plate filter is a vertical tank, horizontal plate filter, with tie rod compression and a flow path the reverse of the standard HPF. Flow is up the center column, across the plates, thrrough the media, and into the tank.. With only clean filtrate in the tank, cleaning is simplified. Solids are completely contained within the filter plates and settling problems are eliminated. Less gas is required for blowdown and drying.

VR Horizontal Plate Filter

The VR filter is a horizontal plate filter design for using paper media on the top and bottom of the plate. This trap filter design gives double the surface area for high flow rates with low solids. If flow stops, the cake can drop from the bottom of the filter plate.

V Horizontal Plate Filter

The V filter has a dual V design horizontal plate with either welded wire mesh media or cloth bags to cover both sides of the plate.

Like the VR, the V design has twice the surface area of a standard HPF for high flow rates with low solids. Flow needs to be continuous to avoid dropping the cake on the bottom side of the plate.

WO Wash-Off Horizontal Plate Filter

The WO is a wash-off horizontal plate filter where the filter plates pull as a unit from the tank and do not require disassembly for hosing off the cake outside the tank. Either welded wire mesh or cloth bag media is used.

WOT Wash-Off Tilt Horizontal Plate Filter

The WOT or wash-off tilt filter has an internal sluice header and tilts from the vertical tank position to the horizontal for washing-off cake without opening the tank.

HRC Horizontal Plate Filter with Rotating Plate Cartridge

The HRC is a horizontal plate filter with a rotating plate carriage in a horizontal tank. The plates are horizontal for filtration and rotate to the vertical position for automatic dry cake discharge with a vibrator and internal screw conveyor.

HRS Horizontal Plate Filter with Rotating Plate Cartridge and Sluice Header

The HRS is a horizontal plate filter with a rotating plate carriage and an internal sluice header for wet cake discharge through a drain. The HRS filter does not have an internal screw conveyor, so the filter tank volume is smaller.
