Verti-Press — Pressure Filter

• Using intelligent process controls, the slurry is fed into the filter while being monitored for the optimal cake height. 
• Once optimal cake height is reached, a diaphragm mechanically squeezes the filter bed, releasing the liquid but not smash the solids.
• The diaphragm squeeze produces filter cakes as dry as 94% solids.
• The cake can then be washed clean, dewatered again, and finally dried by using an air blow sequence. 
• The dry cake is then discharged.  

With four filter size options and the capability to add filter modules, the Verti-press covers a wide range of capabilities and applications. 

EXTREMELY DRY CAKES
The diaphragm squeezing can produce cakes as dry as 94% solids. This process is 5-50% drier than conventional vacuum filtration, plate and frame filters or belt presses.

HIGH SPEED CYCLING
The Verti-Press filter press can cycle as fast as five minutes - discharge to discharge. Fast cycles mean dramatically increased output per machine.

FULLY AUTOMATED
The filter cakes are carried from the filter chamber by a fiber belt. This ensures that the cakes are positively discharged from the filter at every cycle. All phases of the filter function are controlled by a programmable controller to eliminate the need for a full-time operator and to minimize operating costs.

VERTICAL DESIGN
Vertical stacking of the horizontal automatic filter press chambers allows for maximum use of your plant space and leads to improved cake washing efficiency. Horizontal positioning of the filter cakes ensures uniformity, constant thickness, homogeneous structure and equal flow resistance. All of these factors lead to highly efficient cake washing and minimum wash water consumption.

SINGLE POINT CAKE DISCHARGE
All of the conveyors discharge the filter cakes at one location. This greatly simplifies the cake handling requirement and allows for simpler and lower cost filter installations.

ENERGY EFFICIENT DESIGN
Filter sealing, diaphragm squeezing and retraction are done hydraulically using water as an operating fluid to minimize energy consumption. The use of costly compressed air is minimized or eliminated completely.

SIMPLIFIED DESIGN
Unlike conventional pressure filters, which require complex mechanisms to open and close the filter plates, the Verti-Press filter press has few moving parts. The filter chambers are stationary - filter sealing is accomplished simply by pressurizing the seals on each end of the filter chamber. The only other moving parts in the filter are the diaphragm and the filter belts. All filter belts are individual and can be changed in 10 minutes or less without the need for special tools.

MINIMUM INSTALLATION COST
All filters are delivered fully assembled, pressure tested and ready for startup. No special foundations are required, reducing installation time and cost.

EFFICIENT BELT CLEANING
The Verti-Press filter press comes with an efficient belt washing system as a standard feature. All belts can be washed at each cycle, leading to longer belt life and reduced maintenance costs.

HIGHEST CAKE WASH EFFICIENCY
Because of its unique chamber design and horizontal filter chambers, the Verti-Press filter press can achieve 99% + wash efficiencies while utilizing very little wash water (typically only 3 wash displacements.)
