Dewatering Pressure Filter

Verti-Press — Pressure Filter

Could a Verti-Press pressure filter (filter press) be your ideal solution for filtering, washing, and dewatering slurries or products?  

This high-pressure vertical tower filter press easily removes your solids by passing fluid through a filtration membrane using precise pressure.

And, these pressure filters can be stacked vertically saving you space because they have a relatively small footprint compared to a conventional plate and frame filter.

Description

The Verti-Press pressure filters are designed to be 100% automatic with minimal operator attention required.

All process variables are monitored and displayed on the control panel’s HMI touch screen which also acts as an operator interface.

Each filter cake is discharged from the filter at one end simultaneously eliminating the need for cross conveyors and lowers installation costs.

And, each filter chamber has an independent conveyor, a dedicated filter belt and a prox switch to insure all filter cakes are completely discharged each cycle.

The Verti-press can also be configured with individual chamber isolation, getting you higher equipment availability by providing you with far greater flexibility when planning for maintenance.

The vertical pressure filter chamber design also minimizes potential chemical exposure outside of the tower filter press, ensuring operator and equipment safety. 

In short, when high cake solids and higher wash efficiency are required, along with reliability and maintainability, you'll find the Verti-Press automatic filter press technology a wise investment or equipment rental.

Operation

  • 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.

Features and Benefits

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.)
