Horizontal Pressure Leaf Filter Systems

Horizontal Pressure Leaf Filter Systems

The amafilter® horizontal pressure leaf filters have been specifically designed to provide a large filtration area which is the directly result of the shape of its filter leaf elements. The horizontal pressure leaf filter system produces high filtrate clarity after the clarification run. Different types of filter aids can be used in our pressure leaf filters to improve filtrate quality.

BENEFITS
• Proven technology.
• Fully automated, ensures safety.
• Small footprint required, maximized space.
• Easy access to the filter leaves for removal of the cake
• Full automation means limited maintenance and lower operational costs.
• A closed filtration system for complete safety when in use.
• Short regeneration time between filtration cycles, reducing operating costs as the filter can filtrate for longer periods without disruptions.
• Easy to clean pressure filter leaves.
• No rotating parts, keeping maintenance to minimum.
• Reinforced pressure filter leaves provide extended lifetime.
• Specifically designed self sealing cover gaskets for a perfect sealing solution and maximum safety.

Horizontal pressure filter leaf system for dry and wet cake discharge

The Horizontal pressure leaf filter systems with dry cake discharge are used in a number of applications such as filtration of sugar, cocoa or edible oils, for the removal of activated carbon, molten sulphur filtration or catalyst recovery. This system produces minimal product waste and for some applications the residual product content in the filter cake can be reduced up to 20%. When the cake is the desired product instead of the liquid and the customer wishes the cake to be as pure as possible then washing of the filter cake is an option.

The filter cake is discharged by a pneumatic vibrator through a butterfly valve located at the bottom of the filter which has been specifically designed for easy cake discharge.

The filter cake is normally dried with compressed air, inert gas or steam before the discharge.

In the amafilter® horizontal pressure leaf system the complete set of filter leaves can be moved outside the filter tank with an electric or a hydraulic system before cake discharge.

Whilst the cake is being discharged, the horizontal pressure leaf filter system is fully opened. This allows to:

  • easily assess the condition of the cake
  • ensure that the cake is fully released from the filter leaves
  • check the condition of the pressure filter leaves after cake discharge


Pressure leaf filter systems with wet cake discharge are perfectly suitable for applications where:

  • the cake formation is too low for dry discharge
  • the disposal is cheap (regeneration for wet discharge is shorter)
  • the cake/slurry needs to be transportable via a pump

Special oscillating high impact jet headers sluice the filter cake from the filter elements. Filter cloth with low micron ratings can be used for wet discharge. This ensures clear filtrate from the start. The cake is sluiced through the discharge outlet.

Amafilter® cake breakers are developed to help improve cake discharge. A cake breaker assists a properly separating compact cake to break into smaller pieces. Cake breakers are an efficient solution in ensuring the complete discharge of cake of the filter.
