Filter Press - advantages and applications

Filter Press is a batch processing pressure filter used for its high separation efficiency and simple working mechanism. The design of this popular processing equipment has significantly evolved over the decades to further improve the filtration safety and efficiency. One of the major design improvement areas has been automation of cake discharge and washing of filter media to enhance the filtration effectiveness and efficiency.

Below schematic illustrates the working mechanism of a typical filter press.

Advantages of using a filter press are:

• Separation efficiency
• Ease of use
• Efficient dewatering of fine solids
• Can achieve very low cake moisture content
• high processing capacity
• Minimal energy consumption
• Long service life

However, there are some disadvantages to using a filter press, such as:

• Common designs are built for batch processing
• High noise levels
• Frequent chemical conditioning or pre-treatment is required to capture solids effectively

The main industry applications of filter press are as follows:

• Food and beverage – wine, beer, juice,
• Wastewater treatment – dewatering waste and sludges, assists with Dissolved Air Flotation “DAF” process
• Water treatment – dewatering lime-softening sludge
• Mineral Processing – ceramic industry, stone and sand washing plants, marble and granite, copper, zinc, and lead concentrates
• Chemical – treating dyes-stuff, brines, resins to phosphates and much more
• Industrial – concrete and wastepaper washout water recovery, small scale wastewater treatment of paint and galvanising industries
• Pharmaceutical – applications where significant reduction in moisture and a finer filtration is required
