Plate and frame filter plates are the oldest filter plate design. The chamber is formed by a flat plate on each side of a frame. Plate and frame filter plate is normally used in application where filtration area is more important than volume.
The Membrane Filter Press is an advanced filtration system designed for industries that require superior dewatering performance and reduced moisture content in filter cakes. Unlike conventional chamber filter presses, this machine uses membrane plates that can expand after the filtration cycle to apply extra pressure, squeezing additional water from the cake.
This technology ensures:
Higher dryness of solids.
Shorter filtration cycle time.
Reduced handling and disposal costs.
Dazhang Membrane Filter Press is widely used in chemical, pharmaceutical, food & beverage, mining, wastewater treatment, metallurgy, paper, and textile industries due to its durability, efficiency, and ability to handle both fine and coarse slurries.
The process consists of two main stages:
Slurry (liquid-solid mixture) is pumped into the chambers between filter plates.
The filter cloth captures solids, forming a filter cake.
The filtrate (clean liquid) passes through the cloth and drains out of the system.
Once chambers are full, the membrane plates are inflated using compressed air or water.
The membranes expand uniformly, applying extra pressure on the filter cake.
Additional water is expelled from the cake, reducing its moisture content by up to 20–30% compared to standard filter presses.
Finally, the plates open, and the drier, compact filter cakes are discharged, ready for disposal or reuse.
Time Savings: Faster cycle times compared to conventional filter presses.
