How Does a Horizontal Membrane Filter Press Work?

At the heart of the horizontal membrane filter press lies a sophisticated yet elegantly simple operational principle. These presses utilize a series of filter plates arranged horizontally, each equipped with a flexible membrane. The filtration process begins when slurry is pumped into the chambers formed between these plates.

As the slurry fills the chambers, the initial filtration occurs through filter cloths lining the plates. The liquid phase, known as filtrate, passes through the cloth while solids are retained, forming a filter cake. What sets the membrane filter press apart is the next stage: once the chambers are filled, the membranes are inflated with air or hydraulic fluid, exerting additional pressure on the filter cake.

This unique membrane squeeze phase significantly enhances the dewatering process, resulting in dryer filter cakes and higher solid content. The ability to apply uniform pressure across the entire surface of the filter cake is a key advantage of the horizontal membrane design, ensuring consistent results and optimal filtration efficiency.

The membrane squeeze phase in horizontal membrane filter presses can reduce cake moisture content by up to 30% compared to traditional filter press designs, leading to substantial improvements in downstream processing and handling.
