Filter presses are widely used in various industries such as chemical processing, mining, and wastewater treatment for solid-liquid separation purposes. The filtration process in these presses is dependent on several factors including cake thickness levels, and most importantly, pressure applied to the filter cake.

Studies have shown that the overall filtration rate in filter presses can significantly be influenced by the operating force exerted on the filter cake. Pressure is applied on the filter cake to facilitate the effective separation of liquids from solids. As a result, the filtration rate improves. This is because higher pressures result in enhanced liquid passage, which in turn allows for the efficient passage of fluid through the filter medium.

One particular study analyzed the effect of pressure on filtration rates in ceramic filters used for the separation of inorganic liquid-solid suspensions. According to the findings, higher pressures led to higher filtration rates. Whereas lower pressures led to decreased rates. This confirms that pressure plays a vital role in determining the performance of filter presses.

In general, the relationship between pressure and filtration rate can be described as follows: as the pressure increases within the filter chamber, so does the filtration rate in harmony with it. This is attributed to several factors including increased fluid flow through the filter cake. Conversely, decreasing pressure to a certain level results in a decrease in filtration rate due to decreased fluid flow.

However, research also indicates that there exists a critical pressure value towards which the rate of increase in permeability starts to decrease. This suggests that extremely high pressures could potentially cause filter medium degradation to the automatic filter press manufacturers medium or the underlying filter plate, thus leading to impeded filtration. Therefore, careful optimization of operating pressure is crucial for achieving optimal filtration rates without compromising the effectiveness of the filter press.

Ultimately, a combination of high pressure and effective filter medium design is necessary to obtain the highest possible filtration rates in filter presses. This can be achieved by understanding the complex relationship between pressure and filtration rate, as well as optimizing operational conditions to obtain optimal performance from these vital machinery.
