A filter press is generally an industrial tool that utilizes the principle of pressure drive to separate solids and liquids. There exists a multitude of different filter presses in the market; choosing an ideal one that is compatible with your interests can often be a challenge. It is therefore important to make some considerations before making your decision. Below are a few factors to consider. The plate size of the filter press should always be among the top factors to consider before choosing a filter press. By making the proper selection of the plate size, components, its frame, and other major components, one can easily evaluate the exact feet capacity in relation to the volumes of each independent sizes. The size to choose is always determined by the amount of space one would like to expand further. After determining the size of the filter press plate you would like to go along with, one now determined the type of material they would like their filter press plate to be made of. There exist different materials such as industrial grade polypropylene which is the standard material used in most filter press plates, there also exists a range of other various materials one can choose from. These can either be; high-temperature glass-filled polypropylene, approved food grade polypropylene, stainless steel and carbon steel among others.

There is also the plate design or style one should always consider before choosing a filter press. The standard plate style used is the hundred pounds per square inch recessed plates fitted with a gasket. One can also choose from plates with no gaskets and Viton seals. These designs usually exhibit different features. For instance, the plates with no gaskets are much cheaper compared to other designs of filter plates; they are also easier to change out of their filter clothing.

On the other hand, filter press plates that incorporate membranes into their designs have ease of allowing filter cake to be squeezed into a drier form of filter cake due to the presence of an inflatable bladder. If your desired mode of operation requires low volume, one can opt to purchase a backing plate. This accessory will enable you to reduce the capacity of a filter press temporarily. Another factor to consider before choosing a Filter Press should always be the plate and press pressure rating. For most dewatering application, the plate and press pressure rating usually used is a hundred pounds per square inch that produces approximately thirty percent solids. Depending on the yield per cycle one require, if you are right of increased value, the ideal filter press to choose would be that with a plate and press pressure rating of about two hundred and twenty-five pounds per square inch.

Depending on the material to be formed; whether it is a high viscosity slimy material or for an easily filtered material, one should always consider the cake thickness before making their decision. If your intended material is to be highly viscous, one should opt to choose a cake thickness of about twenty-five, for the following type of cake thickness which is an easily filtered material, one should consider a cake thickness of about fifty-five millimeters. These are just but a few factors to consider before choosing a Filter Press.
