The orientation of the filter element is the one that brings the whole difference between the horizontal leaf filters and the vertical pressure leaf filters. They are either used to filter cakes that have a solid concentration of below fifty percent and also for slurries polishing with low solids of below five percent. These vertical leaf filters are also wheel designed for handling corrosive, flammable and toxic materials. They may also be jacketed to be used for both the cold and the hot temperatures. The features may, however, be unavailable for on the filter press since it will need the plates to be open in the atmosphere and also to shift them so as to allow the cake to be easily discharged.
There are times when the vertical leaf filter is more preferred than the horizontal one. Some of the instances that you select this particular leaf filter are when you have a small floor place, and you need to make a large filtration area. The vertical pressure leaf filter does not consume as much time as the horizontal leaf filter. The other instance is when the liquids involved in the filtration process are not supposed to be subjected to the vacuum since they are volatile.
The vertical pressure leaf filters are also more preferred when there is an environmental hazard risk from the volatile toxic and flammable cakes that are most especially incorporate the secure discharge mechanisms. This is also done when it is very clear that there that there is a need of high filtrate because of the polishing applications. It is also preferred when the materials in question are saturated brines that need more high temperatures. When this is required the tank of the vertical pressure leaf filter is jacketed. Finally, it is the best option when you either need the cake as thickened or as dry slurry.
However, there are instances that you have to be more careful when using the vertical pressure leaf filter. The pressure of the vertical PLF may not be enough to hold a heavy and thick cake and thus one should be very careful on this. The recoat should always be done before the filtration any time there is a mesh screen coarse. This is done to make the cake remain with the fine particles. Percolating with quite a thin layer perlite or diatomite is a rather challenging process, and one should avoid it as much as possible.
This vertical PLF has some benefits that make prefer using it compared to the other type of the pressure leaf filter. It is said to use less operational costs, and thus it is economical to the user. It also has a compact and closed operation, and thus there is no spillage. It user-friendly and anyone with little training will be able to use it sufficiently. The vertical pressure leaf filters have a high rate of filtration and thus have an increased daily production. You will not need to use the filter cloth and thus you will not recurring expenses with this type of the pressure leaf filter.
