It is possible to benefit from continuous belt filtration at higher pressures by placing the filter in a pressurised housing However such devices need a form of gas lock to ensure that the vessel can remain pressurised while the cake can be discharged to atmospheric pressure One way to achieve this is to use a rotary valve see Figure 10 However this can result in the loss of some of
The location of the pressure filters often exposes the housings to continuous pressure stresses that can reach high values The filter development is done with a 3 Dimentional CAD system that utilizes computer simulations to develop stress calculations These calculations are used to support the most appropiate choice of the materials and of the internal profiles of the castings to withstand
