Abstract: A grid and a vat for a vat assembly of a vertical filter press such as a tower press is disclosed. The grid is provided with a topographical pattern engaging with a corresponding, inverse topographical pattern on the filtrate vat. The topographical patterns guide the filtrate flow towards a filtrate outlet and reduces the formation of vortices and turbulent flow of the filtrate, hence increasing the filtrate flow rate through the vat. Simultaneous, the topographical patterns improve secure attachment of the grid onto the vat, thereby allowing increased travel speed of the filter medium during advancement thereof. As a result, the cycle time of a filtration process may be reduced, and consequently, the overall capacity of the associated filter press is increased. A filtrate vat assembly and a vertical filter are also disclosed.
