Filter for liquid, in particular water, consisting of at least two substantially equal elements (1-4) arranged side by side and assembled to one entirety, each being in form of a rectangular parallelepiped with flat rectangular walls, whereby the inlet tubes (1e, 1f) or outlet tubes (1g) are extending horizontally through the front or rear wall of each element and tubes of all elements (1-4) lying in one or more horizontal planes are connected outside of the elements (1-4) to one or more horizontal distribution or collecting conduct(s) (7,8,9) extending along all or a number of the elements (1-4), said filter is formed as a pressure filter, whereby the housing of each element (1-4) consists of flat rectangular front and rear walls and flat rectangular upper and bottom walls, the adjacent edges of the corresponding walls of adjacent elements (1-4) are connected to each other pressure-tight and rigidly and only the first and final element (1,4) being closed by flat rectangular end walls and whereby each element (1- 4) separately is reinforced by external and/or internal means (1,2).
A filter for liquid comprising a plurality of substantially equal volume elements arranged side by side and assembled together, each being in the form of a totally closed rectangular parallelepiped pressure tight housing with flat rectangular front, rear, upper and bottom walls and containing filter material, and having a set of inlet tubes connected by header means outside said filter and a set of outlet tubes connected by header means outside said filter, said inlet and outlet tubes extending horizontally through front or rear walls of each element, means connecting the housings of adjacent filter elements to each other, and means reinforcing walls of each element separately against internal outwardly acting pressure from liquid supplied under pressure to the element through said inlet tubes.
