MEMBRANE FILTER AND METHOD FOR PRODUCING A MEMBRANE FILTER

A membrane filter for filtering a liquid by submerged operation, the membrane filter comprising membrane elements arranged horizontally adjacent to one another and including headers, each membrane element including membranes arranged in a vertical longitudinal direction and filtering a liquid permeate from the liquid, a header of the headers that is arranged at a uniform header level and includes a permeate collection cavity, wherein the membranes are connected at a permeate side of the permeate collection cavity, a permeate outlet draining the liquid permeate in an outlet direction horizontally from the permeate collection cavity, and a tube connected at a top of the header and laterally enveloping the membranes of the membrane element, wherein the permeate outlet of each of the membrane elements is connected at a horizontally extending common permeate collector that drains the liquid permeate from the membrane filter.
