Abstract:
1. Membrane module for substance-specific treatment of a fluid, comprising a housing, an inlet arrangement for feeding the fluid to be treated into a distribution space in the housing, an outlet arrangement for removing the treated fluid from the housing via a collection space, and first membrane elements arranged in the housing and having a first porous, semipermeable wall, each having one end pointing toward the distribution space and the other end toward the collection space and at least one or more first cavities formed by the first porous, semipermeable wall, wherein the first membrane elements are embedded in a first sealing compound at the end pointing toward the distribution space and in a second sealing compound at the end pointing toward the collection space, such that the ends extend through the first and second sealing compounds and each of the first cavities of the first membrane elements is open at the end pointing toward the distribution space as well as at the end pointing toward the collection space and opens into the distribution space and collection space, wherein the membrane module also comprises second membrane elements arranged in the housing and having a second porous, semipermeable wall, one end of the second membrane elements pointing toward the distribution space and the other end toward the collection space, and at least one or more second cavities formed by the second porous, semipermeable wall, wherein the second membrane elements, at the end pointing toward the collection space, are embedded, along with the first membrane elements, in the second sealing compound such that these ends extend through the second sealing compound, and each of the second cavities of the second membrane elements is open at this end and opens into the collection space, and the second membrane elements are closed at the end pointing toward the distribution space, the first and second membrane elements forming a membrane-element arrangement, and an outer space being formed between the sealing compounds that is partitioned in a fluid-tight manner from the distribution space and the collection space and delimited by the sealing compounds, the inner waif of the housing, and the membrane elements.
