Abstract

A modular block for osmotic methods of separation under pressure can be folded open and the filtration unit can easily be removed and introduced in the process. The filtration unit consists of a base plate with a membrane filter candle, and the filter candle consists of a stack of membrane filter plates. Spacers are placed between the filter plates and deflecting plates are provided to ensure zigzag penetration. The permeate transportation is displaced to the edge of the plates. The permeate issues laterally at the flange.
