Problems solved by technology

Another disadvantage is that no filtrate can be produced during back flushing due to the use of the same line
However, this method only works in the case where there are multiple units that proceed one after the other

Embodiment Construction

[0016] An embodiment of the invention is explained in more detail below with the sole figure showing a schematic flow diagram of a filter system according to the invention.

[0017] The shown filtration system 1 is an ultrafiltration system comprising a plurality of filtration modules 2 each comprising a bundle of hollow fibers through which filtration is performed through the walls of the hollow fibers. Throughout the system, the filter modules 2 are substantially identical and perform the same functions. The filter modules 2 are combined into groups 2A, 2B, 2C, 2D, 2E and 2F. Each of the groups 2A-2F preferably comprises the same number of filter modules 2, whereby, in the embodiment shown, 3 filter modules 2 are provided for each of the groups 2A-2F. However, the number of filter modules can vary according to requirements, and in extreme cases, each group can also comprise only one filter module.

[0018] The water to be treated is supplied to the filter module 2 via line...

Abstract

The method for ultrafiltration of water using individual filtration modules, comprises supplying water over a raw water inlet from a raw water outlet and removing the filtrate of the water towards a filtrate outlet. The filtration modules are cleaned by backwash with the filtrate and are divided in groups. During backwashing of each group, individual filtration module is separated from the raw water supply and is produced with the groups during backwashing and the recirculated filtrate is flushed.

Description

technical field [0001] The present invention relates to a water filtration method, in particular an ultrafiltration method, which utilizes a plurality of independent filtration modules to filter water, and supplies each filtration module with water to be treated from a water supply line to be treated via at least one water inlet to be treated. Treating water, removing filtrate from each filtration module via a filtrate outlet, the invention also relates to a filtration system, in particular an ultrafiltration system, with a backwashing device for backwashing with filtrate and a plurality of independent Filtration modules each having at least one treated water inlet connected to the treated water circuit and one filtrate outlet connected to the filtrate collection circuit. Background technique [0002] Currently, ultrafiltration systems are constructed in various forms, however filtration methods are generally carried out in a similar manner, i.e. the resulting filtrate (as f...
