Patent ID: 8628662

Claim:
A device for filtering of liquid, in particular water, comprising membrane filtering modules which are connected by pipes to valves in order to control the flows of liquid going to and from the modules, including a first block made up of an assembly of membrane filtering modules, a second block made up of a system of valves, and a third block made up of a group of intermediate pipes constituting an interface between the system of valves and the assembly of modules, only the interface requiring to be changed when changing the types of filtering modules, whilst the system of valves and the assembly of modules, except for changing the type of modules, remain unchanged, wherein the assembly of membrane filtering modules comprises a supply collector, a first filtrate/residue collector, and a second filtrate/residue collector which are secured in a frame which is distinct from the collectors, the frame of the assembly of modules is configured to receive at least two types of modules, wherein one of the two types of modules uses the first filtrate/residue collector as a filtrate collector and the second filtrate/residue collector as a residue collector, and the other of the two types of modules uses the first filtrate/residue collector as a residue collector and the second filtrate/residue collector as a filtrate collector, and at least two groups of intermediate pipes which are associated respectively with each type of module, each being configured to be put into place in a removable manner between the assembly of modules and the system of valves, to ensure each of the first and second collectors flow to appropriate apertures in the system of valves.
