A fluid purifying module including a monolithic container, a pretreatment filter, and a selectively permeable membrane treatment cartridge, respectively housed in an external cylindrical space and an internal cylindrical space of the container, communicating with each other via one or more passages in the vicinity of one axial end of the container. The external space communicates at the same end as the opposite axial end with a first connector orifice for feeding fluid to be purified to the pretreatment filter, and the internal space communicates separately, at the same end as the aforementioned axial end, with a second connector orifice for evacuating from the module a flow of permeate (purified fluid) and with a third connector orifice for evacuating from the module a flow of retentate (residual fluid).

Module for purifying a fluid, in particular water

A system comprising a fluid treatment assembly and means for feeding the assembly with fluid to be treated and receiving treated fluid, comprising a structure () on which the assembly is adapted to be removably mounted, to interengage complementary connectors thereof with each other, is characterized in that it includes cooperating functional surfaces () formed on the assembly and the structure () so that they can enter into mutual contact to immobilize the assembly against movement in translation and keep the connectors interengaged with each other when the assembly is mounted on the structure () and to allow the assembly to be released in order to remove it from the structure () by exerting on the assembly an action limited to tilting it relative to the structure () and guided by the connectors interengaged with each other.

Apparatus for the purification of water

An electrodeionization (EDI) module is formed from an anode spaced apart from a cathode, one or more waste channels formed between the electrodes and a product channel located inward of the waste channel(s). Ion permeable membranes form the boundary between the product channel and the waste channel(s). The product channel and waste channels are filled with a mixture of anionic and cationic ion exchange materials. At least the waste channel(s) and preferably the product channel as well, use either an anion bead having a relatively low affinity for the selected anion specie(s) to be retained (e.g. Type II) or it is a blend with Type I materials. Preferably, the membranes contain an ion exchange material to speed the transfer of ions across them. More preferably, the anionic membrane contains anion materials that have a relatively low affinity for the selected specie or species for retention.

Electrodeionization module

In an electrodeionization apparatus having a cathode compartment and an anode compartment for removing ions from a liquid under the influence of a voltage, the cathode compartment includes electron conductive particles such as metal particles and/or carbon particles.
