Abstract (en)
[origin: WO2022177425A1] A method is presented for reducing sodium content of cultivation water for plants. This method comprising the steps of: contacting cultivation water with a cation exchange resin configured to capture at least sodium ions, resulting in an effluent C; contacting an 5 aqueous solution S with the cation exchange resin to remove sodium ions from the cation exchange resin, resulting in an effluent S comprising sodium ions, the aqueous solution S comprising cations not being sodium ions and anions soluble in water with the cations; discharging the effluent S; contacting an aqueous solution R with the cation exchange resin to regenerate the cation exchange resin, resulting in an effluent R, the aqueous 10 solution R comprising an acid; and recirculating at least one of the effluent C and the effluent R for use for plants. Further, an apparatus suitable for implementing said method is presented as well as a cultivation system for plants comprising said apparatus.
