The invention relates to a method for treating sugar comprising: placing a coloured sugar juice in contact with an ion exchange resin so as to charge the resin with colouring agents and to collect a bleached sugar juice; regenerating the colouring-charged resin, comprising: placing the charged resin in contact with a regeneration brine comprising a chloride salt; and collecting a regeneration effluent, the regeneration effluent comprising at least three fractions A, B and C, fraction A having a higher concentration of chloride salt than fractions B and C; and recycling the regeneration effluent, comprising: nanofiltration of fraction A of the regeneration effluent in order to obtain a first permeate and a first retentate; diafiltration of the first retentate, said diafiltration comprising: dilution of the first retentate with the fraction B of the regeneration effluent; nanofiltration of the mixture in order to obtain a second permeate and a second retentate; mixing of the first permeate with the second permeate and fraction C of the regeneration effluent,

Improved processes for extracting water soluble nutrients including sugars from plants and in particular sugar cane. The plants may be washed with a wash solution. After washing, water soluble nutrient containing liquid is extracted from the plants. A diluted wash solution may be added to the crushed plants to improve the extraction of the water soluble nutrients. The wash solution may be added to the liquid collected during the extraction to improve the separation of impurities from the nutrient containing liquid. The extracted liquid may demonstrate at least one of improved purity, improved clarity, improved filtration times, improved whiteness, and improved total recovered water soluble nutrients.
