METHOD AND DEVICE FOR PROCESSING WATER BEFORE MIXING IT WITH PHYTOSANITARY TREATMENT PRODUCT

摘要

The invention relates to a method for the preparation before spraying of a phytosanitary treatment product, that comprises the following steps: processing the water for partially or totally removing at least one of the following cations Ca²⁺, Mg²⁺, Mn²⁺, Al³⁺, Zn²⁺, Fe²⁺, Fe³⁺, whose presence my alter the efficiency of said phytosanitary product, using a demineralisation bed formed by associating a cationic ion exchange resin and at least one zeolite in a proportion of 80 % of ion exchange resin to 20 % of zeolite; and mixing the phytosanitary treatment product and the processed water, essentially from a bore, a well or a spring. The invention also relates to a water processing device for implementing said method, comprising demineralisation means in the form of a demineralisation bed formed by associating a cationic ion exchange resin and at least one zeolite in the respective proportions of 80 % and 20 %.
