PREPARATION FOR THE DISPOSAL OF URINE AND/OR OTHER VETERINARY EMPLOYMENT PRODUCTS FROM BLOOD VETERINARY OR BLOOD VETERINARY MEDICINAL PRODUCTS

摘要

Method for extracting urea from blood washing effluents or from blood liquids, whereby the liquids are treated with a solid organic material which is then separated therefrom, said method utilizing as organic material at least a compound which comprises at least an aldehyd group per molecule, in which the aldehyd groups are activated or masked at the intramolecular or intermolecular scale by a substituant bearing a proton, i.e., as applicable, -COOH, -CHO or -SOu3uH. The method is applicable to dialysis or ultrafiltration with semi-permeable membranes and allows a rapid and significant elimination of urea, while using a relatively small amount of organic material, without producing harmful substances.
