摘要
process for treating an aqueous solution, and installation for treating an aqueous solution. A process and installation for the treatment of an aqueous solution containing substantial concentrations of a variety of contaminants, including solids, semisolids, colloids, complexes, oligomers, polyvalent, organic and monovalent, and which tends to form scale gels and precipitates at their concentration levels. are increased during treatment of the aqueous solution, the process comprising the steps of: a) feeding the aqueous solution to an ultrafiltration (uf) facility and recovering from a reduced uf permeate in such suspended solids, semisolids and colloids; b) feeding the uf permeatode obtained from step (a) to a nanofiltration (nf) plant and recovering from a reduced nf permeate in such complexes, polyvalent and organic oligomers and alimetation of the nf permeates obtained from (b) a first reverse osmosis (ro) installation and recovery from a reduced ro permeate in such monovalents. The process and plant can be used to treat process water from wet process acid phosphate production.
