The main purpose of this work is the study of the viability of a polyelectrolyte enhanced ultrafiltration (PEUF) process for the chromate recovery using poly(diallyldimethylammonium chloride) (PDADMAC) as water-soluble polymer. First of all, the interaction between PDADMAC and chromate ions was stud

In conclusion, the viability of a MEUF process for the removal of tannic acid from aqueous effluents has been demonstrated in a pilot scale plant. A clear increase in the tannic acid retention coefficient was reached when SDS was added in a concentration higher than its CMC.

A mathematical model has been developed to simulate the performance of an integrated extraction-stripping process based on the use of hollow fiber contactors. The model allows one to predict the time-dependent concentration profiles of the two phases involved in an individual extraction or stripping
