Natural organic matter in aquatic environments can form carcinogenic organochlorine
compounds when is chlorinated. On the other hand, the lack of water in the southeast of
Spain is the main reason to study new alternatives of purification techniques and their
optimisation. As a consequence, it will improve the use of natural waters.
The objective of this work is to study the removal of humic acids by means of an
ultrafiltration system using cationic and anionic membranes of poliacrylonitrile (50 kDa
MWCO), and analyze effects of pressure, conductivity and pH.
In the current paper three different waters were tested, humic acid (HA) solutions from
Aldrich Chemical Co., water of Amadorio swamp and water of Pedrera swamp. These
superficial water are situated in southeast of Spain, in the province of Alicante.This study was financial supported by the “Plan Nacional de I+D 2004-2007” of the Spanish Government (Ref. CTM2004-03056, Spain) and by a grant from the Joan Gil-Albert Foundation
