ABSTRACT

Ultrafiltration, nanofiltration and reverse osmosis in series were tested in pilot plants as the proper treatment for water to be used in pharmaceutical industry, the feed being the municipal water. Ultrafiltration ensured the removal of colloid particles (lower SDI value), nanofiltration the removal of water hardness and reverse osmosis the deionization of water. The experimental data obtained from the pilot plant tests could be used as the basis for the design and performance of the industrial plant.
