Resum: The availability of a reliable and clean supply of water is one of the most important determinants of our health. On the other hand, 1.8 billion people are expected to be living in countries or regions with absolute water scarcity, and two-thirds of the world population could be under water stress conditions by 2025. Thus, different practical solutions are needed for sustainable protection of available water resources. Industry consumes about a quarter of all water comsumption and much of the water used by industry is generally taken from public water supplies. Currently, membrane technologies in wastewater treatment become important because of the the need for water recovery and reuse by industry. Membrane processes can produce water with reliably high quality.

In this conference, some field tests results using pilot-scale nanofiltration (NF) and reverse osmosis (RO) processes for desalination of wastewater treated by membrane bioreactor (MBR) process in a wastewater treatment plant of an industrial zone will be discussed. Electrodialysis (ED) method having ion exchange membranes was applied for solving the concentrate problem limiting applicability of pressure driven membrane processes. In addition, electrodeionization (EDI) method combining ion exchange membranes with ion exchange resins was employed for post-treatment of permeate stream of RO process. The qualities of product water obtained were evaluated according to the quality standards required by various industries.
