Water is used in most process industries for a wide range of applications. Processes and systems using water today are being subjected to increasingly stringent environmental regulations on effluents and there is growing demand for fresh water. These changes have increased the need for better water management and wastewater minimisation. In Morocco, water use in the food and drink industry is extensive at approximately 24 million m3 per year including 14% of drinking water in 1994. This study was conducted in a carbonate soft drink industry plant, during two years, 2001 and 2002. We have investigated the state of consumption and use of fresh water and the generation of the effluent in the factory. The aim of the study is to identify potential opportunities for reducing fresh water intake and minimising wastewater production by studying the posibility of reuse, recycling and treatment.
