Undoubtedly, agri-food industries are the world’s largest consumers of good quality water, especially the different processing of sea food products [1]. Water is an essential and necessary vector in the processing operations of fish industries (washing, preparation of sauces, ice production, etc). During this time, the liquid flows from these industries present major pollution problems if not treated. The main objective of the experiment reported in this paper is to investigate wastewater quality of El Marsa Laayoune industrial area, in order to find an evolutionary mechanism that will allow a good water management in industrial units, and help to improve effective treatment solutions. The physicochemical characteristics of the polluted waters are determined by the analysis of several parameters like pH, temperature, conductivity, turbidity, dissolved O₂(DO) COD and others. The results show that the load pollutants are essentially organic. The decantable material (DM) rate exhibits a sediment load. The ratios COD/BOD₅, BOD₅/COD and VMS/SM (SM: suspended matter) confirm this deduction and reveal considerable biodegradability. There are also very high levels of chlorides.
