      Water is involved in all major industrial activities. It comes in contact with mineral or organic raw materials, it dissolves or comes with it. These are the reasons why each industrial activity generates polluting waste, often donated directly to water (factories located beside rivers to facilitate transport and other amenities). This article attempts to characterize the pollution of industrial waste through the study of its harmfulness and their effects on the environment. The history of industrial development was built in partnership with the water. Factories are still located on the edge of the water (river, canal or sea) for various reasons: - Transportation facilities for raw materials and finished products - The opportunity to carry to water many and varied industrial tasks: the entire history of industrial techniques is related to the use of water - Rejection amenities of byproducts or waste generated during manufacturing operations. The water brings a unique set of physical and chemical properties it can become solvent, thermal fluid or just easy to handle liquid. These properties explain why water is involved in all major industrial activities factories use water repeatedly during successive stages of the manufacturing line. For most technical and manufacturing operations, the water comes into contact with inorganic or organic raw materials. It dissolves the partially or completely or causes them to the state of colloidal suspensions. Using the water is practically "accept polluting it" ... In fact, all industrial activity generates polluting discharges that contain all the by-products and raw material losses that could not be recovered or recycled, and the big problem is when Industrial wastewater discharged into the Mediterranean Sea ,it gives an ecological disaster as the ecological disaster that affects the Bay of Bousmail . This bay undergoes 11 domestic wastewater discharges and two industrial water spills, rejected by both industrial areas Chaiba and Bousmail, which constitutes a real danger to the environment and the sea. For several months the shore of the city of Bousmail is invaded by unbearable and nauseating odors that come from sea water which is oddly colored. The rocks have lost their original color and has turned white. The sea is heavily polluted due to wastewater from food industries and paper mills installed on the heights of the city in the absence of wastewater treatment. Maritime school students in this area have collected black urchins inside, especially genetically modified and condemned to no longer REPRODUCED and the disappearance of octopus and other marine species because of this ecological disaster. |
