    Abstract: Specimens of duplex stainless steels 50:50 ferrite –Austenite were heat treated at 475°C for different times and pulled to failure. Fracture toughness testing was performed according to BS 7448, clip gauge, to monitor specimen displacement. In addition, the direct current potential drop (DCPD) technique was used to monitor the crack propagation. Th... Show More

    Abstract: The tannery effluent from the wet finishing stage is a complex, highly charged rejected of organic and mineral matter. It has variable characteristics over time and is not readily biodegradable. Its physicochemical treatment by adsorption on the smectitic clay of Khlédia proves to be effective. The reduction of dye, BOD, COD, heavy metals are remar... Show More

    Abstract: This review aims to highlight entropy in the Brownian motion (BM) and coagulation process background. In water treatment processes, pertinent questions relating to entropy, BM, and coagulation are often asked: Since entropy measures disorder of a system, does disorder manifest in polluted water with its stable colloids, microorganisms, molecules an...
