VALORIZATION OF BIO-PLASTIC (PHA) FROM WASTEWATER AND CIRCULAR ECONOMY
ABSTRACT Circular economy requires sustainable supply of raw materials to industries. Social and economic networks are needed in order to develop circular economies that would drive value chains in renewable resource processing from wastewater into renewable bioplastic products. Current plastic is non-biodegraded which can cause harm to our environment. A pilot scale investigation was carried-out so as to evaluate the feasibility of producing value-added bioplastic from wastewater treatme...
PLANT DESIGN OF 250,000KG/YR OF LINDANE
EXECUTIVE SUMMARY This work presents the design of a plant that will produce 250000kg/yr of lindane from benzene, chlorine and water at high temperature and pressure using direct chlorination method. The feeds are sent into a chlorinator, the crude product from the chlorinator is continuously decanted into a decanter and the bottom product HCl i...
EFFECT OF LYE SOURCE ON THE KINETICS AND QUALITY OF LOCAL SOAP
This research presents the effect of lye on the kinetics and quality of local soaps. To achieve this, 40ml of 10 percent lye (palm bunch, coconut shell and synthetic sodium hydroxide) reacted with 60ml of oil (palm oil and palm kernel oil) in a batch system, under conditions as, constant temperature (50 degree celcius) and constant stirring (100 rpm). Variation in saponification value and free fatty acid was monitored with time, that is, at intervals of 2mins. It was noticed that as time incr...
QUALITY CONTROL FOR WASTEWATER TREATMENT
Quality control is a checking test to monitor and ensure the wastewater treatment plant (WWTP) is at optimum efficiency. The tests are usually carried out on samples collected from specific points or stations in the WWTP. The Influent sample, is collected after the fine screens. Aeration basin sludge, iscollected from the point of overflow of the aeration basin, before it is sent to the clarifier. Return Activated Sludge (RAS) sample, is collected from the sludge pumping station. Waste Ac...
WASTEWATER TREATMENT PROCESS AND TECHNOLOGY
Wastewater is made up largely of organic carbon, either in solution or as particulate matter. About 60% is in particulate form, consisting of proteins, amino acids, peptides, carbohydrate, fats and fatty acids. Wastewater treatment plant (WWTP) prevent potential waterborne disease outbreak. This is achieved by the active use of mechanical process and biological process of the treatment plant to treat and convert wastewater into clear effluent that meets specific standard. The effluent water...
