    Development of Polymeric Membranes for Oil/Water Separation

    membranes Article Development of Polymeric Membranes for Oil/Water Separation Arshad Hussain and Mohammed Al-Yaari * Chemical Engineering Department, King Faisal University, P.O. Box 380, Al-Ahsa 31982, Saudi Arabia; [email protected] * Correspondence: [email protected]; Tel.: +966-13-589-8583 Abstract: In this work, the treatment of oily wastewater was investigated using developed cellulose acetate (CA) membranes blended with Nylon 66. Membrane characterization and permeation results in terms of oil rejection and flux were compared with a commercial CA membrane. The solution casting method was used to fabricate membranes composed of CA and Nylon 66. Scanning Electron Microscopy (SEM) analysis was done to examine the surface morphology of the membrane as well as the influence of solvent on the overall structure of the developed membranes. Mechanical and thermal properties of developed blended membranes and a commercial membrane were examined by thermogravimetric analysis (TGA) and universal (tensile) testing machine (UTM). Membrane characterizations revealed that the thermal and mechanical properties of the fabricated blended membranes better than those of the commercial membrane. Membrane fluxes and rejection of oil as a function of Nylon 66 compositions and transmembrane pressure were measured. Experimental results revealed that the synthetic membrane (composed of 2% Nylon 66 and Dimethyl Sulfoxide (DMSO) as a solvent) gave a permeate flux of 33 L/m2h and an oil rejection of around 90%, whereas the commercial membrane showed a permeate flux of 22 L/m2h and an oil rejection of 70%.

    Anellotech Plas-Tcat Funding from R Plus Japan Press Release June 30

    Anellotech Secures Funds to Develop Innovative Plas-TCatTM Plastics Recycling Technology from R Plus Japan, a New Joint Venture Company launched by 12 Cross-Industry Partners within the Japanese Plastic Supply Chain Pearl River, NY, USA, (June 30, 2020) —Sustainable technology company Anellotech has announced that R Plus Japan Ltd., a new joint venture company, will invest in the development of Anellotech’s cutting-edge Plas-TCatTM technology for recycling used plastics. R Plus Japan was established by 12 cross-industry partners within the Japanese plastics supply chain. Member partners include Suntory MONOZUKURI Expert Ltd. (SME, a subsidiary of Suntory Holdings Ltd.), TOYOBO Co. Ltd., Rengo Co. Ltd., Toyo Seikan Group Holdings Ltd., J&T Recycling Corporation, Asahi Group Holdings Ltd., Iwatani Corporation, Dai Nippon Printing Co. Ltd., Toppan Printing Co. Ltd., Fuji Seal International Inc., Hokkaican Co. Ltd., Yoshino Kogyosho Co. Ltd.. Many plastic packaging materials are unable to be recycled and are instead thrown away after a single use, often landfilled, incinerated, or littered, polluting land and oceans. Unlike the existing multi-step processes which first liquefy plastic waste back into low value “synthetic oil” intermediate products, Anellotech’s Plas- TCat chemical recycling technology uses a one-step thermal-catalytic process to convert single-use plastics directly into basic chemicals such as benzene, toluene, xylenes (BTX), ethylene, and propylene, which can then be used to make new plastics. The technology’s process efficiency has the potential to significantly reduce CO2 emissions and energy consumption. Once utilized across the industry, this technology will be able to more efficiently recycle single-use plastic, one of the world’s most urgent challenges.
