Activated carbon incorporation on forward osmosis membrane surface for enhanced performance Reshma Lakra, Malini Balakrishnan, Subhankar Basu Water Supply, 2022 Cellulose triacetate (CTA) is the first-generation forward osmosis (FO) membrane used for desalination. There have been a few chemical modifications of the CTA membrane surface. This has improved membrane hydrophilicity, water flux, and salt rejection compared with unmodified CTA membranes. Chitosan-containing porous materials as composites have resulted in increased pore characteristics. It has motivated the modification of the surface of the commercial CTA forward osmosis (FO) membrane by surface coating with chitosan (CS)–powdered activated carbon (AC) mix. The membrane morphology was characterized by SEM, FTIR-ATR, contact angle measurement and AFM. Operational conditions for FO such as the orientation of the membrane active layer, feed and draw solution flow rates, and type and concentration of draw salt were optimized with the original CTA membrane. The modified membrane exhibited around a two-fold increase in the water flux and reduced reverse salt flux compared with the original CTA membrane. The improved water flux was attributed to the CS-AC coating enhancing water wettability of the membrane surface and the porous AC generating additional water flow channels. Overall, the water flux of the CTA-CS-AC membrane developed in this work was superior to that of CTA and cellulose acetate (CA) membranes reported in the literature.
Sustainable Metal-Organic Framework Technologies for CO2 Capture Hira Naveed, Haleefa Shaheen, Ranjana Kumari, Reshma Lakra, Asim Laeeq Khan, Subhankar Basu Sustainable Carbon Capture Technologies and Applications, 2022 The metal-organic framework (MOF) is a relatively new class of crystalline porous materials. The concept provides a potential pathway to sustainable capture of CO2 owing to their unique structural properties: ultra-high surface areas, tuning pores, surface functionality, and stability under a variety of operating conditions. This chapter presents a systematic overview of the role of MOFs in the separation of CO2 from gaseous mixtures. The topics covered range from the significant progress in the design and synthesis of MOFs as adsorbents to their utilization as fillers to enhance the performance of CO2-capturing membranes. The industrial perspective of the use of MOF technologies is also discussed for the process design of separation systems (pre-combustion and post-combustion along with others), and the recent developments of converting atmospheric CO2 to useful chemicals.
