Bio-regeneration of activated carbon: A comprehensive review
( Elsevier B.V. , 2018 , Article Review)The use of microorganisms to regenerate activated carbon (AC), bio-generation, can avert costly and logistically challenging ex-situ steam regeneration of carbon normally required to recover its adsorptive capacity. ... -
Carbon mineralization by reaction with steel-making waste: A review
( MDPI AG , 2019 , Article Review)Carbon capture and sequestration (CCS) is taking the lead as a means for mitigating climate change. It is considered a crucial bridging technology, enabling carbon dioxide (CO 2 ) emissions from fossil fuels to be reduced ... -
CFD and statistical approach to optimize the average air velocity and air volume fraction in an inert-particles spouted-bed reactor (IPSBR) system
( Elsevier Ltd , 2021 , Article)Inert-particles spouted bed reactor (IPSBR) is characterized by intense mixing generated by the circular motion of the inert particles. The operating parameters play an important role in the performance of the IPSBR system, ... -
CO2 Absorption Capacity and its Enthalpy of Absorption in Aqueous Blend of MDEA/Piperazine/Arginine
( Institute of Physics Publishing , 2020 , Conference Paper)In this work, the solubility data of CO2 in aqueous blends of N-Methyldiethanolamine, Piperazine and Arginine (MDEA/PZ/ARG) of a total concentration of two moles is presented. CO2partial pressure was varied from 9 to 99 ... -
CO2 Capture Using Hollow Fiber Membranes: A Review of Membrane Wetting
( American Chemical Society , 2018 , Article Review)Hollow fiber membrane contactors have several advantages that make them a good alternative to conventional absorption processes in the gas industry, and they have attracted the interest of many researchers. However, critical ... -
Competitive interference during the biodegradation of cresols
( Center for Environmental and Energy Research and Studies , 2018 , Article)Phenol and its methylated derivatives, cresol isomers, are hazardous pollutants that are commonly present in various industrial effluents and known to have detrimental effect on aquatic life as well as human health, due ... -
Effects of potassium hydroxide and aluminum oxide on the performance of a modified solvay process for CO2 capture: A comparative study
( John Wiley and Sons Ltd , 2021 , Article)In a previous work, the overall performance of modified Solvay process was investigated in the absence of ammonia, where carbon dioxide and brine treatments were accomplished in a single reaction and in the presence of ... -
Electrocoagulation treatment of reject brine effluent from Solvay process
( Desalination Publications , 2019 , Article)Solvay process is an efficient treatment technique for reject brine from desalination, where salinity is reduced by removing Na+ by adding NH3 . However, in this process large amounts of NH3 are consumed and Cl– ... -
Enhanced CO2 capture through reaction with steel-making dust in high salinity water
( Elsevier Ltd , 2019 , Article)Mineral carbonation (MC) is evolving as a possible technology for sequestering CO2 from medium-sized emission point sources. Industrial wastes have been recently used as an effective source for MC that have higher reactivity ... -
Enhancement of flocculation and shear resistivity of bentonite suspension using a hybrid system of organic coagulants and anionic polyelectrolytes
( Elsevier B.V. , 2020 , Article)In this study, the influence of the hybrid coagulation-flocculation system on the flocculation and shear resistivity of bentonite suspension has been investigated. Two short-chained coagulants, polyamine and polyDADMAC, ... -
Immobilization of microbial cells for the biotreatment of wastewater: A review
( Springer Verlag , 2019 , Article Review)Industrial wastewater often contains different complex impurities that are hazardous to the environment and human health, making wastewater treatment a necessity prior to its disposal. This review focuses on cell immobilization ... -
Influence of polyelectrolyte structure and type on the degree of flocculation and rheological behavior of industrial MBR sludge
( Elsevier B.V. , 2020 , Article)The influence of polyelectrolyte's type and structure on the rheological characteristics of industrial highly stable membrane bioreactor (MBR) sludge have been investigated and were related to its degree of flocculation ... -
Metal-oxide nanotubes functional material tailored for membrane water/wastewater treatment
