Abstract In this study, a high-gravity (HiGee) process incorporating CO2 and NOx reduction from flue gas in a petrochemical plant coupled with petroleum coke fly ash (PCFA) treatment was established. The performance of HiGee was systematically evaluated from the engineering, environmental, economic, and energy aspects (a total of 15 key performance indicators) to establish the air pollution, energy efficiency, waste utilization nexus. The engineering performance was evaluated that lower energy c...

Abstract A high-gravity rotating packed bed (HiGee RPB) is very efficient at removing pollution because it exerts a strong high centrifugal and allows tiny droplets to form, which allows the control of gaseous and particulate air pollution. In this study, fine particles that are removed from integrated circuit (IC) chip carbonization process using a RPB are evaluated under different high gravity factors and liquid-to-gas ratios. The greatest number of particles captured per energy consumption is...

Abstract In Taiwan, a significant amount of greenhouse gas emissions occur as a result of anthropogenic activities and rapid urbanization. In order to comply with the ‘Greenhouse Gas Reduction and Management Act’ and the “Nationally Determined Contribution” to abide by Paris Agreement, the Taiwanese Environmental Protection Administration has devised a framework for a carbon offset mechanism before a cap and trade scheme is introduced. This paper gives a snapshot of the Taiwanese context in impl...

The bauxite-derived adsorbent, activated alumina (AA), has a current annual global market of over 600 million USD, and of this more than one-third of AA is used for defluoridation of fluoride-bearing water. The commonly used Bayer process for production of AA suffers from thermodynamic inefficiency thereby raising costs, and also causes significant environmental damage. Here, we evaluate three other bauxite-derived adsorbents as alternatives to AA for water defluoridation: mildly processed bauxi...

Abstract Corn stover provides a great potential of bioenergy and biomaterial production through biorefinery, rather than being discarded as solid wastes. Appropriate pretreatments can enhance the biodegradability and digestion efficiency of lignocellulosics, and NaOH pretreatment is considered as an effective method. However, most NaOH pretreatments are usually performed at high temperatures (>100 °C) and over a long reaction time (∼days). In this study, we utilize both CaO-additive and ultrasou...

Abstract Carboxylated chitosan (CPCTS) is used as substrates in the design and synthesis of CPCTS-based flocculants through UV-initiated polymerization techniques. The synthesized flocculants are applied to remove Cr and Ni ions from chromic acid lotion and electroplating wastewater through two-stage flocculation. This study investigates the effect of flocculant dosage, pH, reaction time, and stirring speed on the removal efficiency of Cr and Ni ions. Results indicated that the total Cr removal ...

Abstract In this study, a proposed integrated high-gravity technology for air pollution control, CO 2 capture, and alkaline waste utilization was comprehensively evaluated from engineering, environmental, and economic perspectives. After high-gravity technology and coal fly ash (CFA) leaching processes were integrated, flue gas air emissions removal (e.g., sulfate dioxide (SO 2 ), nitrogen oxides (NO x ), total suspended particulates (TSP)) and CO 2 capture were studied. The CFA, which contains ...

Abstract Bioretention systems have been found to be potential candidates for the removal of various pollutants/nutrients from rainfall or stormwater runoff. Despite bioretention has been widely developed for the removal of nutrients from stormwater, effective removal of both phosphorus and nitrogen is still a challenge. Hence, in this study, bioretention systems modified by alkaline solid waste media have been reported for the effective removal of nutrients. Six different types of solid wastes w...

Wastewater treatment can consume a large amount of energy to meet discharge standards. However, wastewater also contains resources which could be recovered for secondary uses under proper treatment. Hence, the goal of this paper is to review the available green energy and biomass energy that can be utilized in wastewater treatment plants. Comprehensive elucidation of energy-efficient technologies for wastewater treatment plants are revealed. For these energy-efficient technologies, this review p...

Abstract Evaluating the performance of wastewater treatment represents a challenging and complex task as it usually involves engineering, environmental and economic (3E) factors. In this study, we developed an 3E triangle model to evaluate the performance of environmental technologies (i.e., anaerobic-anoxic-oxic reactors, oxidation ditches, and membrane bioreactors) and ecological technologies (i.e., stabilization ponds, constructed wetlands, and slow-rate systems) for wastewater treatment. A t...
