Potential improvement to a citric wastewater treatment plant using bio-hydrogen and a hybrid energy system

Preparation and characterization of raw and carbon from banana peel by microwave activation: Application in citric acid adsorption

“…Removal of CA is accomplished using different methods such as membrane filtration [8], anaerobic treatment [9], electrochemical oxidation [10], biohydrogen production [11], microbial treatment [12], catalytic wet peroxidation [13], and anaerobic and multilevel aerobic digestion [14][15][16]. However, these processes are associated with very high operational costs [7].…”

Commercialization model of hydrogen production technology in Taiwan: Dark fermentation technology applications

“…The exploitation of wastewater as substrate for hydrogen production with concurrent wastewater treatment is an attractive and effective way of tapping clean energy from renewable resources [13]. A technical-economic model, based on hydrogen utilization, is presented and analyzed by Zhi et al [14] to estimate the potential improvement in a citric wastewater plant. The model assesses the size, capital cost, annual cost, system efficiency, and electricity cost under different configurations.…”

Feasibility study and process optimization of citric acid wastewater treatment and biomass production by photosynthetic bacteria

“…(2015) [1][2][3][4][5][6][7] www.deswater.com doi: 10.1080/19443994.2015.1005687 production is a direction in citric acid wastewater treatment. The method using photosynthetic bacteria (PSB) in wastewater treatment is qualified with this feature, and has attracted increasing attentions.…”

“…Therefore, large amounts of citric acid wastewater need to be properly treated before discharged. Commonly, citric acid wastewater was treated by up-flow anaerobic sludge bed, sequencing batch reactor, high-temperature anaerobic digester, Fenton oxidation, and so on [2][3][4][5]. Although these methods are effective in reducing organic pollutions, their treatment process are often long and complicated, and they could generate large quantities of excess sludge and lack of renewable resource cycle.…”
