“…Energy usage is reduced when electrolyte concentration rises. In the AO and AO-H 2 O 2 processes, organic compound elimination and mineralization occur more quickly in the presence of NaCl or CaCl 2 [ 20 ]. The voltage between electrodes would be substantially increased by this insulating layer, and it results in a considerable reduction in current efficiency.…”

The elimination of organic compounds in coffee processing effluent utilizing electrochemical oxidation (ECO) as well as a combination of electrochemical oxidation (ECO) and ultraviolet and hydrogen peroxide (UV/H2O2) was explored. Then, the percentage reduction of chemical oxygen demand (COD) was investigated. The effect of different experimental factors such as solution pH, sodium chloride (NaCl) concentration, calcium chloride (CaCl2) concentration, electric current, electrolysis duration, and hydrogen peroxide dosage on the percent removal efficiency of the hybrid electrochemical oxidation (ECO) with the ultraviolet and hydrogen peroxide (UV/H2O2) process has been investigated. The response surface methodology (RSM) based on central composite design (CCD) was used to organize the trial runs and optimize the results. The hybrid electrochemical oxidation (ECO) with the ultraviolet and hydrogen peroxide (UV/H2O2) process removed 99.61% of the chemical oxygen demand (COD) with a low power usage of 1.12 kWh/m3 compared to the other procedures, according to the experimental data analysis. These findings were obtained with a pH of 7, a current of 0.40 A, 1.5 g of CaCl2, and a total electrolysis period of 40 minutes. When it came to eliminating organic compounds from coffee manufacturing effluent, CaCl2 outperformed NaCl. Analysis of variance (ANOVA) with 95% confidence limits was used to examine the significance of independent variables and their interactions.

“…The EO process as a simple, economical, safe, and eco-friendly technology is capable of degrading compounds that are resistant to biodegradation by anodic direct and indirect oxidation [16,17]. Indirect oxidation in the EO process is due to the oxidizing compounds produced by the EO process, and these compounds can non-selectively oxidize organic compounds [18,19]. H 2 O 2 is used as an oxidant in oxidation processes and as a propellant for hydroxyl radical production in Fenton processes [20].…”

“…Chemical fumigation has been approved by the industry to control microbial safety of tree nuts (Almond Board of California, 2005). The disinfectants include phenol derivatives, alcohols, aldehydes, halogens, and gas sterilizers (Fallahzadeh et al., 2019; Ghaneian et al., 2016). Among which, sulfuryl fluoride, aluminum phosphide, and magnesium phosphide are the most commonly used pesticides for tree nuts, and they are approved by the Environmental Protection Agency (EPA) (Isikber et al., 2006; Jimenez et al., 2015; Mitcham et al., 2004; Pello & Kimmel, 2007; Rosskopf et al., 2005; U.S. EPA, 2007).…”

Tree nuts are important economic crops and are consumed as healthy snacks worldwide. In recent years, the increasing needs for more efficient and effective postharvest processing technologies have been driven by the growing production, higher quality standards, stricter food safety requirements, development of new harvesting methods, and demand to achieve energy saving and carbon neutralization. Among all, the technologies related to drying, disinfection, and disinfestation and downstream processes, such as blanching, kernel peeling, and roasting, are the most important processes influencing the quality and safety of the products. These processes make up the largest contribution to the energy consumptions and environmental impacts stemming from tree nut production. Although many studies have been conducted to improve the processing efficiency and sustainability, and preserve the product quality and safety, information from these studies is fragmented and a centralized review highlighting the important technology advancements of postharvest processing of tree nuts would benefit the industry. In this comprehensive review, almonds, walnuts, and pistachios are selected as the representative crops of tree nuts. Current statuses, recent advances, and ongoing challenges in the scientific research as well as in the industrial processing practices of these tree nuts are summarized. Some new perspectives and applications of tree nut processing waste and by‐products (such as the hulls and shells) are also discussed. In addition, future trends and research needs are highlighted. The material presented here will help both stakeholders and scientists to better understand postharvest tree nut processing and provide technological recommendations to improve the efficiency and sustainability, product quality and safety, and competitiveness of the industry.
