Bioenergy production from sediment microbial fuel cells has gained special attention for its application as a power source for environmental sensors. A sediment microbial fuel cell is a device capable of generating energy from sediments and electrolytes present in water bodies. Numerous factors must be considered to improve cell efficiency. However...

This chapter focused on the use of constructed wetlands (CWETs) for the removal of organic matter and phosphorus contained in cropland wastewater (CropWW). CropWW was obtained from an agricultural drain located in the most representative irrigation module of an agricultural hydrological basin. The treatment system consisted of a pretreatment for ph...

The anodic Fenton degradation of Basic Blue 9 (BB9) dye was evaluated using a divided parallel plate reactor with a cationic membrane (Nafion® 117 or reverse osmosis). Hydroxyl radicals were produced by the catalytic decomposition of H2O2 by the ferrous and ferric ions generated in the anolyte (0.05 M Na2SO4, pH ~ 2) from the oxidation of a galvani...

In this research, nutrient recovery and organic matter removal from agricultural wastewater (AWW) were simultaneously evaluated through an advanced oxidation process (AOP). For this purpose, a 30 W/m2 UV/H2O2 system optimized regarding oxidant reagent dose and UV irradiation time was configured. The evaluated levels were 48.9, 65.3, and 84.6 Mm of...

The objective of this study was to identify water pollution problems and obtain useful information for the sustainable extraction of water from the Culiacan River aquifer. Data from 6 sampling sites were used in the period from 2012 to 2019. A spatial geostatistical analysis was carried out to describe the water quality of the aquifer by using isoc...

This study provides an integrated assessment of hydrogen peroxide (H2O2), potas- sium peroxymonosulfate (PMS), and sodium percarbonate (PCA) performance in Albendazole (ABZ) degradation during advanced oxidation processes. The experi- ments were conducted in a UV photoreactor (16 mW m−2). Initially, H2O2 was tested as a model oxidant using ABZ/oxid...

Divided electrochemical reactors allow the design of strategies to take advantage of the two reactions of the redox pair involved for wastewater treatment. Nafion membranes are the most used separators in these cells. These membranes have demonstrated high efficiency, but their high costs make the process more expensive. The present work focuses on...

The presence of synthetic azo dyes in water can affect human health and the environment. Conventional treatments are not suitable to remove these synthetic dyes, as most of them have complex structures. In this work, the removal of Basic Blue 9 (BB9) dye was evaluated by using four different wastewater treatments. Biological treatment consisted of...

Deep learning has made essential contributions to classification and detection tasks applied to precision agriculture; however, it is vitally important to move towards an adoption of these techniques and algorithms through low-cost and low-consumption devices for daily use in crop fields. In this paper, we present the training and evaluation of fou...

In this study, a real textile effluent (RTE) was treated by the electro-Fenton method in a parallel plate reactor. A carbon fiber cathode and a stainless-steel mesh anode were used as electrodes. The effluent was characterized, and dilute solutions were prepared with initial chemical oxygen demand (COD) concentrations of 50, 100, 200, 250, and 300...

The biodegradation of domestic wastewater contaminants has been carried out using microorganisms immobilized in sodium alginate gel (Alg‐Na). A fixed bed reactor with immobilized microorganisms was used for the treatment of domestic wastewater. A wastewater pretreatment was carried out to remove the larger particulate matter, which consisted of a r...

Anodic Fenton treatment (AFT) has been extensively applied for water remediation. In general, three different bench-scale divided (salt bridge or ion membrane) reactors have been focused to treat small volumes (90-350 mL) and low concentration (20-400 M) of organic pollutants in short treatment periods (2-40 min). The best experimental condition o...

In this work, an electrochemical reactor of parallel plates oxidized organic pollutants from the cathodic and anodic compartments. The Fenton reagent was produced in situ from the electrogenerated H2O2 in the cathode compartment to degrade 70 mg L⁻¹ of acid orange 7 (AO7). The initial concentration was eliminated at the end of the treatment, where...

In this study, a micro-scale parallel plate reactor was built to electrochemically generate hydrogen peroxide (H2O2) and to develop the Fenton reaction in situ, for the treatment of toxic organic pollutants. Two types of carbon materials were compared and used as cathodes: unidirectional carbon fiber (CF) and reticulated vitreous carbon (RVC). As a...
