Summary: This review examines the removal of fluoride from natural groundwater using electrocoagulation, with aluminum and aluminum alloys proving to be the most effective materials for fluoride removal. Iron, on the other hand, does not meet WHO guidelines for fluoride removal. The use of parallel plate continuous EC reactors allows for flow rate control and uniform electrode wear, with relatively low operating costs.

Summary: Treatment of wastewater containing organics and NH4+-N is a challenging task. A new composite anode (CA) was designed and used in the electrochemically assisted ozonation (EAO) process to improve the removal efficiency. The results showed that CA-EAO exhibited higher efficiency in organic and NH4+-N removal compared to traditional Fe-EAO and DSA-EAO.

Summary: Electrocoagulation is a cost-effective method for treating water and wastewater, but with some design limitations. This study developed a new EC unit design using drilled plates to mix the solution, reducing power consumption. Experimental results showed that 99.9% iron removal rate could be achieved by optimizing current density, pH, iron concentration, and treatment time.

Summary: This study investigated the removal of polyamide microplastics from wastewater using electrocoagulation. The combination of iron anode and aluminum cathode (Fe-Al) exhibited the highest removal efficiency. The removal efficiency of microplastics increased with higher applied voltage and electrolyte concentration. The optimized conditions for polyamide removal were using Fe-Al electrodes, with a plate spacing of 2.5 cm, an applied voltage of 10 V, an initial pH of 7, and an electrolyte concentration of 0.02 mol/L. This study highlights the potential of electrocoagulation for microplastics removal and provides insights for operational parameter optimization.

Summary: This paper investigates the simultaneous removal of arsenic, fluoride, and hydrated silica from natural well water using electrocoagulation. The best results were achieved at a current density of 5 mA cm-2 and a linear flow velocity of 1.2 cm s-1. This method effectively reduced the concentrations of arsenic and fluoride below the World Health Organization's guideline and maintained a hydrated silica concentration of 33 mg L-1.

Summary: The increased availability of toxic Al3+ is the main limitation for plant growth on acid soils. However, some plants adapted to acid soils can tolerate and accumulate high levels of Al in their aerial parts. Previous studies have focused mostly on acid soils in the northern and southern hemispheres, while acid soils outside of these regions have been neglected. This study investigated the acid soils of tea plantations in Northern Iran and found that several species can accumulate high amounts of Al and Fe, making them suitable for soil rehabilitation.

Summary: Conventional water treatment systems have been improved through ozonation or UV irradiation processes in recent years. The study analyzed the efficiency of four hybrid processes for removing inorganic and organic pollutants, where the coagulation process was found to be most efficient for metal ions removal. Ozonation before coagulation increased the removal of color and UV254 absorbance, while the addition of UV irradiation or adsorption had little impact on metal ions concentration in water.

Summary: The study investigated the use of an electrochemical oxidation-in-situ coagulation (ECO-IC) process for efficient treatment of mixed industrial wastewater contaminated with heavy metals and organic pollutants. The process successfully degraded organic contaminants and precipitated heavy metals in the solution. ECO-IC shows promise as an effective pre-treatment method for coagulating heavy metals in real industrial wastewaters.

Summary: The potential of detecting specific formation elements separated by small distances inside boreholes was investigated in this study. The neutron probe, utilizing the associated alpha particle method (AAP) as its operational principle, was used for the measurements. The results suggest that the neutron probe with AAP has the capability to distinguish between different parts of the formation separated by 10 cm.
