How effective aerated continuous electrocoagulation can be for tetracycline removal from river water using aluminium electrodes?

Enhanced electrocoagulation process for natural organic matter removal from surface drinking water sources: coagulant dose control & organic matter characteristics

“…The CV data for treated Murray River water [A254, EC: 7.8%, CC: 0.9%; colour, EC: 17%, CC: Several factors have been linked to the EC efficiency in removing pollutants including the electrode material, EC process time, EC cell voltage, EC cell electric current, electrolyte concentration and type, pH, temperature, distances between electrodes, electrode shape, EC cell structure and configuration of electrode electrical connections. 21,26,[56][57][58][59][60][61][62][63][64] In this study, the performance of the EC process for DOM removal (using an aluminium electrode, at the optimum pH and ambient temperature) was found to be related to the generated coagulant dose. This was also found to be similar to the comparative chemical coagulant dosing (CC) process.…”

Emerging investigator series: impacts of aeration flow rates and bubble sizes on PFOA/PFOS removal in electrocoagulation

“…This result indicates that higher airflow rate increased the turbulence and subsequently increased interaction between pollutants and metal hydroxide flocs. [44][45][46] Increasing airflow rates can increase turbulence, one previous study reported that the increased Reynolds number from 360 to 803 as the gas flow rate increased from 0.25 to 1.20 L min −1 . 29 The turbulence caused by aeration usually helps solutes penetrate the liquid film surrounding adsorbent particles, allowing solutes to more easily reach the adsorbent surface.…”

Highly Efficient Ultrasound-Driven Ti3+-Doped TiO2 with Oxygen Vacancies: A Promising Visible-Light Catalyst for Complete Sonophotocatalytic Degradation of Tetracycline

“…Studies indicate that approximately 90% of TC is excreted in feces and reaches the surface water, leading to its accumulation and subsequent pollution of soil and water. , The persistent occurrence of such antibiotics in the environment can disrupt the native microbial community and interfere with material circulation and energy flow in soil and water ecosystems, posing significant ecological and environmental risks. To address these concerns and safeguard the environment and all living beings, researchers have proposed various strategies to eliminate or degrade TC using physical and chemical techniques such as adsorption, ion exchange, electrocoagulation, ozonation, and biological processes . Although these techniques have effectively removed antibiotics, they also have drawbacks such as antibacterial resistance, large energy consumption, incomplete degradation due to the transfer of liquid to solid state, etc .…”
