This study reports for the first time application of electrocoagulation (EC) from laboratory to pilot scales treatment printing wastewater, a hazardous waste whose and disposal are strictly regulated. The wastewater was taken three real companies with strongly varying characteristics. process performed in operational optimization then applied scale. weight loss electrode generation sludge at bo...

A new arsenic removal process was designed combining: 1) iron nanoparticle addition, b) electrocoagulation, and c) electromagnetic separation. Results showed that arsenic could be removed with more than 99 % efficiency from liquid waste samples. Parameters that were found to have importance on the process were: a) nanoparticle dosage, b) electric voltage drop during electrocoagulation, b) pH of...

Thermophilic aeration and electrochemical reactions are well-established methods for wastewater treatment to reduce metallic content, organic inorganic matter, turbidity, coloration, nutrient levels. In this study, thermophilic aerobic oxidation (TAO) electrocoagulation (EC) were implemented together improve the quality of liquid fertilizer by reducing load toxicity swine manure. The influent i...

The main objective of this study is to optimize a two-step treatment for mature landfill leachate consisting electrocoagulation (EC) followed by Fenton or UVA-LED photo-Fenton processes aiming provide more efficient and feasible alternative strategy that also increases biodegradability decreases conductivity. Although 5 mA cm−2 EC cheaper than 10 per kg removed COD (0.63 vs. 0.89 € kgCOD−1), it...

BACKGROUND, AIM AND SCOPE Electrocoagulation (EC) may be a potential answer to environmental problems dealing with water reuse and rational waste management. The aim of this research was to assess the feasibility of EC-process for industrial contaminated effluents from copper production, taking into consideration technical and economical factors. EC-technology claims to offer efficient removal ...

We demonstrate that electrocoagulation (EC) using iron electrodes can reduce arsenic below 10 μg/L in synthetic Bangladesh groundwater and in real groundwater from Bangladesh and Cambodia, while investigating the effect of operating parameters that are often overlooked, such as charge dosage rate. We measure arsenic removal performance over a larger range of current density than in any other si...

We measure arsenic removal performance 15 over a larger range of current density tha...

The electrocoagulation (EC) process is an efficient and low-cost system for the purification of wastewater. aim this work was to investigate efficiency two types aluminum (Al) electrodes (Al alloy pure Al electrodes) treatment synthetic semi-skimmed milk Turbidity, chemical oxygen demand (COD), concentration species were monitored during experiments. effect various parameters, such as current d...

background; conventional chemical coagulation is considered as the old method to color and cod removal in textile effluent. electrocoagulation (ec) process is a robust method to achieve maximum removal. methods; this work was designed to compare the result of operational parameters including optimum ph and coagulant concentration for chemical coagulation with ferric chloride and alum. also, the...

BACKGROUND Animal wastes are of particular environmental concern due to greenhouse gases emissions, odor problem, and potential water contamination. Anaerobic digestion (AD) is an effective and widely used technology to treat them for bioenergy production. However, the sustainability of AD is compromised by two by-products of the nutrient-rich liquid digestate and the fiber-rich solid digestate...
