Electrocoagulation for Water Treatment: the Removal of Pollutants using Aluminium Alloys, Stainless Steels and Iron Anodes
… treatments is becoming increasingly important. Electrocoagulation is one of the more promising approaches as it is simple and efficient and, compared with traditional processes, has the advantages of short treatment times and low sludge production. The objective of this research was to determine …

Electrocatalytic treatment of wastewaters
The electrocoagulation tests were carried out considering both relatively high metal contents (in the range of ppm) and very low metal concentrations (in the range of ppb). The experiments with very low metal concentrations were carried out in the framework of a collaboration project with the …

The Pharmacokinetics of Oxytetracycline in Dogs With Normal and Impaired Renal Function
A renal failure model was developed in 29 dogs by electrocoagulation of one renal cortex and contralateral nephrectomy to enable the adjustment of therapeutic drug doses in relation to renal function. The magnitude of renal dysfunction, defined by the percentage of normal glomerular filtration rate …
