In this study electrocoagulation (EC) process with sacrificial aluminum anode was used to separate crude oil from synthetic oily wastewater emulsion. A preliminary experimental study was performed to evaluate the most accurate operating parameters, which are then used for the determination of crude oil removal efficiency. The experimental results indicated that electrocoagulation was very e...

Vasectomy or male sterilisation is the severing or electrocoagulation of the vas deferens connecting the testes to the seminal vesicles and urethra. It is a safe and a highly effective operation that offers a permanent method of contraception. Reversal of a vasectomy is possible but can be difficult and is not always successful. The permanency of the procedure means that careful counselling is ...

While generally safe, the most feared complication of colonoscopy is perforation of the colon, occurring in nearly 1 in 1,000 procedures, and is more common when polypectomy is performed and electrocautery is used. Less commonly known is the post-polypectomy electrocoagulation syndrome, a transmural burn of the colon which mimics the signs and symptoms of perforation as well as the time course,...

Warts are benign proliferations of the skin and mucosa caused by infection with human papillomavirus. They are commonly treated with destructive modalities such as cryotherapy with liquid nitrogen, local injection of bleomycin, electrocoagulation, topical application of glutaraldehyde, and local and systemic interferon-β therapy. These treatment modalities often cause pain and sometimes scarrin...

The removal of indium ions from aqueous solution was carried out by electrocoagulation in batch mode using an iron electrode. Various operating parameters that could potentially affect the removal efficiency were investigated, including the current density, pH variation, supporting electrolyte, initial concentration, and temperature. The optimum current density, supporting electrolyte concentra...
