Treatment of hospital wastewater by oxidation using potassium ferrate: Systematic review

As a mix of oxidant and flocculent, potassium ferrate can possibly be a very efficient chemical with sewage processing. In their sewage, hospital discharge significant amounts of chemicals and microbiological organisms. Antibiotics, X-ray contrast agents, disinfectants, and medicines are among the problem compounds found in hospital sewage. Many of these chemicals are resistant to standard sewage processing. They wind up in surface waters, where they have the potential to disrupt the aquatic ecology and the food chain. Drinking water derived from surface water is extremely hazardous to human. In this paper, different approaches to hospital sewage processings have been reviewed. The principles of hospital sewage processing by corrosion using potassium ferrate were outlined in details for focusing on the reviewing the applications of this method in treating different sources of hospital sewage.
