Disinfection

• Experiments demonstrate the multifunctionality of shock electrodialysis. • Besides deionization and filtration, nanoparticles can be separated by charge. • Bacteria in the feedwater are either filtered or killed by large electric fields.

An automatic pH–ORP (oxidation–reduction potential) titration device was developed and applied to dynamically control the wastewater chlorination and dechlorination doses in this study. In the pH–ORP titration and back-titration process, the monitoring peaks and valleys on the pH and ORP profiles co

The availability of freshwater to meet different water needs has raised serious concerns in the last decades all around the world. Water scarcity, deterioration of quality and increasing demand have led to the development and use of alternative sources of water. Reclamation and recycling are now con

We investigate the potential for reactivation to restore infectivity to UV-damaged bacteriophage 2MPØ isolated from wastewater. The virus belongs to the Myoviridae family of the tailed phages. This Phage was chosen for detailed analysis, and was inspected by electron microscopy, host range determina

The use of potassium ferrate(VI) as an alternative water remediation chemical has been studied and is reported in this paper. The water remediation performance of potassium ferrate(VI) was evaluated in comparison with sodium hypochlorite, ferric sulphate (FS) and aluminium sulphate (AS). The effects

Following an increased interest in the last decade to employing peracetic acid (PAA) as an alternative disinfectant to chlorination, a study was started to investigate the technical, economic and chemical suitability of PAA for disinfecting municipal wastewater to be reused in agriculture. Laborator

One of the most critical problems in developing countries is the lack of drinking water. People in these regions are supplied with surface water, which contains a significant amount of microorganisms that can cause several diseases. In fact, one of the main causes of infantile mortality is the high

To produce healthy drinking water is the main problem almost all over the world. The aim of this study is to find an efficient method to remove humic substances (HS) from water, because HS cause some types of cancer when they react with chlorine or other disinfection materials composing disinfection

This paper reports the experimental results of a pilot-scale (100 m3/h) investigation, carried out at the West Bari (S. Italy) municipal wastewater treatment plant, focused on parasite removal and disinfection by-product (DBP) formation during the UV disinfection of clarified (CL) and clarified-filt
