Abstract

The Potential in Water Supply and Sanitation Services of the On Site Production of Sodium Hypochlorite (OSEC) Driven by PV Solar Source

Highlights

  • In developing countries, the construction and management of water treatment plants is one of the most diffused problems

  • Sodium Hypochlorite (NaOCl) is a powerful germicide able to remove 99.9% of bacteria, viruses, protozoa and fungal agents: it is used for disinfection, water purification, and food cleaning such as fruits and vegetables

  • The goal of the analysis is to evaluate the environmental impacts of two processes for the production of Sodium Hypochlorite: the benefits of local production can be evaluated through the following simplified LCA process

Summary

Introduction

The construction and management of water treatment plants is one of the most diffused problems. There are several technological solutions for water treatment but the appropriate choice can be taken only after an accurate analysis of all involved aspects, such as social, economic and technical. These are the reasons why technologies used have to be simple, affordable and sustainable. Sodium Hypochlorite (NaOCl) is a powerful germicide able to remove 99.9% of bacteria, viruses, protozoa and fungal agents: it is used for disinfection (wounds, surfaces, clothing, bed sheets, towels, dishes...), water purification, and food cleaning such as fruits and vegetables. Provided that the physical and chemical quality of the water is acceptable, disinfection by Sodium Hypochlorite provides the most effective mean for reducing the numbers of microorganisms in drinking water. At present chlorination is the most and widely applied in treating community water supplies [1, 2]
