Abstract
In this contribution a possibility of electrochemical production of chlorine for water disinfection, by using photovoltaic panels from solar energy, is described. A simple way of chloride production by means of a photovoltaic panel, comparable with classical electrical power source was performed on an experimental device. By using photovoltaic panel with nominal output 50 W and solar irrigation 380 – 550 W/m2 chlorine production was 0.3 mg/min, which represents amount of chlorine sufficient for disinfections of approximately 4000 l water per day.
Highlights
Water disinfection is important to provide for a hygienic quality of water
In the first series of experiments a hermetic electrolytic cell was connected to a regulated laboratory electric power source and an electro-chemical production of chlorine was tested
It was found that maximal concentration of chlorine in water was 4.2 mg/dm3 and this was achieved after 25 minutes of electrochemical chlorine production
Summary
Water disinfection is important to provide for a hygienic quality of water It is a concern of drinking, service, heating and cooling waters in industry and waters for public and private pools. A frequent way of chlorine production is electrolysis of sodium/potassium chloride solutions. During this process sodium/potassium hydroxide are produced. The main technologies are mercury, diaphragmatic and membrane electrolysis In these procedures the base material is mainly sodium chloride or less frequently potassium chloride. In this work we describe an application of PV panels for electrochemical production of chlorine which is subsequently used for disinfection, preferably service water
