Solar water disinfection, in short SODIS, is a type of portable water purification that uses solar energy to make biologically-contaminated (e.g. bacteria, viruses, protozoa and worms) water safe to drink. Water contaminated with non-biological agents such as toxic chemicals or heavy metals require additional steps to make the water safe to drink.

Solar Panel Battery Storage: Can You Save Money Storing

Without solar panels, you could use a battery to make the most of a time-of-use tariff by storing up electricity while it''s cheap (overnight, for example) to use during peak times. But if you''re at

Solar Water Purification: A Starting Guide

Solar water disinfection is a sort of portable water purification that cleans water through solar energy in order to remove contaminants such as bacteria, viruses, and protozoa. It does so through a mixture of electricity

Solar water disinfection | Climate Technology Centre & Network

Solar water disinfection (SODIS) uses two components of the sunlight for the water disinfection. The first, UV-A radiation has a germicidal effect. The second component, infrared radiation,

What to use for disinfection of solar photovoltaic panels

6 FAQs about [What to use for disinfection of solar photovoltaic panels]

What is solar water disinfection?

Solar water disinfection, in short SODIS, is a type of portable water purification that uses solar energy to make biologically-contaminated (e.g. bacteria, viruses, protozoa and worms) water safe to drink.

Can photovoltaic panels be used in solar drinking water disinfection?

The integration of disinfection technologies based on artificial UV radiation, powered by photovoltaic panels in solar drinking water disinfection systems is a promising path to be explored , , as it can balance the fluctuation in the availability of desired doses of UV radiation, resulting from the momentary shading of the sun.

Can solar water disinfection be used for microbiologically contaminated water?

Microbiologically contaminated water is filled into transparent containers and exposed to full sunlight during 6 hours. Very turbid water with a turbidity of more than 30 NTU cannot be used for SODIS. Solar water disinfection (SODIS) is a water treatment method that:

What materials can be used for mixed solar water disinfection?

In addition, the transparent parts of the panel, including the microlenses, can be made of material with high UV transmittance (e.g., borosilicate, quartz, pyrex), and thus a high-efficiency reactor for mixed solar water disinfection systems based on synergy of heat and UV will be obtained.

What is the basic technique of solar disinfection?

The basic technique of SODIS is demonstrated in Fig. 1. Transparent containers are filled with whatever water that has been collected locally, and these are placed in direct sunlight for at least 6–8 h, after which time the exposed water should be biologically safe to drink. Infographic demonstrating the basic technique of solar disinfection.

Can solar water disinfection systems be used in large-scale public drinking water supplies?

For this, it is necessary to develop high-performance solar water disinfection systems, which can be applied in large-scale public drinking water supplies at low cost. These desired advances need to become targets of future research, and the following aspects should be considered:
