Solar Water Disinfection Market Demand, Scope, Global Opportunities, Challenges and Key Players by 2030

Global Solar Water Disinfection Market: Overview

Solar water disinfection has become one of the most practical methods and least expensive techniques used by more than 6 million people worldwide to disinfect non-drinking water. The zero intervention measure has gained popularity among rural people and low-income areas, especially in developing countries, to purify drinking water. These areas are characterized by poor access to water sources and the absence of adequate sanitation. Contaminated water has been proven to be the cause of various gastrointestinal illnesses, especially diarrhea, infecting at least 6 billion people worldwide. The bactericidal action of solar irradiation in water has been established in numerous scientific publications. Communities in low-income areas are infected with a variety of pathogenic microorganisms such as faecal coliforms, protozoa and various viruses.

The process involves exposing the contaminated water volume of approximately two liters of transparent polyethylene terephthalate (PET) bottles to direct sunlight for at least six hours. The mechanism of action is not very clear. However, the synergistic impact of UV photons present in solar energy and the slight thermal heating produced during exposure to the sun are essential to the disinfection process. Sunlight absorbed in water catalyzes the generation of reactive oxygen species (ROS) at the intracellular level of pathogenic microorganisms, triggering disinfection. The effect of this mechanism has been adequately validated in E. coli. The technique forms one of the key elements of the solar water purification system, the other being the solar distillation process. Compared to conventional water purification techniques such as chlorination and artificial UV radiation, solar water disinfection is preferred in low-income communities because the technique does not require expensive and sophisticated equipment that stimulates the solar water disinfection market.

Global Solar Water Disinfection Market: Overview

Growing environmental concerns and the depletion of conventional resources have led to a move towards the use of renewable sources for energy production. Currently, solar energy is used for a number of applications ranging from power generation to water purification.

Solar water disinfection involves the use of solar energy for water purification. The technique helps get rid of bacteria, viruses, protozoa and worms that can be harmful to humans.

The report is a very important tool to understand the solar water disinfection market drivers, challenges and trends that will impact the global solar water disinfection market growth till the end of the forecast period in 2025.

Global Solar Water Disinfection Market: Drivers and Restraints

The low cost of solar water disinfection equipment, solar energy initiatives, government support, increasing water pollution and growing awareness of the importance of safe drinking water are the Key factors driving the global solar water disinfection market.

However, factors such as lack of awareness in rural areas where the incidence of waterborne diseases is high and reliance on sunlight for the operation of sewage treatment plants are restraining the growth of this market. Nevertheless, developing countries in Asia-Pacific and Africa combined with the advancement in filtration technologies of bacteria and other toxic agents will provide growth opportunities for the global water disinfection market.

Global Solar Water Disinfection Market: Market Segmentation

The global solar water disinfection market is segmented on the basis of methodology, application, and geography. Based on contaminated water treatment methodology, the market can be segmented into effects of electricity, ultraviolet radiation, and heat. Electric powered solar disinfection uses electricity generated using photovoltaic cells to purify water. The thermal water disinfection method uses solar energy to heat the water. Heat from infrared radiation can be stored using solar collectors. The ultraviolet radiation method involves the use of sunlight and polyethylene terephthalate (PET) bottles to purify water.

Solar water disinfection equipment provides economical and environmentally friendly techniques for water purification. These equipments are suitable for use in refugee camps and disaster relief situations to provide drinking water to the affected population. However, solar water disinfection equipment is not effective against non-biological agents such as chemicals and toxic metals.

Global Solar Water Disinfection Market: Regional Outlook

The global solar water disinfection market is analyzed based on the areas where solar water disinfection equipment can be used. Regions with high concentration of polluted water are the potential growth areas of the solar water disinfection market. Major regions include Honduras and El Salvador in North America; Bhutan, India, Pakistan, Indonesia and Nepal in Asia-Pacific; Burkina Faso, Ethiopia, DR Congo and Kenya in the Rest of the World region.
