Global Water Disinfection Market Size, Share, Opportunities, And Trends By Method (Ultraviolet Light, Chlorination, Ozonation, Distillation, Others), By End-User (Municipal, Industrial), And By Geography - Forecasts From 2025 To 2030

Water Disinfection Market Size:

The global water disinfection market is expected to grow from US$29.342 billion in 2025 to US$34.952 billion in 2030, at a CAGR of 3.56%. 

The removal, deactivation, or extermination of harmful microorganisms in water is referred to as water disinfection. Disinfection can be accomplished using either physical or chemical disinfectants. Organic pollutants in water that act as nutrition or habitat for microbes are also removed by the agents. Disinfectants do more than just destroy germs. Disinfectants can also have a residual impact, meaning they stay active in the water after disinfection. After disinfection, a disinfectant prevents harmful bacteria from proliferating in the plumbing and recontaminating the water.

Concerns regarding disinfection byproducts (DBPs), many of which are recognized or suspected carcinogens. Continuous outbreaks of waterborne disease due to chlorine-resistant organisms such as Cryptosporidium and Giardia lamblia, including in developed countries.  Furthermore, the expanding global population, combined with rising urbanization, are some of the primary drivers of the water disinfection equipment market. Scarce freshwater resources, combined with a growing population, are driving governments all over the globe to develop new water treatment facilities and update old ones in order to supply safe drinking water to everybody. Strict laws and industry requirements for wastewater treatment across various sectors are another driving reason for the growth of the water disinfection equipment market.

Water Disinfection Market Growth Factors:

• Increase in applications of UV disinfection equipment.

UV disinfection equipment can eliminate any live microbe in the air, water, or on surfaces, therefore preventing disease transmission. When bacteria, viruses, and protozoa are exposed to germicidal UV light wavelengths, they lose their ability to reproduce and infect. UVC is a kind of radiation that has been shown to deactivate or eliminate a variety of infections, including the virus that causes COVID-19. A 254 nm mercury UV lamp, according to the International Ultraviolet Association (IUVA), killed 99% of SARS-CoV-2, also known as the coronavirus. When chlorine-based disinfectants take nearly 20 minutes to adequately treat the water tank, UV disinfection equipment uses UVC lamps to perform the same work in less than 10 seconds.

The UV disinfection equipment market is expected to be driven by high R&D investments by manufacturers to improve the performance of UV disinfection equipment for large volume applications such as municipal drinking water and industrial process water treatment. Supporting government programs for water and wastewater treatment has boosted technological development in growing nations such as India and China. The adoption of UV disinfection equipment is projected to benefit from increased demand for clean and safe drinking water as a result of the rising population and scarcity of freshwater resources.

Water Disinfection Market Restraints:

• Higher investment costs

Although a majority of ozone systems do not need substantial maintenance. Some systems employ an air-drying substance that must be changed regularly. It is also important to clean the water storage tank regularly and to inspect pumps, fans, and valves for damage and wear. If UV radiation produces ozone, the lamp must be changed periodically. Any pre-treatment or post-treatment equipment might necessitate further upkeep. Ozone treatment can potentially result in the formation of toxic byproducts in drinking water. For example, if bromide is present in the raw water, ozone interacts with it to create bromate, which has been proven to cause cancer in rats.

North America has a substantial market share owing to the high awareness regarding water quality among the masses and the resulting enormous need for improved water treatment technologies. During the forecast period, the Asia-Pacific region is anticipated to be the fastest-growing regional market for water disinfection equipment. This expansion can be attributed to an increase in the number of industrial facilities in sectors such as energy and power, food and beverages, chemicals, and pharmaceuticals. Strict legislation and rules governing drinking water quality, as well as increased government efforts and policies, would drive demand for water disinfection equipment in the area, favorably affecting the APAC water equipment market growth during the projected period.
