WATER TREATMENT BIOCIDES MARKET OVERVIEW

The global water treatment biocides market size was USD 4.33 billion in 2025 and is projected to touch USD 6.74 billion by 2034, exhibiting a CAGR of 5.0% during the forecast period.

The biocides market related to water treatment is very vital, as it helps to ensure the quality of water in industrial, municipal and commercial practices. Biocides refer to chemical compounds applied in the control of harmful microorganisms in water systems (ex: bacteria, algae and fungi). They are critical in such processes as cooling water treatment, production of oil and gas, and management of wastes to avert biofouling and corrosion. Emerging trends in urbanization, industrialization and increasing water reuse have necessitated the need to come up with viable biocidal treatment. Moreover, there is an imposition of strict environmental and health laws on the water quality, which have influenced the use of biocides in various industries. Oxidizing and non-oxidizing biocides are highly applied based on the end use of the biocide. As the issue of water scarcity and contamination continue to raise, plants are now seeking sustainable and low-toxicity and high-performance biocide, and this has sparked the development of eco-friendly formulations as well as advanced delivery systems in the global water treatment industry.

COVID-19 IMPACT

Water Treatment Biocides Industry Had a Negative Effect Due to Disrupting International Deliver Chains

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and returning to pre-pandemic levels.

The first impact on the global water treatment biocides market growth was caused by the COVID-19 pandemic lockdown, disruptions in the supply chain, and decreased industrial activities. The manufacturing plants in the oil and gas, power generation, and paper production industries were also shut down and hence a reduction in the need of biocidal water treatment chemicals was experienced. The problems of logistics and lack of labor also slowed down the process of procurement of raw materials and production. The city water treatment processes were limited in the budget and maintenance procedures were delayed. Even though the healthcare and pharmaceutical sectors needed clean water amid the pandemic, they would not be enough to counter the losses in other sectors. Nevertheless, after the pandemic, the recovery work slowly raised the market, with industries becoming operational again and governments focusing on hygiene, sanitation, and management of safe water. Another effect of the pandemic is the tendency of industries to use automation and remote monitoring as treatment methods of water in order to achieve better efficiency and reduction of risk in future operational plans.

LATEST TRENDS

Rising Adoption of Green and Sustainable Biocides Helps in Market Expansion

One of the key trends that determine the water treatment biocides market is the utilization of green and sustainable biocides. Environmental laws and growing concern regarding environmental safety are pushing industries towards biodegradable, low toxicity as well as non-halogenated formulations. Conventional biocides that are usually based on chlorine or bromine substances may produce detrimental by-products that contaminate water bodies and ecosystems. Consequently, studies have increased on how to come up with bio-based alternatives that are based on natural substances, including plant extracts and enzyme agents. The firms also invest in controlled-release and encapsulated biocides in which the level of chemical discharge is reduced and still the microbial control is high. This is in line with the global sustainability objectives and corporate environmental, social, and governance (ESG). Also, the green water treatment solutions are finding their way to the end users in industries such as power, food and beverage, and oil and gas to cut carbon footprints, meet energy standards and improve their sustainability ratings in the market.
