Water and wastewater treatment is becoming increasingly important in many countries and regions worldwide. Various European countries are progressing toward wastewater treatment targets and the protection of sensitive water systems. Collecting and treating wastewater is essential for reducing risks to human health and the environment, particularly for rivers, lakes, and coastal waters. According to the European Environment Agency (EEA), 81% of urban wastewater is collected and treated in line with EU standards in Europe. Country analysis based on the implementation of EU rules on wastewater treatment shows that the EU member states are significantly applying the rules, and the compliance rate has slightly increased in recent years. As per the data from the EEA, Austria, Germany, Luxembourg, and the Netherlands treat 100% of urban wastewater in compliance with the EU Directive's requirements, and 10 additional countries have reached over 90% compliance rate. In France, 90% of the urban wastewater is treated according to the requirements of the Urban Waste Water Treatment Directive (UWWTD). This is above the EU average of 76%. According to the Environmental Protection Agency (EPA), wastewater treatment facilities in the US process ~34 billion gallons of wastewater every day.

In Southeast Asia, growing water contamination, increasing demand for clean water, stringent government regulations on water and wastewater treatment, and increasing industrial waste discharge into water bodies propel the requirement for initiatives to expand wastewater treatment facilities across the region. In Singapore, the government has developed an advanced system to treat sewage involving a network of tunnels and high-tech plants. As of 2022, recycled wastewater can meet 40% of Singapore's water demand, and it is expected to rise to 55% by 2060, according to Southeast Asia Infrastructure. Singapore is planning to invest ~US$ 7.4 billion in upgrading its water treatment infrastructure. In Myanmar, rapid economic growth accompanied by urbanization has led to significant challenges, especially in terms of waste management and treatment. To address issues of wastewater treatment and management, the Ministry of Natural Resources and Environmental Conservation-with the assistance of the International Environmental Technology Centre of the United Nations Environment Programme and the IGES Centre collaborating with UNEP on Environmental Technologies-launched the National Waste Management Strategy and Master Plan (2018-2030) in Myanmar. Water and wastewater treatment is a major application sector for calcium hypochlorite. Calcium hypochlorite is highly used to disinfect swimming pool water, drinking water, and industrial water. Thus, the rising focus on water and wastewater treatment activities in various countries across the world drives the demand for calcium hypochlorite.

By form, the market is segmented into powder and granule. The powder segment held the largest share of the market in 2024. Calcium hypochlorite in powder form is widely used in a variety of applications, such as water treatment, bleaching agents, disinfection and sanitization, and industrial cleaning and sterilization. Calcium hypochlorite is highly used to disinfect drinking water. It is effective in killing bacteria, viruses, and other pathogens, ensuring safe drinking water. It is also widely used in pool sanitation to control bacteria, viruses, and algae in the water. The powder form of calcium hypochlorite is particularly convenient for bulk treatment. It also finds applications in disinfecting wastewater and controlling the growth of harmful microorganisms in sewage treatment plants.

In terms of application, the market is categorized into water treatment, house cleaners and detergents, agrochemicals, pulp and paper, food and beverage, and others. The water treatment segment held a larger market share in 2024 and is expected to register the highest CAGR from 2025 to 2031. Water and wastewater treatment is a major application sector for calcium hypochlorite. Calcium hypochlorite is easier and safer to use than other chlorine sources for water treatment. Calcium hypochlorite is used to disinfect swimming pool water, drinking water, and industrial water. It effectively kills parasites, bacteria, viruses, and other microorganisms in the water, thus ensuring the safety of the water and its quality. Calcium hypochlorite aids in oxidizing organic matter and odor substances in water, which helps remove pollutants in water and improve the taste and quality of water. In addition, calcium hypochlorite is also used as a bleaching agent, which is effective in removing impurities and colors when treating water sources that contain colors or stains.

Calcium hypochlorite offers several advantages for water treatment compared to other disinfection methods, such as ozone. To create a solution, solid calcium hypochlorite is dissolved in water. In contrast, ozone must be generated using a specialized ozone generator.

The market is segmented into five main regions-North America, Europe, Asia Pacific, Middle East & Africa, and South & Central America. Asia Pacific is estimated to register the fastest CAGR in the global calcium hypochlorite market from 2025 to 2031. The calcium hypochlorite market in Asia Pacific witnessed significant growth due to the growing textile production in the region. According to the Asian Development Bank, as the population in the Asia Pacific is increasingly shifting to urban areas-2.5 billion or 55% of the population is predicted to live in urban areas by 2030-water demand is projected to increase by nearly 55%. According to the World Trade Statistical Review 2022, China and Vietnam are among the world's largest textile exporters. According to the Observatory of Economic Complexity (OEC), Chinese textile exports accounted for US$ 297 billion in 2024-2025. According to the US Department of Agriculture, Vietnam yarn exports between January 2024 and October 2024 increased by 4% year-on-year, accounting for 1.5 million metric tons.

The growing emphasis on environmental protection has led to a rise in demand for calcium hypochlorite. For instance, the Asian Development Bank aims to expand initiatives on wastewater reuse and wastewater management, including hygiene and sanitation. It also aims to expand the region's capacity for wastewater management through increased financing, rising hygiene awareness, and stronger advocacy. Thus, the growing end-use industries create lucrative opportunities for the calcium hypochlorite market in the region.
