The increasing demand for renovation projects is anticipated to drive the growth of the deionized water system market in the future. Renovation projects involve efforts to enhance or update existing structures, which may include repairing damage, replacing outdated materials, or adding new features. Deionized water is commonly used in these projects as a cleaning and rinsing agent, effectively removing dirt, grime, and other contaminants from surfaces and serving as a cooling solution for equipment in renovation work. For example, in June 2024, Statistics Finland, a government agency in Finland, reported that households spent EUR 5.2 billion on renovating dwellings and residential buildings in 2023, marking a 2.7% increase from 2022. Thus, the rise in renovation projects is propelling the growth of the deionized water system market.

The burgeoning requirement for clean water is poised to steer the growth of the deionized water systems market in the foreseeable future. A fundamental catalyst is the escalating demand for purified water owing to contamination and scarcity issues in water sources. The imperative to treat wastewater for reuse or safe disposal is intensifying due to diverse factors such as population upsurge, climate fluctuations, industrial expansion, and rapid urban development. Projections from IntechOpen's report forecast a global population of 8.6 billion by 2030 and 9.8 billion by 2050. Additionally, a World Resources Institute report in August 2023 underscores an anticipated surge in water demand by 20% to 30% by 2050, attributed chiefly to escalated needs in domestic and industrial sectors. This amplifying thirst for clean water is expected to be a pivotal driver in the growth trajectory of the deionized water systems market.

Leading companies in the deionized water systems market are prioritizing the development of technologically advanced solutions, such as water circulation systems, to improve efficiency, lower operational costs, and adhere to stringent water quality standards. Water circulation systems are specially designed setups that facilitate the movement and recirculation of water within a specified area or process, promoting efficient water use while maintaining consistent temperature and quality. For example, in April 2023, Taiwan Semiconductor Manufacturing Company Limited, a semiconductor manufacturing firm based in China, introduced the Hot DI Water Circulation System 2 for wafer cleaning tools. This system aims to enhance energy efficiency and reduce water consumption in semiconductor manufacturing. It significantly improves wafer cleaning by cutting energy usage, saving around 388,000 kWh of electricity and 24,000 tons of pure water annually. The system's modular design reduces its footprint by 60%, optimizing cleanroom integration, and supports sustainable manufacturing by achieving an 80% reduction in DI water usage compared to previous models.

In May 2023, Xylem Inc., a leading water technology provider based in the United States, successfully completed the acquisition of Evoqua Water Technologies Corp for a total consideration of $7.5 billion. This strategic move positions Xylem to have a transformative global platform for addressing significant water challenges on a much larger scale. The combined strengths of both businesses create an unparalleled portfolio of products and services spanning the entire water cycle, effectively meeting the mission-critical needs of their customers. Evoqua Water Technologies Corp, also based in the United States, specializes in manufacturing products and solutions to ensure water quality, including items such as filter presses, intake rebuilds, and deionized water systems.
