Water Treatment Market: Growth and Trends
According to the UN World Water Development report, almost half of the world's population faces water scarcity at least once each year. This highlights the importance of water treatment, which has proven to be an effective method for purifying water across different sectors.Water treatment typically operates by eliminating contaminants and impurities, thereby making water suitable for drinking, industrial purposes, and environmental preservation. The rising demand for efficient purification methods is propelling the use of high-performance adsorbents in both industrial and municipal water treatment settings.
To avoid fouling in filtration and desalination systems, antiscalants are commonly utilized to improve membrane durability and process effectiveness. Some of the primary benefits of water treatment include better water quality, prolonging equipment life, boosting operational efficiency, and adhering to health standards. It’s important to note that the adoption of water treatment in key industries is increasing rapidly due to the swift advancement of wastewater management technologies and heightened public awareness. Remarkably, over 2 billion individuals lack access to safe drinking water services.
The water treatment market is becoming an essential element in the global transition toward innovative water treatment solutions and digital advancements aimed at achieving greater availability of safe water. Innovations, such as cutting-edge membrane technologies, improve contaminant removal while lowering energy usage. Additionally, carbon-based purification techniques employ materials like activated carbon and graphene to efficiently capture a diverse array of pollutants, including micropollutants and organic substances. As a result, with ongoing technological progress in water treatment, including the integration of modular water treatment systems and analyses of the desalination market, the water treatment market is anticipated to experience significant growth during this forecast period.
Water Treatment Market: Key Segments
Market Share by Type of Treatment
Based on type of water treatment, the global water treatment market is segmented into membrane bioreactor (MBR), micro-filtration (MF), nano/ultra filtration (NF/UF), preliminary treatment, reverse osmosis (RO), sludge management techniques and others. According to our estimates, currently, the preliminary treatment segment captures the majority of the market share, owing to its essential function in improving the efficiency and effectiveness of subsequent treatment methods.However, the reverse osmosis segment is expected to grow at a higher CAGR during the forecast period. This can be attributed to its efficiency in eliminating contaminants and its versatility in handling various water sources, such as seawater and wastewater.
Market Share by Type of Application
Based on type of application, the global water treatment market is segmented into wastewater treatment, zero liquid discharge and others. According to our estimates, currently, the wastewater treatment segment captures the majority of the market share. This growth can be attributed to pressing the requirement for municipalities to ensure access to safe drinking water and to address the growing amounts of biological wastewater resulting from rapid urbanization and population increases.However, the zero liquid discharge segment is expected to grow at a higher CAGR during the forecast period. This growth can be ascribed to the rise in environmental regulations regarding water treatment and the increasing public awareness of the detrimental effects of wastewater, driving industries to implement sustainable water treatment solutions.
Market Share by End-Users
Based on end-users, the global water treatment market is segmented into commercial, industrial and residential. According to our estimates, currently, the commercial segment captures the majority of the market share.
