Water Treatment Systems Market Segmentation:

Installation Segment Analysis

In water treatment systems market, point-of-use segment is projected to account for revenue share of around 58% by 2035. The segment growth is propelled by the increase in water contamination. PoUs are essential for the treatment of drinking water in underdeveloped areas because they are easy to use, affordable, require little maintenance, and are grid-independent.

According to a 2023 UNESCO report, 3.6 billion people (46%) do not have access to securely managed sanitation, and 2 billion people (26%) do not have access to safe drinking water globally. These systems are of great use in health care settings, especially for the treatment of patients who have an impaired immune system. The segment for point-of-use water treatment systems is expected to increase significantly over the forecast period, as a result of various factors such as population growth, increased awareness about the benefits of water treatment, and technological advances in this area.

Technology Type Segment Analysis

By the end of 2035, reverse osmosis segment is anticipated to dominate water treatment systems market share of around 35%. To remove 99% of water impurities while offering the same quality as drinking water, RO systems are using innovative membrane filter technology. Therefore, water purification is frequently performed by such systems. They're considered to be the most efficient way of treating hard water. The reverse osmosis system is typically connected to a mechanical and activated carbon filter.

RO water purifiers are available in a variety of sizes and shapes, including wall-mounted, tabletop, under-sink, and under-the-counter models. To support the growth of this sector, reverse osmosis technology has a higher efficiency, a higher capacity, and a lower economic cost compared to other technologies.

According to a National Institutes of Health report, the groundwater in NCP has sufficiently high removal or rejection efficiency (91–98%) for important elements including TDS, hardness, alkalinity, silica, and significant ions (Ca2+, Mg2+, Na+, Cl−, and SO42−) for the RO stations now in operation.
