According to a report by Future Market Insights, the global water treatment market will increase at a compound annual growth rate (CAGR) of 7.4 percent during the period 2017­­–2027, to reach $88B in 2027. The level of acceptance for water treatment and its usage differs from various end-user requirements, which include industrial process and the usage of water in the residential, commercial and municipal sectors. To achieve the desired quality, water treatment systems often consist of three stages: pretreatment, treatment and tertiary/sludge water treatment. Enforcement of guidelines and management standards are expected to contribute to market growth.

Increasing awareness about conserving water, investments by governments and private enterprises in the industrial sector have helped the developing regions of Asia, Africa and Latin America. But a slow rate of return and a prolonged period of payback is likely to restrict investments in the water treatment market.

In system type, the reverse osmosis segment of water treatment has seen growth with an above-average CAGR due to the growing usage of saline/brine water and its treatment. By application, the process water treatment in the industrial sector and desalination has gained a major share of the water treatment market. Owing to these reasons, the industrial sector has been identified as the major consumer of water treatment by the market analysis in terms of usage, and this trend is expected to continue during the forecast period.

The Middle East and Africa, followed by Southeast Asia and the Pacific, have been identified as key markets that are propelling global market growth. This growth is in part due to growing water demand and a growing per capita water consumption.
