The global water desalination equipment market size was valued at USD 13.12 billion in 2020 and is expected to expand at a compound annual growth rate (CAGR) of 7.1% from 2020 to 2028. Factors including rapid urbanization, growing population, and rising water scarcity in several parts of the world are expected to drive the demand for water desalination equipment over the forecast period. During the COVID-19 pandemic, various construction sites and manufacturing companies were shut in 2020, resulting in hampering the demand for water desalination equipment. However, as the world has started returning to normalcy from the beginning of 2021, the demand for water desalination equipment is expected to witness growth as the governments of various countries are planning to invest in water treatment solutions to meet water scarcity issues.
The seawater segment led the market and accounted for over 55.0% share of the global revenue in 2020. The increasing scarcity of potable water is projected to act as the major factor for boosting the demand for seawater desalination. The rising importance pertaining to the treatment of seawater to save freshwater resources is expected to stimulate the demand for seawater desalination equipment.
In the desalination process, seawater is pumped into the plant and pretreated, wherein the suspended solids and other particles are removed through filtration. Post this stage, water is transferred for removing the salinity through reverse osmosis or thermal distillation. Rapid population growth, coupled with the depletion in freshwater reserves, has resulted in augmenting the demand for water globally, thereby complementing the market growth.
The brackish water segment is estimated to expand at a CAGR of 7.2% over the forecast period. The demand for brackish water desalination equipment is expected to be the highest in North America, South America, and Asia Pacific due to the presence of rich sources of brackish water that can be used for producing freshwater. The continuously growing population in these regions is expected to further increase the demand for freshwater, thereby boosting the market growth.
As compared to seawater, the main precedence of desalinating brackish groundwater is its high recovery rate. Seawater desalination yields approximately 50% freshwater, whereas brackish water yields approximately 90% freshwater. Moreover, the quantity of brine generated following brackish water treatment is less in volume and more concentrated than brine acquired after seawater treatment, making the procedure more environmentally benign.
