Major trends in the forecast period include innovations in membrane technology, adoption of iot (internet of things) and ai (artificial intelligence) technologies, development of innovative and sustainable desalination technologies, introduction of smart innovations, advancements in membrane technologies.

The rising water scarcity is expected to drive the growth of the desalination technology market in the future. Water scarcity occurs when the demand for water exceeds the available supply, which can result from physical limitations or insufficient infrastructure and management. Factors contributing to increasing water scarcity include population growth, climate change, water pollution, over-extraction of groundwater, inefficient water use, deforestation, land degradation, and conflicts over water resources. Desalination technology offers a sustainable and reliable source of freshwater, especially in regions experiencing severe water stress and scarcity. This technology plays a crucial role in promoting water conservation and implementing efficient water management practices, which are essential alongside desalination efforts. For instance, in March 2023, the United Nations Educational, Scientific and Cultural Organization (UNESCO), a specialized agency of the United Nations based in France, reported that the global urban population facing water scarcity is projected to reach between 1.7 and 2.4 billion people by 2050. Therefore, the increasing water scarcity is a significant driver of growth in the desalination technology market.

Key players in the desalination technology market are leveraging innovation to gain a competitive advantage. Notably, integrated plug-and-play reverse osmosis technology represents a significant advancement in this domain, offering a convenient and efficient solution for water treatment needs. This technology ensures the provision of high-quality freshwater while minimizing complexities in installation and operation. For example, in April 2022, Veolia Water Technologies, a renowned water treatment company based in France, introduced Barrel, an integrated plug-and-play reverse osmosis (RO) technology tailored for wastewater reuse and low-pressure RO applications. Barrel technology yields high-quality freshwater that adheres to water quality standards, featuring varying capacities ranging from 400 m3/day to 50,000 m3/day per unit. Additionally, it achieves a reduction in electrical consumption in the range of 0.05 kWh/m3 of freshwater produced, underscoring its efficiency and sustainability in addressing water scarcity challenges.

In May 2023, Xylem Inc., a US-based company specializing in developing innovative water solutions through smart technology, completed the acquisition of Evoqua Water Technologies for $7.5 billion.

The desalination technologies market also includes sales of pumps, membrane modules, pressure vessels, pre-treatment equipment, energy recovery devices, monitoring and control systems, and chemical dosing systems. Values in this market are ‘factory gate’ values, that is the value of goods sold by the manufacturers or creators of the goods, whether to other entities (including downstream manufacturers, wholesalers, distributors and retailers) or directly to end customers. The value of goods in this market includes related services sold by the creators of the goods.

The market value is defined as the revenues that enterprises gain from the sale of goods and/or services within the specified market and geography through sales, grants, or donations in terms of the currency (in USD, unless otherwise specified).

Desalination technologies are processes designed to eliminate salt and minerals from saline water, such as seawater or brackish water, in order to produce fresh water. These technologies play a crucial role in addressing water scarcity and ensuring a sustainable supply of fresh water for various applications, including drinking and irrigation.

The primary technologies employed in desalination include reverse osmosis (RO), multi-stage flash (MSF), and multi-effect distillation (MED). Reverse osmosis (RO) is a water purification method that utilizes a partially permeable membrane to eliminate ions, unwanted molecules, and larger particles from water. Desalination technologies draw water from diverse sources such as seawater, brackish water, river water, and others, catering to municipal, industrial, and other purposes.
