Water and Wastewater Treatment Equipment Market Dynamics:

Shortage of freshwater resources

As per the United Nations, water scarcity has a disastrous impact on global water consumption. Nearly 1200 million people, or about one-fifth of the world's population, live in areas where physical water scarcity and other drinking water-related challenges exist. An additional 1600 million people, or over a quarter of the world's population, face a lack of financial resources to acquire freshwater from various water sources. The depletion of water resources and water quality is a major concern in many developing countries around the world. In addition, nations with large populations, such as India and China, provide opportunities for the water and wastewater treatment equipment industry.

According to the World Health Organization, over 51% of the population in India and China did not have access to safe drinking water in 2012. The increasing growth of the world's population, combined with existing limited freshwater resources, has driven the development of a variety of technologies to satisfy the global demand for drinkable water. The technologies adopted are primarily geared at making the bulk of accessible water resources usable. As a result of these circumstances, water and wastewater treatment equipment manufacturers are focusing on alternate water sources such as desalinated and reused water. As a result, the prospects for water and wastewater treatment equipment manufacturers in the market for water and wastewater treatment equipment are likely to improve.

Costs of installation, equipment, and operations are all high.

Although there are numerous benefits to water treatment, the cost of installing water and wastewater treatment equipment is considerable. In the water treatment equipment market, the high cost of equipment and its operation acts as a constraining factor. For example. chemical treatment with chlorine gas demands large storage of the water to be treated. In developing countries, such infrastructure and equipment are scarce. For small-scale industrial applications, ozonation and UV equipment are extremely expensive. For undeveloped and underdeveloped countries, desalination equipment is extremely expensive. Similarly, the costs of operating and maintaining water purification facilities are high.

For example, a treatment system consumes a significant amount of energy to meet water processing and treatment needs. These issues are magnified in economically underdeveloped African countries, where over 45% of the population lacks access to safe drinking water. In addition, these countries lack basic infrastructure for water distribution and storage. This is expected to be a barrier to the global growth of the market.

Demand for energy-efficient innovative water treatment systems is increasing.

The global energy concerns range not only from the depletion of traditional energy reserves, but also from the environmental consequences of their extraction, treatment, emissions, waste disposal, and recycling. As a result, the demand for energy-efficient water treatment solutions is increasing for water treatment equipment. Membrane-based water treatment equipment plays a critical role in ensuring water and energy sustainability. The majority of these membranes have a wide range of uses in industrial operations. Desalination by RO, water and wastewater treatment by membrane reactors (MBR), lithium-ion battery packs, and membrane-based fuel cells are examples.

Membrane systems meet sustainability requirements in terms of eco-friendly parameters, land consumption, flexibility, and adaptability, to meet water and energy shortages. Also, membrane technologies must be enhanced in terms of cost and affordability, as well as energy consumption and efficiency. As a result, innovations in membrane equipment are required to make such development. These conditions are expected to create lucrative opportunities for membrane technologies and membrane equipment innovation in the future to address water and energy sustainability.

Aging Infrastructure.

The majority of privileged countries are confronted with the issue of aging infrastructure. These countries constructed water treatment facilities decades ago and continue to use outdated technology. Large sums of money are expected to be required to restore and upgrade these aging infrastructures. In the early years, developed economies Norway, Germany, China, and others built all of the necessary water infrastructures. In comparison, numerous emerging economies like Angola, South Africa, Egypt, and others, where many people still lack basic access to water, have just recently begun to build their water infrastructure.

Water and wastewater treatment systems have a service life of roughly 70 to 80 years, and many water and wastewater treatment plants have reached the end of their useful lifetimes in recent years. Furthermore, in some nations, water mains are not properly maintained. As a result, massive investments in many places are required to repair and replace the outdated water infrastructure. Although the anticipated rehabilitation or reconstruction of outdated water plants is likely to increase the availability of freshwater, the installation and upgrade of new equipment and systems to replace the old infrastructure are expected to be limited.
