Desalination is a procedure that helps in separating dissolved salts and other minerals from seawater, brackish water, and groundwater & surface water. It is deemed as an alternative sustainable supply of freshwater with the requisite quality and quantity. The key advantage of desalination is that it can provide high-quality drinking water for consumption in areas of water scarcity. Desalination addresses diminishing freshwater supplies as the countries are looking for solutions to deal with water scarcity caused by climate change, industrial development, pollution, and population growth. Innovations in technology have improved energy efficiency, where larger economies of scale have also aided in reducing costs, thereby assisting in the growth of the overall water desalination market.

Zero liquid discharge is a developing water treatment strategy in which wastewater is recycled and purified, leaving slight to no sewage left over when the process is complete. Though the treatment requirements will mainly depend on the application, zero liquid discharge often involves ultrafiltration, evaporation, reverse osmosis, and several other membrane technologies. Rising megatrends in urbanization and industrialization are generating higher stress on the environment, involving the world’s freshwater resources. In several areas worldwide and especially in fast-developing and emerging economies such as India, rapid expansion in industries and manufacturing units are establishing a threat to water quality and enormous stress on water supplies. Concerns associated with water availability risks are expanded in areas inclined to water scarcity.

OVERVIEW A decentralized water and wastewater treatment systems help in providing flexibility and efficiency required to deal with water challenges across the globe. Decentralized water or wastewater treatment is the practice of setting water treatment facilities at the site of demand or supply. It is a sustainable and flexible alternative solution to the large treatment plants that need costly delivery and supply infrastructure. Water scarcity is one of the greatest challenges across the world, which affects not only the environment and human health but also local economies that depend on water for industry, agriculture, and business. Therefore, this generates the requirement for decentralized water treatment facilities to address the problems.
