Growth Drivers

  • Surge in Adoption of Saline Water Treatment – In recent times many countries including the Middle East have adopted the process of saline water treatment or desalination process in order to accomplish the consumption of clean water. Many regions around the world are still dependent on desalination technology for meeting their water needs. Desalination is one of the most widely used processes for obtaining clean water and it uses coagulant substances, scale-inhibiting agents, and biocides on a large scale. The global water demand is estimated to increase by 55% in 2050 as per the report of the United Nations.
  • Growing Investment and Development in Industrialization - As a consequence of development in developed and developing countries crucial investment can be seen in various end-user industries such as oil & gas, paper & pulp, food & beverage, personal care, and others. For instance, China’s 40% global textile export in 2019 was attributed to private sector investment in the textile industry. The need for water treatment chemicals has increased as a consequence of development and investment in various industries.
  • Increasing Scarcity of Freshwater - The scarcity of water is one of the significant and major concerns prevalent in society faced by industries and people in general. As per the UNICEF report, around 4 billion people all across the world suffer from water scarcity. Industries require large amounts of water for the production process and generate large amounts of wastewater too. Increasing industrialization is expected to rise the demand for more water resources.
  • Rising Demand for Freshwater in Municipal and Industrial Sectors - Day-by-day increasing urbanization has raised the demand for municipal water treatment owing to rising demand for clean water and sanitization services. The escalating world population and economic development are boosting the demand for municipal and industrial water treatment which is further expected to propel the market growth.

Challenges

  • Availability of Alternative Water Treatment Technologies – Alternative Water treatment technologies such as ultrafiltration, RO, and UV disinfection is expected to limit the market growth in the upcoming times. Technological advancement minimizes the application of water treatment chemicals. Also, owing to increasing environmental regulations and measures end user industries are looking for more sustainable choices for water treatments.
