Market Overview

The Global Market For Wastewater Treatment Chemicals is comprised of various producers selling their associated products to remove contaminants from various types of wastewater before it can then be reused either as is or after further treatment. The continuing growth of this sector is mainly due to the increased volumes of industrial effluent generated by industry, increasingly stringent effluent discharge standards being enforced, an overall increased governmental focus on providing clean water through various outreach programs, a growing trend toward sustainable management of water resources, and a move toward using increasingly advanced, efficient, and environmentally friendly chemicals for treating industrial effluents.

The market offers opportunities from rapid urbanization, increasingly stringent governmental discharge regulations, having many large infrastructure projects planned or underway, the increasing volume of industrial water being discharged each year, emerging contaminants such as PFAS, and the development of innovative and environmentally sustainable technologies to improve treatment efficiency. The Government of India has committed to spending in excess of 20,000 crores, approximately 2.7 billion, on sewage treatment infrastructure under the Navami Gange Programme of the National Mission for Clean Ganga. These expenditures will be used to construct and renovate hundreds of sewage treatment plants to help reduce the pollution of the Ganga River basin. In addition, this governmental programme is slated for continued funding to upgrade sewage treatment plants and continue projects that focus on wastewater treatment and ecosystems to revitalize rivers. This amount of additional governmental funding for sewage treatment will directly or indirectly impact the demand for coagulants, flocculants, and other water and wastewater treatment chemicals.
