A Global Market Outlook of Effluent Treatment Industry
Effluent is defined by the United States Environmental Protection Agency (EPA) as wastewater (treated or untreated) that flows out of a treatment plant, sewer, or industrial point source. Generally, effluent refers to wastes discharged into surface waters.
The use of large amount of water in a number of industries generate a large quantity of wastewater. Wastewater generated from different industries have different characteristics. The wastewater generated from food industries is generally biodegradable and less harmful. In contrast, those generated from a chemical and oil plant may be more toxic and non-biodegradable. Regardless of industries, the treatment of wastewater is necessary to minimise the pollution to environment. Consequently, every industry requires an effluent treatment plant. The technologies and chemicals used in treatment of wastewater may differ in different effluent treatment plant. The types of chemicals used in the treatment of wastewater include coagulants, flocculants, disinfectants, and neutralizing agents. Coupled with strict government regulations, the global demand for effluent treatment plants has increased tremendously.
The equipment and chemicals used in treatment of wastewater forms the largest segment of global wastewater market. The market in North America is projected to dominate the effluent treatment plant market due to the number of projects involving shale gas production. In the shale gas production, water is heavily used for hydraulic fracturing and the wastewater generated has to subsequently be treated.

In many developing countries, the governments also aid in establishing common effluent treatment plants (CETPs) where companies in the same industry can treat their wastewater together. An example is the CETPs in Maharashtra, India. This clustering generates traded interdependencies and possibly, untraded interdependencies.
In China, the rapid demand for water recycling technologies are driving the growth of the market. The market is projected to reach $1.18 billion by 2020. Weather pattern is also a strong impetus for the growth of this market. In India, unpredictable rainfall patterns and contaminated groundwater have had an impact on the growth of wastewater recycle and effluent treatment plants. The market for treatment of wastewater in Mexico is growing at a rate of around 8% due to the rapid industrialization of the country.

The revenue for global wastewater market in 2014 was approximately $185 billion. Mr Karan Chechi, the research director of TechSci Research, predicted that the global wastewater market will grow at a compound annual growth rate (CAGR) of about 10% between 2015 to 2024. The strong awareness of water conservation, environmental protection, and strict government regulations will continue to catalyse the growth of wastewater market.
