The industry induces market growth as well. According to China’s National Bureau of Statistics, the industrial sector grew by 7.2 percent between January and February of 2018, as compared to the same period a year earlier, exceeding economists’ forecasts of 6.1 percent. “Increasing pressure on the industry to improve water efficiency and reduce pollution discharges is expected to drive the demand for industrial water treatment technologies.” China’s 13th Five-year Plan on urban sewage treatment and water recycling facilities planning would aim to spend around 559 billion Renminbi (about 87.5 billion US-Dollar) or 0.75 percent of its GDP (gross domestic product) on its water treatment industry. “This is expected to increase the application of improved technology in industrial processes.”

Industrial wastewater treatment

The treatment of industrial wastewater is also a big business. According to a report, offered by MarketsAndMarkets (, the market size is expected to grow from 11.3 billion US-Dollar in 2019 to 15.0 billion US-Dollar by 2024 at a CAGR of 5.8 percent. As forecasted, biocides and disinfectants are estimated to be the largest type of industrial wastewater treatment. “The demand for biocides and disinfectant chemicals is comparatively higher, owing to its high requirement in wastewater treatment applications of all the major end-use industries considered in the study. Biocides are directly related to human physiology and have the ability to neutralize diseases causing microbes. Moreover, the increasing environmental regulations have fueled the demand for biocides and disinfectants in industrial wastewater treatment chemical market.” The zero liquid discharge (ZLD) mandate in the power generation industry plays a major role in enhancing the consumption of wastewater treatment chemicals.

The figures which are indicated by Reports and Data are slightly different. According to its current analysis, the global industrial wastewater treatment market was valued at 10.65 billion US-Dollar in 2018 and is expected to reach 16.60 billion US-Dollar by the year 2026, at a CAGR of 5.80 percent. As reported, the study ( covers in-depth analysis of industrial wastewater treatment and challenges faced by them. Industrial waste treatment involves various kinds of procedures used for treating wastewater that is produced by industries as an undesirable by-product. Once the treatment is over, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or surface water in the environment. Various types of contamination of wastewater require a variety of strategies to remove the contamination. Some of them include oil and grease removal, trickling filter process, removal of acids and alkalis, removal of other organics such as paints, pharmaceuticals, pesticides by vitrification and ozonation, removal of toxic materials such as zinc, silver, arsenic with the help of advanced oxidation process.

Demand for equipment

The demand for equipment will also grow. The size of the global equipment market for water and wastewater treatment was valued at 30.01 billion US-Dollar in 2018 and is estimated to expand at a CAGR of 3.68 percent by 2025, an analysis offered by Grand View Research found out (

The surge in investments in these types of equipment and facilities coupled with the growth of the oil and gas industries is projected to drive the market. “Increasing demand for clean water owing to rising population, industrialization, and rapid urbanization from emerging markets is resulting in a marked rise in the adoption of the equipment,” the India and US-based market research and consulting firm informed. “Increasing requirements for minimized global water footprint and optimum quality yields in emerging economies such as the Asia Pacific region are anticipated to drive the market.” Key equipment segments include membrane separation, disinfection, biological, and sludge dewatering. Membrane separation held the highest market share of 6.16 billion US-Dollar in 2018, Grand View Research wrote. “Rising awareness regarding the importance of nanofiltration and reverse osmosis for wastewater treatment applications is expected to play a crucial role in boosting the membrane separation product segment over the forecast period.” Biological equipment was the second-highest revenue-generating segment accounting 16.83 percent of the total market share in 2018.
