The “Global Zero Liquid Discharge Market, by Application (Power Generation, Oil & Gas, Chemicals & Petrochemicals, Mining & Metallurgy, Pharmaceuticals, and Others), by System Type (Conventional, and Hybrid) and by Geography (North America, Europe, Asia Pacific, Latin America, and Middle East & Africa) - Global Forecast to 2027”, is expected to be valued at US$ 1,253.08 million by 2027, witnessing a CAGR of 8.7% during the forecast period (2019-2027), as highlighted in a report published by Coherent Market Insights.


Zero liquid discharge (ZLD) is a wastewater treatment process, in which wastewater is decontaminated and recycled thereby attaining zero discharge at the end of wastewater management cycle. It is an advanced wastewater treatment technique that includes ultrafiltration, reverse osmosis, evaporation/crystallization, and fractional electro deionization. Zero liquid discharge system finds application plant discharge compliance, RO project, cooling tower blowdow, gasification water coal to chemicals (CTX) waste, IGCC wastewater treatment, and demineralization regeneration wastewater. Moreover, it is used in different industries such as power generation, oil & gas, chemicals & petrochemicals, mining & metallurgy, pharmaceuticals and more.

The global zero liquid discharge market is estimated to account for US$ 699.0 Mn in terms of value by the end of 2019

Market Driver

Growing adoption of this system in power generation is expected to drive growth of the global zero liquid discharge market during the forecast period

Growing urbanization around the world has increased the demand for power, in order to meet the energy requirements of ever-growing population. According to Coherent Market Insights’ analysis, power generation is growth of around 19. expected to witness robust 5% during 2012-2020. Moreover, coal and natural gas-operated power plants are expected to contribute to significant share to overall power generation during the forecast period. Furthermore, growing environmental regulatory policies are expected to drive the global zero liquid discharge market growth over the forecast period.

Market Opportunity

Retrieval of valuable compounds and minerals from residuals of wastewater is expected to pose lucrative growth opportunity for market players in the near future

Residuals remained after treating the wastewater that can be used to retrieve valuable minerals and compounds. Researchers have recovered sodium chloride and sodium sulfate as by-products of waste streams. Moreover, ZLD has been used in successfully recovering valuable and salable minerals from mining sector, which in turn, is expected to offer excellent growth opportunities for market players over the forecast period.

Market Restraint

Challenges regarding implementation complex wastewater systems are expected to restrain the global zero liquid discharge market during the forecast period

Industrial wastewater with high concentrations requires two-stage evaporation or crystallization process as a part of zero liquid discharge infrastructure. This, in turn, increase initial capital investment as well as operational cost. Moreover, this infrastructure is likely to require specialty components in order to accommodate special process. Increasing brine concentrations to reduce discharge volumes could, in certain cases, result either in scaling or acid formation, which is likely to result in increase in overall equipment corrosion. Furthermore, crystallization of complex wastewater produces salts such as calcium and magnesium chloride and hygroscopic salts that are challenging to handle. Therefore, industrial ZLD infrastructure requires evaluation of complex chemistry parameters including pH value, boiling point, solid formed, etc. These factors are expected to hinder the market growth over the forecast period.

Market Trends

  1. Strategic activities such as mergers and acquisitions among key players

Key players in the marker are involved strategic acquisitions and mergers, in order to expand their global presence. For instance, in June 2014, Degremont Industry, a subsidiary of Suez, acquired a stake in Evatherm.a Swiss engineering company that specializes in evaporation and crystallization technologies. Moreover, in January 2016, Veolia Water Technologies acquired Nuon Energie und Service GmbH from Vattenfall, in order to contribute to the development of Veolia’s industrial portfolio in Germany, through supply of parks with electricity, gas, water (drinking water, process water, and desalinated water), steam management services, and waste management brokering.

  1. Innovation of cost-effective methods is expected to continue during the forecast period

Key companies in the marker are focused on developing novel techniques in ZLD, in order to reduce capital investment and operational cost. For instance, in September 2015, Oasys Water launched Clearflo Complete Technology, a substitute to evaporator-based process the latter is substituted with a membrane brine concentrator. The process is cost-effective in terms of capital costs and energy consumption and produces higher water recovery.



Govt. of India – Environment (Protection) – Amendment Rules2015

  • In 2015, the Ministry of Environment, Forest & Climate Change of Indian Government released a draft announcement mentioning the standards for effluents from the textile industry. The clauses 6(B) and 6(c) of the notification covered provisions for ZLD - regulatory standards for the Indian textile industry were set which made it mandatory for textile units having wastewater discharge greater than 25 KLD to establish Zero Liquid Discharge (ZLD) effluent treatment plants.
