Zero Liquid Discharge Systems Market Size, Share, Growth, Trends, and Global Industry Analysis: By System (Hybrid, Conventional), By Process (Pre-Treatment, Filtration, Evaporation/Crystallization), By Technology (Reverse Osmosis, Ultrafiltration, Evaporation/Crystallization), By End Use (Energy & Power, Chemicals & Petrochemicals, Food & Beverages, Textile, Pharmaceuticals, Electronics & Semiconductors, Others), and Region Forecast 2020-2031

Zero Liquid Discharge Systems Market size was valued at US$ 7,343.1 million in 2024 and is expected to reach US$ 12,831.5 million by 2031, growing at a significant CAGR of 8.3% from 2025-2031. The zero liquid discharge system is a water treatment purifying technique where the wastewater discharged from the industry is treated and purified which makes it reusable. A study says that about 93% of water can be recovered using a good zero-liquid discharge system. The advantage of zero liquid discharge system is that this technique can retain the by-products of water like salts. It is a cost-efficient method for the treatment of waste water. The scarcity of fresh water was always an issue all over the globe, the zero liquid discharge system can be used to desalinate the sea water and make it as drinkable water, these acts as a key driver to the market growth.

Many government regulations has been set and implemented strict guidelines and policies for the waste water discharge across the globe in order to control the wastewater discharge into oceans and sea, for instance, European Union water framework directives in European Union and Effluent limitation guidelines in Unites States. These regulatory bodies are set for protecting the environment from harmful waste water discharges from the industries. Increase in population, rapid urbanization, industrial revolutions, are the reason to cause scarcity of water which will lead to adoption of desalination of sea waters for drinking and domestic purpose. These are the reasons anticipated to fuel the growth of zero liquid discharge system market across the globe. The huge investments required in installation of zero liquid discharge system plant and the improper knowledge about the operating the zero liquid discharge system are the reasons anticipated to hinder the growth of the zero liquid discharge system.
