Zero Liquid Discharge (ZLD) Systems Market Analysis

Zero Liquid Discharge Systems Market Analysis

Based on product type, the zero liquid discharge systems market is segmented into two categories i.e. conventional and hybrid units. The conventional ZLDs are based on evaporation and crystallization operations. These plants helps in filtering highly soluble salts, such as ammonium and calcium chlorides, and certain heavy metal salts that can’t be crystalized without evaporating. The segment accounted for over 50% market share in 2018 and is expected to hold a major share in the future. The conventional ZLD disposes the solid wastes that can be used as by products that are reused or sold as an industrial processes.
 

Zero liquid discharge systems market has been classified into thermal based and membrane based technology. The membrane based segment will grow at a significant CAGR over 5.5% in the near future. The hybrid based ZLD process comprises a pre-treatment unit with brine filtration, trailed by a RO pre-concentration and further purification in a falling film MVR evaporator. This process is then concluded by a crystallizer and a solid separator, that produces potable water for the re-use in the manufacturing facility.
 

The zero liquid discharge systems market is further segmented into energy & power, food & beverage, chemicals & petrochemicals, pharmaceuticals, textile and some other end-users. The others segment consists of electronics & semiconductors, automotive etc. Chemicals & petrochemical industry is projected to grow with the highest CAGR around 6% in future. It is one of the highest water consuming industry globally. Therefore, evolving regulations regarding wastewater discharge and freshwater scarcity are augmenting the demand for ZLD and high water recovery solutions.
 

North America held a major chunk in the zero liquid discharge systems market owing to the gradual increasing population and industries coupled with surge in water & sewage treatment facilities. The segment is said to grow with a significant rate of over 5% in the projected timeframe.
 

Asia Pacific proved to be the fastest growing region in the global zero liquid discharge systems market and will continue to grow at a highest CAGR over 8.5% in future. Increasing industrialization and a large number of population is creating a big deficit in the amount of freshwater. The industries in the region are responsible for producing large amounts of sewage, that will enhance the regional market demand in the coming years.
