What is the future of ZLD in Water Treatment?
The drive to collect and re-use as much wastewater as possible, by industry and municipalities is propelling significant growth, in the market for zero liquid discharge (ZLD) water treatment systems. As freshwater resources become scarce, and government authorities throughout the world, tighten their grip on any liquid waste products re-entering the environment, industries are turning to ZLD to satisfy a variety of constraints.
Yes, there is already a high demand for zero liquid discharge. As a result, Zero Liquid Discharge (ZLD) systems are the future of water treatment.
What is ZLD?
Zero liquid discharge is described as a procedure for recovering as much water as possible, from a wastewater source that would otherwise be discharged. This water is reused, and the salts and other particles in the wastewater are created, and typically disposed of in a landfill.
The reasons for ZLD include increased public concern about the impact of such releases on the environment, as water is a precious resource in many parts of the world. As a result of this worry, wastewater discharges are being more strictly regulated and limited. Even in the absence of a governmental push, many firms across sectors are mandating steps to minimize water discharge through recycling and reuse, as well as ZLD, in order to lower their environmental footprint, and increase sustainability.
Current attention in Zero Liquid Discharge Systems
Industries and government regulatory agencies from Europe, North America, to China and India, probably the world's largest industrial water consumers, are rapidly resorting to ZLD systems, to recover all liquid from wastewater or effluent, and return it to the system as clean and reusable water. These systems produce a totally dry, solid, and crystalline waste product, which reduces pollution, passes high regulatory criteria, and has the potential to reduce water-borne infections.
Currently, the Government of India has ordered, that a wide range of industries should migrate to ZLD treatment techniques. It has been legislated for industries ranging from fertilizer, brick, coffee, and textile facilities to sugar, paper, paint, and power plants.Although the transition is costly, it is predicted to save billions of dollars and conserve water supplies, for many years to come.
Finally, many enterprises are even attempting to recover usable elements from the crystallized solid waste, generated by the zero liquid discharge water treatment process. Industries can even recover lithium, potassium sulphate, gypsum, caustic soda, and sodium sulphate, once all of the water has been extracted, cleaned, and restored to the system.
Growth prospects for the ZLD Market
Experts in the industrial water treatment systems predict that the market for ZLD systems, would reach at least Rs. 9 billion by 2025. This modest estimate highlights the increasing constraints on companies and governments, to safeguard clean drinking water systems, as well as their own access to water resources that allow them to continue operating.
The ability to reuse over 98 % of the water that passes through their industrial system, allows them to face water resource instability with confidence, and a high-quality reusable water product.
The need for zero liquid discharge treatment is being driven by necessity!
Countries, companies, and other organizations responsible for the majority of the world's wastewater production, are aggressively seeking, acquiring, and constructing zero liquid discharge water treatment technologies, in order to recover virtually all of the water they consume.
