What does Zero Liquid Discharge mean?
Zero Liquid Discharge (ZLD) is an advanced system designed to prevent any liquid waste from leaving an industrial facility. Instead, the purified effluent and solid waste disposal form the
the core of such an environmentally-friendly operation towards sustainable industrialization thereby minimizing waste discharge and putting less strain on the natural water resources.
Explanation of ZLD and its Necessity
Essentially, ZLD comprises a collection of processes that make usable water from the effluents of industries. The remaining solids are either reused or safely discarded. This system is more important in water-scarce areas because it involves the conservation of water and reduction in pollution of the environment.
ZLD Systems – Their Purpose
Protecting the environment: It eliminates all the hazardous and polluting liquid waste, thereby destroying water bodies as well as damaging ecosystems.
Water recycling: It is an efficient method through which industries can recycle and reuse water, thereby reducing the amount of freshwater they consume.
Regulatory Compliance: The ZLD has become increasingly necessary to meet very high environmental laws and regulations.
Cost-effective: Although the cost involved is pretty high initially, in the long run, ZLD systems prove cost-effective by recycling water and decreasing waste disposal expenditure.
ZLD Treatment
Usually, the following stages signify the ZLD process:
Pretreatment: Removal of all the largest applications and any contaminants within the wastewater.
Evaporation: Concentration of the waste stream using methods like Multi-Effect Evaporation (MEE) or Mechanical Vapor Recompression (MVR).
Crystallization: Primary salts and some other residuals become solidified for disposal or reuse.
Condensation: Purified water is put back into use in the industrial system.
Classification of ZLD Evaporators
Goldfinch Evaporators is specialized in ZLD systems, a few of which include:
Multiple Effect Evaporators (MEE): Makes use of multiple stages to increase energy efficiency.
Mechanical Vapor Recompression Evaporators (MVR): Recycle the vapor through compression for maximization of energy savings.
Thermal Vapor Recompression Evaporators (TVR): It is a combination of mechanical and thermal processes for maximum efficiency.
How Does a ZLD Treatment System Work?
Characteristically, ZLD Treatment Systems treat waste streams by these methods: Filtration, Evaporation, and Crystallization. The process recycles purified water separately from solid waste and achieves zero liquid waste discharge for sustainable industrial operations.
Primary Components of Basic ZLD Treatment System
Filtration Units: Primary treatment of wastewater.
Evaporators: Concentration of waste streams.
Crystallizers: Dissolved substances are converted into solids.
Condensers: Recoverance of clean water for reuse.
Application of Zero Liquid Discharge in Industries
ZLD is primarily applicable to industries like power generation, chemicals, textiles, and others. Such industries, having a high volume of wastewater, recover resources and act on the global sustainability agenda.
ZLD Regulations and Guidelines in India
Zero liquid discharge is a compulsory mandate in many water-scarce regions, particularly for highly polluted effluents. Hence, the state has put in place provisions to enforce strict compliance by all facilities to encourage sustainability in these industries.
