ZLD is a wastewater treatment process in which all wastewater purified and recycled; Therefore, Leaving zero discharge at the end of the treatment cycle.
An efficient and well-designed ZLD Should be able to:
- Eliminating liquid Wastewater Discharge
- Generating solids for landfill disposal or reusing(treat and retrieve valuable byproduct from your waste)
- Recovering around 95% of your liquid waste for reusing
- Allow for required chemical volume adjustments
Major drive for ZLD Implementation:
- Stricter Environmental regulation
- Increasing cost for wastewater disposal
- Water Scarcity
- Increased public environmental awareness
ADVANTAGE
Zero liquid discharge for treating industrial water, provide numerous benefits. Listed among these benefits are:
- Optimized industrial water cycles
- Consistent water supply and consistent quality
- Reduced dependence and use of municipal water sources
- Compliance with stringent legislative and environmental regulations
- Sustainability
DISADVANTAGE
- Use of higher amount of chemical in wastewater treatment
- Increase in energy usage
- Generation of enormous amount of hazardous sludge and other solid waste
- Impact on cost of processing (Implementing ZLD pushes up cost by 25-30%)
