What is a zero discharge system?
What is a zero discharge system?
Zero liquid discharge (ZLD) is a strategic wastewater management system that ensures that there will be no discharge of industrial wastewater into the environment. It is achieved by treating wastewater through recycling and then recovery and reuse for industrial purpose.
What is a zero liquid discharge system Mcq?
Zero liquid discharge (ZLD) is an engineering approach to water treatment where all water is recovered and contaminants are reduced to solid waste.
What does zero discharge actually refer to Mcq?
Explanation: Zero discharge usually refers to the treatment plant in which the reject from each part of the treatment plant is recycled. The reject is fed as the influent and once again treated.
What is MLD unit?

What is STP full form?

When was the zero liquid discharge invented?
Although the history of tighter regulations on wastewater discharge can be traced back to the US Government’s Clean Water Act of 1972, India and China have been leading the drive for zero liquid discharge regulations in the last decade.
What are tertiary filters?
Tertiary filtration removes suspended solids from secondary effluent at water resource recovery facilities (WRRFs). It is a polishing step following biological treatment and secondary clarification in preparation for disinfection, final discharge, or reuse.
How do you control TSS?
These are the best practices for reducing BOD and TSS that facility managers should know:
- Focus on removing TSS from wastewater first.
- Get a properly sized EQ tank.
- Control the pH of the waste stream.
- Install a modern plate pack DAF made of stainless steel or plastic.
- Use a regenerative turbine air dissolution pump.
