Zero liquid discharge can be defined broadly as a process for maximum recovery of water from a waste water source that would otherwise be discharged. This water is beneficially reused and the salts, and other solids contained in the waste water are produced and generally disposed in a landfill.
Moreover, how do you cure brine water?
Brine treatment involves desalinating the brine for reuse and producing a concentrated brine (lower liquid waste volume), or residual solids (zero liquid discharge). Brine disposal includes discharging brine to sewers, surface water, injection wells, or sending it to environmental service providers.
Correspondingly, what is MEE plant?
Multi Effect Evaporator [MEE]
Multi Effect Evaporator is defined as a apparatus for efficiently using the heat from steam to evaporate water. In a multiple-effect evaporator, water is heated in a sequence of vessels, each held at a lower pressure than the last. … Types of industrial evaporators: Falling Film Evaporator.
What is the concept of zero discharge?
The principle of “zero discharge” is recycling of all industrial wastewater. This means that wastewater will be treated and used again in the process. Because of the water reuse wastewater will not be released on the sewer system or surface water.
What is zero discharge effluent treatment?
Zero liquid discharge (ZLD) is an engineering approach to water treatment where all water is recovered and contaminants are reduced to solid waste. … ZLD is achieved by stringing together water treatment technology that can treat wastewater as the contaminants are concentrated.
What is zero liquid discharge Mcq?
Zero Liquid Discharge (ZLD) is a treatment process designed to remove all the liquid waste from a system. The focus of ZLD is to reduce wastewater economically and produce clean water that is suitable for reuse (e.g. irrigation), thereby saving money and being beneficial to the environment.
When was zero liquid discharge?
Which process is employed to gain sufficient head for the wastewater?
Which process is employed to gain sufficient head for the wastewater? Explanation: Pumping facilities may be employed to gain sufficient head for the wastewater to flow through the treatment works to the point of final disposal.
Why do I have zero liquid discharge?
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.
Why is ETP important?
ETP helps to purify wastewater generated from households as well as industry. The treatment process results in reusable clean water, saves your money as well as water and our planet.
