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.
When was the ZLD invented?
Nassef built a ZLD prototype in 2004 from washing-machine parts and a five-gallon paint bucket. The current version, his 11th update, uses only as much energy as ten 100-watt lightbulbs, sterilizes waste without any of the harsh chemicals of other portable toilet-waste-disposal systems, and can be scaled up or down.
What is a ZLD power plant?
Wastewater Treatment for Power Plants: Considering Zero Liquid Discharge. Implementing Zero Liquid Discharge (ZLD) can help solve these issues. The ZLD process eliminates discharge at the end of the wastewater treatment cycle and allows the processed water to be reclaimed and reused in a variety of advantageous ways.
What do you mean by ETP?
Exchange-traded products (ETP) are types of securities that track underlying security, index, or financial instrument. The share price of ETPs come from the underlying investments that they track. ETPs are usually a low-cost alternative to mutual funds and actively-managed funds.
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.
Why is Zld needed?
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.
What is Mee and ATFD?
SALT DRYER & ATFD UNIT It Is used to evaporate the residue water from MEE concentrated liquid and generate dry salt for dispose. MEE concentrated liquid have large amount of water content which is not possible to dispose so salt dryer is used after MEE to reduce water content from MEE concentrated liquid.
Why is evaporator used?
An evaporator is a device used in a process to turn the liquid form of a chemical substance, such as water, into its gaseous form – vapor. The liquid is evaporated, or vaporized, into a gas form of the targeted substance in that process.
What does zero discharge actually refer to with respect to water supply and sanitation?
