What is meant by 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 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.

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 zero discharge in wastewater treatment?
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.
How does ETP work?
The principle of operation of ETP is Physico-Chemical treatment followed by Polishing Treatments like –Sand Filtration, Activated Charcoal treatment (Adsorption), Ozonisation (Chemical Oxidation), Ultra Filtration (UF), Reverse Osmosis (RO) and evaporation (If required). Features : Semi-automatic Operation.
What is ETP & STP?
ETP( Effluent Treatment Plant) STP ( Sewage Treatment Plant)
What is ETP and why it is important?
Effluents from food and beverage factories contain degradable organic pollutants. Since industrial waste water contains a diversity of impurities and therefore specific treatment technology called ETP is required.
