zero liquid discharge technique, zero liquid discharge case study, zero liquid discharge desalination

Zero Liquid Discharge (ZLD) is a treatment approach that clears a system of all liquid waste. ZLD water treatment aims to produce water that is suitable for daily consumption, while affordably reducing wastewater.

A sophisticated treatment method known as a zero-discharge system uses fractional electro-deionization, evaporation, reverse osmosis, ultrafiltration, and other processes.

Why is a sewage system with zero liquid discharge necessary?

Numerous industries, such as mining, oil and gas, electricity, and others produce a sizable volume of wastewater that needs to be treated. Wastewater is often released by a plant outfall to a surface water body, like an evaporation pond, or, in extremely unusual circumstances, deep well injection.

These activities pose serious environmental concerns among the general public, in many regions of the world since water is a valuable resource. As a result of these worries, numerous businesses have implemented ZLD techniques, to decrease their environmental impact and increase sustainability.

ZLD has been necessary in India over the past ten years because to the significant industrial effluent pollution, of local waterways that has harmed their rivers and lakes. The necessity for ZLD in India has grown as a result of the high costs, associated with wastewater disposal at inland plants.

ZLD: System technologies

1. Falling film brine concentrators

2. Forced Circulation Crystallizer

3. Horizontal Spray Film Evaporator

4. Hybrid Systems with Membrane Pre-Concentrators

5. Biological Treatment

6. Solid waste management

Applications and advantages of a zero liquid discharge system

Valuable materials are recovered from wastewater so they can be sold or used again, in industrial processes.

Examples:

1. Important potassium sulfate fertilizer is produced by salt mines.

2. Lower the price of treating wastewater from coal mines by extracting pure sodium chloride, which may be used as road salt.

3. Lowers waste management costs by reducing wastewater volume.

4. On-site water recycling lowers water input requirements, while still meeting treatment standards.

5. Lower the costs involved with truck transportation for off-site disposal, as well as the accompanying environmental dangers.

ZLD system designs factors

1. The contaminants in the discharge stream

2. The volume of the dissolved substance

3. Required design flow rate

Chemicals that should be avoided in zero liquid discharge systems

Water chemis?try needs to be carefully considered when using the zero liquid discharge technology. The following substances make up a zero liquid discharge system's chemical composition:

· Sodium

· Potassium

· Calcium

· Magnesium

· Barium

· Strontium

· Silica

· TDS/TSS

· COD/TOC/BOD

· pH

· Chloride

· Fluoride

· Sulphate

· Nitrate

· Phosphate

· Ammonia

· Boron

· Alkalinity

· Grease and oil

Design of the ZLD system

No matter how many wastewater sources there are, a ZLD system normally comprises two phases.

1. Pre-concentration: Brine obtained primarily through the use of membrane brine concentrators, is pre-concentrated. The following techniques suggest that these technologies could recover 60 to 80 percent of the water.

2. Evaporation/Crystallization: The subsequent evaporation process gathers and directs, all leftover water for re-use. The remaining waste is then delivered to a crystallizer, which boils every drop of water until all of the contaminants have crystallized, and have been eliminated as a solid by filtering.
