Using a technical approach to water treatment known as Zero Liquid Discharge (ZLD), all water is recovered and impurities are converted to solid waste. While, many water treatment technologies aim to enhance freshwater recovery and minimize waste, ZLD is the most difficult goal to achieve because recovery costs and difficulties rise, as wastewater concentrations rise.

In this method, the plant doesn’t release any liquid effluent into surface waters, effectively eradicating all associated environmental pollutants. In addition to this, a ZLD process effectively uses wastewater treatment, recycling, and reuse, which helps with water conservation by reducing the need for fresh water.

Let’s talk about some of the benefits of a zero liquid discharge plant.

Steps involved in Zero liquid discharge system

The following steps are involved in ZLD process:

1. Pre-treatment

TSS (Total Suspended Solids), COD (Chemical Oxygen Demand), and turbidity are all reduced with pretreatment. Other wastewater treatment procedures can be utilized when the TSS, COD, and turbidity of treated wastewater have been removed or significantly reduced.

2. Concentration

Reverse osmosis (RO), electrodialysis (ED), or a combination of RO and ED, are common membrane technologies used to concentrate dissolved solids in the ZLD system. We can recover more than 98% of the treated water with the use of ED technology, or the above-mentioned RO + ED combination.

3. Thermal-treatment

The final step of the ZLD process, known as thermal treatment, typically consists of an evaporator and a crystallizer. Crystalline salts such as NaCl and Na₂SO₄ are produced as a result of this procedure.

These salts can be purchased to be processed further. Any useless solid waste is dumped to landfills under management. Condensate made from evaporated water can be used again.

Now, let’s discuss about the advantages of zero liquid discharge plant!

The use of zero liquid discharge plants as a significant wastewater management tactic, to decrease water pollution and increase water availability is expanding globally.

The principal advantages of ZLD are as follows:

• The possibility of recovering resources from wastewater is a crucial justification for zero liquid discharge. Because, ZLD can sell the solids created or reuse them as part of their industrial process, some organisations target ZLD for their trash.

• Whatever the organization’s reasons for aiming for zero liquid discharge, doing so indicates sound business practises, corporate accountability, and environmental stewardship.

• Operating an internal ZLD plant can save disposal costs, increase water reuse, and reduce greenhouse gas emissions from off-site trucking, which has a smaller negative impact on regional ecosystems and the climate.

• Industrial effluent has severely contaminated many significant rivers, and many nations, like India, have established legislation requiring zero liquid discharge. The high costs of wastewater disposal at inland plants have pushed many countries towards zero liquid discharge.

• It also enables maximum water recovery.

• It produces a useful product for retail sales and additional processing.

• Many environmental problems are resolved.

• Decreases reliance on nearby water sources.

• Significantly lowers the likelihood of punishment for discharged waste under the law.

Applications of zero liquid discharge plants

There are certain industrial applications of zero liquid discharge:

• Breweries
• Tanneries
• Chemical
• Paper industry.
• Textile industry.
• Power industry.
• Petrochemical industry.

A technological approach to purifying water in which all water is recovered and contaminants are converted to solid waste is known as “zero liquid discharge.” ZLD is the most challenging goal to attain since recovery costs and challenges increase as wastewater concentrations grow. Although many water treatment systems strive to boost freshwater recovery and minimise waste. Concentrations of salinity, organics and scaling compounds, all rise, adding to the expense of regulating these increases. Combining water treatment technologies that can handle wastewater when the toxins are concentrated allows for ZLD.

With so much benefits to offer from a ZLD one becomes curious to know about it keenly and contribute to the environment. Let’s settle your curiosity and know the zero liquid discharge more elaborately!

Zero liquid discharge plant:

You can turn your waste into no-waste by using zero liquid discharge plant. These sturdy, portable systems handle wastewater from industrial processes and salvage priceless goods from recycling procedures. Materials are successfully separated from water or other wet materials, and they are then converted to solid waste that may be sold, reused, or disposed of more effectively. ZLD systems are advantageous to the environment and your bottom line, and they are simple to modify to match your changing demands and regulatory requirements.

A ZLD treatment system, as the name indicates, uses cutting-edge modern water treatment procedures to reduce liquid waste at the conclusion of your industrial process to zero. Zero Liquid Discharge treatment system that is effective and properly thought out should be able to:

• Adapt the fluctuations in the flow and contamination of waste
• Allow for necessary changes to chemical amounts
• More of your liquid waste can be recovered for reuse.
• Treat your waste to recover valuable byproducts.
• Create a solid or dry cake for disposal.

Your business will be able to comply with strict effluent standards and Electric Power Generating Effluent Guidelines with the use of a ZLD treatment system. Just bear in mind that the criteria for your facility will change depending on whether you are discharging to the environment under a National Pollutant Discharge Elimination System or into a publicly owned treatment works.

What components make up a fundamental ZLD plant?

The precise parts of a ZLD treatment system will primarily rely on

(1) Amount of dissolved material present in the waste,

(2) Flow rate needed for the system, and

(3) What particular pollutants are there. But often, a fundamental ZLD treatment system consists of some combination of:

• A clarifier or reactor to remove hardness, metals, and silica
• Chemical feed to aid in the coagulation, flocculation, or precipitation of any metals and suspended solids
• A filter press beside an evaporator or after pretreatment to concentrate secondary solid waste.
• UF: Ultrafiltration (UF) to eliminate any traces of suspended particles that are still present and stop fouling, scaling, and/or corrosion later in the treatment process.
• RO: Brine concentrators to further concentrate the reject RO stream or reject from electrodialysis to further concentrate the dissolved solids removed by reverse osmosis (RO), which removes the majority of dissolved solids from the water stream in the main phases of concentration.
• Evaporator: In the final stages of waste concentration before the crystallizer, an evaporator is used to vaporize access water.
• Crystallizer: Using a crystallizer, boil out any residual liquid to produce a dry, solid cake that may be disposed of.

These standard components are sufficient depending on the requirements of your plant and process, but if your plant needs system that offers a little bit more customization, you could need to add additional features or technologies. ZLD is a highly customized process because of the wide range of industries it is used in and the many waste streams it produces, and these add-ons will vary depending on your facility’s specific requirements.

Due to urbanization and globalization, water demand is rising day by day, despite its scarcity. Wastewater from industries including power, oil and gas, pharmaceuticals, and chemicals contains harmful and toxic compounds, solid waste, and organic waste, which further harms the environment.

In fact, many government and commercial organisations like Netsol Water Solutions, have designed plans to install ZLD Plants, to reduce water waste, which will aid them in developing a sustainable environment.

Zero Liquid Discharge plant

A method known as zero liquid discharge (ZLD) aims to reduce the amount of liquid waste, generated at the end of an industrial operation to zero. It is being utilized increasingly, and frequently as a result of tighter discharge limitations and it can be especially helpful, in areas with limited water supplies or where waterways are protected.

By using it, your company can avoid paying large fines if it violates any local effluent standards.

Zero liquid discharge plant manufacturers-who to trust?

Finding a ZLD system for your plant that is economical and ecologically beneficial can be difficult, especially as effluent standards become more stringent and your alternatives for discharge treatment are constrained. In order to help you with a new or upgraded ZLD water treatment system, you may be asking which businesses are the best in the field of zero liquid discharge equipment and technology.

Although, there are a number of manufacturing units that provide ZLD system facilities, but the best production site of Zero Liquid Discharge (ZLD) facility is Netsol Water Solutions. Our firm has reduced water use while producing its products and assured that no liquid waste is produced, with the help of the ZLD technique.

Components of our ZLD Plants

The zero liquid discharge plant provided by Netsol Water Solutions utilizes a 100 percent supply, of effluent-treated water from sewage treatment plants (STP) and effluent treatment plants. It is then processed using a mix of methods, including Agitated Thin Film Dryer (ATFD), Reverse Osmosis, and Membrane Bio-Reactor (MBR).

The final result is the permeate, which is of good quality water, and is reused in fume hoods, boiler feed, and cooling tower makeup water, without being dumped into the sewage. This puts the wasted water to good use. Apart from this, by the process of evaporation, the rejected water is transformed into solid waste residue, which is then disposed of as hazardous waste (as per the regulatory norms).

An industrial reverse osmosis (RO) plant is a water treatment facility that uses the reverse osmosis process, to remove harmful compounds and pollutants from water. Here, the water with the higher concentration of dissolved ions is subjected to external pressure, which causes the water to pass through the semi-permeable membrane in the opposite direction.

Permeate, or well-treated product water, is the water that passes through the semi-permeable membrane. Reject, brine, or concentrate water is the term used to describe the water that is left behind the membrane, after the dissolved and suspended solids have been removed. The Industrial RO plant operates in this manner.
