Product Details

ZLD Plant Manufacturers in India – Zero Liquid Discharge Plant

V Aqua Water Treatment Company offers customized Zero Liquid Discharge (ZLD) Plant solutions in India for industries looking to recover wastewater, reduce freshwater consumption and minimize liquid discharge. Our ZLD systems can be designed by integrating technologies such as ETP, STP, CETP, UF, RO, MEE, MVR, ATFD and evaporation systems according to wastewater characteristics and project requirements.

ZLD plants are widely used in water-intensive industries including textile, chemical, pharmaceutical, paper, food processing, steel, power generation and other manufacturing sectors.

What Is a ZLD Plant?

A Zero Liquid Discharge Plant is an advanced wastewater treatment and water-recycling system designed to recover maximum practical water from wastewater while concentrating the remaining dissolved salts and contaminants into a manageable solid or semi-solid residue.

Unlike conventional wastewater treatment systems that may discharge treated water, a ZLD system is designed around the principle of:

Wastewater Treatment → Water Recovery → Concentration → Evaporation → Solid Residue

The recovered water can be reused for suitable industrial applications, helping reduce dependence on freshwater sources.

The final ZLD configuration depends on:

• Wastewater flow rate

• TDS and conductivity

• COD and BOD

• Suspended solids

• Hardness

• Chloride and sulphate

• Silica

• Chemicals and heavy metals

• Required water recovery

• Final water reuse application

• Available steam and electricity

• Space availability

The exact process is customized according to the wastewater analysis and required recovery.

ETP + UF + RO – ZLD ETP Plant

An ETP + UF + RO ZLD Plant is designed for industrial wastewater treatment and water recovery.

The ETP removes major pollutants and prepares the wastewater for advanced membrane treatment. UF provides additional filtration before RO, while RO separates purified permeate from concentrated reject.

The RO permeate can be reused for suitable applications, while the RO reject can be sent to an evaporation system for further concentration.

Typical Process

Industrial Effluent → ETP → Filtration → UF → RO → Permeate Reuse → RO Reject → Evaporation → ATFD / Crystallizer

This configuration can be suitable for:

• Textile industries

• Chemical industries

• Pharmaceutical industries

• Paper industries

• Manufacturing units

• Metal processing

• Food processing

STP + UF + RO – ZLD STP Plant

For large residential, commercial and institutional projects, treated sewage can be further polished using UF and RO.

A typical system can include:

STP → Tertiary Treatment → UF → RO → Reuse

Where complete elimination of liquid reject is required, additional concentration or evaporation technology can be incorporated.

Potential applications include:

• Hotels

• Hospitals

• Residential complexes

• Commercial buildings

• Educational institutions

• Industrial campuses

• Large facilities

Recovered water can be used for suitable non-potable applications such as flushing, gardening, cooling and other utility requirements after confirming the required water quality.

CETP + UF + RO – ZLD CETP Plant

A Common Effluent Treatment Plant (CETP) is designed to treat wastewater generated by multiple industries, generally within an industrial cluster.

A ZLD CETP can integrate:

Wastewater Collection → CETP → Tertiary Treatment → UF → RO → Evaporation → Final Concentration

CETP-based ZLD systems require detailed wastewater characterization because different industries can contribute different pollutants and concentrations.

These systems can help industrial clusters improve:

• Wastewater treatment

• Water recycling

• Freshwater conservation

• Centralized effluent management

• Environmental performance

• Waste reduction

ETP or STP + Water Evaporation ZLD Plant

For wastewater streams with high dissolved solids or difficult-to-treat contaminants, evaporation can be incorporated into the treatment process.

A typical configuration may be:

ETP / STP → Filtration → Evaporation → Condensate Recovery → Concentrated Residue

Depending on the wastewater characteristics, RO can also be installed before evaporation.

Thermal evaporation can be considered when:

• Wastewater contains high TDS

• RO reject volume needs to be reduced

• Additional water recovery is required

• Concentrated brine needs further treatment

• Conventional treatment is insufficient

RO + MEE + ATFD ZLD Plant

One of the commonly used industrial ZLD configurations is:

ETP → RO → MEE → ATFD

In this configuration:

• ETP treats the industrial effluent.

• RO recovers a major portion of the water.

• MEE concentrates the RO reject.

• ATFD handles the final concentrated stream.

The final residue can be converted into dry or semi-dry solids depending on the wastewater chemistry and equipment design.

RO + MVR ZLD Plant

Mechanical Vapor Recompression (MVR) can be incorporated into evaporation systems where energy optimization is an important consideration.

MVR compresses generated vapor and reuses its heat within the evaporation process.

A suitable MVR-based ZLD system can help optimize thermal energy consumption, although the final technology selection depends on wastewater characteristics, electricity availability, operating conditions and project economics.

ZLD Plant with Crystallizer

A crystallizer can be used when concentrated wastewater needs to be converted into solid crystals.

A typical process is:

ETP → RO → Evaporator → Crystallizer → Solid Salt

The actual composition of the recovered solids depends on the wastewater chemistry. Laboratory testing is recommended before considering salt recovery or commercial reuse.

V Aqua ZLD solutions can be configured using several advanced wastewater treatment technologies, including:

• Effluent Treatment Plant – ETP

• Sewage Treatment Plant – STP

• Common Effluent Treatment Plant – CETP

• Ultrafiltration – UF
