Zero Liquid Discharge (ZLD) Unit Manufacturer in Gujarat

Introduction

A Zero Liquid Discharge (ZLD) Unit integrates physical-chemical, membrane, and thermal stages to recover reusable water and convert the final brine into dry salts—eliminating liquid effluent release. Siddhi Vinayak Engineering designs right-sized ZLD units for Indian industries facing strict norms and water scarcity, with modular skids, robust metallurgy, and automation-first controls.

Description

The ZLD unit starts with equalization and chemical conditioning, followed by media filtration and UF/RO for high-permeate recovery. Concentrates are routed to energy-efficient MEE/MVR evaporators, and a crystallizer + ATFD/centrifuge converts remaining brine to dry solids. Polished condensate is reused for utilities or process make-up, closing the loop and stabilizing the plant water balance.

Applications and Benefits

Applications	Benefits
Textile & dyeing clusters with saline, color-rich effluents Pharma/API & specialty chemicals with multi-stream high TDS Food & dairy CIP streams requiring reuse and compliance Power & metals: cooling tower/boiler blowdown, mine water Industrial estates seeking centralized ZLD solutions	Compliance with near-zero discharge requirements High water recovery to reduce freshwater dependency Lower environmental risk via safe solid-salt handling Optimized steam/power use with MEE/MVR integration PLC-HMI control with alarms, data logging, and remote support

Key Features of the ZLD Unit

Tailored pre-treatment: neutralization, coagulation–flocculation, oil/grease removal
High-recovery membranes with anti-scalant dosing and clean-in-place (CIP)
MEE/MVR stages with vapour–liquid separation and condensate recycle
Crystallizer with controlled nucleation; ATFD/centrifuge for dry solids
Durable metallurgy (SS316/duplex) for chloride- and TDS-rich duty
Safety interlocks, emergency shutdowns, and brine storage safeguards
Modular skids enabling phased capacity expansion
Energy & water balance dashboards on PLC-HMI

Where ZLD Units Are Used

Pharma & Chemicals: Segregated mother liquors and RO rejects
Textile & Dyeing: High salt/color loads with reuse needs
Food & Beverages: CIP and wash waters with reuse potential
Utilities & Mining: Blowdown, leachate, and pit water recovery

Why Choose Us?

Siddhi Vinayak Engineering provides end-to-end execution—mass balance, P&IDs, fabrication, erection, commissioning, trials, and AMCs. Our focus is membrane life, steam economy, and reliable salt handling for consistent uptime and predictable OPEX in Indian conditions.

Uses & Importance

ZLD units convert wastewater liabilities into reusable resources. By maximizing permeate recovery and responsibly managing residues, plants ensure regulatory compliance, protect groundwater, and secure long-term water availability for uninterrupted production.

FAQs

1. What recovery can I expect from a ZLD Unit?

Recovery depends on feed chemistry; membranes maximize reuse first, with thermal stages treating the final brine to solids.

2. Is MVR always better than MEE?

MVR can offer lower steam use but needs stable power and specific capacities. We evaluate LCC (lifecycle cost) before selection.

3. How are salts handled and stored?

Crystallized salts are centrifuged/ATFD-dried and stored per norms. We design handling and storage as part of the scope.

4. Can the unit be expanded later?

Yes. Modular skids and staged evaporation allow phased capacity increases as flows grow.

5. What about energy consumption?

Energy is optimized via high-recovery membranes, heat integration, and MEE/MVR selection based on detailed mass–energy balance.

Conclusion

Choose Siddhi Vinayak Engineering for engineered Zero Liquid Discharge Units that unite high recovery, stable operation, and assured compliance—purpose-built for Gujarat and pan-India deployment.
