Zero Liquid Discharge (ZLD) System Project

Introduction

Planning a Zero Liquid Discharge (ZLD) system project to meet strict discharge norms and recover maximum water? Siddhi Vinayak Engineering designs end-to-end ZLD plants that integrate primary treatment, membrane systems, multiple-effect evaporation, and crystallization to achieve near-100% wastewater recovery with safe solid disposal.

Description

A ZLD system eliminates liquid effluents by concentrating and crystallizing dissolved solids from industrial wastewater. Typical trains combine equalization + clarification, advanced filtration (UF/RO), MEE/MVR evaporators, ATFD/Crystallizer, and condensate polishing. Our engineered projects optimize energy, scaling control, and salt management—delivering stable operation, high recovery, and compliance across variable feed chemistries.

Applications and Benefits

Applications	Benefits
Chemical & dyes, textiles, pharma & bulk drugs, food & beverages Coal/steel power utilities, desalination brine, landfill leachate High TDS/TOC streams, mixed effluents, complex inorganics/organics Retrofits to ETP/STP for zero discharge mandates Resource recovery: water reuse, mother liquor reprocessing, salt valorization	Regulatory compliance with near-zero liquid discharge at battery limits Up to 90–97% water recovery with stable permeate quality Lower operating cost via energy integration, MVR, and condensate reuse Robust anti-scalant, CIP, and materials selection for uptime Modular design enabling phased capacity expansion

Key Features of a ZLD Project

Front-end characterization, treatability studies, and pilot runs
Skid-based UF/RO with high-recovery brine concentrator design
MEE/MVR evaporators with steam economy & fouling-resistant internals
ATFD/centrifuge/crystallizer for salt recovery and cake dryness
Condensate polishing unit (CPU) for reusable process water
PLC-HMI/SCADA with recipe, historian, alarms & remote diagnostics
CIP/WIP loops, scale control, and anti-foam dosing strategies
Corrosion-resistant metallurgy (SS, duplex, alloys) and FRP tanks

Where ZLD Systems Are Used

Textile & Dyeing: Color laden, high-TDS streams with salt recovery
Pharmaceuticals & Chemicals: Complex organics, solvent traces, APIs
Power & Metals: Cooling tower blowdown, ash pond leachate, pickling

Why Choose Us?

With 12+ years and 250+ process installations, Siddhi Vinayak Engineering delivers concept-to-commissioning ZLD projects—basic & detailed engineering, fabrication, automation, erection, FAT/SAT, operator training, and lifecycle support.

Uses & Importance

ZLD enables water positivity, reduces freshwater intake, and turns compliance into value by reusing condensate and monetizing salts where feasible. It safeguards groundwater, meets CPCB/PCB norms, and de-risks expansions in water-stressed regions.

Manufacturer & EPC Information

Siddhi Vinayak Engineering, Ahmedabad, executes turnkey ZLD System Projects—from pilot validation to full-scale UF/RO, MEE/MVR, ATFD, crystallization, and condensate reuse lines—customized to feed matrix, utilities, and footprint.

FAQs

1. What data do you need to size a ZLD plant?

Feed flow & variability, TDS/COD/TOC/SS, scaling indices, solvent content, and available utilities (steam, power, cooling, air) determine the scheme and capacities.

2. Can ZLD handle high organics or solvents?

Pre-oxidation/stripping, biological or advanced oxidation, and staged RO/evaporation are applied to manage organics and improve thermal load distribution.

3. How is salt managed?

Crystallizer/ATFD yields solid salt for secure landfill or recovery. Mother liquor is recycled where viable. We evaluate valorization options case-by-case.

4. What about energy consumption?

We maximize RO recovery, deploy MVR/TVR, recover condensate heat, and integrate pinch analysis to reduce specific energy while maintaining reliability.

5. Do you provide piloting and operator training?

Yes—on-site/pilot trials, SOPs, and training ensure smooth start-up, stable KPIs, and safe operations.

Conclusion

Choose Siddhi Vinayak Engineering for reliable ZLD System Projects—engineered for compliance, high recovery, and optimized lifecycle cost.
