Zero liquid discharge system

Zero liquid discharge system

Zero Liquid Discharge (ZLD) System Manufacturer in Gujarat

Zero Liquid Discharge (ZLD) System Manufacturer in Gujarat


Introduction

Need a dependable Zero Liquid Discharge (ZLD) system that recovers water, salts, and heat—while meeting CPCB/GPCB norms? Siddhi Vinayak Engineering designs integrated ZLD solutions combining membrane and thermal units to convert complex effluents into reusable condensate and solid crystals, minimizing fresh-water intake and eliminating liquid discharge.


Description

A ZLD system typically couples primary ETP/biological treatment with RO/UF for recovery, followed by Multi-Effect Evaporator (MEE), MVR/TVR, and ATFD/Crystallizer for final concentration and salt recovery. Our PLC-HMI packages provide recipe control, energy balance monitoring, and interlocks for safe operation. Skid-mounted modules, corrosion-resistant metallurgy, and clean-in-place friendly layouts ensure reliable performance on high-TDS, high-COD streams from diverse industries.


Applications and Benefits

Applications Benefits
  • Pharma & chemicals: solvent-laden, high-TDS process effluents
  • Textiles & dyes: color, TDS, and hardness removal with salt recovery
  • Food & beverage: CIP streams, condensate polishing, reuse
  • Metals & surface treatment: rinse water recycle, sludge minimization
  • Landlocked plants targeting zero discharge & water circularity
  • 100% liquid discharge elimination; compliance with local norms
  • High water recovery to reduce freshwater demand and OPEX
  • Salt/crystal recovery with options for by-product value
  • Compact modular skids with quick installation and scale-up
  • Energy-optimized MEE/MVR integration and heat recovery

Key Features of ZLD Systems

  • Integrated train: ETP/DAF → UF/RO → MEE/TVR/MVR → ATFD/Crystallizer
  • PLC-HMI with trend logging, alarms, and interlocks for safe operation
  • Material options: SS316/316L, duplex, special alloys for chloride resistance
  • Optimized steam economy via multiple effects and condensate reuse
  • HEPA-ready panels and enclosed layouts to reduce aerosol carryover
  • WIP/CIP-friendly design for faster turnaround and consistent hygiene
  • Redundancy on critical pumps, instruments, and utilities
  • Condensate Polishing Unit (CPU) for reuse in boiler/cooling make-up

Where ZLD Systems Are Used

  • Pharmaceuticals & Specialty Chemicals: High-TDS, multi-component streams with solvent traces
  • Textiles, Dyes & Intermediates: Color/TDS removal with salt recovery and recycle
  • Food & Beverages: Reclaiming CIP and process water; condensate polishing

Why Choose Us?

With 12+ years and 250+ installations, Siddhi Vinayak Engineering delivers robust, energy-efficient ZLD plants. We provide pilot trials, mass-balance studies, P&IDs, FAT/SAT, and lifecycle service—so you can achieve compliance, reduce water risk, and meet ESG goals confidently.


Uses & Importance

ZLD converts wastewater liabilities into assets by maximizing reuse and crystallizing solids for safe handling. It safeguards groundwater, supports green compliance, and stabilizes operations against water scarcity—improving sustainability metrics and long-term operating costs.


Manufacturer & Supplier Information

Siddhi Vinayak Engineering, Ahmedabad, is a manufacturer, exporter, and supplier of ZLD Systems, Multi-Effect Evaporators, ATFD/Crystallizers, Flash Dryers, Fluid Bed Dryers, Evaporators, Hot Air Generators, and allied process equipment.

FAQs

1. What influent flow and TDS ranges can you handle?
Systems are engineered case-by-case based on flow, COD/BOD, and TDS. We size RO/MEE/ATFD stages to achieve target recovery and solids handling.
2. Which technologies go into a typical ZLD train?
Pretreatment (clarifier/DAF/biological), membranes (UF/RO), thermal concentration (MEE with TVR/MVR), and final solids via ATFD/Crystallizer plus CPU for reuse.
3. How do you minimize energy consumption?
We optimize effects, vapor recompression, condensate heat recovery, and integrate waste heat where feasible—backed by energy balance calculations.
4. What space/utilities are required?
Modular skids reduce footprint. We share a detailed utility matrix (power, steam, cooling, air) and GA/foundation drawings during engineering.
5. Do you provide documentation for compliance?
Yes—FAT/SAT, IQ/OQ support, operating SOPs, and logs to demonstrate CPCB/GPCB compliance and audit readiness.

Conclusion

Choose Siddhi Vinayak Engineering for reliable ZLD systems that deliver high recovery, low energy per m³, and assured compliance—so your plant operates sustainably with true zero liquid discharge.
