Roadmap Towards Zero Liquid
Roadmap Towards Zero Liquid
With increasing water scarcity and strict environmental regulations, industries are moving towards Zero Liquid Discharge (ZLD) to eliminate wastewater disposal and maximize water reuse. Purlieusinc offers a structured and practical Roadmap Towards Zero Liquid Discharge, helping industries transition step-by-step to sustainable, compliant, and cost-effective water management.
Our roadmap is designed to reduce freshwater consumption, minimize effluent discharge, and achieve 100% wastewater recovery without disrupting operations.
What Is a Roadmap Towards Zero Liquid Discharge?
A ZLD Roadmap is a phased, data-driven approach that evaluates existing water usage, identifies gaps, and implements optimized treatment technologies to achieve zero liquid discharge in a systematic manner.
Purlieusinc’s roadmap focuses on:
Water conservation
Wastewater minimization
Maximum reuse and recycling
Regulatory compliance
Our Step-by-Step ZLD Roadmap
1. Water & Wastewater Audit
We conduct a detailed water balance study to analyze:
Raw water consumption
Process water usage
Effluent generation points
Losses and reuse potential
This audit forms the foundation for an effective ZLD strategy.

2. Effluent Segregation & Load Reduction
Different effluent streams are segregated based on quality and load. Our team identifies opportunities to:
Reduce BOD, COD, TDS at source
Optimize cleaning and process water usage
Improve operational efficiency
3. Process Optimization & Minimization
Before adding new systems, Purlieusinc focuses on:
Process modifications to reduce wastewater generation
Reuse of low-contaminated streams
Reduction of chemical and energy consumption
4. Primary & Secondary Treatment (ETP / STP)
We design or upgrade ETP and STP systems to ensure:
Stable biological performance
Effective removal of organic and suspended solids
Treated water suitable for tertiary treatment
5. Advanced Tertiary Treatment (RO, UF, MBR)
High-quality treated water is recovered using advanced systems such as:
Reverse Osmosis (RO)
Ultra-Filtration (UF)
Membrane Bioreactor (MBR)
Recovered water is reused for process, utility, and cooling applications.
6. Concentrate & Reject Management (MEE / ATFD)
RO reject is treated using:
Multi Effect Evaporator (MEE)
Agitated Thin Film Dryer (ATFD)
This step ensures complete elimination of liquid discharge.
7. Water Reuse & Integration
Recovered water is integrated back into:
Process operations
Boiler feed (with EDI/RO polishing)
Cooling towers
Utility applications
This significantly reduces freshwater dependency.
8. Automation, Monitoring & Compliance
Purlieusinc implements:
Online monitoring systems
Automation for stable operation
Compliance reporting as per CPCB/SPCB norms
