Ankleshwar is one of Asia's largest chemical industrial estates, home to thousands of chemical, pharma, agrochemical and dye units in Ankleshwar, Panoli and Jhagadia GIDC. Industries producing high-TDS and hazardous effluent are increasingly expected to recycle all their wastewater rather than discharge it.
We serve clients across:
Zero Liquid Discharge (ZLD) is a wastewater management approach in which all effluent is treated and recycled, with dissolved salts recovered as solids, so that no liquid waste leaves the plant. Explore our complete range of Zero Liquid Discharge (ZLD).
| Technology | Role in ZLD | Benefit |
|---|---|---|
| Pre-Treatment & ETP | Removes suspended solids, organics and hardness | Protects downstream membranes and evaporators |
| Reverse Osmosis (RO) | Recovers the bulk of water as permeate | Reduces evaporator size and energy |
| Advanced Oxidation (AOP) | Breaks down hard-to-treat organic pollutants | Improves recovery and reject quality |
| Multiple Effect Evaporator (MEE) | Concentrates RO reject | Recovers additional water as condensate |
| Crystallizer / ATFD | Converts concentrate into dry solids | Truly zero liquid discharge |
Multi-stage RO for maximum recovery before thermal treatment.
Evaporators and crystallizers to convert concentrate to solids.
Optimised mix of membrane and thermal stages for lowest operating cost.
Site survey, load study and plant design tailored to your requirement.
Manufacturing, delivery, erection and commissioning of the complete plant.
Trained operators and preventive upkeep through our O&M services.
Treated-water testing and documentation via our environmental monitoring team.
Yes. Portico Environmental Services designs, supplies, installs and commissions Zero Liquid Discharge plants for industries in Ankleshwar, serving Ankleshwar GIDC, Panoli GIDC, Jhagadia GIDC and nearby areas.
ZLD requirements depend on your industry category, effluent characteristics and the conditions set by the Gujarat Pollution Control Board (GPCB) and CPCB. We review your consent conditions and effluent profile and recommend the right approach.
A typical ZLD plant combines effluent treatment, softening, multi-stage RO, multiple effect evaporators and a crystallizer or dryer. The exact combination depends on your effluent.
Maximising RO recovery before thermal stages, good pre-treatment and heat integration significantly reduce evaporator load and running cost. We design hybrid systems with this in mind.
Yes. We offer ZLD operation and maintenance with trained operators, chemical supply and performance reporting.
