Zero Liquid Discharge (ZLD) Turnkey Solutions
From initial layout design to final commissioning. We build intelligent, closed-loop wastewater recycling plants that guarantee 100% environmental compliance and maximum water reuse.
How We Build Your System
We take the guesswork out of wastewater management. Our step-by-step approach ensures a perfectly tailored system for your production line.
Site Analysis & Design
We analyze your wastewater volume, chemical composition, and factory footprint to draft precise P&ID diagrams and 3D CAD layouts.
In-House Manufacturing
Every settling tower, filter press, and dosing unit is manufactured in our ISO-certified facility to ensure seamless integration and quality control.
PLC System Integration
We wire all components into a central Siemens PLC control cabinet, creating a smart, automated loop that requires minimal human intervention.
Global Commissioning
Our expert engineers travel to your site to oversee installation, perform wet runs, and thoroughly train your maintenance team.

A Perfect Closed-Loop Ecosystem
Buying individual machines often leads to pressure mismatches, pipe blockages, and inefficient chemical dosing.
With a PORVOO Turnkey Plant, every valve, pump, and sensor is calibrated to “talk” to each other. When the Wastewater Tower is full, the Auto-Dosing Unit injects chemicals. When the sludge thickens, the Ceramic Plunger Pump automatically feeds the Filter Press. It’s harmony in engineering.
✅ The ZLD Guarantee:
- Recycle up to 95% of your process water.
- Achieve ultra-dry solid waste for cheap disposal.
- Eliminate environmental fines entirely.
