Zero Liquid Discharge (ZLD) Turnkey Plants
From initial 3D layout design to final installation and commissioning. We deliver fully automated, closed-loop water recycling systems that guarantee 100% environmental compliance.
One Contractor. One Perfect Ecosystem.
Sourcing equipment from multiple vendors leads to bottlenecked pipelines, software conflicts, and finger-pointing when things go wrong. PORVOO takes full responsibility for your entire wastewater treatment plant.
Custom Plant Engineering
We don’t offer generic setups. Our engineering team calculates your peak flow rates, sludge concentration, and factory footprint to draft a bespoke 3D piping and equipment layout.
Flawless Integration
Because we manufacture the silos, pumps, and filter presses in-house, we guarantee perfect hydraulic synergy. The pump capacity will flawlessly match the press volume without overloading.
Centralized Master Control
The entire plant is wired into a single master PLC cabinet. A user-friendly touchscreen allows your operator to monitor tank levels, pump pressures, and dosing ratios in real-time.
The 4-Step Closed-Loop Process
Collection & Smart Dosing
Dirty factory water flows into the collection pit. The PORVOO Auto Dosing System injects the exact ratio of PAM/PAC flocculant to instantly bind floating particles together.
Clarification (Clean Water Return)
The treated water is pumped into the Deep Cone Silo. Heavy sludge sinks to the bottom, while 100% clean water overflows at the top, returning directly to your cutting machines.
High-Pressure Pumping
The thick sludge at the bottom of the silo is sucked up by the ultra-durable Hydraulic Ceramic Plunger Pump, which blasts the mud into the filter press at up to 20 Bar of pressure.
Final Dewatering & Cake Drop
The Automatic Filter Press squeezes out the remaining moisture. The automated plate shifter opens, dropping dry, solid mud cakes ready for easy, low-cost disposal.
Worldwide Installation & Commissioning
Expertly packed in flat racks and open-top containers for safe ocean freight.
Our technicians travel to your factory to supervise piping and electrical wiring.
We don’t leave until your team knows exactly how to run and maintain the plant.
