Advanced Sludge Drying & Water Recycling Solutions
At Porvoo, we believe true environmental engineering doesn’t stop at basic compliance. We help modern industries achieve ultimate cost savings and sustainability through drastic waste volume reduction and process water recovery.
1. Low-Temperature Sludge Dryers (Heat Pump Technology)
A conventional filter press will reduce sludge moisture to around 60-80%. Our Low-Temperature Heat Pump Dryers take over from there, evaporating the remaining water to produce dry, granular solids with only 10% to 30% moisture content.
- Massive Cost Reduction: Decreases the final weight and volume of hazardous or municipal sludge by an additional 60-80%, drastically cutting transportation and landfill fees.
- Eco-Friendly & Odorless: Operates in a fully closed loop at low temperatures (40°C – 75°C). No heat loss to the environment and zero foul odor emissions.
- High ROI: For industries dealing with expensive hazardous waste disposal (e.g., electroplating, chemical processing), the machine pays for itself in less than a year.
2. Industrial Water Recycling & ZLD Systems
Freshwater is becoming a premium resource. Porvoo designs scalable membrane systems that treat your factory’s effluent so it can be reused in your cooling towers, boilers, or production lines.
| Technology | Application & Benefit |
|---|---|
| Ultrafiltration (UF) Systems | Removes suspended solids, bacteria, and macromolecules. Excellent pre-treatment for RO systems or for non-potable factory washing. |
| Reverse Osmosis (RO) Systems | Removes dissolved salts and heavy metals, providing ultra-pure water that often exceeds municipal water quality standards. |
| MVR Evaporators (ZLD) | For Zero Liquid Discharge. Evaporates the highly concentrated brine from RO reject water, leaving only solid salt crystals. |
