Industrial wastewater treatment faces unprecedented challenges today. From tightening environmental regulations to soaring energy costs, industries urgently need solutions that balance efficiency, sustainability, and cost-effectiveness. Enter NTSALT's Disc Technology – a groundbreaking approach redefining evaporation efficiency for high-salt, high-COD, and toxic wastewater streams.
Traditional evaporators, like tank-based systems, struggle with three critical flaws:
High energy consumption (heating entire wastewater volumes).
Inefficiency with complex waste (e.g., scaling in high-salt streams).
Massive footprints (limiting plant flexibility).
NTSALT's disc technology addresses these pain points head-on, offering a compact, energy-smart alternative that handles even the toughest industrial effluents – from copper sulfate-laden mining wastewater to pharmaceutical COD-heavy residues.
Corrosion-resistant materials: 316L stainless steel, SAF2507 duplex steel, or titanium alloys withstand aggressive chemicals (e.g., sulfuric acid in copper sulfate treatment).
Thin-film evaporation: Wastewater spreads into a micron-thin layer on rotating heated discs, vaporizing 20% faster than tank-based bulk heating.
Automatically removes dried solids with ≤8% moisture – a stark improvement over the 15–20% residue from centrifuges or filter presses.
Self-cleaning discs prevent scaling, a common issue in high-TDS wastewater.
Recovered vapor condenses into 99% COD-free distillate, reusable in processes or safe for discharge.
Heat exchangers recycle thermal energy, minimizing steam demand.
Feeding: Wastewater is pumped onto rotating discs heated internally by steam or thermal oil.
Instant Evaporation: The disc's high surface area vaporize water in seconds.
Solid Recovery: A blade scrapes bone-dry solids (e.g., copper sulfate crystals) into a collection hopper.
Distillate Harvesting: Pure water vapor condenses for reuse, while non-condensables are extracted.
Challenge: Acidic wastewater with heavy metals (e.g., copper sulfate from leaching).
Solution: Disc dryers recover >98% of copper as dry solids (≤8% moisture), while distillate meets discharge standards.
Challenge: High-salinity brine (100,000+ ppm TDS) and organic solvents.
Solution: Thin-film evaporation prevents fouling, even with viscous or crystallizing streams.
Challenge: Wastewater containing hazardous metals such as chromium, nickel, or zinc.
Solution: SAF2507 or titanium discs provide excellent corrosion resistance, enabling the conversion of metal-laden residues into stable, disposable solids.
Challenge: Antibiotic fermentation broth with COD >50,000 mg/L.
Solution: Low-temperature operation preserves heat-sensitive organics while achieving 99% COD removal.
Challenge: High-color, high-ammonia wastewater.
Solution: Distillate clarity <10 NTU, enabling direct reuse in dye baths.
| Factor | NTSALT Disc Dryer | Tank Evaporator |
|---|---|---|
| Energy Efficiency | 35% higher thermal efficiency | High steam consumption |
| Footprint | 50% smaller | Bulky tanks require more space |
| Moisture in Residue | ≤8% | 15–20% |
| Maintenance | Self-cleaning discs; low scaling | Frequent descaling needed |
A: Yes. The thin-film design prevents salt buildup, making it ideal for hypersaline brine from RO reject or mining operations.
A: Most users achieve payback in 2–3 years via
A: Yes. PLC controls adjust disc speed, temperature, and scraper pressure for hands-off operation.
NTSALT's technology is a cornerstone for circular wastewater management:
Dry solids: Landfill-safe or recyclable (e.g., copper recovery).
Reusable water: Distillate meets boiler feed or process standards.
Carbon footprint: 50% lower CO₂ emissions vs. incineration or tank evaporation.
For industries battling complex wastewater, NTSALT's disc technology isn't just an upgrade – it's a paradigm shift. With unmatched efficiency, compact design, and versatility across waste streams, it's redefining what's possible in sustainable wastewater treatment.
