High-Strength Effluent, Natural Remediation with DeurRR

The Problem: Spent Wash Overload & Organic Shock

Distilleries produce massive volumes of high-COD, high-BOD wastewater—mainly from molasses spent wash—that is dark, odorous, and extremely difficult to treat. Conventional biological systems are often overwhelmed by the load, leading to odor, compliance failures, and environmental risks.

Ph
4.0–5.5, acidic and corrosive
Sludge Volume
Very high, odorous and hard to stabilize
Color (Melanoidin)
Deep brown–black, persistent and hard to treat
Total Suspended Solids (TSS)
3000–10000 mg/L, turbidity and sludge handling
Odor & Foaming
Severe, public and biological instability
Chemical Oxygen Demand (COD)
30k–250k mg/L, sugars and protein load
Biological Oxygen Demand (BOD₅)
15k–100k mg/L, anaerobic failure, odor issues
Sulphates & Sulphides
200–2000 mg/L, corrosion and foul H₂S gas

DeurRR Breakthrough: Spent Wash Meets Sustainable Science

⚠️ Conventional:
– Anaerobic lagoons + polishing ponds

✅ With Deur:
– Rapid breakdown of organics using OH• radicals and ozone (ioniX)

⚠️ Conventional:
– Advanced oxidation, RO

✅ With Deur:
– Natural oxidative degradation and pigment collapse

⚠️ Conventional:
– Coagulation with lime/alum

✅ With Deur:
– Low-sludge herbal coagulation with HerbX + nanobubble flotation

⚠️ Conventional:
– pH correction with alkalis

✅ With Deur:
– Operates effectively at low pH without adjustment

⚠️ Conventional:
– Lime + deodorants

✅ With Deur:
– Immediate odor suppression via oxidation & herbal stabilization

⚠️ Conventional:
– High volume, septic sludge

✅ With Deur:
– 30–60% less sludge; non-toxic and compostable

Impact Snapshot

  • COD/BOD Reduction: 60–80% (COD up to 180,000 mg/L; BOD up to 40,000 mg/L)

  • Color Removal: Up to 75% (melanoidin and pigments)

  • Odor & Foaming: Controlled within minutes

  • Sludge Volume: Reduced by up to 60%, less toxic

  • Output Water: Clearer, safer for reuse in non-potable processes

Ferment Clean with DeurRR

DeurRR empowers distilleries to meet stringent norms while drastically lowering sludge, odor, and treatment time. Whether for molasses, grain, or fruit-based units—our nature-driven, plug-and-play system keeps your operations clean, compliant, and circular.
