Paper & Pulp

High-Volume, High-Load—Solved Naturally with DeurRR

The Problem: Fiber-Rich, Chemically Complex Effluents

The paper & pulp industry generates vast quantities of wastewater during pulping, bleaching, and paper-making stages. This effluent is loaded with lignin, suspended solids, colorants, and toxic organochlorines—making it difficult to treat, reuse, or discharge safely.

Ph
4.5–10.5, disrupts biological treatment
Sludge Volume
High, cellulose-heavy and hard to handle
Color (Lignin Compounds)
High, persistent hue, hard to treat
Total Suspended Solids (TSS)
1000–6000 mg/L, fibers clog filters
Chlorinated Organics (AOX)
0.5–10 mg/L, toxic and regulated
Chemical Oxygen Demand (COD)
2000–70000 mg/L, lignin drives load
Biological Oxygen Demand (BOD₅)
500–30000 mg/L, overloads aerobic systems
Foam, Odor
Moderate–High, microbial and resin-induced

DeurRR Advantage: Clean Fiber, Clean Future

⚠️ Conventional:
– Polymer dosing + filtration

✅ With Deur:
– Herbal coagulation + nanobubble flotation—low-sludge clarity

⚠️ Conventional:
– Oxidation + adsorbents

✅ With Deur:
– Advanced oxidation of lignin + color collapse through OH• radicals

⚠️ Conventional:
– Aerobic/anaerobic + polishing

✅ With Deur:
– Rapid organics breakdown, no biotoxicity, minimal footprint

⚠️ Conventional:
– Activated carbon + chemical oxidation

✅ With Deur:
– Reduces AOX without secondary toxicity

⚠️ Conventional:
– Requires pH conditioning

✅ With Deur:
– Operates across broad pH without additional chemicals

⚠️ Conventional:
– Defoamers and pH buffering

✅ With Deur:
– Suppressed naturally via oxidation and plant-based additives

⚠️ Conventional:
– High volume and cost

✅ With Deur:
– 30–60% less sludge, easier to manage, non-toxic

Impact Snapshot

  • COD/BOD Reduction: 60–80% (COD up to 70,000 mg/L)

  • Color Removal: Up to 80% (lignin and brown tint)

  • AOX Reduction: Effective breakdown of toxic chlorinated compounds

  • Sludge Volume: 30–60% reduction with improved dewaterability

  • Output Water: Clear, odor-free, ready for reuse or safe discharge

DeurRR: A Circular Step for a Sustainable Paper Industry

DeurRR enables pulp & paper units to meet ZLD, reuse, and compliance goals—without heavy chemical loads or complex infrastructure. Treat fiber-rich effluent cleanly, and keep your operations circular, green, and future-ready.
