Tobacco WWTP covers leaf processing, cigarette manufacturing and tobacco extract plants. Volume is moderate (50-500 m³/day) but nicotine toxicity demands specialized treatment.
Tobacco effluent: COD 2,000-8,000 mg/L, BOD 800-3,000 mg/L, nicotine 50-500 mg/L, dense polyphenols and chlorogenic acid. Color 3,000-10,000 Pt-Co.
Arsistek tobacco solutions combine equalization, coagulation, GAC adsorption and adapted biological treatment. Nicotine-tolerant biomass adaptation is critical.
Tobacco Effluent Characterization
Tobacco production has 3 main streams: leaf washing (dust, soil, pesticides), fermentation/casing (organic acids, sugars), extract production (high nicotine, polyphenols).
Extract stream is hardest — nicotine 500+ mg/L is toxic to bacteria. Without adapted biomass standard activated sludge fails.
Color comes from natural pigments (chlorophyll derivatives, polyphenols). Coagulation removes 60-70%; GAC polishing follows.
Activated Carbon Adsorption
GAC serves two purposes: nicotine capture and color removal.
GAC column with 15-30 min EBCT retains 95%+ nicotine. Regeneration cycle 6-12 months. Saturated carbon is thermally regenerated or disposed.
Adapted Biomass
Customized activated sludge with nicotine-tolerant Pseudomonas strain. Adaptation takes 8-12 weeks.
Adapted biomass metabolizes 100-200 mg/L nicotine. MLSS maintained 4,000-6,000 mg/L.
Full Process Flow
Tobacco WWTP in 6 stages:
- Screening + equalization
- Coagulation-flocculation: PAC/Fe2(SO4)3
- Primary clarifier or DAF
- Biological: Adapted activated sludge or MBR (SRT 10-15 d)
- GAC polishing
- Disinfection: Chlorine or UV
Total HRT 24-36 h. COD removal 95%+, color 90%+.

Frequently Asked Questions
Nicotine above 50 mg/L is toxic to standard activated sludge — die-off and sulfite formation. Adapted Pseudomonas tolerates 100-200 mg/L.
6-12 months in tobacco effluent. Monitored for color/nicotine breakthrough; regenerated at 5-10% breakthrough — thermal regen or replacement.
Cellulose acetate filter fibers may appear. Trapped at pre-screening to prevent biological stage interference.
Leaf wash effluent contains OP and carbamate residues. GAC adsorbs these. High loads need Fenton pre-oxidation.
Yes — pure culture seeding or pre-adapted seed sludge cuts the 8-12 weeks to 3-4 weeks.
Suitable for landscape irrigation, plant washdown or cooling tower makeup. With UF+RO reuse module, can reach potable quality.
