Textile Industry Wastewater Treatment
Textile Industry Wastewater Treatment
Nanozyme bioculture support for textile wet-processing ETPs
Bionics Nanozyme bioculture supports textile industry wastewater treatment where sizing, desizing, scouring, bleaching, washing and finishing create variable organic and chemical loads.
Industry overview
Textile Industry
Textile wet processing generates wastewater from sizing and desizing, scouring, bleaching, mercerising, washing, printing and finishing. The composition changes with fibre type, recipe, production schedule and chemical use.
Starches, sizing agents, fibres, surfactants, oils, waxes and finishing chemicals contribute variable COD, BOD, TSS, foam and pH. Dye-intensive streams are addressed separately because colour, salts and recalcitrant dye molecules require a different treatment strategy.
Bionics Nanozyme bioculture supports compatible biodegradable loads in the assessed biological stage after segregation, equalisation and required pretreatment. Product selection depends on wastewater analysis, salinity, toxicity, dissolved oxygen and biomass condition.
Wastewater Characteristics
Textile Industry Wastewater Characteristics
Textile Industry wastewater varies with raw materials, production schedules and cleaning operations. Assessment is required before biological application.
| Parameter | Typical Range |
|---|---|
| COD and BOD | Variable with sizing, desizing, scouring, washing and finishing operations |
| Sizing Agents and Starch | Biodegradable organic load where compatible |
| TSS and Fibre | Lint, fibre fragments and suspended process solids |
| Surfactants and Oils | Can cause foam and affect oxygen transfer |
| pH | Variable with alkaline and acidic wet processes |
| Temperature | Can be elevated in hot process and wash streams |
| TDS / Conductivity | Process dependent and relevant to biomass tolerance |
| Flow and Batch Load | Changes with recipes, shifts and washing cycles |
Major Pollutants
Common Contaminants in Industrial Streams
The biological treatment approach targets the main pollutants that influence process reliability and discharge quality.
Sizing Agents and Starch
Desizing streams can create strong biodegradable COD and BOD loads.
Fibre and Suspended Solids
Lint and fibre fragments require screening and solids removal.
Surfactants, Oils and Waxes
Scouring and finishing residues may cause foam and inhibit oxygen transfer.
Wet-Process Chemicals
Bleaching, mercerising and finishing streams require pH and toxicity assessment.
Industry Challenges
Textile Industry Wastewater Treatment Challenges
Textile ETP performance depends on wet-process segregation, fibre recovery, pH and temperature control, equalisation and stable aeration.
Variable Process Loads
Different fabrics and recipes change flow and organic loading.
pH and Temperature Shock
Hot alkaline or acidic streams can destabilise biomass.
Foaming
Surfactants and finishing agents can interfere with aeration and clarification.
Fibre Carryover
Poor screening increases TSS and sludge-handling demand.
Low Oxygen Transfer
High organic loads and surfactants can reduce effective aeration.
Seasonal or Recipe Variation
Changing production requires monitoring and controlled biological response.

Biological Treatment Mechanism
Stepwise Biological Conversion
Nanozyme supports the biological process from hydrolysis through mineralization.
Textile-Stream Assessment
Wet processes, organic load, pH, salinity, surfactants and biomass are reviewed.
Culture Preparation
The selected BET-ETP grade is activated through the approved procedure.
Controlled Application
Prepared culture is introduced into the assessed aerobic biological stage.
Biological Conversion
Living cultures support hydrolysis and oxidation of compatible textile organics.
Operating Review
DO, pH, loading, foam, settling and outlet trends guide application.
Scientific Reaction Section
Useful Engineering Reactions
Concise reaction pathways that support practical treatment understanding and plant engineering decisions.
Sizing-Agent Hydrolysis
Complex starch and sizing organics → soluble biodegradable compounds
Enzymatic hydrolysis supports subsequent microbial uptake where the stream is compatible.
Aerobic Organic-Matter Conversion
Biodegradable textile organics + O₂ → CO₂ + H₂O + biomass
A simplified representation of aerobic conversion under controlled ETP conditions.
Why Nanozyme
Bionics Bioculture Solutions for Textile Industry Wastewater Treatment
