- Colour removal from dyes and lignin.
- Closure of water loops driving higher dissolved solids.
Our Solutions
- Whitewater treatment: Dissolved air flotation for fibre and filler recovery (achieving >90% solids removal); recovered fibre returned to stock.

- Colour removal: Coagulation-flocculation with ferric or aluminium salts; advanced oxidation for persistent colour.
- Water loop closure: Filtration and treatment of broke and save-all water.
Textile Manufacturing
Colour, BOD and heavy-metal removal for dyehouse and finishing effluent treated to ZDHC guidelines and local colour-discharge limits.

Corrosion-resistant, ATEX-compliant treatment for variable, aggressive process wastewater from batch and continuous campaigns.
Key Challenges
- Wastewater containing acids, alkalis, solvents, and reaction byproducts.
- High variability due to batch campaigns.
- Corrosive environments requiring specialised materials.
- ATEX requirements for volatile organic compound (VOC) handling.
Our Solutions
