An export oriented soap producing unit in the South East Asia is setting up a new production facilities for their quality soap products.
The premises is expected to generate wastewater containing high amount of surfactants with high COD levels. Due to stringent discharge standards, the premises required to meet COD < 100 ppm treated effluent criteria.
- High levels of Surfactants present in the effluent
- COD as high as 10000-15000 ppm
THE SOLUTION - Soap industry effluent
Based on our previous experience with similar effluent containing surfactants, a treatment process using DAF and LEVAPOR IFAS process was suggested.
Soap industry effluent treatment scheme:
- Equalization Tank
- DAF with chemical dosing
- LEVAPOR IFAS Reactor
- Secondary Clarifier
Despite having high COD load and presence of surfactants with other solvents and active detergent products, the plant is achieving desired COD reduction of < 100 ppm at the outlet.
- Remarkable process stability despite presence of surfactants
- Consistent performance achieving COD < 100 ppm at the outlet of biological process
