Bio scouring vs Alkaline scouring | 12 Key Differences!

In textile industry, a huge amount of alkali is used every day for scouring purpose. But the unspecific use of these chemicals not only attack the impurities but also attack the cellulose of the fibers. This leads to certain loss of the strength properties. Again, the huge load of chemicals in the effluent water adds loads to the environments. The effluent water has high TDS, BOD, COD value and affects the environment tremendously. Bio-scouring is a smart and eco-friendly solution to all of these problems.

Difference between Bio scouring and Alkaline scouring


Alkaline scouring

Bio-scouring is done with enzymes

Scouring is done with alkali solution

Provides smoother surface profile


Cellulose with complete removal of impurities

Cellulose with complete removal of impurities and partial cellulose

No need of alkali neutralization

Requires alkali neutralization

Less washing cycle

More washing cycle

Less amount of TDS, BOD, COD


Completely eco-friendly

Not eco-friendly

No loss of fabric strength if controlled bio-scouring is carried out

Loss of fabric strength

Cost effective

Costlier than bio-scouring

Carried out at moderate temperature like 55°C

Carried out at boil temperature

No added chemicals are required

Added chemicals are required

Not suitable for removing seed coat fragments and motes and inability to remove waxes adequately

Seed coat fragment, motes, waxes everything removes completely
