Separation of Ultra-fine Wood Particles from Waste Water to Prevent Water Pollution
2003
Separation of ultra-fine wood and charcoal particles from industrial waste water was studied. Two waste water samples were generated from the production of synthetic charcoal plant. The general methods of ultra-fine separation, such as filtration, centrifuge and flocculation by polymers, failed to treat these samples. Particle size analysis, pH, zeta potential measurements, addition of metallic ions, mode of chemical addition and electro-coagulation were studied to separate the suspended particles. The addition of metallic ions, mode of chemical addition and electro-coagulation were found to be effective in this separation. The clean water produced was found to be suitable for re-use for many purposes.
