Colour Removal with the Sparac Process: Preliminary Results
نویسنده
چکیده
Following previous tests done on chemically regenerable carbon, Norit has developed a new grade of carbon that has faster adsorption kinetics. The effect of repeated cycles and chemical regenerations on the colour removal performance of this carbon has been investigated. Decolourisation trials were performed on brown liquor with a pilot plant supplied by Norit at the SMRI. Tests were carried out at 1 bed volume per hour (BV/h) at 80°C. Preliminary results show that calcium salt fouling can reduce the effectiveness of colour removal. The use of a pre-filter of spent carbon and different regeneration procedures is discussed. Overall the colour removal performance of SPARAC is lower than expected. Reasons for the poor performance are discussed.

Evaluation of Chemically Regenerated Activated Carbon (sparac) for Sugar Decolourisation
Norit Carbon has developed a chemically regenerable activated carbon (SPARAC) that is suitable for sugar decolourisation. Previous evaluation of this activated carbon showed promising results, and Norit developed another grade of SPARAC that had faster adsorption kinetics. This carbon has been evaluated in terms of its colour removal performance after successive regenerations. Decolourisation t...
متن کاملPerformance Evaluation of Hybrid Coagulation/Nanofiltration Process for AT-POME Treatment
The presence of lignin and its degraded products such as tannin and humic acids is the main reason causing the aerobically-treated palm oil mill effluent (AT-POME) to display colour at the point of discharge. In this work, a hybrid method is developed to treat the AT-POME sample that was conventionally treated by biological method. This hybrid method combines coagulation and nanofiltration (NF)...
