The evaluation of the efficiency of a commercial sludge digestor at a latex concentrate factory / Zatil Arumah Mohd Nawi

This study was to assess the efficiency of a commercial aerator (Aerob-A-Jet) which was claimed able to digest sludge. The study was carried out at the treatment ponds of a latex concentrate factory. It was found that the sludge depth in the first pond aerated by the Aerob-A-Jet aerator was reduced from 4 ft to 1 ft in 91 days. However, the other water quality parameters such as COD, BOD, ammonia were found to be very high in concentration and were not much reduced during the period of study. It is concluded that the low pH value of about 2.82 in the first pond is the primary cause of failure in removing the soluble pollutants in the first pond.
