Cleaning of foulants with enzymes has been considered more environmentally friendly compared to alkali cleaning. Cellulase was used to clean coconut milk foulants but the cleaning had to be done in two stages: cleaning by a surfactant followed by the enzyme. To simplify the enzymatic cleaning of coconut milk foulants, this work aimed to study effects of types of cellulase enzymes used on the cleaning efficiency. In addition, the work aimed to explore valuable components found in enzymatic cleaning effluents. Moreover, properties of the effluents, namely, TS, TSS, TDS, COD and pH were studied. The effluents from enzymatic cleaning had smaller TSS but significantly larger TS, TDS and COD compared to that from the cleaning using sodium hydroxide. However, the effluent from the cleaning by sodium hydroxide may be more difficult to treat, particularly when consider the pH of the effluent that was as high as pH 13. It was also discovered that all enzymatic cleaning effluents contained coconut oil, which could account for the high organic compounds in the effluents.
