霉味化合物，某些种类的蓝绿藻的代谢产物，通常包含在水和藻类细胞体。发现后者固相中的化合物容易通过混凝和沉淀去除，而无需断点预氯化（中间氯化代替）。藻类的氯化导致代谢物含量人为释放到周围的水中。当大部分化合物存在于藻细胞体中时，在中间氯化处理中这些化合物的60%以上被去除。粉末活性炭处理在去除水相中的化合物方面是有效的。然而，在实际处理高浓度霉味时，其效果通常受到限制。另一方面，臭氧氧化和颗粒活性炭（GAC）处理被认为是一种有效的去除方法。结果表明，通过臭氧氧化和活性炭处理系统，其中包括混凝和沉淀没有预氯化霉味化合物被完全去除。
Musty-odorous compounds, metabolites of some species of blue-green algae, are usually contained in both the water and algal cell bodies. The compounds in the latter solid phase were found to be easily removed by coagulation and sedimentation without breakpoint prechlorination (intermediate chlorination used instead). Chlorination of the algae results in an artificial release of the metabolite content into the surrounding water. When a large fraction of the compounds was present in the algal cell bodies, more than 60% of these compounds were removed in the intermediate-chlorination treatment. Powdered activated carbon treatment is effective in removing the compounds in the aqueous phase. However, the effectivness was usually limited in practical treatment to high concentrations of musty odor. On the other hand, the ozonation and granular activated carbon (GAC) treatment was found to be an effective method for removal. It was observed that the musty-odorous compounds were completely removed through the ozonation and GAC treatment system, which included coagulation and sedimentation without prechlorination.
