一些传统的植物絮凝剂，如在辣木种子中发现的那些，已被观察到作为主要混凝剂，并被推荐用于非洲和亚洲农村地区的生活用水处理，那里的人们负担不起传统的混凝剂。一旦一种植物被证明具有突出的澄清特性，应用分类和选择性育种可以帮助确定更有效的絮凝剂的来源，并为特定情况生产最佳的“絮凝剂作物”。描述了识别潜在天然絮凝剂和管理作物的过程，以及使用植物材料优化简化水凝结的方法。包括21个参考资料、表格、图表和照片。

A few traditional plant flocculants such as those found in Moringa seeds have been observed to act as primary coagulants and have been recommended for domestic water treatment in rural areas of Africa and Asia, where people cannot afford conventional coagulants. Once a plant has been shown to possess outstanding clarifying properties, applied taxonomy and selective breeding can help in the identification of sources of even more potent flocculants and in the production of the best "flocculant crop" for a particular situation. The process of identifying potential natural flocculants and of managing crops, as well as methods of optimizing simplified water coagulation with plant materials, are described.
