Moringa oleifera is a plant whose seeds have coagulation properties for treating water and wastewater. In this study the coagulation efficiency of Moringa oleifera kept in different storage conditions were studied. The Moringa oleifera seeds were stored at different conditions and durations; open container and closed container at room temperature (28 degrees C) and refrigerator (3 degrees C) for durations of 1, 3 and 5 months. Comparison between turbidity removal efficiency of Moringa oleifera kept in refrigerator and room temperature revealed that there was no significant difference between them. The Moringa oleifera kept in refrigerator and room temperature for one month showed higher turbidity removal efficiency, compared to those kept for 3 and 5 months, at both containers. The coagulation efficiency of Moringa oleifera was found to be dependent on initial turbidity of water samples. Highest turbidity removals were obtained for water with very high initial turbidity. In summary coagulation efficiency of Moringa oleifera was found independent of storage temperature and container, however coagulation efficiency of Moringa oleifera decreased as storage duration increased. In addition, Moringa oleifera can be used as a potential coagulant especially for very high turbidity water.
辣木是一种其种子具有用于处理水和废水的凝聚特性的植物。在本研究中，对保存在不同储存条件下的辣木的凝聚效率进行了研究。辣木种子在不同条件和持续时间下储存；在室温（28摄氏度）和冰箱（3摄氏度）中的敞口容器和密闭容器中分别储存1、3和5个月。对保存在冰箱和室温下的辣木的浊度去除效率进行比较，结果显示它们之间没有显著差异。在两个容器中，保存在冰箱和室温下1个月的辣木的浊度去除效率均高于保存3个月和5个月的辣木。发现辣木的凝聚效率取决于水样的初始浊度。对于初始浊度非常高的水，获得了最高的浊度去除率。总之，发现辣木的凝聚效率与储存温度和容器无关，然而，辣木的凝聚效率随着储存时间的增加而降低。此外，辣木尤其可作为处理浊度非常高的水的潜在凝聚剂。
