The canteen and laboratory of every academic organization need a lot of clean water, and it generates equivalent amount of wastewater every hour which is neither purified nor reused. Due to water scarcity, the recycling and reusing of wastewater become very essential. The present study describes the simple and cost-effective method for the design of a small-scale wastewater treatment plant for the purification of wastewater generated by household, canteen and laboratory of an academic institute. The current study explored the process of phytoremediation by Typha latifolia L. and Canna indica L. for removal of metal ions and phosphate ions from the wastewater. The partially treated water after phytoremediation was further purified by sand filtration. The various water quality parameters (pH, hardness, dissolved oxygen, chemical oxygen demand, turbidity, total dissolved solids and metal ions) of the treated and untreated water were analyzed. It was observed that there are significant reduction in hardness, turbidity and chemical oxygen demand and increase in dissolved oxygen value. The treated water can be reused for various household works and agriculture.

每个学术机构的食堂和实验室都需要大量的净水，并且每小时产生的废水量相当，既没有被净化也没有被再利用。由于缺水，废水的回收和再利用变得非常重要。本研究描述了一种简单，经济高效的方法，用于设计小型废水处理厂，以净化学术机构的家庭，食堂和实验室产生的废水。目前的研究探索了香蒲和印度C的植物修复过程。L.用于去除废水中的金属离子和磷酸根离子。植物修复后的部分处理过的水通过沙滤进一步纯化。分析了处理过的和未处理过的水的各种水质参数（pH，硬度，溶解氧，化学需氧量，浊度，总溶解固体和金属离子）。观察到，硬度，浊度和化学需氧量显着降低，溶解氧值增加。经过处理的水可以再用于各种家庭工作和农业。
