Evaluation of the Efficiency of the Pulping Method in Simultaneous Reduction of Salt and Nitrate from Raw Water

Increasing water and soil pollution causes a lot of environmental problems. Meanwhile, different methods of controlling and decontamination of pollution with modern technologies have arisen, and these methods generally bring a lot of costs in a way that is not economical at times. One of the methods used to treat water and soil pollution is the use of plants, which is called purification plant. Identification of active and important plants in this field improves the efficiency and protection of the environment. The purpose of this study is to cultivate two aquatic species (bamboo and straw) in a laboratory environment to determine their ability to remove nitrate, salt and chlorine from raw water. For this purpose, NaCl and potassium nitrate with different concentrations in raw water and the absorption of the elements by the leaves of bamboo leaves and straw and the remaining amount of elements in raw water were measured on days 1 and 14. The results show that most bamboo plants are able to remove elements in raw water. So that at the highest concentration, removal of nitrate, sodium, potassium and chlorine are 46.28%, 32.62%, 24.73% and 27.98%, respectively.
