Plantago ovata Medicinal Plant and Water Treatment

Plantago ovata is a medicinal plant of plantain, Plantaginaceae, family used to treat intestinal disorders and stomach diseases. P. ovata grain has relieving effects and healing inflammation and irritation of the mucous layer of stomach and duodenal ulcer. Beside the medicinal benefits, this plant is useful for water turbidity removal. Coagulation and flocculation are important processes in water treatment. Artificial coagulants are not useful from economic and health point of view. The objective of this study is to compare performance of chloroferric coagulant (alone) and with P. ovata coagulant aid in water turbidity removal. The experiments were done in turbidity of ۵۰ NTU. In all experiments the amount of chloroferric was ۱۰ ppm and optimum dose of P. ovata was ۰.۱ ppm at optimum pH of ۷. P. ovata at ۵۰ NTU turbidity, reduced turbidity up to ۹۴.۵% whereas chloroferric alone could reduce ۸۵.۱۶% of turbidity. Having been contained mucilage, protein and starch,P. ovata would reduce consumption of coagulants and be effective in water turbidity removal as a coagulant aid.
