“…Another study showed that different diseases such as Alzheimer's, Carcinogenic and neurotoxic health effects are considerably linked to chemical coagulants using in water treatment (Kurniawan et al 2020). A study has used Vigna mungo, Zea plants as natural coagulants to eliminate the turbidity from wastewater and recommended using these natural materials (Sasikala & Muthuraman 2017). It was reported that natural coagulants including Allium cepa peel ash, waste tea powder, Phyllanthus niruri, Vigna mungo and Zea were effectively used in turbidity removal between 70 and 97% for synthetic and surface water samples at neutral pH (Choy et al 2016).…”

For turbidity removal, most of drinking water treatment plants are using coagulants due to the presence of suspended and colloidal materials at the coagulation and flocculation units. Aluminium and sulphates salts are the widely used coagulants, such as Aluminium sulphate (Alum) and ferric chloride. However, several researches have linked Alzheimer's disease to the use of Aluminium sulphate. Hence, scholars have conducted several researches on the possibility to reduce the amount of Aluminium sulphate by using natural material/plants base as coagulant aids. In this study, Mallow's Leaves Extracts (MLE) and Carob's Pods Extracts (CPE) were used as an alternative coagulant aid. Couples of coagulation tests were implemented to find the optimal dosage of Aluminium Sulphates were used as coagulants. The results displayed that the maximum turbidity removal efficiency by adding 100% of each coagulant (i.e., Alum, MLE and CPE) were (61.16%, 51.175% and 37.12%), respectively. In addition, the minimum residual turbidity and maximum turbidity removal efficiency were 4.56 NTU and 97.72% by adding 22.5 Alum and 7.5 MLE presenting 30 mg/l dosing. Further, the minimum residual turbidity and maximum turbidity removal efficiency were 15.4 NTU and 92.3% by adding 22.5 Alum and 7.5 CPE presenting 30 mg/l dosing.
