Abstract
Water is a vital resource for human survival and it is essential for sustainable development, hence access to safe drinking water is important to human existing. The water need to go through several treatments to make sure it is not contaminated and safe to be consume. One of the water treatment procedures is coagulation and flocculation process, it is essential process in water treatment and wastewater treatment by using chemical
coagulant such as Aluminium Sulphate (alum) as conventional substance. Alum is by far the most coagulant used in water and wastewater treatment, but however studies has shown that usage of Alum did give a bad impact to the health such as Alzheimer’s disease and other related health problems. A natural coagulant is preferred is because of its low price, bio-gradation, and it is readily available. This study is to find a potential of a natural coagulant using mango (Mangifera Indica) to function like any available conventional coagulant such as Alum, including the processing of mango kernel to become a powder as a natural coagulant. This study will be carried out by using jar testing experiment to investigate coagulation and flocculation using Mangifera Indica seed and Alum to three different water samples from sample one from Seri Serdang Lake, sample two from Taman Metropolitan Lake and sample three from Taman Cempaka Lake. Result obtained show that, Mangifera Indica has potential in removing water turbidity up to 85.45% removed and according to World Health Organisation (WHO) turbidity removal above 70% with natural coagulant is accepted. As for pH, the value is recorded is between 8.05 to 7.30 after the water treatment it is still in the range of neutral according to pH scale and according to WHO, the standard pH drinking water is between 6.5 to 8.5 is
acceptable. To conclude the uses of Mangifera Indica has potential as a coagulant in water treatment.
