Abstract EN
Turbidity is a common problem in river water that is usually treats through a processes coagulation and flocculation because it contains particles, colloids and plankton.
The aim of this study is to find out the possibility of using natural coagulants the rice husk and MO in order to remove or reduce turbidity and compare the results with the chemical coagulants used in water treatment plants (alum).
The experiment is conduct using a jar test.
Four different operation parameters were studied (coagulant's dose (0.05-1.5g), solution pH (2-12), practical size (600, 300, and 150 µm), and mixing speed (40-240 rpm).
The raw water sample (turbid water) prepared in lab with 200 NTU.
The results showed that the highest turbidity removal by rice husk and MO were 96.6% and 96.3% , respectively, at the coagulation's dose of 0.5g/L, pH 7, particle size 300 µm, and a mixing speed of 120 rpm.
While the alum efficiency was 97.0% at the coagulation's dose of 1g/L, Ph 6 and a mixing speed of 120 Turbidity is a common problem in river water that is usually treats through a processes coagulation and flocculation because it contains particles, colloids and plankton.
