【 摘 要 】

Kediri is well known as a city of cigarette, sugar refinery, and tofu industries. This condition has an impact on high waste disposal to the environment such as rivers. One of the cases in Dermo village Kediri, where the river water turned black and well water turn yellow, high turbidity and smelly when the factory worked. The solution to provide a healthy sanitary water is the use of membrane for filtering the water. Chitosan from Pila ampullacea shell, PVA and PEG were mixed to make a membrane. The purpose of this study was to analyze the effectiveness of chitosan membranes as polluted well water filters. Twelve samples of water collected from the wells at a distance in range 10 meters from the river aseptically. Then the water was filtered using the membrane that varies 1, 2, 3, 4 mm thickness. This research compared the water quality before and after filtered by membrane. Temperature, Total Dissolved Solid (TDS), pH, Dissolved oxygen, Dissolved CO2 and bacterial presence parameters were measured. The result show that chitosan membrane with 4 mm thickness had the most effective membrane to filter and provide the best water quality.
