Performance of IPAG60 for the treatment of turbid water from Lake Cibuntu, Cibinong

Abstract

Water is the main need of all beings. People need water to fulfil their daily needs such as drinking, bathing, washing and other sanitation activities. The more population, the more activities that require water, so the greater the need for clean and or drinking water. Indonesian people require an average of 144 L/day/person of water. The level of clean water services in various regions in Indonesia is still relatively low, 45.85% in average, especially in the marginal area. Most of the water treatment plant in marginal areas cannot produce viable clean/drinking water, both in quality and quantity. Lake Cibuntu is a small artificial lake located in the Cibinong Science Center, Cibinong. It used as raw water for Peat Water Treatment Plant (IPAG60) and whose all measured parameters close to the required standard of the Regulation of Ministry of Health No 492/2010. This study aims to determine the performance of IPAG60 in treating water from Lake Cibuntu into clean water based on physical, chemical and biological parameters. Results showed that the quality of producing water meets the standards. The performance of efficiency achieved is 95% and can be maintained for 3 months of operations. Comparative studies between producing water from IPAG60 and local water company (PDAM) showed that the production water of IPAG60 has better quality. In case of water color, produced water from IPAG60 has a color level of 4 NTU, while tap water from PDAM has a color level of 11 NTU.
