Abstract
This study was carried out to determine the significant differences in the quality of collected rainwater before and after filtration and to evaluate the quality of filtered water through physical/chemical and microbiological examination as well as to evaluate the discharged capacity and efficiency of the filtering system. The study was conducted at the Don Mariano Marcos Memorial State University, NLUC on the month of October 2009 - March 2010.
The collected rainwater was gathered from the Rainwater Harvesting System
located at Nillo’s Residence at Barangay Sapilang, Bacnotan, La Union.
The significant difference in the quality of collected rainwater before and after
filtration depends upon the result of the water analysis in physical/ chemical and microbiological analysis. Based on the result of the study, the water samples before filtration was almost met the set standard for drinking purposes. After the filtration, result revealed that the developed filtering system was not efficient as a filtering media for rain water harvesting system (RWHS) as for drinking purposes.
The discharge rate of the filtering system was highly affected by the components of layers of the materials. White sand has faster infiltration rate and discharge rate which has a rate of 23.81 ml/sec at 940 cm depth of water. Meanwhile, the fine sand has the lowest infiltration rate and discharge rate which is 13.16 ml/sec at the depth of 940 cm depth of water.
