Constructed floating wetland with mooring system technology to improve water quality in Gedebage Reservoir, Bandung

Abstract

Gedebage Reservoir is built as retention ponds, in the future it will be developed into an integrated religious tourism area, so that the quality of water reservoir must suitable for tourism. Constructed floating wetland with mooring system, besides being used as water quality improvement technology, it will also add aesthetic value. The purpose of this study was to identify the possibility of applying the constructed floating wetland in the Gedebage Reservoir area. This study uses secondary data to determine the design parameters and characteristics of water sources, design parameters are used for location recommendations, while the characteristics of water sources are to determine the accuracy of the technology used. The result shows that the placement of a floating wetland technology with mooring system in Gedebage reservoir has meets the requirements of design parameters than in a biological filter channel. The characteristics of the Gedebage Reservoir water source that have not met requirements consist of several parameters, namely: Ammonia, Chlorine, Mn, DO, Sulfide, Detergent, Oil and Fat, Cd, Pb, DO, BOD, COD, Fecal Coliform and Total Coliform. Whereas, based on the ratio of BOD5 / COD in the dry season that ranged from 0.25 indicating that the water had been toxin, so that it would disrupt the development of biofilms, so in addition to wetland, a pre-treatment was needed before entering the reservoir.
