Phytoremediation model of greywater treatment in the Purwodadi Botanic Garden

Abstract

Water treatment of domestic wastewater/greywater to be reused and safe for environment are needed. In addition, bearing in mind that the need for water sources for the community is getting scarce, especially in dry season. Greywater treatment can be done naturally by using plants or known as phytoremediation. With this natural process, the operational costs for treating greywater is cheap. The potential of plants diversity in the Purwodadi Botanic Garden as a wastewater treatment in wetland model can be used as an education tool for visitors and has aesthetic value. The aim of this study was to provide a phytoremediation model for greywater treatment in the Purwodadi Botanic Garden. The method used wasdescriptive (quantitative and qualitative). Data collection was done through obtaining documents, conducting interviews, sampling and laboratory analysisof wastewater quality with parameters stated in Permen LHK 68/2016. The pond as a phytoremediation model in constructed wetland / floating wetland (CW / FW) functions as a propagation of aquatic plants, surface water and greywater treatment, educational facilities, and also recreation facilities. The developed pond is divided into three segments: Zone 1 pre-processing (inlet); Zone 2 processing (CW / FW) and Zone 3 post processing (outlet). The development of zone 3 can enhance the beauty of the landscape while ensuring the diversity of the biological community, as well as other tertiary treatment processing systems.
