Kitchen Greywater Treatment in a Constructed Wetland Microcosm Using Aquatic Macrophytes
Abstract Greywater or sullage is wastewater generated from households, commercial establishments and other sources that has not come into contact with faecal matter. In this study, greywater from a canteen kitchen was treated in microcosm-scale constructed wetlands which were designed as scaled-down models of free water surface (FWS) and vertical sub-surface flow (VSF) systems. Canteen greywater was made to flow through the microcosms planted with Phragmites australis or Phragmites karka or Ipomoea aquatica at an average hydraulic retention time (HRT) of 24 h. The kitchen wastewater was characterized by pH ranging from 2.48 to 6.25, phosphate (1.87–19.75 mg L−1), chloride (55–500 mg L−1) and sulphate (39.54–208.87 mg L−1). P. australis and I. aquatica were efficient in neutralizing pH and reducing phosphate, electrical conductivity, total dissolved solids and chloride contents in VSF model. Moderate sulphate reduction was observed in FWS model with P. australis and P. karka, with no reduction in VSF. Reuse of this greywater for gardening or toilet flushing could contribute towards recycling and conservation of water and protection of natural water quality in educational institutions, multi-storey housing, office and commercial complexes.
