| Summary: | The GROW Technology for greywater treatment was installed at the MUET (Mehran University of Engineering & Technology), hostel and run under continuous flow conditions with hydraulic loading rate of 0.15m.d-1. The monitoring and analysis of influent and effluent water were carried out during January-December, 2010. Local plants species such as water hyacinth, Pennywort (duck weed), Mint and Cattail were used in the GROW rig as a mixed mode. Coarse Gravels were filled in the troughs as a medium. The collected samples were analyzed for BOD5 (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), TSS (Total Suspended Solids), pH, and DO (Dissolved Oxygen). Removal efficiencies of BOD5, COD and TSS were calculated as 83.0,69.0 and 84.0% respectively. DO was found increased from 0.6-3.5 mg.dm-3 while pH was observed between 6.5-7.8 |
