The performance of vertical flow constructed wetland for grey water treatment as the efforts in preserving water resources

摘要

The problems of urbanization give an impact on environmental degradation due to the amount of untreated domestic wastewater, particularly grey water which pollutes the rivers. This study aims to determine the performance of the constructed wetland in treating grey water. The research was experimental research using vertical flow constructed wetland with Cyperus papyrus and Phragmites australis. The results showed that the vertical flow constructed wetland using Cyperus papyrus was able to lower the pH onto 21.95%, TSS onto 59.62%, COD onto 81.25%, BOD onto 82.67%, Nitrogen onto 75%, and the Phosphate onto 65% as well as filled up the effluent standard. Different results were shown by the vertical flow constructed wetland using Phragmites australis which was able to lower the pH onto 19.51%, TSS onto 50%, COD onto 78.52%, BOD onto 69.33%, Nitrogen onto 55%, and phosphate onto 54% and still was not able to fill up the effluent standard.
