Domestic wastewater reduction using constructed wetlands

Abstract

Domestic wastewater is household liquid waste that comes from sinks, bathrooms, and wastewater from washing machines. In Johan Pahlawan Sub-district, West Aceh District, the community and government's concern is still low towards achieving environmental health where the coverage of wastewater management has not been optimized. This is shown by people who do not manage wastewater properly. One of the alternative domestic wastewater management technologies is the concept of constructed wetlands with phytoremediation techniques. This study aims to determine the efficiency of reducing wastewater concentrations using phytoremediation with Eichhornia Crassipes plants, Pandanus amaryllifolius plants and Scirpus grossus plants. After the phytoremediation process with the concept of CWs-SF and CWs-SSF, it shows that the use of pandanus has not been effective in reducing contaminant levels in domestic wastewater. While Eichhornia Crassipes and Scirpus grossus plants are much better at reducing wastewater concentrations. The efficiency of reducing BOD values with a contact time of 3 to 9 days can reduce BOD levels by 80%-91%, COD and TSS can reduce the wastewater to 89%-90%, the temperature of the wastewater has been qualified with Eichhornia Crassipes and wlingen plants with 290C, and the pH of the wastewater has increased to 7.5-8.
