Abstract

Melati air has aerenchyma which plays an important role in the process of transferring oxygen to the rhizofer to qualify the oxygen demand in constructed wetland system. In this research, the Sub Surface Vertical Flow Constructed Wetland (SSVF CW) system was built to determine the effect of the depth of the Echinodorus palaefolius's rhizofer on the quantity of dissolved oxygen (DO) in the SSVF CW system. This system was designed to treat domestic wastewater with HRT of 4 days. SSVF CW was built using soil and stones of 1-2 cm, 2.5-5 cm, 7-10 cm as media. This study shows that melati air with an average root length of 47.25 cm and the longest root of 60 cm was able to influence DO concentration in the system. The removal efficiency of TSS, BOD, total ammonia, and phosphate was 93,48%, 89,39%, 59,39%, and 66,53% respectively. Whereas nitrate and TDS didn't decrease which could be possible due to the well running of nitrification process.

Abstract

Textile wastewater that is discharged directly can cause damage to aquatic ecosystems and affects human health, thus requiring an effective alternative wastewater treatment. This research was conducted using a hybrid method that aims to eliminate pollutants in textile waste. The study was conducted by flowing textile waste into the bottom ash filtration and proceed to constructed wetland system with the residence time of 4 days. The results showed a decrease in the value of TDS, TSS, COD, and chromium by 16.47%, 97.09%, 72.14%, and 94.78% respectively in bottom ash output; and 13.12%; 57.53%; 7.52%; and 0.35% in the constructed wetland output. Therefore, the use of the hybrid method has been effective in treating textile waste by looking at the decrease in each test parameter.

Abstract

The wastewater produced in the hospital originates from activities carried out in the hospital, such as domestic waste, clinical waste, and laboratory waste. It contains many coliform bacteria. The bacteria were dangerous if it pollutes the environment because it can be the human’s disease. In general, hospitals have implemented wastewater treatment systems using disinfectants as tertiary treatment. Disinfectant itself can endanger the environment if used continuously. In addition, the use of disinfectants costs a lot. Therefore, this study uses a constructed wetland system as an alternative of the tertiary treatment using Echinodorus palaefolius. The results obtained from studies using this system are the percentage effectiveness of decreasing total coliform, BOD, nitrate, and phosphate. The removal efficiency of the total coliform, BOD, nitrate, & phosphate was 96,17%, 62,92%, 69,98%, & 63,53% respectively.
