Removal of ammonia in domestic wastewater by using multi soil layering

Abstract

Domestic wastewater is the primary source of river pollution. Every human activity in the house must produce waste. Domestic wastewater from the kitchen, bathing, and washing activities contains organic pollutants. The parameter tested was ammonia. In this study, Multi Soil Layering (MSL) was used as a processing method. This treatment serves to reduce ammonia levels in wastewater. This study aims to determine the removal of ammonia in greywater using the Multi Soil Layering System. Wastewater samples were taken in a residential area of Semarang. In this study, there are 2 stages, namely the preparation and implementation stages. In the seeding and acclimatization process, a batch reactor was used for 14-24 days running. The next stage is the process of running for 20 days with intermittent flow. Soil Mixture Box (SMB) is a mixture of andosol soil and activated charcoal (reactor A), andosol soil and apus bamboo (reactor B), and andosol soil, activated charcoal, and apus bamboo (reactor C). The results of domestic wastewater treatment using the MSL method respectively in the three reactors can remove ammonia by 49%, 51%, and 52%.

Rice Straw as a Sustainable Treatment Medium for Grey Wastewater: Case Study in Damietta, Egypt

“…The achieved good reduction of NH 3 concentrations from the investigated grey wastewater using treatment system type (A) might indicate a good adsorption capacity of the rice straw in addition to the sand and gravel media. The results of the current study revealed a high removal efficiency of NH 3 using treatment systems (A, B and D) in comparison with the results indicated by Wardani et al (2021), who demonstrated that the removal rates of NH 3 after utilizing a multi soil layering method by three reactors' relative to treat household wastewater with a percent removal of 49 and 51%.…”

Comparative analysis of greywater pollutant removal efficiency with horizontal free water surface flow wetland with other wetland technologies

“…Ammonia is a commonly found pollutant in wastewater, and its presence exceeding the discharge limits can have adverse impacts on aquatic ecosystems. It can result in heightened toxicity, imbalances in nutrients, and potential harm to aquatic organisms [ 22 ].…”

“…Table 2 shows the average range of the ammonia parameters for the untreated and treated greywater samples using different wetland technologies as observed, they range from 1.9 ± 0 (mg/L), 1.6 ± 0.1773 (mg/L), 1.7 ± 0.1553 (mg/L), 1.8 ± 0.0916 (mg/L), and 1.9 ± 0.034 (mg/L) for HSFS-CWT, VSSF-CWT, VFSF-CWT, and HSSF-CWT, respectively. Greywater ammonia is produced from the decomposition of organic kitchen waste [ 22 ]. The ammonia concentration in greywater samples is low, although the ammonia removal efficiency varied among different wetland technologies.…”

“…The dense fibrous root of the water Hyacinth used in this wetland may have contributed to its high removal efficiency. Other studies have also used adsorption techniques to remove ammonia [ 22 ], However, the degradation of plants in the system reduces the amount of dissolved oxygen, which affects the treatment efficacy. The removal efficiency observed in this study can be attributed to nitrification and plant uptake through a well-developed rhizosphere, as reported by Ref.…”
