“…This might constitute an effective means of removing nutrients from effluents and the harvested plants can then be used directly as fertiliser or added to compost. Another investigation by Bakare et al [37] in a community in Durban found that greywater from different households varied significantly and could not be easily treated through biological processes or technologies because of low mean Biochemical Oxygen Demand (BOD):Chemical Oxygen Demand (COD) ratio. Currently the Pollution Research Group (PRG) of the University of KwaZulu-Natal (UKZN), in Durban, is conducting a study on the evaluation of duckweed and Azolla spp.…”

Challenges and Opportunities for Sustainable Urban Farming in South African Low-Income Settlements: A Case Study in Durban

2019

Growing urban centres have been attracting ever higher numbers of rural migrants, including small-scale farmers, looking for better opportunities due to the rise of large-scale farming, loss of land and climate change. Consequently, there has been an increase in the number of spontaneous and informal settlements being constructed as cities do not keep up with the planning and infrastructure development for new arrivals. Urban dwellers in informal, unplanned settlements where issues of land tenure and access to services are prevalent have, consequently, been exposed to precarious living conditions with limited access to food and water scarcity. Urban agriculture (UA) strategies have been adopted by those residents to alleviate poverty and food insecurity, and have been seen to perform other functions, such as environmental, social, cultural and developmental. This study explores challenges and opportunities for sustainable urban farming as an integrated environmental management strategy for the upgrading of informal settlements in three case studies in Durban. This paper demonstrates the need for municipalities to support community driven processes to ensure sustainability of UA initiatives and sustained investment for maintenance. Policy makers need to create an enabling environment for academics, non-governmental organizations (NGOs) and the private sector to co-develop water efficient solutions to manage the food-water nexus and capitalise on localised community structures and groups, such as co-operatives and women groups.

“…Bacteria phyla with a relative abundance above 1% included Proteobacteria (36.0%), Planctomycetes (15.4%), Chloroflexi (9.7%), Bacteroidetes (7.7%), Firmicutes (4.4%), Acidobacteria (2.5%), Actinobacteria (1.8%) and Synergistetes (1.3%). These phyla were also identified by other researchers as the dominant bacteria phyla for wastewater treatment [ 14 ]. It is reported that Proteobacteria, Bacteroidetes and Firmicutes are dominant bacteria phyla in a conventional active sludge process and also in a hydrolysis system.…”

Low-energy cost wastewater treatment is required to change its current energy-intensive status. Although promising, the direct anaerobic digestion of municipal wastewater treatment faces challenges such as low organic content and low temperature, which require further development. The hydrolysis-aerobic system investigated in this study utilized the two well-proven processes of hydrolysis and aerobic oxidation. These have the advantages of efficient COD removal and biodegradability improvement with limited energy cost due to their avoidance of aeration. A pilot-scale hydrolysis-aerobic system was built for performance evaluation with actual municipal wastewater as feed. Results indicated that as high as 39–47% COD removal was achieved with a maximum COD load of 1.10 kg/m3·d. The dominant bacteria phyla included Proteobacteria (36.0%), Planctomycetes (15.4%), Chloroflexi (9.7%), Bacteroidetes (7.7%), Firmicutes (4.4%), Acidobacteria (2.5%), Actinobacteria (1.8%) and Synergistetes (1.3%), while the dominant genera included Thauera (3.42%) and Dechloromonas (3.04%). The absence of methanogens indicates that the microbial community was perfectly retained in the hydrolysis stage instead of in the methane-producing stage.

“…Previous research discussed three main things, namely greywater treatment, greywater content, and greywater impacts. Several studies on the processing and utilization of greywater address filtration techniques regulated by gravity and disinfection for household use [20] and double filtration greywater processing in slum areas [21] research on greywater content includes greywater content in households [22,23], characterization and pollutant loads of Greywater in urban slums [24], specification and treatment of domestic wastewater [17], and greywater treatment strategy based on a local on-site greywater treatment system in households or the so-called 'autonomous water management [25]. The applied greywater treatment technologies in households efficiently render Greywater for agricultural uses in adequate volumes [26].…”

The Impact of the Environment and People’s Attitudes on Greywater Management in Slum Coastal Settlements

et al. 2022

The rapid population growth in many countries will ultimately impact the provision of essential services and engender many challenges, such as inadequate sanitation. Indonesia has an extensive coastline and densely populated coastal areas that have grown sporadically, creating slums. These areas have long been associated with poor greywater management. Greywater is dumped into beaches, roads, and yards without pre-treatment, thus harming the environment and society. This study aims to identify various factors influencing community actions to manage and overcome greywater-related problems in coastal slum areas. Using methods by combining qualitative and quantitative approaches. The influential factors in the physical condition of the built environment, the natural environment, community activities, and government involvement related to greywater were analyzed qualitatively, while the public understanding of greywater management was assessed quantitatively. The results showed that these four factors significantly influenced people's attitudes towards wastewater treatment. The findings show that these four factors affect people's mind-set about handling greywater, which becomes an obstacle to changing their attitudes and views on greywater. The four factors have the same level and cannot be separated in dealing with greywater. Treatment strategies are in accordance with coastal nature, settlements physical conditions and communities are then chosen Treatment Horizontal Flow. Doi: 10.28991/CEJ-2022-08-12-05 Full Text: PDF
