"Spatial and temporal dynamics of suspended particles and E. coli in a complex surface-water and karst groundwater system as a basis for an adapted water protection scheme, northern Vietnam."

AbstractKarst aquifers in subtropical regions are characterized by high variability of water availability and quality due to changes associated with rainy and dry seasons. An additional challenge for water management is the combination of surface-water and karst groundwater systems since high spatiotemporal dynamics cause high variability of water quality. In these cases, adapted protection strategies are required. In this study, a protection approach for the catchment of a river-water diversion point in a rural area in northern Vietnam is developed. The variability of water quality was evaluated by rainy and dry season synoptic surveys of suspended particles and microbial contamination at 49 sites and time series at three sets of paired sites under constant hydraulic conditions. The anthropogenic land-use activities in the catchment were mapped to identify potential contamination sources and to highlight the challenging combination of surface-water and karst groundwater management. The analyzed data indicate differences in water quality between the dry and rainy seasons and a higher influence on water quality from land use than from hydrologic conditions. Furthermore, the results suggest a high risk of contamination resulting from residential areas, agriculture, and livestock farming, and reveal the necessity of implementation of appropriate measures such as restricted farming and the hook-up of buildings to municipal sewage disposal. Finally, the data show that water quality can be improved by adjusting water withdrawals by the time of day. The applied methods can be transferred to other surface-water and karst groundwater systems in similar subtropical environments.

Abstract The methods of sewage sludge management in Poland have largely been determined by the legal requirements related to the Poland’s membership in the European Union. Since 1st January 2016, sewage sludge landfilling is prohibited. It must be emphasised that legal changes regarding wastewater management, along with the systematic increase in the volume of produced sludge, entail the necessity to change the existing method of sewage sludge management. This paper contains an analysis of solutions for management of sewage sludge produced in Poland over the period of 8 years. The goal of the work was an assessment of comprehensive management of sewage sludge produced in Poland from 2009 to 2016. Despite the decrease in the agricultural use of sewage sludge, their average share of 32% was the highest among other forms of sewage sludge management in Poland. Another form, related with the final stage of sewage sludge management, concerned its thermal processing. It was treated as a promising method, with a 19% increase over the analysed period. An optimal solution should be found to ensure safe management of sewage sludge.

Many complaints were received from the residential area around the Shatin Sewage Treatment Works (STSTW) about the presence of odour. The dominant odour marker H2S was selected to be studied. A review of the odour measurement and sampling methods, together with the specification of the standard limits and health effects were made. The formation process of H2S was investigated and the abatement and control measures in terms of physical, chemical and biological techniques were compared. The monthly rate of H2S emission in the atmosphere was calculated from the soluble sulfide and the measured wastewater flow at the inlet works, primary sedimentation tanks, aeration tanks, and sludge digestive and storage tanks, and the H2S mapping was carried out at the same places. Meteorological data including wind speed, wind direction, temperature and pressure were collected. The effect of temperature and pH on H2S generation is shown, and the effectiveness of odour control and deodourization processes was studied. A Gaussian dispersion model of Industrial Source Complex version 3 (ISC3) was applied in predicting the ground H2S level at various air sensitive receivers in the vicinity of STSTW. None of the places exceeded the recommended H2S concentration of World Health Organization (WHO) and the odour is a localized problem in STSTW of 35% area having H2S ranging in 0.01--‐0.023ppm. Recommendations are suggested in both short-term improvement in operation and maintenance practice and long-term design and construction of sewage treatment facilities. published_or_final_version Environmental Management Master Master of Science in Environmental Management

The increased human population is threatening the natural water resources by reducing flows and deteriorating quality. High levels contamination of fecal microbes in Indian water resources is one of the worst impact on natural environment. The incomplete sewage treatment in existing STPs is the root cause it, along with disposal of untreated sewage. Fecal microbes even after the secondary treatment demands the further reduction, hence, an alternative method of vertical flow constructed wetland was adopted to examine the efficiency of the system. The study was aimed to primarily to suggest the suitability and comparative performance of wetland species, P. australis and C. indica. Study revealed the importance of fibrous rooting system of C. indica which helps to enhance aerobicity within the system and cause the reduced number of microbes. The additive enhancement of physical mechanism as well as competition among microflora within the wetland system and excretions from roots of C. indica plant might have been the reason of the significant highest removal of microbial indicators.

Resilient economic urbanisation growth in Tanzania signifies national increasing trend of solid waste generation that necessitates proper management. About 50% of Tanzanians suffer from intestinal schistosomiasis and soil transmitted helminths resulting from haphazard solid waste disposal. Various efforts to address solid waste management in Tanzania include establishment of public private partnership and major reforms in policy and regulatory frameworks. Despite these efforts, 60% of waste generated is mismanaged and normally disposed in illegal places along roadsides, sewage canals, and reserved open spaces. Cornerstone of proper solid waste management lies on separation of the waste at source. It is recommended that ‘the smart garbage collection bin' be adopted at community collection points and charging higher prices for generators who do not separate the waste.

In this chapter, we present the opportunities and general importance of woody biomass production (forests and short-rotation coppices) and waste management in a common system. Wastewater and different forms of sewage sludge, as energy- and nutrient-rich materials, can contribute to reaching resource efficiency, savings in energy, and reduction of CO2 emissions. Within certain limits, these woody plantations are suitable options for the environmentally sound disposal of wastewater and/or sewage sludge; in addition, they can facilitate the realization of full or partial energy self-sufficiency of the wastewater plant through bioenergy production. Focusing on circular economy, we introduce the aspects of the treatment process and the sizing issues regarding the municipal wastewater treatment and the woody biomass in a complex system. Based on a specific case study, approximately 826 ha of short-rotation coppices (with a 2-year rotation) are required for the disposal of sewage sludge generated by a 250,000 population equivalent wastewater treatment plant. If we look at the self-sufficiency of its energy output, 120–150 ha of short-rotation coppices may be adequate. This complex system can replace the emissions of around 5650 t of CO2 through electricity generation alone and another 1490 t of CO2 by utilizing the waste heat.

This paper presents qualitative evidence to support the application of microwave induced plasma gasification (MIPG) technology for converting municipal solid wastes (MSW) to syngas and to use it for enhanced oil recovery (EOR). The target for the case study of this paper is the United Arab Emirates, which is a major producer and exporter of petroleum. The main EOR method employed by the UAE’s oil companies is the miscible gas flooding method, whereby natural gas or carbon dioxide is injected into the oil reservoirs to boost the oil pressure, reduce the viscosity of the oil and to increase the pumping rates. UAE purchases natural gas for power production and EOR from its neighbor, Qatar, which makes the UAE a net importer of natural gas and a major consumer of energy, while reducing the national income from the oil sales. The UAE is looking at ways to boost its oil production and to reduce the usage of natural gas, including the injection of carbon dioxide, nitrogen and steam generated by concentrated solar power. UAE and the other Arabian Gulf nations have some of the highest per capita rates of production of domestic waste. Landfilling is the prevalent form of waste disposal for industrial, commercial and residential waste. Incineration-type waste-to-energy power plants are being constructed, but they are not the most effective solution due to cost and environmental reasons. This paper proposes a solution that covers the two problems with one technology, namely MIPG of MSW. MIPG is shown to be the most efficient method of gasification available, as it uses much less energy for producing and sustaining the plasma than other techniques, and produces a much cleaner syngas than thermochemical gasification schemes. The syngas can be used for electricity generation or for making fuels and raw materials in the Fischer-Tropsch or similar processes. In this proposal, MIPG will be used to turn MSW, sewage sludge and biomass wastes into syngas. A part of the syngas will be used to produce electricity to power the petroleum extraction processes, while the carbon dioxide formed in this combustion of syngas can be captured and used for EOR in deep oil wells, which also functions as a form of sequestration of carbon. In addition, syngas can be turned into methane and synthetic natural gas using the Fischer-Tropsch or Sabatier process and then pumped into the oil wells. Some of the petroleum extracted can also be gasified using the MIPG method for the production of synthetic natural gas. Thus, the dependence on natural gas imports will be eliminated, while also achieving zero landfill targets.
