Abstract:

Sewage sludge management is one of the biggest concerns to the wastewater industry due to the increasing volumes produced and new stringent environmental regulations. Hydrothermal Treatments (HT) are a good option for converting wet biomass such as sewage sludge into high value products. However, HT are still not well developed when compared with other waste processing treatments. One of the most promising areas for developing hydrothermal processing applications is in sewage sludge treatment facilities. Sewage sludge has been identified as a potential feedstock for hydrothermal processing tha

Abstract:

Treated sewage sludge is often reused as a fertilizer but several European countries are phasing out this option due to concerns about harmful substances in the sludge. Valuables in the sludge should still be recycled so the removal of the pollutants is necessary. The technology in sewage sludge treatment remained nearly unchanged in the past century. Adapting traditional treatments and combining them with upcoming ones can be a way to separate substances in sewage sludge. This work discusses examples of how treatment methods can be combined and which potential these treatment combinations may

Abstract:

A greenhouse experiment was conducted at the University of Arizona, Tucson, Arizona, to study the effects of liquid sewage sludge loading rates on the vegetative growth, yield, and quality of barley grain and straw. Vegetative growth, grain yields, and straw yields were similar whether barley was grown with inorganic N or equivalent amounts of plant-available N from sewage sludge. Sewage sludge loading rates higher than three times the recommended plant-available N rate decreased barley stands in the seedling stage. The loss of stand was compensated for by higher tillering later in the season.

Abstract:

Dual Digestion is a two-stage system that combines autothermal thermophilic aerobic pre-treatment with conventional anaerobic digestion. The practicability of the system using pure oxygen is well proven. Disadvantages are the high cost of the pure oxygen and the absence of a detailed evaluation of anaerobic digester performance. This report discusses the results of a full-scale investigation into the dual digestion system (184m³ aerobic reactor and 1800m³ anaerobic digester), carried out in two phases: In the first using air alone for oxygenating the aerobic reactor and in the second using a c

The application of sewage sludge from wastewater treatment plants on agricultural soils has become an increasing practice in recent years, derived from its environmental benefits (recycling of organic matter and nutrients). However, there are a few studies regarding the risks and benefits for both the environment and the human health, probably because of the complexity of the problem and the high stakeholders’ expectations.

Sludge thickening and dewatering characteristics were found to worsen when increasing amounts of organic matter were incorporated into the sludge floe matrix.

Abstract:

Sewage sludge is currently being disposed by spreading it out on ﬁelds, an action that recycles important nutrients such as phosphorus, but also leads to heavy metal contamination. With impeding regulation changes, possibly making it harder or impossible to keep current practice, waste water treatment plants are reviewing their options. One solution could be mono-incineration with phosphorus recovery. However, to make the sludge have a heating value high enough to avoid support fuel it needs to be thermally dried, which requires large amounts of heat. Moreover, large investments would have to

Thesis (MPA.) -- University of Limpopo, 2017<br>The World Health Organisation (WHO) and World Bank (WB) state that worldwide access to sanitation has improved with countries in the north having 100% access to sanitation. However, only 64% of the world's population has access to improved sanitation. Sub-Saharan Africa has a noticeable improvement with South Africa improving from 73% in 2010 to 74% in 2014. They further estimate that $260 billion is lost globally each year due to lack of adequate water supply and sanitation. Universal access to water and sanitation would result in an estimated $

Thesis (MPA.) -- University of Limpopo, 2019<br>Polokwane Municipality is currently experiencing water shortages, which is affecting households and industries’ which is used to remove faeces and transport them to the sewage plant through sewer networks, as the system is waterborne. This research study aims at determining the status of faecal sludge management with the aim of developing a faecal sludge management projection plan for the City of Polokwane. The plan will enable the city to understand the current and future levels of faecal sludge production and it will also highlight the water de

To have a recycling system city with zero waste disposal as a goal is very important. For sewage sludge contains amount of nitrogen and phosphate to be applied for fertilizer or soil conditioner, contains organic matters to produce methane for energy and contains inorganic matters to be used for building material showed it can be a widely reused resource.

Abstract:

The advantages associated with the use of sewage sludge in agricultural land have motivated many countries to use sewage sludge for soil amendment purposes. South Africa’s deteriorated agricultural soil could benefit from this nutritional and cost effective product. However, the major shortcoming of sewage sludge is the presence of various pathogenic microorganisms. This raised concern amongst researchers with regard to public safety. The focus of this study, was to investigate the prevalence of pathogens in a crop grown in soil enriched with sewage sludge and to determine risk of infection th

Abstract:

abstract: Many manmade chemicals used in consumer products are ultimately washed down the drain and are collected in municipal sewers. Efficient chemical monitoring at wastewater treatment (WWT) plants thus may provide up-to-date information on chemical usage rates for epidemiological assessments. The objective of the present study was to extrapolate this concept, termed 'sewage epidemiology', to include municipal sewage sludge (MSS) in identifying and prioritizing contaminants of emerging concern (CECs). To test this the following specific aims were defined: i) to screen and identify CECs in

Submitted in fulfillment of the requirements for the degree of Master of Engineering, Department of Chemical Engineering, Durban University of Technology, Durban, KwaZulu-Natal, South Africa, 2017. .<br>One of the major effects of socio-economic change due to industrialisation is the generation of industrial wastewater, which requires treatment before being released into the environment. Laboratory-scale aerobic sequencing batch reactors under suspended-growth heterotrophic activated sludge were operated in different aeration configurations to study their effect on the treatment of wastewater
