Sewage Sludge Treatment
Many wastewater treatment plants are coping with a waste stream of digested sludge. The sludge is normally dewatered by means of a centrifuge or belt filter press. After dewatering the sludge has a typical dry solids content of approx. 20 - 25%. Every country has a lot of problem with the fast increasing sludge, shortage of sewage treatment plant and limitation of landfill size. The volume is ...

Continuous Pyrolysis Facility for Sewage Sludge Treatment
The amount of sewage sludge is catastrophically increased in the latest few decades due to functioning of the municipal sewage treatment facilities. Dry sewage sludge contains 70-90% of the organic substances and 10-30% of the inorganic substances, which are dangerous for human health in case of inappropriate utilization. The continuous pyrolysis technology presents the unique sewage sludge ...

Co-fermentation of sewage sludge and biowastes
The anaerobic treatment of sewage sludge has a long history in Germany. It began early in the Twentieth Century with the development of the Imhoff tank and has, since then, been con-tinuously further developed. Today, anaerobic sludge digestion is the most widely used process for stabilizing sewage sludges. Digesters, in which a portion of the sewage sludge is converted into utilizable biogas ...

Thermophilic anaerobic digestion of sewage sludge with high solids content
The treatment performance of thermophilic anaerobic digestion (AD) of sewage sludge with high solids content was investigated with two laboratory-scale thermophilic anaerobic reactors (R1 and R2) with a feeding of pre-centrifuged sewage sludge. Reactor R1 was fed with sludge of 3.7% total solids (TS). The volatile solids (VS) removal ratio and methane yield in the stable state were ...

Dispose of sewage sludge
Sewage sludge treatment describes the processes used to manage and dispose of sewage sludge produced during sewage treatment. Sludge treatment is focused on reducing sludge weight and volume to reduce transportation and disposal costs, and on reducing potential health risks of disposal options. Water removal is the primary means of weight and volume reduction, while pathogen destruction is ...

Effect of lime addition during sewage sludge treatment on characteristics of resulting SSA when it is used in cementitious materials
Final disposal of sewage sludge is important not only in terms of satisfying the regulations, but the aspect of choosing the optimal wastewater treatment technology, including the sludge treatment. In most EU countries, significant amounts of stabilized and dewatered sludge are incinerated, and sewage sludge ash (SSA) is generated as a by product. At the same time, lime is one of the commonly ...

Sustainable reuse potential of municipal sewage sludge in south–east Australia
With the aim of reusing municipal sewage sludge, this paper presents the chemical and organic properties of sludge from a major sewage treatment plant in south–eastern Australia. The results show that the concentrations of all OCPs and majority of PAHs were below or close to laboratory detection limits. Concentrations of heavy metals in sludge samples were compared with typical sludge testing ...

Energy utilization in sewage treatment – a review with comparisons
In recent years, the operating cost of sewage treatment plants (STPs) in some parts of the world has been rising due to increases in the cost of energy. STPs have focused on energy reduction and recovery from treatment processes in order to lower energy consumption. The development involves the improvement of capital set-up for treatment plants in terms of equipment upgrading/plant sizing as ...

Methodology for the assessment of the greenhouse gas impact of wastewater sludge treatment
Nitrous oxide (N2O) and methane (CH4) emissions from the wastewater sector represent the second largest source of greenhouse gas (GHG) emissions of the waste sector. A protocol has been developed to measure GHG from sewage sludge treatment. GHG measurements were performed on two industrial sewage sludge composting plants. Measurement campaigns showed GHG emissions range between 0.18 to 3.40 ...

Sewage sludge treatment: evaluation of the energy potential and methane emissions with COD balancing
Sewage sludge is an important resource for the generation of electricity and heat within a wastewater treatment plant (WWTP). Taking a holistic approach to such use involves considering the greenhouse gas emissions. In particular, for anaerobic sludge treatment, methane emissions are a matter of concern. Therefore, the utilization of a carbon balance, based on the chemical oxygen demand ...

The Sludge treatment to solve the sewage problem
Sludge mainly comes from urban sewage treatment plants and industrial sewage treatment plants. It is the waste generated by sewage treatment plants For transportation and subsequent disposal, the sewage treatment plant will not leave the factory until the sludge is mechanically filtered. Generally, the water content is 80% or lower. Sludge is a heterogeneous body composed of organic fragments, ...
