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 ...

Study on cement mortar and concrete made with sewage sludge ash
This study investigated the feasibility of reusing wastewater sludge ash in construction materials to replace partial materials. Wastewater sludge sampled from thermal power plant was burned into sludge ash at 800°C in the laboratory. The sludge incineration ash has low heavy metal including Pb, Cd, Cr and Cu, so it belongs to general enterprise waste. The chemical composition of sludge ...

The impact of advanced digestion on incineration of sewage sludge
Abstract Traditionally, when incineratin sewage sludge, it was preferable to burn raw undlgested sludge, as digestion - by extracting some of the energy from sludge- subsequently reduce its calorific value. However, when considering incineration as part of a wider strategy, the desicion whether or not to include digestion becomes less clear. Since, virtually all of the requirements of ...

The treatment of sludge drying sewage
With the surge of sewage treatment capacity, the amount of sludge increases significantly. China's sludge is 38.2 million tons in 2015, 41.04 million tons in 2016 and is expected to exceed 50 million tons in 2020. Sludge is rich in organic matter, nitrogen, phosphorus, potassium and other nutrients, which has obvious utilization value. The high moisture content of sludge is the key to the ...

Management of sewage sludge and ash containing radioactive materials
Approximately 50% of the seven to eight million metric tonnes of municipal sewage sludge produced annually in the US is reused. Beneficial uses of sewage sludge include agricultural land application, land reclamation, forestry, and various commercial applications. Excessive levels of contaminants, however, can limit the potential usefulness of land-applied sewage sludge. A recently completed ...

Neptune project deliverable D4.3
Decision support guideline based on LCA and cost efficiency assesment The environmental sustainability assessments described in this report is based on life cycle assessments (LCA) of selected waste water treatment technology (WWTT) cases included in NEPTUNE. The basic approach in these assessments (avoided against induced impacts) is described in Deliverable 4.1 (Larsen et al. 2007) and other ...

Sludge reduction treatment in urban sewage treatment plant
Sludge is the sediment produced by wastewater treatment, including solid particles, such as sludge, sand, fiber, animal and plant residues and their solidified flakes, various colloids, adsorbed organic matter and metal elements, microorganisms, bacteria, insect eggs, weed seeds and other solids embedded in wastewater. The sewage sludge of the municipal sewage treatment plant is mainly composed ...

Pilot-scale experiment on thermally hydrolyzed sludge liquor anaerobic digestion using a mesophilic expanded granular sludge bed reactor
A pilot process of thermal hydrolysis combined with an expanded granular sludge bed reactor (EGSB) was carried out to evaluate pretreated sludge liquor into biogas conversion, process stability, and energy input/output balance. Approximately 25% of suspended solids of sludge were liquefied into aqueous phase during thermal hydrolysis pretreatment, which resulted in chemical oxygen demand ...

Analysis of Sludge Disposal Process and Pollution Control in Urban Sewage Treatment Plant
Based on the sludge incineration and disposal project of an urban sewage treatment plant in Changzhou City, this paper summarizes the main pollution problems and control measures in the process of sludge drying and incineration from the perspective of disposal technology, and provides a reference for the pollution control of similar projects. The wet sludge with moisture ...

Benchmarking energy consumption in municipal wastewater treatment plants in Japan
Reduction of greenhouse gas (GHG) emissions is one of the most important tasks facing municipal WWTPs. Electric power consumption typically accounts for about 90% of the total energy consumption. This study presents a benchmarking analysis of electric power consumption. The specific power consumption (SPC) ranged from 0.44 to 2.07 kWh/m3 for oxidation ditch plants and from 0.30 to 1.89 kWh/m3 for ...

Towards a complete recycling of phosphorus in wastewater treatment – options in Germany
Global reserves of mineral phosphorus are finite and the recycling of phosphorus from wastewater, a significant sink for phosphorus, can contribute to a more sustainable use. In Germany, Switzerland, and the Netherlands, an increasing percentage of municipal sewage sludge is incinerated and the contained phosphorus is lost. This paper reviews current technologies and shows that a complete ...

Incineration Industry: Scrubber on Sludge Incinerator Reduces Atmospheric Emissions - Case Study
Aberdeen Sewage Treatment Plant in Aberdeen, Washington started up their new Electric Infrared Incinerator in May, 1981. The sewage sludge incinerator, product of Shirco, Inc., needed a pollution control device in order to meet state, local and federal requirements for atmospheric emissions, according to the emissions test on the unit performed January, 1982. Chosen was a Model 24×24- ...

The sludge dryer can treat all kinds of sludge
Sludge is a collective term for various types of sediments and floating objects produced by different treatment processes in water supply and wastewater treatment. The composition and properties of the sludge mainly depend on the composition, properties and treatment process. According to different classification standards. There are many classification methods for sludge, which are briefly ...

The way of sewage treatment
Over the years, The company-SHINCCI has been working with a wide range of customers and business partners committed to define the most appropriate solutions for sludge drying. The necessity of sludge drying is that the sludge output of sewage plants is relatively large, and the volume of sludge must be reduced to facilitate subsequent transportation and treatment. Second, most of the domestic ...
