Effect of ambient temperatures on disinfection efficiency of various sludge treatment technologies

Sewage sludge produced during municipal wastewater treatment has to be treated efficiently in order to reduce impacts on the environment and on public health. In Germany and many countries, large quantities of sludge are reused in agriculture in order to recycle nutrients and organic material. In order to quantify the effect of different ambient temperatures on conventional and advanced sludge ...

Advanced processes for low rank coal drying and dewatering in high efficient power plants

During the combustion of high-moisture lignites (50?60 wt.%) in conventional power plants, a substantial amount of the energy content is required to evaporate the water. With a view to secure and strengthen brown coal's position as high available energy source, in recent years many attempts have been made to develop technologies for an energy-efficient drying or dewatering process. In this paper ...

Environmental assessment of different dewatering and drying methods on the basis of life cycle assessment

Sewage sludge is an inevitable product of wastewater treatment in municipal wastewater plants and its amount has increased dramatically due to the growing number of sewage systems users. This sludge needs to be adequately treated in order to decrease its hazardous properties and any negative influence on the environment. In this paper, gate to gate analysis, on the basis of life cycle ...

Aplication of Solar Energy for Drying of Sludge from Pharmaceutical Industrial Waste Water and Probable Reuse

Sludge, which is produced as a by-product of all treatment processes, has considerable potential as a fertilizer and soil conditioner. Many authorities now discharge the sludge after treatment directly to agricultural land in liquid form, while some others dewater and dry it first. In either case, with proper marketing, it is generally possible for an authority to earn revenue by this ...

CORK, Ireland: INNODRY 2E®–Complete sludge treatment solution including dewatering, drying and granulate storage

Cork WWP (Ireland) was designed in 2000. The specifications did require a complete sludge treatment solution including dewatering, drying and granulate storage. The system was to take maximum advantage of the biogas produced by digesters as well as any surplus heat used for the heating of the digesters. The drying equipment had to be flexible in order to cover the varying production rates and, at ...

Identifying energy and carbon footprint optimization potentials of a sludge treatment line with Life Cycle Assessment

This study exemplifies the use of Life Cycle Assessment (LCA) as a tool to quantify the environmental impacts of processes for wastewater treatment. In a case study, the sludge treatment line of a large wastewater treatment plant (WWTP) is analysed in terms of cumulative energy demand and the emission of greenhouse gases (carbon footprint). Sludge treatment consists of anaerobic digestion, ...

Corrugated Sheet Plant

The previous wastewater treatment was composed of the following chemicals: an acidic coagulant, caustic for pH adjustment, and an anionic polymer made down to 1% solution. The facility used 3-4 gallons of coagulant, 2-3 gallons of caustic, and 2-3 gallons of anionic flocculant (at a 1% solution) at a cost of $50/batch. The operator stated that they had low solids, they tended to overdose which ...

Dewatering Crews Keep the Alameda Corridor Dry and Open for Business

Griffin installed a multitude of deep wells along the alignment of the proposed railway to allow for construction. The discharge from the wells was pumped via large diameter high density polyethylene pipe (HDPE) to a below grade mixing vault, where a neutralizing agent was introduced to the groundwater as the quality of the groundwater was not allowed to discharge to the designated receiving ...
