In recent years, the disposal of sewage sludge has been a major concern worldwide because their potential treat in relation with contamination ground water and food chain. Furthermore, poor mechanical properties don’t allow possible direct use civil engineering applications. For these reasons, it was important to explore more opportunity reuse this by-product treatment. frame, solidificationsta...

Sewage sludge is an important contributor to greenhouse gas (GHG) emissions and the carbon budget of organic solid waste treatment and disposal. In this case study, total GHG emissions from an auto-control sludge compost system, including direct and indirect emissions and replaceable reduction due to sludge compost being reused as fertilizer, were quantified. The results indicated that no metha...

The operation of an activated sludge process at a paper mill (AIPM) in Hedera, Israel, was often characterized by disturbances. As part of a research and development project, a study on new biological treatment was initiated. The study included the operation of three pilot units: a. anaerobic treatment by upflow anaerobic sludge blanket (UASB); b. aerobic treatment by two pilot units including ...

The interest in recovery and reuse by sludge fractionation has increased in recent years, largely due to environmental and political considerations. This article is a survey of the status concerning phosphorus recovery, looking into national policies and experiences in different European countries to find different factors influencing the development of phosphorus recovery. The ambivalence of s...

Residual solid in excess sludge treated by hydrothermal reaction was investigated as raw material for its recycling. Treated excess sludge and residual solid were also focused on their content change during hydrothermal reaction. Two kinds of excess sludge, obtained from a local food factory and a municipal wastewater treatment process, were tested under various conditions. Following hydrotherm...

Stone Brew Co. in Escondido, California, built a brand new brewing facility with a simple wastewater treatment system adjacent to a restaurant and one acre beer garden in 2005. After some significant production growth, the City threatened to significantly increase the water rate to be able to accommodate the higher organic strength and solids content in the water. This resulted in the installat...

The authors of the article consider problem formation huge volumes liquid toxic activated sludge in biochemical method residential area wastewater decontamination. At present, there are no effective technical solutions and technologies terms eliminating negative impact on environmental components. examines that allow to involve sludges reuse use them as fertilizers agriculture. A resource-savin...

Reuse of wastewater in agriculture is a common feature in the developing world. While this strategy might contribute to the livelihood of farming communities, there are health risks associated with the management and reuse of wastewater and faecal sludge. We visualise here an assessment of health risks along the major wastewater channel in Kampala, Uganda. The visualization brings to bear the c...
