Sequenced Bioleaching and Bioaccumulation of Phosphorus from Sludge Combustion – A New Way of Resource Reclaiming –
© ThomĂ©-Kozmiensky Verlag GmbH (9/2011)
Reutilization of heavy metal contaminated solids, incineration ash in particular, is being increasingly problematic, since the use of ash in agriculture or construction industry is often not possible, due to its potential toxicity. Methods of bioleaching, known from ore extraction, may be used as an alternative remediation concept for heavy metal depletion in contaminated solids.

Batch system for study of Cr biosorption by dried waste activated sludge
© Aristotle University of Thessaloniki (6/2009)
Biosorption processes, defined as the sorption of metal ions by biomass, are being employed as an alternative technique for the decontamination of industrial effluents and for the recovery of the retained metals. Advantages of biosoption for removal of heavy metals over chemical and physical methods are; 1) Excess sludge from wastewater treatment plants may be used as bio-sorbent, 2) Low cost, free availability and possible reuse of the biosorbent, 3) High biosorption capacity because of large surface area, 4) Selective adsorption of metal ions, 5) Operation over a broad range of environmental conditions.

Micronutrients uptake by corn from Sewage sludge treated soils
© Aristotle University of Thessaloniki (6/2009)
In arid and some semiarid regions of Iran due to the shortage of organic matter,in soil, in one hand, and industrial production of organic fertilizers, on the other hand, the tendency toward the usage of sewage sludge (biosolid) has increased. Biosoild is rich in macro and micronutrients its application to the agricultural soils can promote growth and productivity of crops. One aspect of biosoild application as an organic fertilizer on agricultural farms is environmental pollution concerns such as heavy metals uptake by plans. The objectives of this research were to study the effect of biosolid applications (levels 0, 25, 50 Mg ha-1) to soils under corn plant.

Fate and effect of herbicides on co-composting process of green waste and sewage sludge
© Aristotle University of Thessaloniki (6/2009)
The fate and effect of herbicides such as linuron and metribuzin during sewage sludge and green waste co-composting were addressed in this work. A mixture of sludge and green waste was prepared at a ratio of 1:5 v/v. The mixture was split in four equal parts and the two herbicides were added, using a pressure sprayer, as sole or mixed pollutant in each of the three mixtures.

High performance filtration fabric units for sludge dewatering and containment
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2008)
Many industries utilize water for processing and for the movement and storage of by-products and waste. This results in large volumes of liquid or slurry-like materials being stored in impoundments, or being treated before discharge into lakes, rivers and streams. In the past, many industry by-products were discharged directly into water courses where they have settled, and over time, have contaminated the sediments of these water courses.

Potential peat replacement by vermicompost, a by-product of the earthworm industry

Vermicompost is a substrate that may be a component of potting media since it has a high microbial activity enhanced by the earthworms and enough nutrient content for the initial requirements of the plant growth.

GMF gouda paddle dryer for thermal treatment of dewatered sludge
© European Compost Network ECN e.V. (10/2008)
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%, which is very suitable for thermal treatment in a GMF-Gouda paddle dryer.

The environmentally sound and commercially feasible management of sewage sludge is a major issue that all European countries confront. Sewage sludge arises from the processes of wastewater treatment and represents one of the top priority waste streams.
