OBJECTIVE Odorous compounds produced at the biosolids composting plant in Bariloche (NW Patagonia) attract a variety of insects, mainly belonging to the order Diptera. In order to characterize these flies, collected specimens were taxonomically identified, their community characteristics were described and their sanitary and synanthropic importance and autochthonous or introduced character were...

The use of fast growing trees could be an alternative in trace element contaminated soils to stabilize these elements and improve soil quality. In this study we investigate the effect of Paulownia fortunei growth on trace element contaminated soils amended with two organic composts under semi-field conditions for a period of 18 months. The experiment was carried out in containers filled with tr...

ABSTRACT Objective This study was aimed at evaluating pertinent physicochemical and microbiological (bacteria and parasites) parameters regarding the biosolids produced by the San Fernando wastewater treatment plant (WWTP) in Itagui, Antioquia, Colombia. Methods Twelve samples were collected and evaluated every month from January to December during 2010. The chemical, physical and microbiologic...

Abstract The continuous and rapid growth of sewage sludge (biosolids) from wastewater treatment plants (WWTPs) poses both economic environmental challenges. In many cities Russia, the situation has exacerbated with time. this study, three state-of-the-art biosolid management technologies, namely windrow composting (WC), tunnel (TC), lime stabilization (LS), were evaluated for their feasibility ...

Deep-row application of biosolids on reclamation sites is a unique alternative method of land application that solves many of the problems associated with surface application techniques. When combined with the growth of nitrogen-demanding hybrid poplar trees, it provides a natural recycling system that utilizes nutrients on-site, produces forest products and wildlife habitat, and reduces erosio...
