The Problems in Achieving Sustainable Development in the Tannery Industry in Regard to Sewage Sludge Management
The paper discusses the issue of tannery sewage sludge management as one of the barriers in reaching sustainable development in the tanning industry. The Authors present the main characteristics, and its origins, of tannery sludge limiting the possibilities of their treatment and review the proposed solutions found in literature. The paper focuses on identifying the strong and weak points of the most commonly used methods used for sewage sludge treatment as well as presents some novel approaches which remain at laboratory stage.

Estudio de la dinámica poblacional de protistas, metazoos y bacterias filamentosas y su interpretación ecológica en fangos activos
El proceso de fangos activos es el sistema de tratamiento biológico más común en la depuración de las aguas residuales urbanas e industriales, siendo este un proceso biotecnológico donde interaccionan multitud de variables biológicas, fisicoquímicas y operacionales para la eliminación de contaminantes.

En la actualidad, los principales retos en el sector del tratamiento de las aguas residuales implican la necesidad de avanzar en el control y optimización de los procesos, que permitan encontrar nuevas estrategias y/o nuevos sistemas de tratamiento para el ahorro de los costes de explotación y el cumplimiento de los objetivos de eficiencia energética y calidad en las estaciones depuradoras de aguas residuales (EDAR).

Además, las restricciones impuestas por la normativa en el

Enviromental Ordination of Filamentous Bacteria in Activated Sludge
New strategies and/or biological treatment systems are in continuous development, in order to decrease the operationalcosts and to compliance the energy efficiency and quality objectives of wastewater treatment plants (WWTPs). One of thefrequently occurring operational problems in WWTPs is foaming and bulking (fig. 1a, b), which is mainly associated withexcessive growth of filamentous bacteria (fig. 1c). Studies about the dynamics of filamentous bacteria population inactivated sludge, often related to bulking and foaming episodes, have mainly focused on the elucidation of the taxonomicposition, in situ ecophysiology, presence and distribution, as well as strategies for controlling the populations. However, thepublished works about the biological process from the point of view of the enviro
