Operational experience on paper sludge incinerator.

GEOSAF Position paper on operational safety

The GEOSAF Steering committee set up a working group dedicated on Operational Safety in 2010, considering that little work had been performed so far on that subject at the international level. This group was established to focus on hazards identification for the operational phase of a geological disposal facility and on the methodology used for the safety assessment. Both items are arguments in...

The effect of operational conditions on the sludge specific methanogenic activity and sludge biodegradability.

The effects of hydraulic retention time (HRT) and influent COD concentration (CODInf) on Specific Methanogenic Activity (SMA) and the biodegradability of an anaerobic sludge need to be elucidated because of the discordant results available in literature. This information is important for the operation of anaerobic reactors and design of the sludge post-treatment unit. For this study, sludge sam...

Research on Feasibility of Different Incineration Systems for Paper Sludge

A large amount of paper is recycled in China, that generates a significant amount of sludge and residue during the paper production process. Energy recovery by means of combustion in Waste-to-Energy (WTE) plants can be a possible candidate for sludge elimination. Currently, two incineration methods, distinguished as either direct incineration of partially dewatered sludge (generally 80% water c...

Incorporation of paper sludge in clay brick formulation: Ten years of industrial experience

Activated Sludge Treatment of Paper Mill Effluents

Introduction The pulp and paper industry is the second largest industrial water consumer in Europe with a usage of 35 m3/ton paper and a production of 85.2 M tons/year. Its effluents cause considerable damage to the receiving waters if discharged untreated since they have a high biochemical oxygen demand (BOD), chemical oxygen demand (COD) and contain chlorinated compounds, suspended solids (ma...
