Drying characteristics of biosludge from pulp and paper mills

Influence of drying of biosludge on organochlorine compounds from pulp and paper industry.

Pulp and paper industry is one of the major sources of man-made generation of organochlorine compounds. During biological treatment of wastewater, part of organochlorine compounds is discharged with treated effluent and part is retained on biomass and disposed of as waste activated sludge. Due to presence of these compounds, the disposal of biosludge from pulp and paper industry has become an i...

Evaluating the effect of enzymatic pretreatment on the anaerobic digestibility of pulp and paper biosludge

Anaerobic digestion of biosludge has not yet been implemented in pulp mills due to low biogas yields. Enzymatic pretreatment of biosludge has shown improvements in biogas yields but results are varied. A key limitation of previous studies is that they fail to consider the COD contribution from the enzyme solutions. The aim of this study was to systematically investigate the potential for enzyma...

Anaerobic treatment of activated sludge from Swedish pulp and paper mills--biogas production potential and limitations.

The methane potential of activated sludge from six Swedish pulp and paper mills was evaluated. The methane production potential of sludge samples ranged from 100-200 NmL CH4 g(-1) volatile solids (VS) and for four of the six sludge samples the potential exceeded 170 NmL CH4 g(-1) VS. The effects of sludge age and dewatering on the methane production potential were evaluated. The effects of enzy...
