Effect of Cellulase and Protease Pretreatment on Dewaterability of Waste Activated Sludge from Paper Mill

open access: yesBioResources, 2014
The feasibility of cellulase and protease pretreatment to improve the dewaterability of waste activated sludge from papermaking (WASP) was evaluated. Dewatering properties such as capillary suction time (CST), dry solids content of the sludge cakes from ...

Moderate‐Temperature Hydrothermal Treatment Removes Detectable DNA and Antibiotic Resistance Genes From Municipal Sludge While Preserving Resource Value

open access: yesWater and Environment Journal, Volume 40, Issue 3, Page 484-494, August 2026.
This graphical abstract shows the overall study design where dewatered wastewater sludge samples were collected and subjected to a range of HT temperatures. Measurement of nucleic acid concentration and antibiotic resistance gene profiles across temperatures showed that HT at moderate temperatures offers sustainable, scalable sludge sanitation and ARG ...

Dewatering Characteristics of Oily Sludge

open access: yes, 1993
Proper sludge conditioning facilitates better dewatering of sludges. Sludge conditioning techniques required for different sludges bigbly depend on the properties of the sludges.

Sewage sludge conditioning with the application of ash from biomass-fired power plant

open access: yesE3S Web of Conferences, 2018
During biomass combustion, there are formed combustion products. Available data indicates that only 29.1 % of biomass ashes were recycled in Poland in 2013.

Struvite Production From Wastewater: Effect of Magnesium‐to‐Ammonia Ratio and Stirring Velocity on Precipitation Efficiency and Settling Behavior

open access: yesCLEAN – Soil, Air, Water, Volume 54, Issue 7, July 2026.
This study demonstrates that stoichiometric Mg2+:PO43− excess (1.1:1) and slow 10‐min dosing are critical for maintaining low supersaturation, yielding large crystals (>0.84 mm) and rapid settling (5.5–10.1 cm/min). This strategy optimizes nutrient recovery (≥80%) and solid–liquid separation without flocculants, proving viable for complex industrial ...

Effect of cytostatic drugs on microbial behaviour in membrane bioreactor system [PDF]

open access: yes, 2010
The aim of this work is to evaluate the influence of cyclophosphamide and its principal metabolites (CPs) on microbial behaviour in a membrane bioreactor system. Two laboratory-scale membrane bioreactors (MBR) were run in parallel with a sludge retention

The Influence of the Addition of Cement and Zeolite on the Increase in the Efficiency of Sewage Sludge Dewatering in the Pressure Filtration Process

open access: yesEnergies
The process of removing water from sewage sludge is particularly important due to its high content in the raw sludge. This translates into problems with the transport and storage of sediments.

Dewatering of septic tank sludge in alternative sludge drying bed

open access: yes, 2020
In dewatering of septic tank sludge, the sludge drying bed is one of the main techniques used, but it demands a great deal of area and time for the removal of sludge cake.

The anaerobic digestion of sugar beet pulp

open access: yes, 2014
World-wide there are substantial quantities of sugar beet pulp, which arises as a residue after the processing of whole beet to extract sugar for refining as a foodstuff or for use in fermentation, in particular for the production of ethanol for the ...

Wastewater Sludge Dewatering Enhancement by Flocculant Selection and Electrochemical Pretreatment

open access: yesSeparations
In wastewater treatment, sludge is generated during both the primary and secondary sedimentation processes. With the growing volume of wastewater, sludge production has increased accordingly.
