Bioremediation of Olive Mill Wastewater Using Free and Immobilized Pseudomonas aeruginosa: Efficiency and Phytotoxicity Assessment

Water and Environment Journal, EarlyView.
The graphical abstract compares the bioremediation performance of olive mill wastewater using P. aeruginosa immobilized in agar beads and fixed on activated carbon. Both systems effectively reduced chemical oxygen demand (COD), phenols, colour, phosphorus and lipids.

Extraction of extracellular polymeric substances (EPS) from anaerobic granular sludges: comparison of chemical and physical extraction protocols [PDF]

, 2010
International audienceThe characteristics of the extracellular polymeric substances (EPS) extracted with nine different extraction protocols from four different types of anaerobic granular sludge were studied. The efficiency of four physical (sonication,

Effect of inoculum and sludge concentration on viscosity evolution of anaerobic granular sludges

Water Science and Technology, 2005
The rheological behaviour of granular sludges (diameter 20–315 μm) originating from different anaerobic reactors was carried out using rotation tests. The sieved granular sludges suspensions display a non-Newtonian rheological behaviour and the limit viscosity was therefore used as a rheological parameter. The values obtained, which depend on the shear

Effect of recycling the slime layer extracted sludge on the sludge granulation

Gongye shui chuli
Recycling of extracellular polymeric substances(EPS) has been extensively explored. However, in-situ reuse of EPS-extracted sludge to the sewage treatment system has been rarely reported. After extracting the slime layer of activated sludge, the modified

Evaluating Oxygen Demand in Mainstream Anammox, A2O and Partial Denitrification/Anammox (PD/A) Processes: A Gradient‐Based Sensitivity Analysis

Water and Environment Journal, EarlyView.
This graphical abstract illustrates the oxygen demand reduction potential of the mainstream anammox process compared to conventional A2O and PD/A processes. It visually demonstrates maximum oxygen savings of 28.25% and 18.58%, respectively, under optimal conditions.

Statistical Optimization of Electrocoagulation on Membrane Fouling During Electrodialysis Process of Run‐Off Water Loaded With Road De‐Icing Salts

Water and Environment Journal, EarlyView.
This study optimized electrocoagulation as a pretreatment for electrodialysis of road runoff water affected by de‐icing salts. The optimized pretreatment effectively reduced suspended solids and turbidity, minimizing membrane fouling. Improved pretreatment enhanced ion‐exchange membrane performance and electrodialysis efficiency.

Granulation for Coking Wastewater Treatment in a Coupled Anaerobic-Aerobic Reactor

E3S Web of Conferences, 2018
A coupled anaerobic-aerobic granular bio-film reactor was employed with two operation stages: Stage I, granular sludge was formed from digestion sludge using brewery wastewater, and Stage II, granular sludge was acclimatized using coking wastewater.
