The effect of incorporating biosolids on soil quality after cotton crop management
(Corresponding) Giannakopoulos E., Makrygianni E., Evangelou E., Salachas G.
Topic:
New solutions for a better and sustainable agriculture
pilot sewage sludge (also known as “biosolids”, BS) application of 7,000 kg/ha (dry weight) was performed in the area of Lamia prefecture, central Greece, in two fields cultivated with Cotton. BS was very rich in organic matter (75%) and had high concentrations of nutrients, with all heavy metals...Read more

Evaluation of real bilge water toxic effects on methanogenic activity
(Corresponding) Gatidou G., Samanides C., Vyrides I.
Topic:
Wastewater treatment
Bilge water (BW), an oily residue that is accumulated at the bottom of vessels, is mainly generated from pipes’ and engines’ leakage and consisted of lubricating and diesel oil, cleaning solvents, oily sludge and other hydraulic/engine spills from seawater filtrations as well as fresh and seawater...Read more
Regeneration of dissolved Fe(II) from Fenton sludge at a microbial fuel cell using a novel biocathode
(Corresponding) Wang G., Tang K., Jiang Y., Andersen H., Zhang Y.
Topic:
Advanced oxidation processes
Fenton reactions are widely applied for degrading recalcitrant pollutants, but the resulting ferric sludge remains a challenge. A novel concept for regenerating Fe(II) solution at pH 6 from ferric sludge generated in neutral Fenton is proposed. A microbial fuel cell (MFC) with biocathode and...Read more
Exploring the effects of static magnetic fields for the enhanced valorization of sewage sludge by anaerobic digestion
(Corresponding) Di Costanzo N., Cesaro A., Di Capua F., Mascolo M., Esposito G.
Topic:
Waste management
Anaerobic digestion (AD) is an interesting and sustainable option to handle sewage sludge (SS), as it generates a methane-rich biogas and a digestate with potential fertilizing properties. Several strategies have been proposed to enhance AD performances and the valorization of SS. Among these, the...Read more

Investigating the Performance of Anaerobic Co-Digestion of Primary Sludge and Acid Whey Using a Twin Pilot Scale System
(Corresponding) Gkoumas F., Tzivelou E., Gravanis Z., Mamais D., Malamis S., Noutsopoulos C.
Topic:
Waste-to-energy
Anaerobic Digestion (AD) has proven to be an effective method for transforming organic waste into biogas, a renewable energy source that can play a crucial role in reducing our dependence on finite fossil fuels. Despite its widespread use, mono-digestion, where a single substrate is utilized, is...Read more
Metagenomic Profile of Bacterial Community and Phage in Domestic Wastewater Treatment Plant
Nandar Htwe N., (Corresponding) Rollon A., Miyanaga K., Tanji Y.
Topic:
Wastewater treatment
For a better understanding of the microbial community and associated phage abundance in domestic wastewater treatment system, this study did a metagenomics profiling of bacterial community and phage in activated sludge process and chlorination system. The Phylum Proteobacteria is the most abundant...Read more
Improving the homogeneity of a sewage sludge-based phosphorus fertilizer by Monte Carlo simulation of the production chain
Vogt S., (Corresponding) Brueck F., Schnabel K., Weigand H.
Topic:
Solid waste management
Sewage sludge mono-incineration with subsequent phosphorus (P) recovery from the ash is becoming increasingly important in many European countries. Plant operators are facing the challenge to produce a homogeneous P output which needs to conform to fertilizer standards (including trace elements...Read more
Treatment of three agro-industrial wastewaters by dried bio-absorbent orange peels and brewery spent grains
Kiouranakis G., Ioannou Z., Gkatzionis K., Papanikolaou S., (Corresponding) Sarris D.
Topic:
Circular economy and industrial symbiosis
This study aims to determine the efficiency of reducing the phenol content (hence BOD/COD) of three agro-industrial wastes: olive mill effluent- olive mill wastewaters- OMW, brewery sludge – BS, and white wine lees – WWL by orange peel (OP) and dried brewer' spent grains (BSG). Orange peels...Read more
Understanding the alteration of organic pollutants and microbiome profiles in a petrochemical wastewater biotreatment process
Wu F., (Corresponding) Deng F., Liu S., Hose G., Simon G.
Topic:
Wastewater treatment
A better understanding of the alteration of organic pollutants and microorganisms in wastewater biotreatment processes is essential for the elucidation of pollutant removal mechanisms. This study investigated the alteration of organic pollutants, microbial communities and functional genes in a...Read more
Oxic-Settling-Anaerobic under intermittent aeration: effect on system performance, sludge minimization and greenhouse gas emissions
Dı Trapanı D., Cosenza A., (Corresponding) Bosco Mofatto P., Mannina G.
Topic:
Wastewater treatment
The paper presents the results of an experimental study carried out on a pilot scale activated sludge system operated under intermittent aeration and fed with real wastewater at the Water Resource Recovery Facility of Palermo University (Italy). The experimental campaign was divided into two...Read more
