Challenges in biological treatment plants: the approach of zero sludge waste
THEOFANIDIS S., Samiotis G., Bellos D., Pekridis G., Tsioptsias C., (Corresponding) Amanatidou E.
Topic:
Wastewater treatment
The current trend in operation of biological Wastewater Treatment Plants (WWTPs) is the minimization of sludge wastage due to its labor and cost intensive management process. Minimization of sludge can be achieved by increasing the solids retention time (SRT) in a WWTP, up to an almost complete...Read more
Pretreatment of antibiotics-contaminated waste biological sludge by ozonation
Boševski I., (Corresponding) Kalčikova G., Derco J., Žgajnar Gotvajn A.
Topic:
Wastewater treatment
Ozonation was studied as a pretreatment method for a waste biological sludge, contaminated with large amounts of globally used antibiotics; tiamulin, levofloxacin and amoxicillin. At the concentrations of over 100 mg L-1, these antibiotics were found to inhibit biogas production (up to 50%), which...Read more
Removal of heavy metals from sewage sludge using combined hydrothermal pretreatment and chelate extraction
(Corresponding) Usťak S., Muňoz J.
Topic:
Wastewater treatment
The removal of heavy metals from sewage sludge using the combined influence of hydrothermal pretreatment and chelate extraction was tested. The classical method of batch extraction with chelates and the advanced hydrothermal pretreatment (HTP) extraction process with chelates were compared. Both...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
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
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
