Sludge production in wastewater treatment plants is increasing worldwide due to the increasing population. This work investigated the effects of ultrasonic (ULS), ultrasonic-ozone (ULS-Ozone) and ultrasonic + alkaline (ULS+ALK) post-treatments on the anaerobic digestion of sewage sludge in semi-continuous anaerobic reactors. Three conditions were tested with different hydraulic retention times ...
The principal cause of primary non-function in orthotopic liver transplantation is thought to be preservation injury to the microvasculature. We, therefore, evaluated if effluent levels of hyaluronate, whose uptake is an endothelial cell marker, could predict early graft function and ultimate graft outcome in orthotopic liver transplantation. A total of 102 cases were studied in two phases. In ...
The aim of this study was to investigate the performance of a two-stage fluidized bed reactor (FBR) system for the post-treatment of secondary wastewater treatment plant effluents (Shahrak Gharb, Tehran, Iran). The proposed treatment scheme was evaluated using pilot-scale reactors (106-L of capacity) filled with PVC as the fluidized bed (first stage) and gravel for the filtration purpose (secon...
The recent popularity of post-denitrification processes in the greater Paris area wastewater treatment plants has caused a resurgence of the presence of nitrite in the Seine River. Controlling the production of nitrite during the post-denitrification process has thus become a major technical issue. Research studies have been led in the MOCOPEE program (www.mocopee.com) to better understand the ...
The vinasse from ethanol distillery, which is a highly contaminating industrial waste, produced in large quantities. Through biotechnology, it can be used for the production of protein while reducing contamination. Candida utilis strain was isolated and adapted under different concentrations aqueous formulas vinasse, 10 to 50%. experimental trials were carried out lab using “batch” reactor with...
Methods In this study we performed a microarray analysis in a distillery Saccharomyces cerevisiae strain (BT0510) submitted to sublethal pressure treatment of 50 MPa for 30 min at room temperature, followed by incubation for 5, 10 and 15 min at room pressure (0.1 MPa). The transcription of the genes involved in central carbon metabolism in response to HHP was investigated for bioinformatics tools.

Article history: Received 21 October 2014 Revised 28 October 2014 Accepted 29 October 2014 Available online 23 January 2015 In this study, ultraviolet (UV) and vacuum ultraviolet (VUV) photolysis were investigated for the pre-treatment and post-treatment of coking wastewater. First, 6-fold diluted raw coking wastewater was irradiated by UV and VUV. It was found that 15.9%–35.4% total organic ca...
