Background: Considering the toxic effects of heavy metals and microbial pathogens in industrial wastewaters, it is necessary to treat metal and microbial contaminated wastewater prior to disposal in the environment. The purpose of this study is to assess the removal of heavy metals pollution and microbial contamination from a mixture of municipal and industrial wastewater using membrane biorea...

This paper presents the results of a study conducted on the treatment of combined sewer overflows using ferrate (VI) [Fe (VI)]. At a Fe (VI) dose of 0.24 mg/L, total chemical oxygen demand (TCOD), soluble chemical oxygen demand (SCOD), total biochemical oxygen demand (TBOD5), soluble biochemical oxygen demand (SBOD5), total suspended solids (TSS), volatile suspended solids (VSS), total phosphor...

In this study, the fully ripe fruits of Melodorum fruticosum Lour. were evaluated as material for red wine production. The effects of juice-to-water ratio (1:3 and 1:5v/v) and initial total soluble solids (18 and 20oBrix) on physico-chemical and sensory characteristics of musts and wines were examined. The results showed that during fermentation for 10 days the total soluble solids of all musts...

A feasibility study with three pre-conditioning times was carried out to examine the effect of anaerobic pre-treatment on phosphorus removal by aeration. The results showed that soluble phosphorus could be decreased from 120 mg L−1 to about 40 mg L−1 within one-day aeration. However, soluble phosphorus concentration was found not affected by pre-conditioning, but more pH dependent. Anaerobic pr...

A correct separation of solids from liquid fraction is crucial for a successful treatment of swine manure. For this reason an in-depth study of flocculant addition on different livestock wastewaters was carried out. Two flushed swine manure matrices, namely the mixture from nursery and feeder-to-finish pigs and the feeder-to-finish slurry alone, were tested for solids and nutrients removals fro...

Two-stage dilute acid pretreatment followed by enzymatic cellulose hydrolysis is an effective method for obtaining high sugar yields from wood residues such as softwood forest thinnings. In the first-stage hydrolysis step, most of the hemicellulose is solubilized using relatively mild conditions. The soluble hemicellulosic sugars are recovered from the hydrolysate slurry by washing with water. ...
