Consequently, measures have to be taken in order to reduce/suppress the water pollution. In ord... Autori: Aurelia Caldararu, Lucian P.

Modeling and simulation of an ultrafiltration process for the removal of suspended solids and colloids from wastewater
Environmental Engineering and Management Journal › Vol. 9 › Nr. 3 Abstract
Mathematical modeling of the ultrafiltration (UF) process is motivated by the complexity of retention phenomena that occur during the UF in conjunction with the complexity of wastewater matrices submitted to ultrafiltration, as well as by the need to predict the process behavior in extreme conditions, such as high pollution loads for UF-membrane cleaning cycles optimization or for automated control of the process. Thus, series of laboratory-scale ultrafiltration experiments were perf... Autori: , George Barjoveanu ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=25630
Influence of innoculum acclimation in the biodegradation rate and estimated biodegradbility of cow manure, food waste and oil
Environmental Engineering and Management Journal › Vol. 9 › Nr. 3 Abstract
Two different inocula - acclimated and non-acclimated to fat- were used to evaluate the methane production of cow manure, food waste and oily waste in batch assays. The inoculum adapted to fat had a better performance in the methanisation of substrates with significant lipids content. Furthermore, it is demonstrated that an increase in the ratio inoculum/substrate can enhance the initial methane production rate of oily waste when using a non-adapted inoculum, improving also the ultim...

The aim of this work was the evaluation of the denitrification potential of a consortium of activated sludge adapted to anoxic conditions. As the carbon source is the main parameter influencing the denitrification process, in the first stage three carbon sources (acetate, citrate and glucose) were assayed in batch activity tests. The highest denitrification efficiency was ttained with acetate, being nitrate and nitrite completely reduced. The adapted sludge was then used as a potent...

Field-collected retort water was augmented with organics to obtain a range of initialCOD:SO42- ratios (0.5:1 to 2:1), and treated in two different MFC designs (tubular and two-chambered). The two-chamberedMFCs exhibited COD and sulfate removal 1 to 2 orders of magnitude higher than those of the tubular MFCs. The tubular ...
