background detergents and difficulties of their presence in the water and wastewater cause various problems such as foam production, anomalies in the growth of algae, and accumulation and dispersion in aqueous environments. objectives the aim of this study was to examine and compare the moving bed biofilm reactor with another reactor without media (carries) for anionic surfactants removal. mate...

Excess sludge production is one of the limitations biological activated process. Therefore, study’s objective to upgrade MBBR process an integrated fixed film-activated (IFAS) reduce excess production. Two scenarios were followed in this study eliminate process: first, modifying moving bed biofilm reactor (MBBR) system by increasing solid retention time (SRT) from 5 15 days; and second, upgradi...

ANITATM Mox is a new one-stage deammonification Moving-Bed Biofilm Reactor (MBBR) developed for partial nitrification to nitrite and autotrophic Nremoval from N-rich effluents. This deammonification process offers many advantages such as substancial reduction in aeration requirement and sludge production along with the lack of need for an external carbon source. In this paper, we present the ex...

The most essential limitation of batch-injection analysis (BIA) methodology compared to other flow methods (CFA, FIA, SIA) is the lack of possibility of on-line sample processing in the measuring system. Some procedures of on-line sample pretreatment in BIA are possible by changing the plastic tip of the automatic micropipette used for sample injection into a flow-through reactor, e.g. by packi...

Intermittent aeration process can be easily applied on the existing activated sludge system and is highly reliable against the loading changes. It can be operated in a relatively simple way as well. Since the moving-bed biofilm reactor method processes pollutants by attaching and securing the microorganisms on the media, the process efficiency can be higher compared to the suspended growth biol...

Abstract The aldol reaction of bio acetone in presence a strongly basic ion exchange resin was carried out with and without the addition water temperature range between ? 30 °C 45 °C. conversion, selectivity service time resins were investigated stirred batch reactor continuous fixed bed reactor. For experiments, both conversion increased decreasing temperature. Furthermore, to medium has posit...
