In primary effluent filtration (PEF), primary effluent is treated to reduce TSS, BOD, or other contaminants without resorting to secondary treatment in trickling filters or activated sludge basins. If PEF can meet the effluent quality requirements applicable to a wastewater stream, substantial cost reductions can be realized by using PEF instead of secondary treatment. In other instances, PEF c...

Using experimental data obtained from in vitro bioaugmentation studies of a sand filter community of 13 bacterial species, we develop an individual-based model representing the in silico counterpart of this synthetic microbial community. We assess the inter-species interactions, first by identifying strain identity effects in the data then by synthesizing these effects into a competition struct...

The decomposition of deposited CsI and iodine oxides (IOx) aerosols on sand bed a metallic filter has been pursued under irradiation at 120 °C. On the sand, it was found that are decomposed by temperature effect into an inorganic specie assumed to be molecular iodine. might due surface effects grains as usually stable this temperature. IOx expected well retained (DF > 100) long height is high e...

in this research, the effect of friction between the liquid metal and the sand mould wall and the effect of passage of liquid through a vertical bend and through a ceramic filter on the fluid flow and the melt velocity has been studied by measuring the velocity of the melt and direct observation of the liquid flow through the different parts of a naturally-pressurized running system. the fricti...
