Erodibility of hill peat
(Teagasc, 2006-06-30)
The energy necessary to entrain soil in water depends on the soil strength. Once entrained, the settling velocity of the eroded soil in water is of fundamental importance to the processes of sediment transport and deposition. ...
Nitrification in a vertically moving biofilm system.
(Journal of Environmental Management, 2006-06-01)
A laboratory continuous feed biofilm reactor, comprising a bulk fluid reactor, a biofilm plastic module, a feed tank, pneumatic devices and controls, was operated for a total period of 257 days, including seeding time, to ...
A novel hybrid filter for the treatment of septic tank effluent
(ASCE, 2006)
Intermittent sand filtration is a common and effective method for treating septic tank effluent. However, if the loading rate is too high, clogging and ponding of the sand filter surface layer can occur due to the accumulation ...

Denitrification of a nitrate-rich wastewater using various wood-based media materials
(2006)
This laboratory study examined the use of various wood materials as a carbon source in horizontal flow filters to denitrify nitrate-nitrogen (NO3-N) from a synthetic wastewater. The filter materials were: sawdust ( Pinus ...
