Evaluating the Effectiveness of the Skimmer Versus the Perforated Riser in Sedimentation Basins
… transport from earth disturbance activities. Retention efficiency is used as a measure of a sedimentation basin's effectiveness. Several factors influence retention efficiency including the type of principal spillway used. The most common spillway is the perforated riser which dewaters the …

Droplet deposition on hydrophobic surfaces for agricultural sprays
… impacts and its applications in enhancing the retention efficiency of sprays. Large amounts of agricultural sprays are wasted worldwide, due to the poor retention on hydrophobic plants. As the harmful effects of pesticides in particular are more and more pointed out, there is an increasing …

The Biological Impact of High Throughput Continuous Bioprocessing
… of a sedimentation method of cell retention and its application in a fed batch designed ambr® micro scale bioreactor system. The work identifies periods of up to one hour required to perform the necessary sedimentation and media exchanges. In comparison, bench scale equivalent …

EFFECTS OF NITROGEN DEPOSITION ON BOREAL BOGS: A THREE YEAR NITROGEN FERTILIZATION AND TRACER EXPERIMENT
… This 15N tracer experiment revealed high retention rates of 15N by moss layers as expected. However, retention efficiency of moss layers declined over time and with increasing N deposition, indicating a leakier system as N deposition exceeds the critical load of Sphagnum moss. Aboveground …

Shear-Spun Polymer Nanofibres For Water Purification
… analysis of these doped nanofibres confirmed the retention of the nanoparticles and indicated retention efficiency greater than 80%. A variety of methods of nanofibre deposition (wet-laying deposition from slurry, drying and re-suspending, deposition under vacuum) were tested and examined, with …

Optimizing Phytoremediation to Enhance Treatment Efficiency of Suspended Raingardens
… Baby’™ (dwarf lomandra). The pollutant-removal efficiency of columns with a saturated zone (SZ) or non-saturated zone (NSZ) was tested for five different lightweight media bases: perlite, vermiculite, activated carbon, zeolite, and coconut coir. All columns were added with compost as a source of …

Experimental field studies and predictive modelling of PCB and PCDD/F levels in Australian farmed Southern Bluefin Tuna (Thunnus maccoyii).
… fillets of SBT were obtained. An assimilation efficiency, or percentage retention (efficiency expressed as a percentage), in the fillet of SBT is a measure of the uptake of a chemical residue from food (baitfish) to the SBT fillet. For the WHO-PCBs, assimilation efficiencies based on SBT …
