Sentence examples for effect on settling from inspiring English sources
Sodium cations (<0.01 M) in the slurry favoured some degree of particle coagulation, whereas calcium cations had an adverse effect on settling rates even at low concentrations (<0.002 M), with the effects of a reduced bridging capacity most apparent in the lower MWs.
A subset of the nanomaterials evaluated in this study may prove to be a viable alternative to standard TiO2 nanoparticles for the removal of DBP precursors from drinking water, but the characteristics of the water matrix have important effects on settling efficiency and will require site-specific evaluation.
The effect of settling time on removal efficiency after EC has not been given due consideration so far.
And the results from experiments on effect of settle time show that immediately filtration of solution after reaction will not affect the absorption of AMP to radiocesium in seawater.
Air cleaners have been reported to reduce airborne pet allergen levels, but they have minimal effect on settled-dust allergen levels (Wood et al. 1998).
Particle size variation at tidal time-scales also directly affects the parameterisation of numerical sediment transport models through its effect on the settling velocity.
The coating design anticipated that this surface complexity would either have a deterrent effect on the settling stages of fouling organisms or would be unfavourable for adsorption and unfolding of adhesive proteins.
Feeding a more biodegradable influent to the selector (up to 45 g BOD g−1 VSS day−1) enhanced its effectiveness, whereas increasing the supply of particulate matter (up to 139.6 g COD g−1 VSS day−1) showed a negative effect on sludge settling.
Open image in new window Fig. 3 Wall effect on particle settling (Liu and Sharma 2005).
However, as shown by Pfeiffer et al. (2005), particle density has a second order effect on the settling velocity with respect to the particle dimensions.
