Particle Size Optimisation of Sand to Improve Water Treatment Efficiency

1 Comment / Chemistry, Issue 14 / By

More efficient treatment methods must be developed for ensuring the future availability of drinking water. The purpose of this project was to determine how particle size composition can be optimized to improve the performance of sand as a natural, inexpensive, sustainable water filtration media.
Calibrated sieves were used to selectively remove specific particle size fractions from all-purpose sand. Permeation times, together with pH and calcium concentrations of filtered water samples were used to prove that the water filtration rate of sand can be increased by 65% by removing the <150 micron particle size fraction (11.3% by weight), while maintaining pH buffering performance.

Paramagnetic fluids optimization of the chemical synthesis of magnetite ferrofluids

Leave a Comment / Chemistry / By

Abstract Ferrofluids are paramagnetic liquids. The fluid is made up from a stable suspension of magnetic nanoparticles. This study investigates the synthesis of magnetite based ferrofluids with focus on the parameters of the precipitation of magnetite particles using iron(II), iron(III) and ammonium ions. Under the hypothesis that the precipitation speed and pH value had major …
