Jul 01, 2007 Ultrasound is a powerful and high frequency (⩾20 kHz) sonic vibration wave. It is possible to remove fine clay particles and iron coating on sand surfaces by using shearing forces of ultrasound (Taxiarchou et al., 1997, Tarasova et al., 2001). When it is generated in water or liquid countless micro-bubbles will be formed and destroyed.

Iron removing Principles and applications Nobel Srl

Brief description of the process. Iron can be contained in water as a dissolved matter or as a precipitate suspended. Obviously, the removal of suspended iron, normally consisting of ferric hydroxide, is not very complicated; it can be made by mean of a common mechanical filtration (mechanical sediment filters, sand dual media filters).

Iron removal from Turkish quartz sand by chemical leaching

The bioleaching of iron oxides by Aspergillus niger resulted in removal of 47. 70% of the total iron in the quartz sand, and suggested that this strain has not a good ability to remove iron impurities from quartz sand in comparison with chemical leaching. The iron content decreased from 0.315% Fe2O3 to 0.164% Fe2O3 in the bioleached quartz sand.

How to Dispose of Pool Filtration Sand Hunker

Some pool owners leave the sand in their filter indefinitely and rely on backwashing to keep it clean, but they are the exception. Filter manufacturers and pool maintenance pros recommend changing it every five years to ensure you get the maximum performance from the filter. Some filters hold 300 or more pounds of sand, which is a lot to cart to some off-site disposal area.
