Geneva, 5 September 2023 – The first-ever global data platform on sand and other sediment extraction in the marine environment finds that the marine dredging industry is digging up 6 billion tons per year, the equivalent of more than 1 million dump trucks per day. This is significantly impacting biodiversity and coastal communities.

Sand of different particle sizes is contained in a sand filterand at the bottom of a sand filter is a porous double bottom (collector). You can have sand filters ranging from very large tosmall, this is depending on the flow rate of liquid (usually water). The sand is often in a steel, plastic or concrete filter. How does sand filtration work?

As the temperature increases, so does the moisture level in the air. When you use your blast machine on a hot and humid day, the water vapor produced by your air compressor turns into droplets of water. These water droplets cause the abrasive to become wet. The abrasive flow, in turn, becomes uneven and can clog your machine.

Quartz sand, silica sand, anthracite coal, garnet, magnetite, and other materials may be used as filtration media. Silica sand and anthracite are the most commonly used types. When silica is not suitable (e.g., in filters following a hot process softener where the treated water is intended for boiler feed), anthracite is usually used.
