Sand and gravel are now the most-extracted materials in the world, exceeding fossil fuels and biomass (measured by weight). Sand is a key ingredient for concrete, roads, glass and electronics. Massive amounts of sand are mined for land reclamation projects, shale gas extraction and beach renourishment programs. Recent floods in Houston, India, Nepal and Bangladesh will add to growing global demand for sand. In 2010, nations mined about 11 billion tonnes of sand just for construction. Extraction
Problem & Hypothesis - Temperature of Sand vs. Water at the Beach

Veterans who were deployed to the Persian Gulf, Afghanistan and other dusty environments were often exposed to sand, dust, pollution and other airborne particles. Larger particles such as sand may become trapped in the nose and throat but can be expelled by coughing or sneezing. Very small, fine particles (particulates) may cause more serious health problems because they can be inhaled deep into the lungs and airways. These extremely small particles and liquid droplets can include acids, chemica

Sand can also be transported from beach to beach along a shoreline but this is mostly just a redistribution of sand that is already on the coast. The problem of beach loss can be exaggerated if sea level rises relative to the land (either due to true sea level change or geological sinking of the coast line).
Sand Separation Solutions now offers a high efficiency sand filtration system. Our system has two chambers to allow Operator to divert or by-pass flow from one chamber to the other keeping filtration going 100 percent of the time, while allowing maintenance and filter changes when necessary.
