◉ Introduction to Sediments
Sediment is any particle that can be moved by fluid flow and eventually becomes a layer of solid particles under water or other liquids. Sediments accumulate in rivers, oceans and lakes. Simple gravity avalanches produce sediments characteristic of rubble piles, landslide deposits, and karst collapses. Each type of sediment has a different settling rate, depending on its size, volume, density and shape.
◉ Sediment Analysis Range
Water system sediments, surface sediments, marine sediments, soil sediments, suspended sediments, drum sediments, pipeline sediments, river sediments, etc.
◉ Sediment Analysis Project
Composition analysis, particle size analysis, elemental analysis, inorganic nitrogen analysis, mercury content analysis, heavy metal speciation analysis, bulk density analysis, sedimentation velocity analysis, moisture content analysis, sulfide analysis, qualitative analysis, etc.
