Soil Profile. There are different types of soil, each with its own set of characteristics. Dig down deep into any soil, and youâll see that it is made of layers, or horizons (O, A, E, B, C, R). Put the horizons together, and they form a soil profile. Like a biography, each profile tells a story about the life of a soil. Most soils have three major horizons (A, B, C) and some have an organic horizon (O).
At a pilot facility in Singapore, Siemens has cut the energy needed to desalinate seawater by more than 50 percent. The plant processes 50 cubic meters of water per day, consuming only 1.5 kilowatt-hours of electricity per cubic meter.
A desalination device essentially separates seawater (saline water) into 2 streams: one with low concentration of dissolved salts (the fresh water stream) and the other containing the remaining dissolved salts (the concentrated or brine stream).Seawater is pure water plus dissolved solids and gases.A 1-kg sample of saltwater typically contains 35-g of dissolved compounds, including inorganic salts, organic compounds from living organisms, and dissolved gasses.The solid substances are known as 'salts' and their total amount in the water is referred to by a term known as salinity (expressed as parts per thousand).eawater is pure water plus dissolved solids and gases.
