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.
0.66 kcal / liter is the minimum energy required to desalination of one liter of seawater, regardless of the technology applied to the process. It is interesting to compare this energy to the heat required to boil one liter of water and condense its vapors.
