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.
Today China can desalinate 600,000 tons of water a day, but it aims to produce 2.5 to 3 million tons of desalinated water a day by 2020, mainly for use in the dry northern areas. However, desalination is expensive and requires energy, which, in turn, involves more water. Construction of the SNWDP.
