Basin classified

Lignite. Deposits generally classified as unconventional uranium resources occur in lignite and in clay or sandstone immediately adjacent to lignite. Examples are uraniferous deposits in the Serres Basin, Greece, North and South Dakota in the United States, and Melovoe in the CIS (17) (see... 

Special wastes. Wastes such as street sweepings, roadside litter, catch-basin debris, dead animals, and abandoned vehicles are classified as special wastes.

The chemistry of the Ebro River basin surface water can be classified using ternary diagrams (Piper diagrams, not shown). The main characteristics of the surface water of the Ebro River can be mainly summarised as Ca-SCL water type, some data plot in the Ca-HCC>3 field, they reflect water draining the upper part of the basin. In the Ebro surface waters, Ca varies from 30% up to 80% of the X 1 while Mg fluctuates from 5% up to 40% of the X+. The total concentration major cations (X+ = Ca2+ + Mg2+ + Na+ + K+) ranges from 3.4 to 11.5 meq L 1 with a mean value of 7.4 1.6 meq L-1 upstream in Mendavia, from 5.9 to 17.9 5 meq L-1 with a mean value of 10.8 2.5 meq L 1 downstream in Tortosa with a pick in Sastago (mean value X+ = 16.0 6.6 meq L ). These data are... 

The molecular space is divided into core and valence basins, the latter being classified according to their connectivity to the core basins as monosynaptic basins, associated with electron pairs, or dissynaptic basins, associated with covalent bonds. Moreover, an integration of the electronic population over each basin gives the number of electrons in each of them and the fluctuation between basins is related to the electronic delocalisation [39]. 

Fig. 4.19 Seasonal temperature observations in springs of the Penns Creek basin, central Appalachians (from Shuster and White, 1971). The authors classified the springs (text) into a conduit type with rapid karstic flow, and a diffuse type with slow flow through minute rock fractures. The former revealed significant seasonal temperature variations, whereas the latter manifested a steady temperature.

More than 1 million square kilometers of the Amazon basin may be classified as floodplain, wetland, or lake. These environments range from narrow, sporadically flooded lowlands bordering streams to massive, regularly flooded plains bordering the basin s largest rivers. Nearly 9000 lakes,...

Wastewater treatment systems can be classified, in addition to pretreatment, as preliminary, primary, secondary, and tertiary (advanced) treatments. Pretreatment of industrial wastewater is required to prevent adverse effects on the municipal wastewater treatment plants. Preliminary treatment is considered as any physical or chemical process that precedes primary treatment. The preliminary treatment processes may consist of influent screening and grit removal. Its function is mainly to protect subsequent treatment units and to minimize operational problems. Primary treatment is defined as the physical or chemical treatment for the removal of settleable and floatable materials. The screened, degritted raw wastewater from preliminary treatment flows to the primary clarification tanks, which are part of the primary treatment facilities. Secondary wastewater treatment is the process that uses biological and chemical treatment to accomplish substantial removal of dissolved organics and colloidal materials. The secondary treatment facilities may be comprised of biological reactor and secondary clarification basins. Tertiary (advanced) wastewater treatment is used to achieve pollutant reductions by methods other than those used in primary and secondary treatments. The objective of tertiary wastewater treatment is to improve the overall removal of suspended solids, organic matter, dissolved solids, toxic substances, and nutrients.
