  • Patent number: 7992350
    Abstract: A column borne building construction according to the present invention comprises a building and one substantially vertical column for bearing the load of said building construction. The building has a polyhedron shape, this polyhedron shape having a top face defining a polygon shape by means of N1 top edges and N1 top vertices. The polyhedron shape comprises additional faces other than said top face, which additional faces are defined by additional edges and additional vertices. The top face is substantially perpendicular to the column and encircling the column. Each of the N1 top vertices join two top edges and at least one additional edge of the polyhedron. The column has a top coupling point and at least 3 of the N1 top vertices are connected to the column by means of a tension member. The extensions of these tension members coincide in the top coupling point.

  • Patent number: 6758972
    Abstract: The present invention relates to a method for treatment of wastewater. More particularly, the methods of the present invention are designed for the biological removal from wastewater of contamination in the form of insoluble suspended solids and soluble and insoluble organic and inorganic material, including nitrogen and phosphorus nutrients. A wastewater treatment process is described, which process is a hybrid continuous flow, cyclic operating, substantially constant level, activated sludge process with a symmetric functional cycle. In this functional cycle each compartment of a reactor is subsequently in a different functional phases, which functional phases are continuously separated: phase 1, phase 2, phase 3, phase 4, phase 1, phase 2, phase 3, phase 4, etc. . . . The symmetric functional cycle allows for symmetric (equal) influent distribution and therefore symmetric sludge and oxygen demand distribution.
