A METHOD AND APPARATUS FOR PROCESSING WATER TREATMENT RESIDUALS
A method for processing water treatment residuals, or other amorphous aluminium oxide or aluminium hydroxide rich waste residuals, for use in the manufacture of hydraulic binders, comprising heating the residuals to remove water and oxidise organic material contained therein, comprising controlling the temperature of the residuals during heating such that they are heated to a temperature no higher than 800°C, more preferably no higher than 650°C, to ensure that aluminium compounds in the WTR, in particular aluminium oxide and aluminium hydroxide, remain in an amorphous state. The method may comprise controlling the temperature of the water treatment residuals such that they are heated to a temperature between 350°C and 650°C, more preferably between 400°C and 500°C.

A drainage mat (11) for a floor covering arrangement (1) set up on an underlying surface (4) has a plate- or sheet-shaped carrier layer (5) which has an underside (6) which can be laid on the underlying surface (4), and projecting formations (7) which are directed upwardly away from the underside (6), wherein upper sides (8) of the projecting formations (7) form a support surface (9). Fastened to the support surface (9) is a support layer (10) to which an adhesive material or mortar material (12) can be applied without interspaces (15) between the projecting formations (7) being filled by the applied adhesive material or mortar material (12). In the drainage mat (11), a respective base surface (19) of the upwardly projecting formations (7) has, on the underside (6), a length which is oriented along a drainage direction (17) and a width directed transversely thereto that is shorter than the length. In particular, the respective base surface (19) of the upwardly projecting formations (7) can have a droplet-shaped or lens-shaped contour. A circumferential line of the respective base surface (19) has no undercut projecting transversely to the drainage direction (17) along the drainage direction (17) by which liquid flowing along on the projecting formation is retained.
A height-adjustable supporting bearing (1) for floor covering elements which can be laid on a subsurface has a basic body (2), which is designed to be height-adjustable, and a support element (3) which is arranged on the basic body (2) in a variably tiltable manner, wherein the support element (3) has, on an underside (13), a bearing surface (14) which is zonally configured to be spherical cap-shaped and concave at least along an annular circumferential line and by means of which the support element (3) is supported on the basic body (2), wherein the support element (3) has, on an upper side (15), at least one support surface (17) for a floor covering element, and wherein the upper side (15) of the support element (3) is designed to be free of depressions. The support element (3) has, on the underside (13), a bearing surface (14) which is configured to be spherical cap-shaped and concave. The end region (11) of the basic body (2) has a bearing supporting surface (12) which is zonally configured to be spherical cap-shaped and convex at least along an annular circumferential line. The support element (3) has, on the underside (13), an engagement element (20, 27) which projects towards the basic body (2), said engagement element engaging with a cutout (21) in the basic body (2) and producing a captive connection between the support element (3) and the basic body (2) that counteracts a relative displacement.
The invention relates to a web-shaped or plate-shaped support element (1) for flexible, strip-shaped heating elements (7) of a surface heater, having contact regions (2), which form a flat contact surface (3) for placing the support element (1) flat on a base, and a plurality of guide forms (5), each having at least one side wall section, which forms a guide surface (14) for the heating element (7), which can be placed between the guide forms (5) on a heating element contact surface formed by the support element (1). A plurality of support forms (10) are designed in the heating element support surface, which form heating element supports for an arrangement wherein the heating elements (7) are spaced apart from the heating element contact surface, wherein the support forms (10) do not form a connection between two guide forms (5). The support forms (10) are designed and arranged spaced apart from all guide forms (5). The support forms (10) each have a curved support surface (11) for the heating element (7). The guide surfaces (14) of the guide forms (5) have undercuts (15) in order to fasten a heating element (7) contacting the guide surface (14).
A decoupling mat (1) for a surface covering structure that can be covered by covering elements has a strip- or plate-shaped compensation element (2) which has upwardly projecting formations (4) arising from a lower support plane (3), which formations form an upper covering plane (6) at a distance from the lower support plane (3) and are arranged spaced apart from one another and have at least in sections an undercut (8) along their periphery. A water-permeable cover is fixed on a bottom side (12) of the lower support plane (3) and prevents penetration by a viscous adhesive into the upwardly projecting formations (4). On at least some formations (4), the undercuts (8) are arranged along a region, extending in a curved manner, along a side wall of the upwardly projecting formations. A plurality of first undercuts (8) is oriented in a first direction and a plurality of second undercuts (8) is oriented in a second direction. The cover may have a perforation or consist of a water-permeable textile woven fabric or sheet, or of a water-permeable non-woven fabric (13). A plurality of adjacent formations (4) are respectively connected to one another by ventilation ducts (7) projecting from the lower support plane (3), wherein the ventilation ducts (7) do not extend up to the upper covering plane (6).
