Abstract
Abstract Liquid treatment apparatus, principally for effluent purification comprises a liquid basin with a suitable inlet and outlet, and a treatment space in which is disposed a lamellar insert construction forming a plurality of narrow, mutually parallel channels through which liquid flow is laminar and the axes of which are inclined to the vertical. For effluent purification the treatment space is a main sedimentation space downstream of a preliminary sedimentation space. The lamellar insert construction can be suspended from floats connected to a mobile dredger for movement with the latter.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
90 words
Lamellar structure with closed cells for the separation of foreign matter from liquids, or for the contacting of the liquid with a gaseous substance, or for the biological treatment or cooling of the liquid, comprising mutually parallel channels, the walls of the channels being circular so that the edges of the individual circles are disposed at the centers of the inside of the adjacent circular element forming closed cells therebetween, and the center point of the arcs coincide with every second intersection point of a notional square or rectangular matrix.
Claim 2
Dependent Claim
90 words

Claim 3
Dependent Claim
22 words
Apparatus according to claim 1, wherein the pitch or spacing of the said matrix is greater than the radius of the circle.
Claim 4
Dependent Claim
24 words
Apparatus according to claim 1, wherein the said partitioning elements are formed as a unitary component by being fixed together along their edge generatrices.
Claim 5
Dependent Claim
30 words
Apparatus according to claim 1, wherein the said partitioning elements are formed as a unitary component by being fixed together along their edge generatrices with the intermediation of planar plates.
Claim 6
Dependent Claim
24 words
Apparatus according to claim 1, wherein there are planar partitioning elements interposed between the circular cross-section partitioning elements along the lines of said matrix.
Claim 7
Dependent Claim
18 words
Apparatus according to claim 1, wherein at least some of said elements are provided with convex surface-increasing portions.
