The clamp consists of a base (11) with enlarged section (43) which increases its thickness (7). The enlarged section has, seen in plan view, a part circular shape or is V-shaped with rounded tip of 'V'. A ring (3) on a rod bent into a V-shape can hinge about a pivot point (26) in the enlarged section. One side of the enlarged section (43) has a groove (36) of part circular cross-section which matc...

A waste water purificn. process, in which intermediate clarification is effected between first and second activation stages and post-clarification is effected between the second activation stage and the sludge circuit, involves (a) operating the first activation stage aerobically or facultatively anaerobically mainly with prokaroytes in the functional biomass as an adsorption stage with a sludge l...
