Abstract A laminated settler for settling solids present in a liquid in a tank, in which the liquid to be settled is fed into compartments defined between a plurality of laminae slanted in relation to the vertical and consisting of laterally slanted and unslanted surfaces, in which settler the liquid to be settled flows upwards, sediment settles therefrom under the effect of gravity onto the slanted surfaces and further flows onto the unslanted surfaces of the laminae, said settler having a feeding groove at the lower end of the laminae and open only to said compartments, which feeding groove extends only over part of the width of said slanted surfaces, collecting troughs at the upper end of the laminae for receiving liquid coming through the compartments and from which the sediment has been settled, and a sediment funnel under said compartments for receiving the separated sediment, said sediment funnel extending under the unslanted surfaces of the laminae and thus laterally beyond the feeding groove. Preferably, the width of the upper surface of the feeding groove opening to the compartments is from 20 to 80 per cent of the width of the laminae.
A LAMINATED SETTLE FOR SETTLING SOLIDS PRESENT IN A LIQUID IN A TANK INTO WHICH THE LIQUID TO BE SETTLE IS FED, SAID SETTLE COMPRISING A TANK HAVING UPPER AND LOWER END PORTIONS, A PLURALITY OF LAMINAE POSITIONED IN SAID TANK IN A SLANTED RELATION TO THE VERTICAL AND IN SPACED PARALLEL RELATION TO EACH OTHER TO DEFINE COMPARTMENTS THEREBETWEEN IN WHICH THE LIQUID TO BE SETTLE FLOWS, SAID LAMINAE EACH HAVING A FLAT SURFACE PORTION AND AN INCLINED SURFACE PORTION WHICH EXTENDS ANGULARLY TO THE FLAT SURFACE PORTION GENERALLY LATERALLY OF THE DIRECTION OF FLOW OF LIQUID THROUGH SAID COMPARTMENTS: A FEEDING GROOVE IN THE LOWER END PORTION OF THE TANK OPEN ONLY TO SAID COMPARTMENT BETWEEN THE LAMINAE AT THE LATERALLY INCLINED SURFACE PORTIONS THEREOF, SAID GROOVE HAVING AN UPPER DISCHARGE EDGE LOCATED AT THE SAME LEVEL IN THE TANK AS THE LOWER OF THE LAMINAE AND EXTENDING ACROSS ONLY THE SURFACES LATERALLY INCLINED SURFACE PORTIONS OF THE LAMINAE, SAID UPPER END PORTION OF THE TANK HAVING AN OUTLET OPENING AT SUBSTANTIALLY THE SAME LEVEL AS THE UPPER ENDS OF THE LAMINAE AND COLLECTING TROUGHS AT THE UPPER END PORTION OF THE TANK ADJACENT SAID OUTLET OPENING AND THE UPPER ENDS OF THE LAMINAE FOR RECEIVING LIQUID, FROM WHICH THE SEDIMENT HAS BEEN REMOVED, AS AN OVERFLOW THROUGH SAID OUTLET OPENING FROM THE COMPARTMENTS BETWEEN THE LAMINAE, AND
