    摘要: A denitrification apparatus, for use in a wastewater treatment system having a mixed liquor source, is disclosed. The apparatus has at least two non-aerated continuous channels, connected in series. Wastewater flows from the mixed liquor source into the series of channels and then flows back into the mixed liquor source. In a preferred embodiment the inlets and outlets for each channel are arranged so that the flow into the channel is into the lower portion of the channel, and the flow from the channel is from the upper portion.

    摘要: A turbulence control system is provided comprising a first baffle, fixedly connected across the interior of an intra-channel clarifier having side walls between the side walls near the point of entry of wastewater into the clarifier, the first baffle covering a desired portion of the cross-sectional flow area within the clairifier; and a second baffle, fixedly connected across the interior of the clarifier between the side walls downstream of the first baffle and covering a desired portion of the cross-sectional flow area left uncovered by the first baffle. The turbulence control system may also comprise at least one accumulation baffle, connected between the side walls and near the bottom of the clarifier, the accumulation baffle extending upward to a desired height within the clarifier, but not so high as to produce a flow velocity which would impede settlement of sludge within the clarifier. Another possible feature of the turbulence control system comprises at least one guide vane, fixedly attached to the clarifier beneath its bottom and running parallel to the length of the clarifier. The turbulance control system may also comprise a pair of hinged wings mounted to the bow of the clarifier.

    摘要: A side skimmer provided in a channel containing flowing liquid includes a skimmer mechanism and a skimmer drain. The skimmer mechanism includes a fixed portion secured in a hinge-like manner to one side of the channel and aligned with an obstruction located partially across the channel width, and a movable wing-like portion extending above and below the liquid surface. This mechanism selectively deflects the flow into the drain, and is movable between a closed position, which allows free flow between the mechanism in the channel side and the obstruction, and an open position between the fixed portion and the obstruction, which directs flow to the skimmer drain. The skimmer drain is vertically movable between a closed position above the liquid surface, and an open position just below the surface whereby floating matter is removed.

    摘要: Used oil is refined by distillation to remove a volatile forecut followed by further distillation with recirculation provisions to obtain the desired fractions of lubricating oil products while reducing the vaporization temperature of the oil. The recycle effect tends to reduce coking and cracking while providing a greater recovery of lubricating oil products through the carrier effect of the light ends.In one embodiment of the invention, a waste oil feedstock has water, gasoline and other similarly volatile components removed in a first stage evaporator (16). Heavier fuel, such as fuel oil is then removed in a second stage evaporator (28). A light lube oil fraction is then obtained by distillation with a third stage wiped-film evaporator (40). Finally, a heavy lube oil fraction is obtained by distillation of the bottoms from the evaporator (40) with a fourth-stage evaporator (64).
