摘要： A liquid solid separator tank has a motor driven recirculating belt having rollers placed therein processing a mixture of materials. The top belt brings wet materials into a collection trough having overflow weirs disposed externally. These weirs permit overflow liquids to flow down towards a main tank; then, a sump pump reintroduces water back into an influent basin to cleanse the mixture once again. Also, the action of a motor driven auger within the trough forces solids towards a dewatering box attached externally thereto. This box has a motor driven rotating cage mounted on moveable rollers and internally attached removable brushes that act to clean the outer surface of the cage as it moves in addition to a stationary high pressure wash. A shroud channels the influent liquid solid mixture towards a filtered water basin disposed directly underneath the lower belt portion permitting cleansed water to be removed therefrom.

摘要： Aspects of the present application relate to dewatering methods, systems, apparatus, and associated components thereof. In one implementation, a plow for a sludge dewatering system includes a blade. The blade includes a leading edge, and a first wing swept downward in a vertical direction and outward in a first horizontal direction relative to the leading edge. The blade also includes a second wing swept downward in the vertical direction and outward in a second horizontal direction relative to the leading edge. The second horizontal direction is opposite of the first horizontal direction.

摘要： This combined dehydration device continuously supplies primarily dehydrated sludge to a sludge supply part, the combined dehydration device including: a multiple rotary disk-type solid-liquid separation device and an electroosmosis dehydration device. In the multiple rotary disk-type solid-liquid separation device, a plurality of rotary shafts in which a plurality of rotary disks are fitted and mounted are arranged from the upstream side toward the downstream side and pivotally supported; while the rotary disks are rotated, water to be treated including sludge is supplied from over the rotary disks at the upstream side and is subjected to a primary dehydration treatment; and first dehydrated sludge on the rotary disks is fed and discharged from a sludge discharge part located at the most downstream portion of the rotary disks. In the electroosmosis dehydration device, a sludge supply part is provided at the upstream side of an endless filtration fabric spread between rollers.

摘要： A sludge dewatering system includes: a concentration apparatus that concentrates sludge while conveying the sludge on a top surface of a filter body; and a dewatering apparatus that subjects the sludge discharged from the concentration apparatus to pressure dewatering. The concentration apparatus includes: a filtering unit that subjects the sludge, which has been added with a first chemical agent, to gravity filtration; a chemical feeder that adds a second chemical agent to the sludge conveyed in the filtering unit; and a moving mechanism that moves the sludge, which has been added with the second chemical agent, in a direction intersecting a conveyance direction of the filter body.

摘要： A system and method for the separation of oil and water. Contaminated water is introduced into a settling and separating bowl through an inlet pipe. The contaminants float to the top and are recovered by a weir skimmer. The weir skimmer is fluidly connected to a recovered oil tank which receives the recovered oil. An oil separator filter belt is located in the separating bowl and separates the bowl into two segments: an upstream end on the side closest to the inlet and a downstream end on the opposite side of the inlet of the belt. The oil separator filter belt aggregates entrapped and entrained oil and other contaminants.

摘要： The present technology is directed generally to fluid treatment systems. In particular, several embodiments are directed toward filter supports configured to be positioned adjacent a filter belt within a filter belt filtration system. In one embodiment, the filter support can have a longitudinal axis generally parallel to the direction of movement of the filter belt. The filter support can include a plurality of struts spaced apart by a plurality of openings, and at least one of the plurality of struts extends across a portion of the filter support such that a longitudinal axis of the at least one strut is positioned at an angle with respect to the longitudinal axis of the filter support.
