DYNAMIC SEPARATION AND FILTRATION
20170296946 · 2017-10-19 ·

A modular, compact, mobile, dewatering and liquid-liquid separation and filtration system. The system processes incoming influents of slurries, solids and liquids at a high speed of operation and in large volumes. System is capable of being modularly scaled, allowing for a continuous steady state operation accommodating any slurry flow rate in a synchronous dynamic equilibrium process. Components and modules integrated into the system include a dynamic filtration clarifier 101 (DFC), a nested-filter dewatering cell 115 (NDC) and/or a compression filter press 125 (CFP). The DFC performs the primary dewatering phase of separating the primary water from the solids creating sludge. The NDC further breaks apart the solids of the sludge, removing interstitial water in a secondary dewatering phase, further lowering the moisture content of the sludge, while the CFP removes the tertiary water from the remaining solid particles by pressing the particles into a solid cake.

A GRID AND A VAT FOR A FILTRATE VAT ASSEMBLY OF A VERTICAL FILTER PRESS

A grid and a vat for a vat assembly of a vertical filter press such as a tower press is disclosed. The grid is provided with a topographical pattern engaging with a corresponding, inverse topographical pattern on the filtrate vat. The topographical patterns guide the filtrate flow towards a filtrate outlet and reduces the formation of vortices and turbulent flow of the filtrate, hence increasing the filtrate flow rate through the vat. Simultaneous, the topographical patterns improve secure attachment of the grid onto the vat, thereby allowing increased travel speed of the filter medium during advancement thereof. As a result, the cycle time of a filtration process may be reduced, and consequently, the overall capacity of the associated filter press is increased. A filtrate vat assembly and a vertical filter are also disclosed.

A filter press is disclosed for separating solid components from liquid components of a slurry. The filter press includes side beams and a plurality of filter plates oriented at right angles to the longitudinal direction of the side beams. The filter plates are adapted to move along the side beams. A stationary end is arranged on one end of the side beams and a movable head is adapted to transport the filter plates along the side beams. The filter press includes a press system adapted to exert a closing pressure on the filter plates to press the filter plates against each other. The press system further includes at least one electrically driven actuator adapted to generate an axially directed force on the filter plates by the movable head. The disclosure also relates to a method for separating the solid components from the liquid components of a slurry.

Disclosed is a dynamic separation and filtration system for dewatering and dehydrating of slurries and sludges. The system includes a compression filter press cylinder in which hydraulic pressure within a sealed liner is used to press and separate moisture from a sludge. A self-contained closed sealed liner pressurizing component is connected thereto, for supplying pressurized hydraulic fluid to the sealed liner, and a compressed air and vacuum and backflushing cylinder component is connected thereto for voiding the press cylinder of a resulting cake. A sludge transfer and metering component supplies metered quantities of sludge to the press cylinder. A dynamic filtration clarifier and thickener initially separates solids from a slurry and thickens the slurry into sludge that is supplied to the metering component.
