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.

An ion exchange device main body 3 includes: a tubular body 31 into which an ion exchange resin bag 5 accommodating the ion exchange resin is inserted through an opening and which has a liquid outlet 312 in which a liquid outlet port 314 for discharging an ion exchange target liquid to outside is formed; a lid 32 that is supported by the tubular body 31 and has a gas injection portion 324 in which a gas injection port 325 for injecting a to an inside 311 of the tubular body 31 is formed; a lead-out pipe 42 that is connected to the liquid outlet 312 and guides the ion exchange target liquid to the outside; and a check valve 44 that is provided in the lead-out pipe 42 and prevents the ion exchange target liquid from flowing backward from the outside to the inside.

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.
