An automated waste water treatment system includes a collection tank constructed to hold waste water, a first flow line connected to the collection tank to output the waste water from the collection tank, an electrocoagulation unit that receives the waste water and outputs the waste water as coagulated waste water to a flow line, a polymer dosage tank to provide a polymer dosage into the flow line where the polymer dosage mixes with the coagulated waste water to produce and output flocculated waste water. A clarifier connected to the flow line receives the flocculated waste water and produces sludge-free waste water and concentrated sludge, a series of filters to output filter-treated water, and an ultrafiltration system that receives filter-treated water and outputs ultrafiltration-treated water to a reverse osmosis system.

The present invention is a CO.sub.2 based hydrometallurgical multistage reaction and separation system comprising: a pre-washing device configured to fully mix the feedstock, such as industrial solid waste, mineral and mine tailings with auxiliary reagents and water at specific ratio, a reactor configured to treat the washed slurry with CO.sub.2 bubbling and discharge the treated slurry to the next stage, multistage separators configured to separate solid particles from treated slurry and recycle the unreacted solids back into the pre-washing device, a by-product preparation device configured to generate calcium and magnesium based products from filtrate containing target elements, a water recirculating device configured to recycle the remaining liquor back to the system. The present invention ensures the whole system is able to continuously and consistently react at maximum capacity through continuous slurry feeding and CO.sub.2 bubbling into the reactors which also enables multistage circulating reaction.

A processing system for processing plant mixture into milk and pulp preferably includes a filter, a plunger mechanism, and a pulp catcher. The filter has a filter wall and floor that together define a chamber. The plunger mechanism (which has a plunger shaft with an actuator end and a plunger head end) is insertable into the chamber. A preferred plunger head at the plunger head end may have at least one clearing blade and/or a first part of a connector. The pulp catcher has a second part of a connector that may connect to the first part of the connector. The processing system may also include a filter lid and/or a ring funnel.

Disclosed are a method and a device for recovering uranium (U) using a process for chemically treating washing wastewater of a uranium hexafluoride (UF6) cylinder. The method and the device are provided to separate uranium (U) from the wastewater released during a process of washing the uranium hexafluoride (UF6) cylinder and to release a filtrate that satisfies atomic energy licensing standards and environmental regulation standards using evaporation and condensation. Accordingly, an independent technology and process for treating the wastewater released during the process of washing the uranium hexafluoride (UF6) cylinder are ensured, which provides easier maintenance and greatly reduces costs compared to the purchase and operation of apparatuses manufactured by foreign makers.

A press assembly and a method for producing plant-based milk may include coupling a tubular filter to a receptacle, the tubular filter having an open first end, a porous wall, and a closed second end. Plant-based raw materials are placed into the filter. The raw materials are pressed toward the closed second end of the filter using a standalone plunger having one or more wiper blades conforming to an inner periphery of the tubular filter, such that liquids of the raw materials pass through the porous wall of the tubular filter and into the receptacle. After the pressing operation, residual solids may be easily removed from inside the filter. This may be accomplished by removing a stopper from the bottom end, and expelling the solids by extending the one or more wiper blades through the opening.
