The invention discloses a reaction product separation device and a separation method. The reaction product separation device comprises a circulating tower, a pressure pump, a cooler, a water removal tank, a dehydration tower, a feeding pump and a product tower which are connected in sequence, the product tower is connected with the circulating tower; the circulating tower is also connected with the raw material water separation tank; by adopting an operation method of coupling decantation non-sharp separation rectification and variable pressure crushing azeotropy, the separation device can be used for continuously separating reaction products of a process for preparing methyl acrylate from methyl acetate-formaldehyde in industry, and is simple in process, small in equipment number, simple and convenient to operate and suitable for industrial large-scale separation.

The application discloses a method for recovering paracetamol, which comprises the following steps: dissolving substandard paracetamol particles in water, cooling, and removing most of starch-containing accessories in the particles; since the crystal particles of paracetamol product in the system are large and easy to precipitate, the paracetamol product can be obtained by fully utilizing the cooling and standing; the paste solution formed in the heating process of the starch accessories can be effectively separated by means of simple decantation; the first clear liquid can be continuously separated by decantation after standing to obtain the second solid paracetamol; and the solid particles of the two times are combined and refined. The recovery method is simple and easy to operate as a whole, does not need to use ethanol as a solvent, is low in cost, high in recovery rate, and can provide a reference for industrial-scale recovery of substandard paracetamol particles.

Fluid delivery system for providing a flow of microvesicle containing liquid to a subject, wherein the system comprises a first fluid conduit arranged to contain microvesicle containing liquid, wherein said first fluid conduit comprises an inlet arranged to receive microvesicle containing liquid at an input flow rate and an outlet arranged to provide microvesicle containing liquid at an output flow rate to said subject, wherein the system comprises a first pumping mechanism in fluid communication with the first fluid conduit arranged to induce a varying flow rate component in said first fluid conduit for at least partially preventing decantation of the microvesicles in the microvesicle containing liquid present in the first fluid conduit.

The present invention consists of a process for removing impurities from hard water. Using chemical agents, it removes impurities by mixing a chemical preparation and employing decantation in the first stage of impurity removal. Subsequent validation of the results allows for the removal of other types of impurities present in the water, such as arsenic, cadmium, cyanide, copper, chromium, mercury, nickel, lead, and zinc. Finally, it removes contaminants and microorganisms from the following group: fats and oils, suspended solids, organic carbon, total nitrogen, total phosphorus, worm eggs, E. coli, and fecal enterococci. The resulting sediments are used as biofertilizers, and the treated water can be discharged into conventional municipal sewer systems or, if necessary, treated with ozone (O3) for human consumption.
