Device for drawing off clear water from below a water surface, especially for a sewage treatment plant or for emptying storage basins, comprising the following components: - A pump is held in a container, which has a suction opening and a pressure outlet connected to an outlet line, - the outlet pipe leads out of the container, - the container has a particularly lower inlet opening, which can be temporarily closed by a valve, - the container is preferably a floating container.

A neutralization / water separation tank for an esterified product including: a neutralization part in which a crude product mixture containing alcohol and an ester compound, a neutralizing agent, and water are put to produce a neutralized mixture; a water separation part which divides the neutralized mixture into a floating layer and an aqueous layer; a first partition wall which extends upward from a bottom surface to provide an upper passage and by which the neutralization part and the water separation part are partitioned; and a second partition wall which extends downward from a ceiling to provide a lower passage, wherein the water separation part includes: a first water separation part into which the neutralized mixture is introduced from the neutralization part through the upper passage; and a second water separation part into which the neutralized mixture is introduced from the first water separation part through the lower passage, wherein the first water separation part and the second water separation part are partitioned by the second partition wall.

The present invention relates to the field of dihydromyricetin extraction and purification, and in particular to a dihydromyricetin extraction and purification process. Technical problem: the dihydromyricetin extraction and purification process aims to resolve the technical problems of increased cost of subsequent impurity removing and safety risks in high-temperature centrifugation in the prior art. Technical solution: a dihydromyricetin extraction and purification process: step 1: weighing a raw material, adding an extraction solvent in an amount 5 times that of the raw material to perform reflux extraction, concentrating the filtrate to an extract, and recovering acetone; step 2: resting for crystallization for 24 hours; step 3: performing suction filtration to obtain light-green sediment underneath, and dry the sediment; step 4: adding 5%-10% activated carbon for decolorization and impurity removing; step 5: performing suction filtration; step 6: drying to obtain white powder of dihydromyricetin; and step 7: detecting a content with HPLC.

The present disclosure provides for devices, systems, and methods of separating PFAS compounds from wastewater leachate. After separation, the PFAS compounds can be rendered less harmful. The present disclosure provides for devices, systems, and methods that uses aeration-induced foaming to isolate PFAS from landfill leachate into a concentrated, volume reduced liquid (coalesced foam), which can be separated and treated.

An esterification product neutralization / water separation apparatus according to an embodiment of the present invention for solving the above problems includes: a neutralization tank into which an unrefined product mixture containing an alcohol and an ester compound, a neutralizing agent, and water are introduced to form a neutralized mixture; a water separation tank disposed below the neutralization tank and separating the neutralized mixture into a floating layer and an aqueous layer; a partition wall extending downward from the ceiling of the water separation tank to form a lower passage in the water separation tank; and a transfer line for transferring the neutralized mixture from the neutralization tank to the water separation tank, wherein the water separation tank includes a first water separation section into which the neutralized mixture flows from the neutralization tank via the transfer line; and a second water separation section into which the neutralized mixture flows from the first water separation section via the lower passage, and the first and second water separation sections are separated by the partition wall.

A two-step process for recovering useable solids from food processing wastewater and for significantly reducing the pollutants, chemical, bacterial, and viral load. The first step is the addition of pretreatment chemicals such as metal-based coagulant, pH adjuster, oxidant or a combination thereof. The second step is pumping the chemically pretreated wastewater into a foam fractionation system where a gas is introduced into the chemically treated wastewater to create a rising foam that captures and remove solid materials from the remaining wastewater effluent. The solids are recovered for additional post-processing and the effluent is discharged for post-processing or to existing bodies of water.
