The present invention relates to a method for extracting circulating nucleic acids from a biological fluid. The method comprising the successive steps of providing the biological fluid supposed to contain the circulating nucleic acids. Then the biological fluid is contacted with a lysis solution comprising at least a chaotropic agent, a binding solution comprising at least a PEG derivative designed for cooperating with at least part of the circulating nucleic acids, wherein the binding solution is free of ethanol and isopropanol, and a solid support capable of capturing at least part of the circulating nucleic acid. Finally, the solid support is separated from the lysis solution, from the binding solution and from the biological fluid.

A composite filter aid may include at least one mineral associated with an antimicrobial metal compound, wherein the filter aid has a permeability ranging from 0.1 to 20 darcys. The antimicrobial metal compound can be chemically deposited on the mineral surface or bonded to mineral structure by binder or high temperature calcination.

In one aspect, a functionalized porous material includes a synthetic porous material, the synthetic porous material comprising a surface, wherein at least a portion of the synthetic porous material surface is a substrate; and a mixed-metal hydroxide, wherein the mixed-metal hydroxide is affixed to the substrate.

A chloride salt eliminator system and method for removal of chloride salt from glycol circulated through a reboiler in natural gas dehydration, in a continuous process, close to the wellhead. Hot glycol from the reboiler is pumped into a salt eliminator unit having independently replaceable filter elements which trap chloride salts which are not soluble in hot glycol and pass clean glycol for return to the reboiler.

A method of filtering a main fluid using a rotary fluid filter. A 360 degree filtration cycle is initiated by receiving, at an initial position, a first portion of a main fluid at a front end of a first fluid flow passage extending through a filter body rotationally mounted within a housing. The filter body is rotated in a rotation direction and the first portion of the main fluid is discharged from a rear end of the first fluid flow passage, having passed through a filter received in the first fluid flow passage. The filter body is rotated further in the rotation direction and a first portion of a backwash fluid is received through the first fluid flow passage from the rear end to the front end. The rotational cycle is completed by rotating the filter body back to the initial position.

A filter includes a filter media material through which a gas is transportable, a first metal salt immobilized upon the filter media material and a second metal salt immobilized upon the filter media material, wherein the first metal salt and the second metal salt are immobilized upon the filter media material from an aqueous solution comprising the first metal salt and the second metal salt.
