Provided is a system and method for extracting organic solutes from water with a filter media. The system and method allow for regenerating the filter media following treatment of a water supply containing one or more organic solutes to allow the media to be reused for subsequent water treatment operations. The system and method also allows for regeneration of the displacement fluid for reuse in the regeneration of the media with recovery of at least one or more organic solutes from the displacement fluid. Additionally, the system and method allows for substantially continuous treatment of a water supply and regeneration of a filter media.

Method for treating water to reduce the dissolved silica content thereof, the method being characterised in that it comprises at least one step of adsorbing the dissolved silica, the step consisting in passing the water through a reactor housing an adsorbent granular material consisting of grains of iron hydroxide (III) and/or iron oxyhydroxide (III) and at least one step of regenerating the adsorbing power of the granular material, the step consisting in bringing the granular material into contact with a base and at least one chloride.

The present invention relates to a lectin-macromolecular carrier coupling complex for separating glycosylated exosomes from a clinical sample, which comprises a macromolecular carrier and lectins coupled to the outer side of the macromolecular carrier. The complex may simply, conveniently, rapidly, and accurately separate glycosylated exosomes from a clinical sample with a high separation efficiency and a good repeatability; and the separated exosomes are intact in morphology without rupturing or cracking, may be directly used for liquid detection of glycosylated exosomes, or directly used for immunology-related detection, or directly used for gene detection or analysis after extracting related nucleic acids from the exosomes.

The present invention relates to the use of alkali hydroxide for the regeneration of apheresis columns for the affinity chromatographic removal of CRP and a method for the simplified regeneration of apheresis columns for the affinity chromatographic removal of CRP with the use of an alkali hydroxide solution and apheresis devices which are designed in such a manner as to be resistant to alkali hydroxide solutions and to allow the regeneration of apheresis columns for the affinity chromatographic removal of CRP in continuous operation.

The present invention provides a liquid-absorbing raw material processing system and its operation method. The liquid-absorbing raw material processing system is composed of a cutting module, a bulk pulping module, a salt slurry processing module, and a liquid-absorbing raw material manufacturing module, which are connected in series. The operating method of the liquid-absorbing raw material processing system is to process absorptive articles such as diapers or sanitary napkins, etc., which are retained and made into fluff liquid-absorbing raw materials through the purification and separation steps performed by the modules of the liquid-absorbing raw material processing system.

The invention relates to devices, systems, and methods for precision recharging of sorbent materials in a sorbent module. The devices, systems, and methods use manufacturing characteristics of the sorbent module to set recharge parameters used in recharging the sorbent material.

Magnetic nanoparticle coated porous materials for recovering a contaminant from contaminated water are provided. In embodiments, such a material comprises a porous substrate having a solid matrix defining a plurality of pores distributed through the solid matrix and further comprising a coating comprising magnetic nanoparticles on surfaces of the solid matrix.

A filter medium for removal of contaminants from wastewater. The filter medium includes a walnut shell particle having a metal hydro(oxide) nanoparticle bonded to the surface of the nut shell particle. The filter medium is particularly useful for treating produced water and wastewater generated in steam-assisted gravity drainage (SAGD) in recovery of hydrocarbons from oil sands to remove total organic carbon and silica. Processes for preparing the filter medium and for treating wastewater using the filter medium are also provided.

A method for reducing the concentration of amines in a wash liquid stream exiting a wash section in an acid gas scrubbing process includes introducing the wash liquid stream exiting the wash section of the acid gas scrubbing process to an adsorbent material, wherein the wash liquid stream has a first concentration of amines. The wash liquid stream having the first concentration of amines is flowed through the adsorbent material, and the adsorbent material retains at least a portion of the amines thereby providing a wash liquid stream having a second, reduced concentration of amines. The wash stream with reduced concentration of amines is recycled back to the wash section to remove amines more effectively from the acid gas being scrubbed. The adsorbent material can be regenerated for reuse. Amine recovered from the regenerated adsorbent material can be recycled to the process for reuse.
