摘要:
The invention relates to a system and method for water treatment. The system includes a flotator (1) chamber, a set of filtration membranes (2), a water source (3) for filtration, a micro-nano-bubbles (4) generator, a pump (5) for washing membranes, a filtrate tank (6), a filtrate (7) pump, sludge scraper (8), sludge tank (9). The flotation (1) chamber is connected via a pipeline (10) with a micro-nano-bubbles (4) generator, to which a pipeline (11) is connected and directed to a set of filtration membranes (2); and at least one of the pipelines (10) (11) is equipped with a pump (12). The method is based on the fact that water through the pipeline being the water source (3) is pumped into the flotator (1) chamber and then, via a pipeline (10), it is pumped to a micro-nano-bubbles (4) generator, where it is saturated with micro-nano-bubbles with a diameter of 1 to 50 micrometres and then through a pipeline (11) is pumped to a set of filtration membranes (2).
摘要:
A fixed or mobile water treatment system comprises a primary screening tank that filters wastewater to remove inorganic and organic pollutants from the wastewater, and includes an electro-coagulation unit that provides an electrical charge to wastewater exiting the primary screening tank, ultraviolet light and oxidation processes in one or more settling tanks that remove pollutants from the wastewater, and one or more filters that remove pollutants from the wastewater.
摘要:
A method of chemical extraction from an aqueous solution includes receiving an aqueous solution including dissolved inorganic carbon. The method also includes increasing a pH of a first portion of the aqueous solution to form a basic solution. The basic solution is then combined with a second portion of the aqueous solution to precipitate calcium salts. The calcium salts are then collected.
摘要:
A method of making building materials from an aqueous solution includes receiving the aqueous solution with dissolved ions and increasing a pH of the aqueous solution so the dissolved ions precipitate from the aqueous solution as salt. The method also includes collecting the salt precipitated from the aqueous solution and forming the building materials from the salt.

The present invention relates to a process for the preparation of an aqueous solution comprising at least one earth alkali hydrogen carbonate, a process for the mineralization and/or stabilization of water as well as the use of the aqueous solution 5comprising at least one earth alkali hydrogen carbonate obtained by the process for the mineralization and/or stabilization of water.
摘要:
A filtration system suitable for recovering base stock from used lubricating oil and other applications passes feedstock over nano-filtration membranes in a serpentine flow. Pressure boosters installed in the openings separating consecutive stacks serve to restore lost pressure of the feedstock. As pretreatment a "knocking" non-blinding filter separates particulates from a feedstock by a knocking action that dislodges particulate matter which has come to rest on the screen. Further pretreatment includes a vacuum evaporator for flash evaporation of volatile components from a liquid and effecting the extraction of water and glycol from used engine lubricating oil. The liquid is heated or cooled when flowing over some of the surfaces to adjust for heat lost or acquired during exposure of the liquid surface to a gas or vacuum. Liquid moves on the surface of the discs under centrifugal force or a wiper blade guides the liquid as it moves over the support surface.
摘要:
A system and process for removing divalent ions from a MEG feed stream (15) is presented. The system includes a chemical treatment tank (25) where chemicals are mixed with the feed stream (15) to form insoluble carbonate and hydroxide salts. The system also includes a membrane-type solid-liquid separation unit (60) that receives the feed stream (35) from the chemical treatment tank (25) and separates it into a filtrate (90) containing MEG and a retentate (130) containing the insoluble salts. The system may also include washing the retentate (130) to remove additional MEG, which is then recycled to a MEG regeneration or reclamation process. The system may also include a dryer (140) that receives waste slurry (132) from the solid-liquid separation unit (60) and dries it to form a solid waste, thereby facilitating its handling, storage, and disposal.
