摘要： A charging system for charging a reactor with air used energy produced by the reactor and includes a vessel having a hollow interior cavity partially filled with a liquid slug, a first air pocket within the cavity on a first side of the liquid slug, and a second air pocket within the cavity on a second side of the liquid slug. The liquid slug forms a water trap seal in the cavity between the two pockets and moves within the vessel in a cycle in which gas is loaded into the first air pocket in a first stroke and gas in the first air pocket is compressed in a second stroke. Movement of the liquid slug during the second stroke is caused by an increasing pressure in the second air pocket due to introduction of high-pressure gas from the reactor into the second air pocket.

摘要： The disclosure relates to enhancing alkalinity of brine, e.g. seawater, using bipolar membrane electrodialysis (BPMED) without removing divalent cations that otherwise cause scaling. In one embodiment, a BPMED is employed wherein the brine volumetric flow rate through a basification compartment is greater at a given current density than that through a brine compartment which increases the pH of the brine output while keeping it below the precipitation pH. In one embodiment, the spacer located in the basification compartment is thicker than spacers elsewhere in the BPMED so as resist membrane distortion due to the increased hydrostatic pressure in the basification compartment given the greater volumetric flow. The brine output having increased alkalinity can be returned to the ocean to mitigate acidification and enable capture of atmospheric carbon dioxide.

摘要： In a water treatment system, a pretreatment chemical is added to water stream in a pretreatment process including a coagulation, flocculation and separation to reduce amount of dissolved and/or particulate matter in the water stream. Hydrophobic conditions in the water stream are monitored upstream or downstream from adding the pretreatment chemicals. Dosing of the pretreatment chemical to the water stream is controlled based on the monitored hydrophobic conditions. Thereby a membrane fouling in subsequent membrane filtration stage can be minimized.

摘要： Taught herein is a two stage process for removing dissolved and emulsified oil from produced water (PW) from, for example, a hydrocarbon well. The first stage involves microbiological stimulation of indigenous oil degrading methanogenic microbial communities that are adapted to high salinity conditions preferably by supplying carbon dioxide and protein-rich matter (isolated soy protein) under controlled pH conditions. The second stage removes toxic metals using filters made of compressed powdered dolomite of uniform grain size. Increased levels of toxic metals removal are achieved by filtrating PW previously treated for oil. To further increase the removal efficiency of the dolomite filter, calcium and magnesium is removed from PW by the addition of lime and soda ash in a sedimentation tank, and guar gum is supplied to PW to enable the trapping of toxic metals by guar gum in small pore throats of the dolomite filter.

摘要： A method includes: (1) using a chelating agent, extracting divalent ions from a brine solution as complexes of the chelating agent and the divalent ions; (2) using a weak acid, regenerating the chelating agent and producing a divalent ion salt solution; and (3) introducing carbon dioxide to the divalent ion salt solution to induce precipitation of the divalent ions as a carbonate salt. Another method includes: (1) combining water with carbon dioxide to produce a carbon dioxide solution; (2) introducing an ion exchanger to the carbon dioxide solution to induce exchange of alkali metal cations included in the ion exchanger with protons included in the carbon dioxide solution and to produce a bicarbonate salt solution of the alkali metal cations; and (3) introducing a brine solution to the bicarbonate salt solution to induce precipitation of divalent ions from the brine solution as a carbonate salt.
