    摘要: In a multistage osmosis treatment method including: subjecting liquid to reverse osmosis treatment in a first-stage reverse osmosis separation module (31); adding an alkali agent to the obtained permeated water (5) to adjust a pH value of the permeated water (5) in an alkaline region; and further subjecting the permeated water (5) to reverse osmosis treatment in second and subsequent stage reverse osmosis separation modules (32), the supply water (5) to the second-stage reverse osmosis separation module (32) is subjected to at least one treatment selected from deferrization, demanganization, decarboxylation, and addition of a chelator and a scale inhibitor. Because of this, multistage reverse osmosis treatment is provided, in which the separation performance of the second and subsequent stage reverse osmosis membrane modules is enhanced, and liquid can be separated and purified to a high degree, and boron and the like that are not dissociated in a neutral region can be separated at a high blocking ratio.

    摘要: A liquid dispensing apparatus and method ensure that a liquid dispensed contains a specified level of a first solute. A solution is formed by dissolving a solid in the liquid. There is an inlet for the liquid and an outlet for dispensing the liquid. A mixing chamber is provided for a concentrated solution of the second solute. A metering device meters the concentrated solution from the chamber into another body of the liquid upstream of the outlet to form the liquid containing the specified level of the first solute. A member in the chamber receives the solid. There is a regulator for regulating output of the liquid from the apparatus. An actuator operatively connects the member the regulator. Solid on the member opens the regulator to allow the liquid to be dispensed from the apparatus. When the solid is depleted, the regulator is closed to prevent the liquid from being dispensed.

    摘要: A method for regenerating a used halide fluid comprising a density greater than 9.0 lbs/gal. and containing both soluble and insoluble impurities. This method comprises the steps of (1) adding acid to the used halide fluid so that the pH is within a range of approximately 0 to 10.0; (2) contacting the used halide fluid with halogen to increase the density to at least 10.0 lbs./gal., adjust the desired true crystallization temperature of the fluid and oxidize soluble impurities; (3) adding a reducing agent while maintaining the temperature at a minimum of 10null C.; (4) contacting the fluid with an alkali to neutralize excess acid; and (5) separating any suspended solid impurities from the fluid.

    摘要: A waste stream from energetics processing is treated using a pre-filter having media, preferably sand, and a metal that has a reducing potential, preferably elemental iron (Fe0). The pre-filter is connected to a zero-valent metal column reactor. The waste stream is pumped through the pre-filter to trap solids and deoxygenate it, then enters the reactor and is subjected to a reducing process. Most of the Fe0 is transformed to the ferrous ion (Fenull2), added to the resultant product, and fed to a continuous stirred tank reactor (CSTR) in which Fenton oxidation occurs. This product is then sent to a sedimentation tank and pH-neutralized using a strong base such as sodium hydroxide (NaOH). The aqueous portion is drawn off and the sludge pumped from the sedimentation tank. Both tanks are monitored and controlled to optimize required additives, while monitoring of pressure drop across the pre-filter and column reactor establishes replacement requirements.
