Abstract: The present description relates to a method and a system for generating a Fenton reagent. Particularly, the description relates to a method and a system for oxidizing contaminants from wastewater. The Fenton reagent can react with various organic compounds and metallic elements. The method of producing an in-situ Fenton reagent comprises: providing an aqueous solution comprising at least one contaminant; providing at least one column comprising i) an inlet and an outlet separated by a flow chamber, and ii) a mass of iron fibre in the flow chamber between the inlet and the outlet; providing at least one dispenser retaining a hydrogen peroxide generating solid and permitting passage of the aqueous solution through the dispenser; optionally acidifying the solution upstream of the at least one column, and passing the aqueous solution through the at least one column.

Abstract: The present invention relates to method and a system of reducing chromium (VI) from a chromium bearing solution. The reduction of the chromium (VI) is achieved by contacting the chromium bearing solution which comprises chromium (VI) ions in an aqueous solution with iron fibers in an exchange mass under oxidation-reduction potential conditions at a pH of at least 2.5, with entry of iron ions into solution in the aqueous solution and reduction of the chromium (VI) ions to chromium (III) recovered in the exchange mass. A solution substantially free of chromium (VI) ions and total chromium is produced and discharged from the exchange mass.

Abstract: A method and apparatus for measurement and control of parameters are described. The method comprises the steps of: taking a sample from each of a plurality of samplings points in a controlled sequence, the sample having a sample volume; transferring the sample volume to an instrument measurement cell according to the controlled sequence the instrument measurement cell comprising at least one instrument, and a casing having a cell volume, wherein the at least one instrument measures a value of at least one process parameter of the sample volume, and logging and/or transmitting the value of the at least one process parameter of the sample volume. The apparatus comprises: a plurality of fluid transporters, an instrument measurement cell comprising a casing having a cell volume; and at least one instrument within the casing; a manifold fluidly connected between the plurality of fluid transporters and the instrument measurement cell, and an apparatus controller.

Abstract: Spent color photography liquids comprising alkaline developer liquid and fixer liquid loaded with iron ions generate a dischargeable effluent, in which clogging of drains and conduits with precipitated iron oxides is minimized or avoided; the liquids are fed through separate feed ports into a vessel to form a liquid bath, the feed ports being isolated from each other and from the liquid bath; liquid effluent is pumped from the bath to form an effluent flow; preferably the pumping employs a suction generated by flow of a carrier liquid such as water through a venturi passage, whereby the liquid effluent is entrained in the flowing water and discharged under pressure, the precipitated iron oxides being retained in a dispersed non-clogging state.

Abstract: Value metal, for example, silver in a spent silver bearing photographic solution is efficiently recovered in an exchange mass comprising a particulate inert substrate, for example, cellulosic fibers, synthetic fibers or sponge particles, co-mingled and interlocking with elongate particles of replacement metal, for example, strands of steel wool; the substrate defines a non-channeling random flow paths for liquid flow, and inhibits carriage of recovered value metal by the flowing liquid.

Abstract: A neutral dischargeable effluent is developed by reaction between an acidic, spent photographic fixer liquid and an alkaline, spent photographic developer liquid; the spent fixer liquid contains iron in solution, the iron being introduced in a de-silvering pretreatment of the spent fixer liquid. The two liquids are fed into a treatment chamber and are allowed to react in the treatment chamber to form a neutral liquid and precipitated iron-containing solids; the solids settle in the treatment chamber and the neutral liquid rises upwardly through a synthetic organic polymer fiber filter pad into a discharge chamber above the filter pad; fine sticky particles suspended in the rising neutral liquid are retained by the filter pad; a neutral effluent is discharged from the discharge chamber.
