  • Titanium Scrap Metal Processing

    Background A world-class processor of titanium scrap had a wash system whose cleaning solution was becoming contaminated with both free floating unemulsified tramp oil and emulsified water soluble oil that was being washed off of titanium turnings. As the level of oil contamination increased over time in the wash solution, cleaning effectiveness diminished. The processor uses a metric, ...

  • Applicability of an electrochemical Fenton-type process to actual wastewater treatment

    The applicability of an electrochemical Fenton-type process (EF-HOCl-ReFe) to the treatment of three actual wastewaters, namely wastewater from an automobile factory (automobile wastewater), metal scrap-cleansing wastewater, and municipal wastewater, is discussed in this research. The EF-HOCl-ReFe successfully removed the chemical oxygen demand (COD) from automobile wastewater pre-treated by a ...

  • Treatment of diazo dye C.I. Reactive Black 5 in aqueous solution by combined process of interior microelectrolysis and ozonation

    Interior microelectrolysis (IM) as a pretreatment process was effective to treat Reactive Black 5 (RB5) in this study. The removal rates of chemical oxygen demand (COD), total organic carbon (TOC) and color were 46.05, 39.99 and 98.77%, respectively, when this process was conducted under the following optimal conditions: the volumetric ratio between iron scraps and active carbon (AC) ...

  • Recovery of Precious Metal Catalysts - A New Process Using Supercritical Water Oxidation

    Up to now, the recovery of precious metals used as catalysts in chemical processes has involved the use of incineration. Now, however, a British-Swedish joint venture has developed a process which uses supercritical water oxidation instead, which provides many economic and environmental advantages. Precious metals are used extensively in catalysts in a wide range of industrial chemical processes. ...

  • Significant increase in the value of aluminium swarf thanks to briquetting process - Case Study

    The GLEICH group increases its profitability by compressing 3,800 tonnes of swarf each year Should you just send the metal swarf created during manufacturing to the scrap dealer or should you increase its value by selling it for profit? The GLEICH group discovered the answer to this around ten years ago. Since then, the family-run business has been turning its aluminium swarf into ...

  • Staged Thermal Treatment Combined With Pyrometallurgical Smelting Producing Energy and Products From Waste

    Incineration of waste is considered as a state-of-the-art technology. However staged gasification in combination with pyrometallurgical smelting is ready for market introduction and offers principal advantages. These are higher efficiency (up to 35% electricity), efficient and cheaper fuel gas cleaning (less emissions), high quality secondary products (synthetic basalt), high input flexibility, ...


  • Analysis of monitoring results of the separation and greywater treatment system at Chester Woods Park, Olmsted County, Minn.

    Introduction In 1993, Olmsted County installed an advanced individual sewage treatment system (ISTS) at the caretaker's residence at a County-owned park to demonstrate waste load reduction and downsizing of drainfield area. The subject system has two components--1) a composting/vermiculture blackwater system and a 2) aerobic graywater treatment system. The separation of the high strength ...
