  • Recovery and Distillation of Used Wash Solvent: Wattyl Australia

    It took Wattyl Australia just one year to recoup a $100,000 investment in a distillation unit that recovers solvent used in cleaning tanks and equipment in plants manufacturing solvent-based paints. It is now enjoying the ongoing savings as an addition to its bottom line. Instead of paying someone to dispose of the valuable solvents, the company is recovering 90% of the solvent and using it to ...


  • Solvent Recovery System Keeps Presses Rolling at World`s Largest Gravure Printing Plant

    When QUAD/GRAPHICS Inc. entered the publication gravure printing market, it followed the axiom of Daniel Burnham, the 19th century architect and urban planner, to 'make no small plans.' In 1985, the Pewaukee, Wis.-based printing company purchased two 96-inch web, eight-color, high-speed presses and installed them at its new printing plant in Lomira, Wis., near Milwaukee. Conventional wisdom at ...

  • Application of Membrane Technology for the Recovery and Reuse of Water

    Abstract As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...


  • Case study - Oxidizer energy recovery options

    Overview The mainstream media today is full of allusions to energy awareness and conservation. Just as visible these days are media references to astronomical dollar figures that can boggle the mind. This article does not seek to break out of that mold, but rather to conform to it – as Oxidizer Stack Heat Recovery offers a tremendous opportunity for both energy conservation and ...

  • Recovery of water and acid from leach solutions using direct contact membrane distillation

    This paper describes for the first time the use of direct contact membrane distillation (DCMD) for acid and water recovery from a real leach solution generated by a hydrometallurgical plant. The leach solutions considered contained H2SO4 or HCl. In all tests the temperature of the feed solution was kept at 60 °C. The test work showed that fluxes were within the range of ...

  • Case study - Maximizing heat recovery from your oxidizer and reducing operating costs

    More and more, companies operating air pollution control equipment today realize that the initial capital cost of an oxidizer system can be rapidly eclipsed by continued operating expenses if careful attention is not periodically given to the system. Below are ten tips to ensure your oxidizer is operating at peak performance. The first five tips focus on parameters end-users should know about ...

  • Power plants use oil skimmers to prevent contamination from spills

    Most hydroelectric plants designed in the 1960s were built with a station drainage sump that collects all drainage from the plant. As designed, float switches activate sump pumps that discharge liquids directly into the tailrace. The system cannot distinguish between types of liquids, so in the event of an oil leak, oil in the sump could be released into the tailrace. Modern ...

  • Nylosolv® Recycling

      In 1999, self-recovery of solvents was already common practice for the South-Hessian (German region) flexo-printing-plate manufacturer. At that time, management installed an OFRU solvent recovery plant of the type ASC-200, including a tank system for manual recovery of flexo-polymer solvent. This installation for continuous recovery was successfully used for approx. 15 years. Since then, ...

  • Comparison of a Regenerative Thermal Oxidizer to a Rotary Concentrator

    INTRODUCTION The regenerative thermal oxidizer (RTO) is a very durable, well-proven technology suitable for treating a wide variety of emission streams. However, The RTO may not be the most economical technology available. Two very common systems for treating emissions from coating and finishing processes are the RTO and the concentrator/ oxidizer system. To determine which system is best suited ...

  • CANSOLV® SULFUR DIOXIDE SCRUBBING SYSTEM

    The CANSOLV® System scrubbing technology is the leading regenerable SO2 scrubbing process. It uses an aqueous amine solvent in a conventional amine treater process flowsheet configuration to achieve high-efficiency removal of SO2 from a ...

  • Recovering Valuable Chemicals from Air Emissions

    Air emissions in many cases are a waste of valuable natural resources that should have become useful chemicals. In some cases the economic payback from recycling/reuse of air emissions can be almost as much a motivation to control air pollution as government regulations. Examples of recycling and reuse of air emissions are sulfur oxides emissions that can be made into sulfuric acid, cement ...


  • The search for water contamination can create hazards of its own

    It''s a paradox. Most of the very technologies being used today to test water for contaminants actually return more pollution to the environment than the tested water itself. Nevertheless, as we all know, water testing is crucial to our health. Modern industry has unleashed tens of thousands of chemicals into the environment. Many of these chemicals are essential, but it''s the control of them ...

  • Towards a desalination initiative using cogeneration with an advanced reactor type and uranium recovered from Moroccan phosphoric acid production

    Morocco is known to be among the first few countries to produce phosphate and phosphoric acid. Moroccan phosphate contains substantial amounts of uranium. This uranium can be recovered from the phosphate ore as a by-product during the production of phosphoric acid. Uranium extraction processes linked with phosphoric acid fabrication have been used industrially in some countries. This is done ...

  • How to Optimize Oxidation Systems for Efficient Operation

    Emphasis on air management within converting-process dryers and ovens is critical to the design of pollution-control systems for treating exhausts containing VOCs (volatile organic compounds). Efficient air management allows the pollution-control system to be optimally sized to meet the needs of the process. Good process control further defines the emission stream by avoiding the need for large ...

  • Put energy into emission control projects

    Many companies feel pressured to spend the least amount possible to meet environmental regulations, primarily because compliance isn’t a profit generating endeavor. What some environmental and compliance managers fail to realize is that emission control equipment can quickly become a profit decreasing endeavor with this penny wise-pound foolish approach. With mandatory greenhouse gas (GHG) ...

  • Treatment of high strength resin production wastewater case study

    Problem Full-scale Incineration of this wastewater had proved very expensive due to the fuel input required and the ongoing incinerator maintenance costs. The polymer manufacturer sought treatment alternatives to save money. Initial biotreatment pilot work indicated that biotreatment was not feasible using conventional activated sludge technology even when the concentrated wastewater was ...
