  • Heat recovery from wastewater

    Heat recovery from gray water is particularly important in water-intensive industries such as pulp and paper plants, dairies and breweries. Rather than flushing used water down the drain, consider whether a heat exchanging system can help you put that energy to work in your process again. Most plant operators arc aware of the need to save money and reduce the environmental impact of their plant ...

  • Paper and Cardboard - Recovery or Disposal?

    To provide a solid basis for policies and policymakingin the field of waste management, the environmental and economic impacts causedby different waste treatment options should be examined. In recent years, a large number of studies comparing recycling with recovery or final disposal have been published, which are based on life cycle assessment (LCA) and cost-benefit analysis (CBA). To the ...

  • A model and a simulator for disaster recovery

    The level of economic and social cost arising from large scale disasters has become apparent in recent years. One of the conclusions that can be drawn from recent experiences is that both corporations and regulators have difficulty in predicting both the post disaster scenario, and the results of management actions in these scenarios. This paper discusses an approach that could lead to ...

  • A Bayesian decision support system for vehicle component recovery

    This paper presents a decision support system (DSS) whose core is based on Bayes' networks and influence diagrams that helps remanufacturers to choose the best product recovery option on the basis of the information provided by emerging technologies such as RFID tags and sensor networks. Such technologies can have significant impact on the effectiveness with which product information is generated ...

  • Planning for disaster recovery

    Q: When is a business disaster not a complete disaster? A: When you have a disaster recovery system in place, of course. The dictionary defines disaster as “an occurrence that causes great distress or destruction”. Any business can be affected by natural disasters, like recent weather patterns, contrived disasters such as the credit crunch, or even physical disasters like the loss of your ...

  • The risky business of resource recovery

    Waste management operations, like any transport business, have many risks attached to them and all operators should avoid the “Dodgy Brothers” ignore-the-risks to save costs approach! Any transport business with large vehicles working in tight city and site access areas is prone to accidents and near miss incidents. Add to that the hazards of working with lifting, loading and compacting systems. ...

  • Gold Recovery-1

    The manufacturing of jewelry is comprised of molding to form the jewelry followed by a polishing step, then deburring or ultrasonic cleaning. These steps leave residual gold in the rinsing and ultrasonic cleaning waters. To recover the gold, industries use the FloccinAgentstm for a one step liquid/solid separation process. The process is to collect all of the wastewater into a mixing container. ...

  • Environmental evaluation of systems for the recovery of biogenic wastes

    The recovery of waste materials is promoted by the German Waste Act 'Kreislaufwirtschafts- und Abfallgesetz'. It requires that among the recovery routes available for a specific waste category the priority has to be on those which are more environmentally compatible. As a restriction given by the law, only those recovery routes which are technically feasible and economically reasonable must be ...

  • Case study: OCC recovery

    Challenge A waste recycling facility was looking to recover mainly OCC (Old Corrugated Cardboard) from his waste stream. They saw the value in recovering this product, but were presently manually sorting the material off of the floor on a daily basis. Even with floor sorting, the customer was able to recover in the neighborhood of 10-12 bales per day. Approach ...

  • H2S Oxidation and Sulfur Recovery

    Lubrizol’s facility in LeHarve, France produces a lube oil additive via a batch reaction that uses elemental sulfur as a reactant and produces H2S as a byproduct. Lubrizol selected Gas Technology Products LO-CAT® II Hydrogen Sulfide Oxidation Process to sweeten H2S emissions and recover sulfur. The LO-CAT II system was chosen for its ability to handle the process variation in H2S ...

  • Optimization of a Sulfur Recovery Unit

    Prior to Suncor’s purchase of the Spirit River facility, little attention was given to the LO-CAT unit. In general, over injecting chemicals into a LO-CAT unit will not result in operating problems, just higher than required operating costs. Consequently, in remote gas plants such as Spirit River, it is sometimes difficult to convince operators to change operating conditions if the unit is not ...

  • Recovery of ammonium from digestate as fertilizer

    Ammonia inhibition can be a major problem during anaerobic digestion of manure and municipal and industrial sludges. Anaerobic digestion is sensitive to higher NH3-N concentrations, which are inhibiting and at certain levels even toxic for methanogen bacteria. The Nijhuis Ammonium Recovery (AECO-NAR) system can solve this problem and removes ammonium from digestate or other substrate for ...

  • Oil recovery reduces sewer cleaning

    Doskocil Food Service Company, a division of Foodbrands America, Hutchinson, Kan., produces 2 million pounds of pizza toppings a week. After cooking, the meat toppings are flash-frozen in one of two spiral freezers. Air currents within the freezer carry grease-containing vapors through the ammonia freezer coils, where they adhere and become lodged. Doskocil uses 1,600 gallons of water per hour to ...
