  • Adsorption of ammonium using waste activated sludge from palm oil mill effluent treatment plant

    Low cost adsorbent was prepared using waste activated sludge (WAS) from a palm oil mill effluent (POME) treatment plant, and used to adsorb ammonium from aqueous solution. The effect of initial concentration, temperature, pH and adsorbent dose was studied in batch test to determine the kinetic and thermodynamic properties. The results showed that the uptake of ammonia increased with an increase ...

  • Adsorption of emulsified oil from spent metalworking fluid using agro-waste of Cajanus cajan

    Safe disposal of spent cutting fluids generated by the use of semi-synthetic fluids as coolant in material processing industries is a serious problem. The ultra-filtration method is mostly employed for the processing of spent cutting fluids. This method is costly and difficult to adopt by small and medium sized industries. In this study, efforts have been made to produce adsorbent using ...

  • Utilising waste activated sludge from a palm oil mill effluent treatment plant to remove methylene blue in continuous column studies

    The Waste Activated Sludge (WAS) discharged during the aerobic treatment of Palm Oil Mill Effluent (POME) was used to produce a low cost adsorbent for the removal of Methylene Blue (MB) from aqueous solution. This study employed a continuous process in a column packed with WAS as the adsorbent. The adsorption data fits Thomas and Yoon–Nelson model better compared to Adams–Bohart model under ...

  • Hydraulic Oil Spill on Roadway

    Fuel Oil Soaked Wood. Contact was made to our office in May/2007 regarding the wood base underneath an oil/kerosene furnace system which, upon removal, it was discovered that kerosene had leaked and was somewhat permeated, leaving an odor. With over-time saturation of the wood, we recommended multiple treatments. After use of our Terracap 3000/4000 kit, we received the following in a letter: "I ...

  • 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 ...

  • Treatment of salt affected soil in the oil field

    Soils, drill cuttings and other solid wastes which are exposed to high levels of salt through spillage from drilling and producing operations, pipe line breaks or leaks, become saturated with sodium. Although the EPA and the industry have demonstrated that the vast majority of such wastes are non-hazardous, in actuality, they have an adverse impact on the fertility of the soil. The degree of salt ...

  • Spilled heavy grade heating oil case study

    Heavy fuel oil escaped from a storage tank and entered the drainage system of a large creamery. This material passed to the aerated balance tank which precedes an activated sludge system treating the factory waste waters. Alerted to the spillage the operators were able to shut off the flow to the activated sludge system but not before a significant quantity of oil had passed through. Bio-Systems ...
