  • Recovering oil from grinding sludge - Case Study

    Zahnradfertigung Ott uses RUF briquetting unit A large volume of sludge is produced in the grinding of high-precision gears. In most cases, this grinding sludge is disposed of at high costs. Zahnradfertigung Ott, a specialist manufacturer of gears, found a better solution: since 2005, the company is using a briquetting unit from RUF to recover 500 litres of grinding oil per day from the ...

  • Changes of Cu, Zn, and Cd speciation in sewage sludge during composting

    The potential toxicity risks from heavy metals depend on their chemical speciation. The four stages of the Tessier sequential extraction method were employed to investigate changes in heavy metal speciation (Cu, Zn, and Cd) of sewage sludge during forced aeration composting, and then to identify whether the composting process would reduce or enhance their toxicities. Throughout the composting ...

  • Floccin for Metals Removal Beats Hydroxide Precipitation Hands Down

    The traditional approach for metals removal is Hydroxide Precipitation where the solubility for the metals changes to insoluble (precipitation) in the form of a metal Hydroxide as the pH increases. The common pH range for this is between 10-11 pH depending on the metal. Lime (calcium hydroxide or CAOH2), caustic (sodium hydroxide or NAOH) or magnesium hydroxide (MgOH2) are generally the chemicals ...

  • Solidification / Immobilisation of sludge from physical-chemical WWT process

    In 2003 econ received an inquiry from a service company operating an industrial waste water treatment plant. At the end of the physical-chemical WWT process this client generated metal-hydroxide sludge from his chamber filter presses. Originally he discharged the sludge into skips and brought it to a hazardous waste landfill. At this landfill, a solidification process was used to stabilise ...

  • Sludge suspension from numerous differing steel industry residues

    econ have been active for many years as a supplier of mixing units for the metal and steel industry. One of our long term clients requested that econ quote a system to produce a highly viscous suspension from nu-merous differing residues. The aim was to use this suspension as a protective layer inside the transport ves-sels of the hot, molten slag. Thus, a number of differing technical ...

  • Wastewater from metal finishing industry set for more regulation from the Environmental Protection Agency

    The U.S. Environmental Protection Agency (EPA) recently released its preliminary 2014 Effluent (liquid waste or sewage discharged into a river or sea) Guidelines Program, which outlined more regulations for wastewater from those within the metal finishing industry. A filter press has been a long-trusted solution for treating metal waste, even for those applications that are difficult to dewater. ...

  • Case Study: Heavy Industrial Laundry

    This facility washes heavily soiled towels from the ink printer and furniture polishing industries. The wastewater generated is very concentrated with metals and hydrocarbons making it difficult to treat in their DAF pretreatment system. The facility was using conventional chemistry with sulfuric acid, organic/inorganic coagulant, metal precipitant,flocculant, and Harborlite (filter press ...

  • Lead Plating

    A Midwest company is plating lead and etching the material with an HCl batch. The resultant wastewater had a lead concentration of 2,000-4,000 ppm. Traditional chemistry (pH adjustment to 9.8, coagulation/flocculation) could only decrease the concentration to 5.0 ppm. The facility was had to retreat the wastewater and only then could reach a lead level of 3.0 ppm.  With the use of the ...
