  Composition and Contaminant Loads of Residual Household Waste Part III: Physico-Chemical Properties and Contaminant Concentrations

  Abstract. Physico-chemical properties of residual waste are key factors for disposal standards. Reliable input data for treatment plants (MSWI) need to consider the heterogeneity and variability of waste composition. This requires thoroughly designed sampling schemes, a consistent separation of bulk waste into uniform fractions, and adequate methods for sample preparation and analysis. The ...

  Construction materials production. Application of the ABC-100 unit

  Expanded clay industry In the process of expanded clay production the argillous raw material homogenizes and mills in the drilling mud mixers and rollers. But these equipments not ensure qualitative desintegration. As result we obtain the expanded clay of low quality. Insufficiently desintegration and homogenizing of raw materials lead to the result when even 3% of carbonate ...
