The aim of this work is to study the characteristics of three types of WWTP residual sludge (urban and industrial) in order to be used as solid fuels. The tests focused on the physico-chemical characterization of each type of sludge (water content, organic matter, fuel fraction, ash), the assessment of their energy content (calorific value HHV, effect of moisture content on HHV) and the heavy metal content. The effect of adding lime to the sludge samples on different parameters (moisture and heating value) is also investigated. Source

The use of alternative fuels has become increasingly widespread. They are basically designed based on industrial waste so that they can substitute fossil fuels which start to become scarce. Alternative fuels must meet some criteria, namely an important calorific content, minimum humidity and ash content. When it comes to combustion, the most interesting parameter is the calorific value which represents the thermal energy released during combustion. The experiments that were conducted showed that the calorific value is influenced by other parameters namely moisture and ash content. It was therefore necessary to study the behavior of the heating value in terms of these two parameters in order to establish a relationship that is used to describe the behavior. This is expected to allow a simulation of the calorific value of a mixture of various industrial waste. © Owned by the authors, published by EDP Sciences, 2013. Source

304 Stainless Steel, commonly used in dentistry, undergoes significant corrosion in a saliva medium. The present work studies the influence of a commercial mouthwash, Eludril, on this corrosion. Electrochemical voltammetry and impedance measurements were carried out on 304 stainless steel dental wire in artificial saliva medium (Ringer's solution) to which the mouthwash is added. These measurements, completed by scanning electron microscopy (SEM), clearly show a localized corrosion of dental wire. Source
