Development of a process for waste eggshell valorisation
Ribeiro, André; Graça, Jessica; Castro, F.; Vilarinho, Cândida; Carvalho, JoanaIn this work it was evaluated the adsorption efficiency of calcined eggshell from the egg-breaking operations in the treatment of wastewaters from different industrial units. It was evaluated the removal of organic material, expressed as chemically oxygen demand (COD), in leachate wastewaters from sanitary landfill (LLWW) and the municipal residual wastewaters (NWW). It was also assessed the efficiency of alkal...
Adsorption process onto an innovative eggshell-derived low-cost adsorbent in si...
Carvalho, Joana; Ribeiro, André; Graça, Jessica; Araújo, Jorge; Vilarinho, Cândida; Castro, F.ISBN 978-989-97429-1-8 ; As the current global trend towards more stringent environmental standards, technical applicability and cost-effectiveness became key factors in the selection of adsorbents for water and wastewater treatment. Adsorption is by far the most versatile and widely used method for the removal of pollutants due to its high removal capacity and ease of operation at large scale. Recently, vario...
