    Abstract: The BAS (Biofilm Activated Sludge) process is comprised of MBBR (Moving Bed Biofilm Reactor) pre-treatment followed by conventional AS (activated sludge) which presents several advantages in comparison with conventional wastewaters technologies. In this study the BAS process is used for the treatment of wastewaters coming from a viscose and cellulose industry. Initially, the process is simulated using a wastewater process simulator BioWin under the three different scenarios and the experimental results are compared with the simulated results. Later on, the optimization of the process is carried out by the minimization of the operation cost since the nutrient dosage of N and P can be reduced until the COD percentage removal is affected. Finally, the introduction of urban waters together with the industrial wastewaters is studied to minimize the costs of the addition of chemicals nutrients.

    Abstract: The European Commission considers Construction and Demolition Waste (CDW) as a priority waste stream due to the large amounts generated. Cantabria is a northern Spanish region where new CDW legislation (BOC, 2010) has been developed and, as a consequence, a network of CDW distribution with recycling facilities and transfer stations needs to be properly located. This work deals with this objective by means of an optimization model that takes into account not only economical and environmental criteria but social aspects of the region as well. The proposed final network includes three facilities: two recycling plants and one transfer station. The municipality where each facility must be located, the capacity of them and the distribution network of the waste is also determined.

    Abstract: The aim of this paper is the identification of the location and capacity of the transfer stations and processing plants and the corresponding management network by means of an optimization model that minimizes: (i) medium transportation distance (ii) total management costs (installation, operation and landfill) with and without administrative predefined areas. The model is formulated as MILP problem where the binary variables represent the presence or not of management facilities at a location. GAMS is used as a high-level modelling system for the resolution of the mathematical programs. The obtained results show very different C&DW treatment networks with total cost ranging from 3.53 to 4.34 mill €/y and medium transport distance ranging from 14.77 to 24.10 km.

    Abstract: The main objective of this work is the development of the model which predicts the mobility of Pb and Zn under different scenarios of contaminated sediment-CO2 acidified seawater contact. The equilibrium results are fit to Freundlich isotherms and the adjusted parameters have been calculated. A porosity kinetic model of the evolution of Pb and Zn concentrations with L/S is proposed; the model allows to estimate the superficial diffusivity of the intra-particle Zn and Pb parameter as 5.43·10-12 cm2/s and 1.05·10-12 cm2/s, respectively.

    Contribution: Poster
    Abstract: A general super-structure is proposed for the design of a wastewater networks for removing five types of contaminants (suspended solids, heavy metals, inorganic salts, organic contaminants unsuitable for biological treatment and organic contaminants suitable for biological treatment) using until 13 types of Best Available Technologies (BAT) technologies. The removal of the contaminants follows a specified sequence to avoid reducing the efficiency in the downstream technologies. The application of this superstructure, which is modeled as an MINLP, is illustrated for the design of a wastewater network for a metal finishing industry.
