In this research UF of cutting-oil by three different polymeric membranes (regenerated cellulose (RC), polyacrylonitrile (PAN) and polyetherimide (PEI)) is presented. The membrane flux (J) in dependence of time (t) was studied. Surface and structural properties of membrane are very important for their permeability, which defines the capacity of filtration device. Therefore physical parameters as contact angle and streaming potential of membranes were analysed. Considering the results of these measurements the applicability of polymeric UF membranes and their surface behavior were determined. The tests showed that among three different UF membrane materials, regenerated cellulose showed the best performance in terms of the water flux and fouling tendency, due to its good hydrophilicity.
F.18 Transfer of new know-how to direct users (seminars, fora, conferences)
COBISS.SI-ID: 17547798We propose and applied a computer-aided framework for the design of water treatment and reuse networks based on a novel multilevel global optimization method. In the framework, optimization methods, problem analysis tools and wastewater engineering knowledge are integrated in a computer-aided environment, in order to facilitate the formulation and solution of the design problems.
F.23 Development of new system-wide, normative and programme solutions, and methods
COBISS.SI-ID: 17185046A computerized code for the synthesis of optimal processes for waste-water treatment of oil-in-water emulsions was developed. For a given COD value, the code identifies the optimal combination of treatment techniques with maximum profit as the objective function. As a result, a flexible treatment scheme can be proposed for O/W emulsions with COD values up to 100.000 mg/L.
F.09 Development of a new technological process or technology
COBISS.SI-ID: 17120278This work presents the application of the generic multi-period model for efficient synthesis of biorefinery supply networks at the continental level. The model explores specific regional characteristics for the production and supply of biofuels. Several the most advanced biofuels production technologies are considered and embedded within the biorefinery supply networks as surrogate models in order to handle the complexity of large-scale supply networks. Economically-optimal solutions are obtained by considering sustainable biomass production while preventing the usage of food for energy.
