Adiquímica, along with the laboratory of Chemical and Environmental Engineering, University of Girona (LEQUIA-UdG) has been awarded the "Best Poster Award" during the "8th International Conference on Water Reclamation & Reuse" of the International Water Association (IWA) congress held in Barcelona last September. Under this format poster presented the paper "Control of fouling in MBR-RO coupled systems", championed by George Moreno of LEQUIA.
This paper evaluates a system that integrates a membrane bioreactor with a reverse osmosis unit as a potential process for urban waste water treatment obtaining an effluent with a very high quality of reuse.
According to research, the fouling of reverse osmosis membranes caused an increase in pressure, a decrease in permeate flow, and also a reduction in the efficiency of retention of salts.
The compounds responsible for the fouling, in the form of solid on the membrane were analyzed and characterized in order to optimize the process of osmosis.
The ultimate goal of this study is to propose strategies to reduce or prevent such contamination (addition of chemical compounds, etc.).
Please find enclosed the full study published in the February issue of the journal Water Technology

En las desaladoras de agua de mar no siempre es posible realizar la captación del agua por medio de pozos playeros para conseguir una filtración natural en el terreno. Frecuentemente se debe recurrir a tomas de agua superficial. Las tomas abiertas son más utilizadas a causa de la alta capacidad de producción de las nuevas desaladoras. La toma abierta requiere que el agua sea sometida a pre-tratamientos mas complejos con el objetivo de eliminar las partículas arrastradas y en suspensión, así como la materia coloidal, orgánica y biológica.
El ensuciamiento de las membranas en las desaladoras de agua de mar provoca un problema operacional en las desaladoras.
