Abstract
La présente invention concerne la conception la plus convenable pour épurer les effluents industriels à l’échelle réelle. Selon l’invention, il s’agit d’un réacteur à flux continu obtenu grâce à une nouvelle conception du bioadsorbant sous forme de billes composites. L’invention concerne plus particulièrement un procédé de fabrication de billes composites formant une matrice poreuse à base d’alginate de sodium et la poudre des déchets de marbre. Les billes composites comportent des groupements fonctionnels susceptibles de retenir des corps dissous dans le dit effluent. Nous décrivons ci-dessous le procédé de préparation des billes composites d’alginate de sodium /déchets de marbre. L'alginate de sodium est un polymère anionique naturel obtenu à partir d'algues brunes, de formule brute nac6h7o8, c'est une chaîne composée de groupements carboxyles coo- et de l'ion sodium na+ (figure 1). L'alginate de sodium a été largement utilisé pour piéger les adsorbants dans les applications environnementales en raison de sa capacité à former des hydrogels avec des cations multivalents. La poudre des déchets de marbre désigne un carbonate de calcium à tissu compact ou cristallin. La poudre des déchets de marbre a montré une efficacité d’élimination de plus de 99% avec une cinétique très rapide.The present invention relates to the most suitable design for cleaning industrial effluents on a real scale. According to the invention, it is a continuous flow reactor obtained thanks to a new design of the bioadsorbent in the form of composite beads. The invention relates more particularly to a process for manufacturing composite balls forming a porous matrix based on sodium alginate and the powder of marble waste. The composite beads comprise functional groups capable of retaining substances dissolved in said effluent. Below we describe the preparation process for the Sodium Alginate / Marble Waste Composite Beads. Sodium alginate is a natural anionic polymer obtained from brown algae, of crude formula nac6h7o8, it is a chain made up of coo- carboxyl groups and of the sodium ion na + (figure 1). Sodium alginate has been used extensively to trap adsorbents in environmental applications due to its ability to form hydrogels with multivalent cations. Marble waste powder refers to hard-tissue or crystalline calcium carbonate. The marble waste powder has shown a removal efficiency of over 99% with very fast kinetics.
