THE USE OF NANO ALLOYS IN WASTEWATER TREATMENT
(FR)
UTILISATION DE NANO-ALLIAGES POUR TRAITER LES EAUX USÉES
Abstract:
(EN)
The world is facing formidable challenges in meeting rising demands of clean water as the available supplies of freshwater are depleting due to (i) extended droughts, (ii) population growth, (iii) more stringent health based regulations and (iv) competing demands from a variety of users [ 1,2,3]. The protection of water treatment systems against potential chemical and biological terrorist acts is also becoming a critical issue in water resources planning [3, 4]. Today a number of techniques are used for treatment of water i.e. chemical and physical agent such as chlorine and its derivatives, Ultraviolet light [5], Boiling, Low frequency ultrasonic irradiation [6]. Research is underway to use advance nanotechnology in water purification for safe drinking [7]. Nanotechnology used for detection of pesticides [8] chemical and biological substances including metals (e.g. Cadmium, copper, lead, mercury, nickel, zinc), Nutrients (e.g. Phosphate, ammonia, nitrate, nitrite), Cyanide Organics, Algae (e.g. Cyanobacterial toxins) Viruses, Bacteria, Parasites, antibiotics and Biological agents are used for terrorism. Innovations in the development of novel technologies to desalinate water are among the most exciting and seem to be promising [9]. In this patent we introduce a new nanotechnology technique based on nanoparticles for waste water treatment with efficiency up to 94%. By adding thes Ίe Nanoparticles to the waste water, which adsorb all the dye and heavy metal elements. The Nanoparticles loaded with heavy metal elements were collecting using a powerful treatment unit within 10 minutes only. Most of the other waste water treatment techniques have problems in their recyclability and production cost on a large scale. However, we overcame these problems through these recyclable, low cost nanomaterials.
(FR)
La présente invention concerne le traitement des eaux usées au moyen d'une nouvelle technique faisant appel à des nanoparticules, avec une efficacité allant jusqu'à 94 %. Les nanoparticules de l'invention sont ajoutées aux eaux usées et adsorbent tous les colorants et les métaux lourds. Les nanoparticules chargées avec les métaux lourds sont ensuite collectées au moyen d'une unité de traitement performante en moins de 10 minutes. Les nanomatériaux de l'invention sont en outre recyclables et peu coûteux. L'invention apporte ainsi une solution au formidable défi auquel le monde fait face pour répondre à la demande croissante en eau potable, les réserves en eau douce diminuant en raison (i) des sécheresses prolongées, (ii) de l'augmentation de la population, (iii) des réglementations basées sur la santé de plus en plus contraignantes et (iv) des besoins de divers utilisateurs en compétition [1, 2, 3]. La protection des systèmes de traitement d'eau contre d'éventuelles attaques chimiques et biologiques par des terroristes devient également un problème critique pour planifier les ressources en eau [3, 4]. De nos jours, un certain nombre de techniques est utilisé pour traiter l'eau, par exemple les agents chimiques et physiques tels que le chlore et ses dérivés, la lumière ultraviolette [5], l'ébullition et les rayonnements ultrasonores à basse fréquence [6]. Des recherches sont en cours pour mettre au point des nanotechnologies capables de rendre potable l'eau [7]. Les nanotechnologies utilisées pour détecter les pesticides [8], les produits chimiques et les substances biologiques, notamment les métaux (par exemple le cadmium, le cuivre, le plomb, le mercure, le nickel, le zinc), les nutriments (par exemple, le phosphate, l'ammoniac, le nitrate, le nitrite), les substances organiques à base de cyanure, les algues (par exemple, les toxines cyanobactériennes), les virus, les bactéries, les parasites, les antibiotiques et les agents biologiques sont utilisées pour le terrorisme. Les innovations permettant de développer de nouvelles technologies destinées à dessaler l'eau sont particulièrement excitantes et semblent être prometteuses [9].
