DEVELOPMENT OF A NOVEL PROCESS TO REMOVE HEAVY METAL FROM WASTE WATER AND CONVERTING SULPHATE IONS INTO VALUE ADDED CHEMICAL AND IMPROVING THE QUALITY OF WATER FOR COMMERCIAL APPLICATION

摘要

The technology is based on complexation of metal impurities present in the waste water. The anionic biopolymer complex metal impurities and precipitate out from the solution. Polyols (poly hydroxy polymer with carboxylic acid) have a tendency to form complexes with poly-valent metals which result into precipitation. The usage of poly-valent metal is advantageous due, its high affinity towards polyols and the carboxylic group, thus accomplishing an efficient process. The agglomerates or precipitates formed can be easily separated out via filtration or distillation. Here I address the concerns for the removal of sulphate ion by using the metal salt of the organic acids such as barium, lead, mercury, silver, calcium, and rhodium. Technology is based on green chemistry which uses environment-friendly organic acid reagent which devoid of any storage requirement. Such technologies are state-of-art for the water and commercial market, thus technology would prove to have a huge potential for upcoming water treatment and recycle systems.
