A process for the purification of inorganic nitrogen laden waste water and or water
The process relates to the purification of inorganic nitrogen laden waste water by eliminating nitrate nitrogen using mutated strains. This has enormous potential application in the treatment of various industrial effluents.
A process for the purification of Escherichia coli contaminated water for reusable option. 
The present invention provides process for purification of Escherichia coli (E.coli) contaminated waste water using alkali metal sulphide followed by passing through the reactor packed with activated carbon. The treated water can be reused.
The process has enormous potential applications for supplementing the inventory towards recreational water, bath water, industrial cooling water, industrial processing water and agricultural water by sewage, duly freed from E.coli, thereby ensuring reuse of water leading to substantial reduction in fresh water requirement. The process has already been transferred to industry.
The invention has been applied for Patent protection (Indian Patent application no. 1110DEL2001;Patent pending).
A process for recovery of salt from salt laden water containing dissolved organics for reusable options
The present invention provides process for recovery of salt from salt laden water containing dissolved organics using oxidizing agent under acidic condition to remove the dissolved organics. Other chemical and biological impurities present in the water containing salt and dissolved organics can be removed by passing the same through activated carbon of specific characteristics. Water free from dissolved organics, evaporated under sun light provide salts for reusable option. The process has already been transferred to industry.
The invention has been applied for Patent protection (Indian Patent application no. 317DEL2004;Patent pending).
A novel catalyst useful for the removal of pathogens from waste water
The present invention provides a novel catalyst useful for the removal of enteric and other pathogens from waste water. The process relates to the treatment of domestic and industrial waste water contaminated with enteric and other pathogens with metal ion impregnated activated carbon, whereby the pathogens such as Escherichia coli, Shigella species, Salmonella species are completely destroyed during the treatment resulting in no recurrence or regrowth of the organism. Thus the water, treated and purified thereby, can be reused.
This process has enormous potential applications for supplementing the inventory towards recreational water, bath water, industrial cooling water, industrial processing water and agricultural water by sewage duly freed from enteric pathogens such as Escherichia coli, Shigella species, Salmonella species, thereby ensuring reuse of water leading to substantial reduction in fresh water requirement.
The invention has been applied for patent protection (Indian Patent application no. 2497Del2005; patent pending). The technology has already been transferred to industry.
A novel third phase electrode for electrocatalytic treatment of waste water
The invention provides a novel third phase electrode comprising surface etched nickel impregnated mesoporous activated carbon (SENIMAC). The process of waste water treatment with yeast immobilized macroporous activated carbon employs SENIMAC as the third phase electrode in an electrocatalytic reactor. A process is provided for electrocatalytic purification of waste water containing Chemical Oxygen Demand (COD) not more than 50000 mg/l and Total Dissolved Solids (TDS) not more than 70000 mg/l generated from different industrial sectors. The process of the present invention also reduces the treatment cost of wastewater significantly. The treatment process exhibits an efficiency upto 90% and 86% for COD and TOC respectively.
The invention has been applied for patent protection (Indian patent application no. 759Del2006; patent pending). The technology has already been transferred to industry.
