AN AUTOMATED ATMOSPHERIC WATER GENERATOR FOR PRODUCING HIGH QUALITY WATER FOR DRINKING AND BIOMEDICAL APPLICATIONS.

摘要

An integrated Atmospheric Water Generator(AWG) capable of selectively producing three different types of water (i)potable, (ii)alkaline an (iii)demineralised water of biomedical grade comprising a vapour compression refrigeration unit for condensation of atmospheric moisture involving a vapor condensation unit including forced suction of atmospheric moist air involving fan means ducted to evaporator; said evaporator maintained below dew point temperature by circulation of refrigerant; said moist air on contact with cold surface of evaporator looses heat and condenses into water droplets; collection tray/trough for collecting the thus generated water droplets and cooperatively integrated with membrane-based ultrafiltration, controlled essential chemical dosage and reverse osmosis(RO) membrane system, incorporated with an indigenous high flux polyetherurea membrane in single pass to obtain 2ppm TDS or cascaded two-stage arrangement with resin to achieve water quality of less than 1ppm TDS., thereby to produce three different types of water, namely potable, alkaline and demineralised water of biomedical grade.
