Abstract: A nanoadsorbent based filter is used for purification of fluoride and arsenic contaminated water. 140-150 g low cost (˜10 USD/kg) nanoparticles of gamma alumina of 20-25 mg/g fluoride and 25-30 mg/g arsenic adsorption capacity is incorporated in propylene filter without susceptibility of leaching incorporated nanoparticles in water. The cost of domestic defluoridation device containing low cost nanoalumina incorporated filters/cartridges along with housing, overhead tank, tubing and treated water storage container etc. is of very low cost of around 25 USD/device. The fluoride treatment cost would be <0.5 USD/100 lit for 4-5 mg/l fluoride water after 2-3 regenerations while, the arsenic treatment cost using domestic filtration device would be <0.25 USD/100 lit for 90-100 ?g/l arsenic (III) water.

Abstract: A device may receive video data associated with a video, and may identify image data associated with the video data and that corresponds to a frame of the video. The device may process the image data, with an image analysis model, to determine an image compliance score associated with a policy and with context of the image data, and may identify text data associated with the video data. The device may process the text data, with a text analysis model, to determine a text compliance score associated with the policy and with context of the text data, and may determine, based on the image compliance score and the text compliance score, an aggregate compliance score associated with the frame. The device may determine whether the aggregate compliance score satisfies a threshold associated with the policy, and may perform actions based on whether the aggregate compliance score satisfies the threshold.
