Abstract: Systems, devices, and methods including: generating a 3D virtual space for a given point of interest (POI); determining whether a set of user preferences are available within the generated 3D virtual space and customize the 3D virtual space based on the availability of the set of user preferences; determining a generated 3D environment based on the customized 3D virtual space and availability of the set of user preferences, wherein determining the generated 3D environment is further based on receiving data from a set of components; and updating the generated 3D environment to customize the 3D virtual space for a user based on receiving data from at least one of the components from the set of components, and wherein the set of components are being continuously executed in real-time thereby syncing the functions of a set of devices present in a virtual world environment with a set of devices present in a physical world environment.

Abstract: A process for separate removal and recovery of heavy metals from industrial wastewater is provided. The wastewater to be treated flows through adsorbents after filtration and adjustment of a pH to about 3 to 7 to obtain the adsorbents which have adsorbed corresponding heavy-metal ions, which are then eluted from the corresponding adsorbents using an acidic solution such that eluates containing the corresponding heavy-metal ions are obtained.
