Abstract: A method for nitrate removal from drinking water. The method includes adapting a sludge including hydrogenotrophic denitrifiers (HTDs) by dominating the HTDs in the sludge, cultivating a microalgae biomass, forming a microalgae-HTD biomass by cultivating a mixture of the adapted sludge and the cultivated microalgae biomass, nucleating a plurality of microalgae-HTD granules by cultivating the formed microalgae-HTD biomass in a sequencing batch (SB) mode with a constant HRT, growing the plurality of microalgae-HTD granules by cultivating the nucleated plurality of microalgae-HTD granules in an up flow (UF) mode with a reducing HRT, and continuous nitrate removal from nitrate-contaminated water with a minimum HRT over the grown plurality of microalgae-HTD granules.

Abstract: A system and method for providing advertising media to consumers is described. The system comprising image capture means, an image processing unit connected to the image capture means. In use, the image processing unit executing one or more pattern recognition algorithms on an image received from the image capture means to extract information from the image relating to consumers in the image. The system compiling a list of attributes associated with an individual consumer based on the extracted information. The system including an advertising media database, an advertising selection unit connected to the image processing unit and the advertising media database. In use the advertising selection unit selecting advertising media from the advertising media database based on the list of attributes. The system also including an advertising delivery unit connected to the advertising selection unit for delivering advertising media selected by the advertising selection unit.
