Abstract: The present invention is a self-regenerating biofilter. The biofilter tank receives untreated water through an intake inlet, filters it through a filtration mass and expels purified water through an output outlet. The filtration mass includes gravel and activated carbon layers separated by a mesh screen. A compressed air line is located below the mesh screen.

The biofilter self-regenerates by periodically stopping filtration for a time, allowing biological matter left on the activated carbon to degrade into biomass. Periodically, the biofilter removes and flushes out biomass by application of water or a combination of air and water.

Abstract: The permeability of cementitious materials is reduced by chemically functionalizing the surface and infiltrating it with a lubricant. However, the development process was not trivial, where additional steps were required to optimize the cement types used (e.g. geopolymer and Portland cement). It was observed that after the complete modification, the wetting behavior of the cement against water changed from dynamic wetting to hydrophobic (water droplets with water CA>120°. Furthermore, compression testing showed that there was negligible difference in the bulk mechanical properties, more specifically the ultimate strength and the Young's modulus. The result is cementitious materials with omniphobicity and damage-tolerant resistance to permeable fluids.
