Nano-enabled activated carbon blocks to enable removal of oxyanions from water
A method for preparing a nano-enabled activated carbon block, a nano-enabled activated carbon block produced by the method, a household water filtration system comprising the nano-enabled activated carbon block, and a method for filtering tap water using the household water filtration system are provided. The method includes contacting a solution including a metal(lic) precursor (e.g. a titanium compound and/or an iron compound and/or a zirconium compound) with activated carbon particles such that the solution fills pores of the activated carbon particles. The method further includes causing a metal (hydr)oxide (e.g. titanium dioxide and/or zirconium dioxide and/or iron oxide) to precipitate from the solution thereby causing metal oxide nanoparticles to become deposited within pores of the activated carbon particles. The method also includes preparing a nano-enabled activated carbon block from the activated carbon particles having metal oxide nanoparticles deposited within the pores thereof.

System and Ultrahigh Pressure Extrusion Method for Making Extruded Granular Sorbent with Post-Extrusion Cold-Processing of Extruded Granular Absorbent for Size Control
A method, system and machine for cold processing extruded starch-containing pellets by cold particle size reducing pellets of a size greater than a particle size reduction setting size enabling particle size reduction to be performed without compacting or compression any size reduced particle while doing so without heating them during particle size reduction thereby preserving their pores, internal liquid absorbing voids and starch matrix optimizing granular sorbent performance. Such a method, system and machine is selectively controllable enabling not only control of how many and a ratio of fines produced relative to the final product providing real time control of fines production but also is able to provide particle size distribution control as well. A preferred particle size reduction machine is a roll granulator that breaks larger size pellets into smaller sized particles and/or fines without compressing or compacting them with the spacing between the rolls selectively variably in a manner that regulates how much of different sized particles and/or particles falling within certain size ranges are produced advantageously enabling real time control of particle size distribution to be achieved during extruder line operation.
