Abstract
An apparatus for extruding a block product from a feed material. A barrel includes an output end. A screw is at least partially disposed within the barrel. The screw flows the feed material in the barrel towards the output end. A die is in fluid communication with the output end of the barrel. The die receives the feed material and heats the feed material to produce the block product. At least one electrically conductive element passes electric current through the feed material to heat the feed material by resistive heating. The feed material may include activated carbon and at least one binder, to produce a carbon block product.

An apparatus for extruding a carbon block for water filtration from a feed material comprising activated carbon, the apparatus comprising:
- a barrel comprising an output end;
- a screw at least partially disposed within the barrel, and adapted to flow the feed material in the barrel towards the output end;
- a die in fluid communication with the output end of the barrel, and adapted to receive the feed material and heat the feed material to produce the carbon block;
- and
- at least one electrically conductive element for passing electric current through the feed material to heat the feed material by resistive heating.
