Some embodiments are directed to a decomposing and collection apparatus for use with a fluid. The apparatus includes an assembly for generating ions via applying atmospheric pressure, low temperature plasma to the fluid and separating the generated ions. The assembly includes multiple plasma generator and separator units that are vertically stacked relative to each other. Each of the multiple plasma generator and separator units includes a plasma generator for generating the generating atmospheric pressure, low temperature plasma, and a separator disposed to receive the positively and negatively ions ejected from the plasma generator and configured to redirect the received positively charged ions in one direction and the received negatively charged ions are redirected to another direction different from the one direction. The apparatus also includes a collector configured to collect at least one of the redirected positively charged ions and the negatively charged ions.
