A sorbent assembly, comprising:
- two or more sorbent pouches stacked in series;
- the two or more sorbent pouches formed from a porous material wherein the sorbent pouches contain at least one sorbent material and the porous material allows fluid to pass through the sorbent pouches;
- wherein at least a first of the two or more sorbent pouches contains solid urease, and wherein the porous material substantially retains the solid urease in the first sorbent pouch.
A system, comprising:
- a sorbent assembly comprising at least one sorbent pouch containing alumina;
- and
- an injector fluidly connected to a flow path containing the sorbent assembly;
- the injector configured to inject a urease solution into the flow path upstream of the sorbent assembly allowing the urease in solution to bind to the alumina contained in the sorbent pouch.
