Nanoclay sorbents for dialysis

A wearable system for removing body wastes from a peritoneal dialysis fluid, comprising:

• a catheter having an inflow lumen and an outflow lumen in communication with a peritoneal cavity of a patient;
• a fluid circuit for circulating the peritoneal dialysis fluid to and from the peritoneal cavity;
• a quantity of the peritoneal dialysis fluid within the fluid circuit;
• at least one pump attached to the fluid circuit for circulating the peritoneal dialysis fluid into and out of the peritoneal cavity and through the fluid circuit;
• a replaceable cartridge housing coupled to the fluid circuit, the housing having a first end including an inlet, and a second end including an outlet;
• a filter with processed nanoclay particles, the filter coupled to the fluid circuit for removing the body wastes from the peritoneal dialysis fluid, wherein the processed nanoclay particles comprise a processed clay having at least one dimension from 1 nm to 200 nm, and wherein the processed nanoclay particles have been chemically enhanced with an acid to increase an acidity such that urea uptake is increased;
• and
• a discharge path coupled to the fluid circuit allowing the peritoneal dialysis fluid to be drained after a treatment period.
