WebDIALYSIS Dialysis is an old established procedure for reducing the salt concentration in samples. It requires filling a dialysis bag (membrane casing of defined porosity), tying the bag off, and placing the bag in a bath of water or buffer. Through diffusion, the concentration of salt in the bag will equilibrate, with that in the bath. WebPeritoneal dialysis is a treatment for kidney failure that uses the lining of your abdomen, or belly, to filter your blood inside your body. Health care providers call this lining the peritoneum. A few weeks before you start peritoneal dialysis, a surgeon places a soft tube, called a catheter, in your belly. flagowce oppo
