some people use dialysis machine for purification of blood and throwing waste outside . As there both or one kidney is damaged . If one kidney is damaged then dialysis must be done twice or thrice in a week . if both are damaged then dialysis must be done daily or alternate days on a week .In this process nearly 500ml blood is taken out and then purified . Thus the pure blood is passed back in body.It functions same as kidney

Answer :
Some people need to use the dialysis machine as the kidneys of those people are unable to work efficiently due to some diseased condition or kidney damage.
Thus to rid the body of nitrogenous wastes the dialyzer is used which works as an artificial kidney.
The principle behind the working of the dialyzer is diffusion of solutes and ultrafiltration of fluid across a semi-permeable membrane. This is the same principle followed by the nephrons of the kidney for the production of urine.
