What is hemodialysis?

Hi doc, my 72-year-old husband has been in kidney failure since 2 months. Since he is not a good candidate for a kidney transplant, has been advised to undergo regular dialysis. What is hemodialysis? What are the indications for dialysis? How is it done? Can hemodialysis be done at home? What are the potential complications of hemodialysis?
