Abstract
The present invention provides a hemodiafiltrator comprising two compartmentalized dialysate chambers coaxially arranged in tandem. A single packed bundle of hollow fibers for blood flow is enclosed coaxially along a longitudinal axis inside the dual dialysate chambers. A configuration of a tandem arrangement of the dual dialysate chambers at least comprises a first dialysate chamber for an acidic dialysate with a varying level of urea and a second compartmentalized dialysate chamber for a basic dialysate with no urea but with a level of ammonia up to a level detected in normal human blood.
