A supplementary degassing system is disclosed herein for use with a bedside console of the type employed in a central delivery system in the event additional degassing is necessary. The system may also be incorporated in a dialysis machine as the main degassing system. The system includes a chamber for receiving a liquid to be degassed. The chamber includes: a liquid inlet; a gas outlet through which gas is withdrawn; a degassed liquid outlet from which degassed liquid is drawn; and a recirculation inlet for receiving at least recirculated liquid. A recirculation loop is also provided for recirculating and treating liquid from the chamber. The loop includes a variable-restriction assembly for regulating pressures and enhancing degassing. The variable-restriction assembly includes a variable restriction comprising an orifice and valve for adjustably controlling liquid flow through the orifice. A pressure sensor is also provided for (1) sensing the pressure of the liquid flowing to the variable-restriction assembly and (2) controlling the flow through the variable restriction in relation to the pressure. When used in combination with the bedside console, the gas outlet is connected to the bedside console's effluent pump and at least a portion of the liquid from the outlet of the chamber is directed to the liquid inlet for the console.
