Abstract: ABSTRACT OF THE DISCLOSURE        A liquid containing suspended solids is first passed through an electrostatic treater, having no current flow across its electrodes, to initiate nucleation and coagulation of the particles.  Thereafter, it passes through an electrolytic treater wherein current may flow between the electrodes to further en-courage coagulation to such an extent that flocculation begins. The residual effects of the electrostatic treater prevent plating out on the electrodes of the electrolytic treater such that electrolysis can occur without sacrificing an electrode, and the electrodes are so arranged that the liquid passes sequentially through groups of concentrated lines of force whose repetitious, powerful action further encourages flocculation.  From the elec-trolytic treater, the liquid with its flocculated material is delivered into a clarifying basin so designed that the floc will settle out and be removed from the basin with a minimum of manipu-lation because of the tendency of such material to immediately dissipate and disperse when handled while still in the liquid.

Abstract: Abstract of the Disclosure In the case where a two-wire circuit forming a trunk or a line circuit of a two-wire system is converted by a hybrid circuit to a four-wire circuit having sending and receiving paths to form a transmission line between subscribers, if an impedance variation on the two-wire side is large, a leak from the sending path to the receiving path occurs and is amplified to cause singing.  To eliminate the singing, a circuit for detecting the impedance fluctuation of the two-wire side is inserted in the two-wire circuit, and a switching device inserted in the four-wire circuit is activated by an impedance detecting signal of the detecting circuit to electrically open the four-wire circuit, thereby preventing the singing phenomena.  This method does not involve the use of an expensive attenuator which is troublesome to design for preventing singing.
