PCT No. PCT/EP93/00349 Sec. 371 Date Nov. 17, 1993 Sec. 102(e) Date Nov. 17, 1993 PCT Filed Feb. 12, 1993 PCT Pub. No. WO93/20918 PCT Pub. Date Oct. 28, 1993.A method and apparatus for charging either a a shallow grit tank or a settling tank with waste water by means of a horizontal feed line and a horizontal drain line using the Coanda Effect. The waste water is pressured through a gap which directs the waste water stream onto a curved surface. Due to the Coanda Effect, the direction of the waste water is changed from downward when used in a shallow grit tank or changed from upward when used in a settling tank, to a substantially horizontal direction. The mineral constituents and the organic constituents of the waste water are consequently separated. |
