Title: Weir spillway for treated sewage
Inventor: MIKUCKI JACEK
IPC: C02F1/00
Filed: 1998-12-03
Abstract: The spillway channel dimensions, i.e. side wall height and base width (8), are equal to twice the value of the cross-section of a steadily increasing water flow defined by an equation expressed in terms of the acceleration due to gravity and the side wall height. Water falls over the sides of the weir and down the spillway side walls (6) formed by the weir segments (3-5), to flow away along a linear path. The water flow (Q) is expressed by the following equation : Q = 2. square root of g.H<5/2>; where g = 9.81 m/s<2> ; and H = side wall height.
