<p>A static foam generating apparatus includes a pipe (12) having an inner diameter, an axis, an input end, and an output end. A plurality of perforated discs (26) are disposed in the pipe (12), the discs (26) positioned parallel to each other and perpendicular to the pipe (12) axis. A plurality of spacer rings (28) are disposed within the pipe (12), a spacer ring (28) separating each perforated disc (26) from each adjacent perforated disc (26). A method for generating foam includes the steps of providing a static foam generating apparatus including a pipe (12) having an inner diameter, an axis, an input end, and an output end, supplying feed water to the pipe (12), supplying surfactant to the pipe, and supplying air to the pipe (12).</p> |
