摘要： A mixture of air and paper stock (36) made from recycled paper from which the ink particles have been chemically released is injected into a cylindrical processing vessel (22). Added surfactants create a foam (40) from the air as it rises through the stock (36) and cause the ink particles to adhere to the air bubbles, resulting in a foam containing a concentrated fraction of the ink particles with some included fibres. The foam rises to the top (43) of the vessel (22), and carries with it ink particles. Additional air injection ports (53) can be used to increase the amount of foam generated and the amount of ink removed. Flow of stock (36) and foam (42) from the vessel (22) can be controlled by adjusting valves (70) on the stock (34) and foam outlets (44, 56). Flotation sensors (60) allow the foam head to be maintained at the stock level by controlling the rate at which foam (42) is withdrawn through the foam outlets (44, 56).
摘要翻译：由再循环纸制成的空气和纸料（36）的混合物被注入到圆柱形处理容器（22）中，所述再循环纸已经将墨颗粒化学释放。添加的表面活性剂在空气上升通过原料（36）时产生泡沫（40），并使油墨颗粒粘附到气泡上，产生含有浓缩部分的油墨颗粒和一些包含纤维的泡沫。泡沫上升到容器（22）的顶部（43），并带有墨水颗粒。可以使用额外的空气注入口（53）来增加产生的泡沫量和去除的油墨量。可以通过调节原料（34）和泡沫出口（44,56）上的阀门（70）来控制来自容器（22）的原料（36）和泡沫（42）的流动。浮选传感器（60）通过控制泡沫（42）通过泡沫出口（44,56）排出的速度而使泡沫头保持在存储水平。
