<p>The process for waste water purification is distinguished in that full use is made of the change in pressure at each level of the purification chambers (2) and the removal of the gas from above the liquid level in these chambers (2), as a result of which conditions are set up which favour a better bonding of the oxygen from the air bubbles in the closed purification process, while it is also possible to recover energy. The container (1) for the implementation of this process is distinguihed in that it has one or more levels of purification chambers (2) for the waste water, and the open waste water purification vessel (7) is at the top level of the container (1). However, the waste water is drawn from the trough (9) leading into the chambers (2) and from the vessel (7) via the connecting pipes (4). In addition, the chambers (2) have interconnected channels (6) equipped with directional mixing devices (11) and ventilation devices (12).</p> |
