Abstract
Improvements in sewage water aeration systems.The system is the type that includes water recirculation piping (1), air piping (2) that flows in parallel to the first, in such a way that by using ejectors (3) and (4) and a random system the recirculated water is mixed with air formed into a cloud of bubbles that are injected by said ejectors (3) and (4) inside the heart of the sewage water in a tank (6).The improvements are designed to visibly reduce losses in the water load while being circulated by the system, as well as provide an important price reduction in production, which is achieved by the introduction of plastic materials that also reduce friction and load loss.These improvements are centred on the ejectors (3) and (4), both in the structure and distribution that enables the air bubbles in the liquid to be inside for longer, at the same time as said water is rotated that then enables improved oxygenation to occur.<IMAGE>
