Operation
- The system is implemented in the following steps:
- 1- Screen. The thick solids dragged by the water are intercepted by an automatic circular grinding grate at the entrance to the RCA1 type equipment.
- 2- Biological oxidation: In the biological reactor, the biological decomposition of organic matter takes place thanks to the supply of air and the generation of aerobic microorganisms. In contrast to conventional total oxidation, the reactor works with higher concentrations of solids, so that more oxygenation is required and, as the sludge age is higher, higher treatment yields are obtained.
- 3- Filtration: Solid-liquid separation is achieved by filtration using membrane technology. By means of a suction system, a vacuum pressure is exerted on the membranes, creating an outside - inside flow so that the water penetrates through the membranes, leaving the solids and bacteria on the outer wall. The diffusers create an upward air flow which cleans the outer wall surface of the membranes and ensures aerobic conditions. The water is chlorinated by dosing sodium hypochlorite, thus preserving the sanitary properties of the effluent and ensuring the reuse of the water for residential use.
- 4- Outlet: The system is completed with a permeate extraction pump followed by a flow meter that controls the system to operate at a constant flow rate. This is produced thanks to the action of a frequency variator that acts on the pump. In addition, a pressure transmitter is incorporated to ensure that the membranes work under optimum conditions.
