OxTube - fast and efficient way to aerate water. Even with POME wastewater treatment.
Solution that increased DO in POME process from 0,1 mg/l to over 2 mg/l - interested? In POME wastewater treatment aeration plays important role and is usually energy consuming. This can be changed and fast. SansOx delivered one solution, OxTube, to one of the POME wastewater treatment plants and it was connected to pump that moved wastewater from the settling pond to the aeration pond. OxTube dissolves air into water very efficient way and within 1 second and this way increase the DO in the aeration pond. The size of the pond was 2000 m3 and in the beginning (starting in the beginning of May) OxTube aeration was used only 8 hours per day. This was because the pump task was to move water from settling pond to aeration pond and 8 hours per day with this was enough. The aeration pond has three surface aerators, but this was not clearly enough as the DO in the aeration pond was in average of 0,1 mg/l. DO number was not changed But COD started to decrease from over 1500 mg/l to less than 1000 mg/l. Unfortunately, this did not affect to DO which stays low and the smell still existed. In the beginning of June the running mode was changed and for 8 hours the pump still pumped waste water from settling pond to aeration pond. After this, for 16 hours per day, the pump pumped the water from aeration pond through aeration process (OxTube) back to aeration pond. This decrease the COD even more but also increased the DO level to totally new level as can be seen the enclosed graph. Also the smell was a lot less and the treatment after this was easier and the discharge water quality improved. Would this work similarly in your POME wastewater treatment plant? Interested? One thing is certain, OxTube will increase the DO in the water and in several cases totally even without extra energy as OxTube uses the existing flow of water as the source of energy.
