Abstract
Wastewater from cleaning the isotank There are many types of chemicals. It is another cause of wastewater that is difficult to treat. But with today's industries, chemicals still need to be transported on a regular basis. And how widely used Is the isotank transport Therefore applied the principles of physics engineering to design a wastewater treatment machine The waste water pump is injected into a capillary to increase the area of wastewater exposed to ozone in high pressure plasma systems. In this study, 800 mg / h of ozone was applied to 20 liters of wastewater with a flow rate of 60 liters per hour. As a result, the quality of the water used to measure water was dissolved oxygen (DO), BOD and COD of wastewater. In a short time, the DO increased from 0 to 4 mg / l in 24 minutes. Statistical analysis with R2 = 0.903 approaching 1 showed that increased DO was significantly associated with time, whereas BOD. Decreased 32.79 percent from 6,550 to 4,402.33 milligrams per liter in 12 minutes. The value R2 = 0.708 approached 1, indicating that the reduction of BOD was highly time-related and the COD decreased 14.23% from 14,375.33 down to 12,330 mg / l in 24 minutes. R2 = 0.871 close to 1 indicates that COD reductions are related to high time as well.
