Abstract
Pervious concrete (PC) is considered a solution to reduce the effects of heat islands, runoff problems, as well as reduce the concentrations of pollutants present in the water; however, its potential as a filter bed is used in the treatment of sanitary sewage has never been evaluated. This work aimed to evaluate the influence of photocatalytic TiO2 addition in PC on the concentration of total phosphorus, total ammonia, nitrate, total solids, and turbidity for application in the treatment of sanitary sewage. Sunlight was used as a radiation source. A flat photocatalytic reactor was built, in which 100 liters of raw sewage were pumped, with a flow of 100 L/min over the PC slabs, covering a total area of 1 m². The TiO2 concentrations added to the PC were 3, 6, and 10%. The results indicate efficiency in the adsorption of total phosphorus, total ammonia, nitrate, total solids, and turbidity. Thus, the use of PC associated with 10% TiO2 can add efficiency to the sanitary sewage treatment process by maintaining good mechanical and hydraulic behavior.
