Domestic and non-domestic wastewater generation and release, 2010

Domestic discharges

Wastewater produced 7.63 km3/year (242 m3/s)

Collected in the sanitary system 6.50 km3/year (206 m3/s)

Treated 2.35 km3/year (74.4 m3/s)

Organic charge generated 2.06 million of tons BOD/year

Collected in the sanitary system 1.75 million of tons BOD/year

Removed during treatment 0.52 million of tons BOD/year

Non-domestic discharges (including industrial)

Wastewater produced 5.77 km3/year (183 m3/s)

Collected in the sanitary system 0.87 km3/year (27.7 m3/s)

Organic charge generated 6.74 million of tons BOD/year

Removed during treatment 0.82 million of tons BOD/year

Capable to generate non selective, highly oxidizing species.

Able to degrade organic compounds or mineralize it to CO2 and water.Some AOPs may use solar radiation as driven force in restoration processes.

Solar photocatalysis (SP) is the AOP currently in use for water treatment

ConclussionsWater decontamination and disinfection is possible using solar driven advanced oxidation processes.

Fenton and Fenton like processes demonstrate high efficiency for organic pollutants degradation in short periods of time.

Some of these processes are currently on use at industrial application in developed countries. It is interesting assess the feasibility of using experience generate so far for applications in our country.
