The treatment showed absence of total coliforms and E. coli, MPN <1.1 P. aeruginosa and 98.7% reduction for heterotrophic. The heat recovery has great importance since it increased productivity by 110%. The solar radiation cutting level for the pasteurizer is at about 6.6 MJ/m2 day. The solar pasteurizer (2 m2 collector) produce 80 L/day, with 85 °C treatment temperature for 15 s. The system guarantees total segregation between the contaminated water and the water in treatment.
