Efficiency Of Micro-Nanobubbles for Wastewater Treatment in Puerto Bermúdez, Oxapampa, Pasco

Romulo Reyes, Jhonny Valverde Flores


In our country, the wastewater discharges affect to water bodies, public health and as well as different ecosystems without any kind of treatment. For this reason, a different and effective treatment is proposed for the minimization of total coliforms present in the wastewater from Puerto Bermudez, Oxapampa, Peru with the generation of air micro-nanobubbles. The degree of contamination shown in the different physico-chemical and biological parameters was determined; as well as their impact’s minimization to obtain a better quality of life.

The research was experimental, the assembly of the air micro-nanobubbles generator was done to get treatment by dosage. The analysis were carried out to determine the degree of contamination and thus treat them with air micro-nanobubbles in different quantities and thus have the best result. The results of the treatment with air micro-nanobubbles were favorable.  The efficiency achieved was 66.21%.
