Efficiency Of Micro-Nanobubbles for Wastewater Treatment in Puerto Bermúdez, Oxapampa, Pasco
Keywords:
micro-nanobubbles, Total coliforms, physico-chemical parameters, biological parametersAbstract
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%.
