BAZUA-RUEDA, E.R. et al. Chemistry applications to wastewater treatment: case studies in Mexico and Cuba. Rev Cub Quim [online]. 2019, vol.31, suppl.1, pp.105-133. ISSN 2224-5421.

The authors had an academic meeting to face the challenge to provide clean water and to dispose of wastewaters once treated to reduce pollution impacts and to recycle the treated effluent. Chemistry plays a substantial role to the solution of removing pollutants since chemical reactions are crucial to increase the final quality of the treated effluents. A viable option might be the installation of units using the artificial wetlands technology. There microbial consortia carry these chemical reactions. Two case studies were considered, Mexico and Cuba. An example of the use of artificial wetlands to solve the lack of sanitation facilities for Mexico City’s Tlalpan section is given using as example two prototype plants located near this neighbourhood so that climate conditions will not interfere in the chemical reactions. The equivalent is given for a zone Havana City considering the Almendares river and the environmental impact on it.
