RODRIGUEZ, Valduvina Córdova et al. Composition of the residual liquors from Textile Combined Celia Sánchez Manduley. RTQ [online]. 2020, vol.40, n.3, pp. 502-516.  Epub 20-Nov-2020. ISSN 2224-6185.

The work describes the technological process of the Textile Combined Celia Sánchez Manduley and the composition of its residuals is evaluated, based on the determination of physical-chemical parameters that constitute pollution indicators. Liquid residual samples were taken at two points of the company, in the period between January and March 2019. The parameters determined were: concentration of heavy metals, fats and oils, pH, conductivity, DQO and DBO. The results revealed that the concentration values ​​of the heavy metals determined were within the Cuban norms for the dumping of residuals to the coastal zones. The rest of the parameters oscillated between values ​​below and above the limits established by the Cuban norm. It is concluded that in these residuals there are organic compounds, high values ​​of DBO, DQO, fats and oils, and that the industry expels a residual with insufficient treatment, resulting in a source of contamination to the Bay.
