Baseline of the behavior of wastewater discharges in the cnic company

Abstract

This paper presents the main results obtained from the wastewater behavior analysis in the National Center for Scientific Research Company. For this, the information of the analytical results issued by the accredited Laboratory "Group of Management of Technical Scientific Services-DECA" (according to the NC-ISO/IEC 17025:2017), was collected and analyzed, referring to the characterization of wastewater that are generated in the center, considering a period of 15 years of sustained work. The investigation considered two stages, an initial one in stable conditions of the activities of the institution and a second one, in which new discharges generated from the diversification of the productive processes and their impact on the environment are introduced. In addition, it took into account the legal framework protected by current Cuban regulations on wastewater discharges. The study allowed characterizing the liquid waste, not only from the physical-chemical point of view, but also from its biodegradability, the organic load disposed to the sewage system and its contribution to the community treatment system. In this way, the baseline is identified and established from which the behavior evaluation of discharges originating from the incorporation of new lines of production or services will be maintained, due to the reorganization of the enterprise towards sustainable marketing, with the control of compliance with environmental regulations
