Characterization of wastewater from the plant edible oil refiner ERASOL

Abstract

The pollution of the smattering waters and receiver bodies, is a dangerous
environmental problem actually. The Santiago de Cuba bay, the second most
important economic in the country, receives daily the environmental impact of the
27 pollute focus; being the food industry a sector socioeconomic with high incidence
in the pollution of its waters because of the discharge of a lot of quantity of wastewaters
without treatment from different process of this industry. The production of
the soybean oil (Glycine max) in the refiner plant of eatable oils ERASOL produce
approximately 72 m3 / d of waste that are poured directly in the bay without any previous
treatment. The aim of this work is the characterization of the wastewaters of the
refinated soybean oil having in mind the environmental parameters and the rules
of the Cuban pattern for the drain in receptor marine bodies. The analysis showed
that the bay receives a lot of wastewater from ERASOL with 9,7 pH, 40232,50 mg/L of
organic loads, 18537,13 mg/L of oils and 0,2 mL/L of sedimentable solids. These results
showed that wastewaters of the ERASOL plant don’t fulfil with the specifications of
the Cuban standard in marine bodies.
