Analysis of the Industrial Effluent before Discharge into the sea, Case from Kamsar, Republic of Guinea

Abstract

Oil effluents are the main sources of contamination of aquatic ecosystems. The intensity of their impact depends on the quantity, density and toxicity in the discharge. This study examines the effectiveness of effluent treatment prior to discharge into the ocean at the Kamsar plant. Seventy-two water samples were collected over an eight-month period. They were analyzed using an incubator (Infra Cal TOG/TPH) for total oil/fat (THG). As a result, the effluent contains a high level of oil/fat, which varies according to the season, with an average of 85 ppm/day in the dry season and 178 ppm/day in the rainy season. These rates are higher than the norm (15 ppm/day). The high THG content in the water shows that it is not biodegradable and toxic. A modification of the plant has been proposed, with two anti-parallel flat separators (API) of one pump each.
