Characterization of Sludge Resulting from Chemical Coagulation and Electrocoagulation of Pumping Water from Fishmeal Factories

In the fishmeal industry, seawater is used to transport fish factories. Due this, “pumping water” with high concentrations of organic matter generated that treated via chemical coagulation before letting it into sea. The objective this study characterize and compare sludge obtained from conventional electrocoagulation process. A pilot plant was built next a plant. both methodologies analyzed for its proximal composition, iron aluminum content, fatty acid profile in contained fat. Electrocoagulation found produce higher concentration lipids ash, which indirectly confirmed removes more pollutants salts than coagulation. contents by were 4.2% 0.025%, respectively, while those 0.01% 4.8%, respectively. Aluminum comes sacrificial electrode tank, sum w-3 values (EPA + DHA) 12.5% 18.8% sludges processes, so we can assume oxidizing process their load, must be assessed as an alternative feed ingredient.
