LAUTECH Journal of Engineering and Technology https://laujet.com/index.php/laujet <p>LAUTECH Journal of Engineering and Technology (LAUJET) is a leading internationally referred journal in the fields of science, engineering and technology. It is a journal founded by academicians, educationists with substantive experience in industry. The journal is an online open access journal with a yearly print version of its volumes/issues made available to interested persons/institutions. The basic aim of the journal is to promote innovative ideas in fields relating to the sciences, engineering and technology. The basic notion of having a wide area of focus is to encourage multidisciplinary research efforts and seamless integration of diverse ideas that might be gleaned from the papers published in the journal.</p> <p>&nbsp;</p> en-US jekaysol@yahoo.com (Engr.

This study focuses on the performance of the electrocoagulation process for the treatment of rubber latex wastewater (RW) using Aluminum-Aluminum (AL-AL) and Aluminum-Carbon (AL-C) electrodes. Rubber latex wastewater (RW) was obtained locally from the plastic industry in Araromi-Obu, Ondo State of Nigeria with an initial concentration of 7.30, 28°C, 65.53mg/L and 785.23mg/L for pH, Temperature, BOD, and COD respectively and subjected to electrocoagulation using (AL-AL) and (AL-C) electrodes. Effects of electrocoagulation time and electrode types were studied and achieved under the following initial conditions of 30V, current density of 15mA, inter-distance electrodes of 1.5cm. The results revealed that this process could reduce the concentration of BOD, COD and Lead in RW. The highest removal efficiencies of 98.74% and 98.47% (COD); 82.02% and 79.12 (BOD); 90% and 83.33% (Lead), were obtained for AL-AL and AL-C electrodes respectively. From this study, it can be concluded that electrocoagulation is effective in the treatment of RW. It is recommended that Rubber producing industries could adopt this treatment method to treat their wastewater rather than disposal into the environment without treatment.</p> <p>&nbsp;</p> E. O.
