Electrocoagulation in Textile Wastewater Treatment
No full textThe importance of clean water is a crucial concern nowadays. Since water pollution and related environmental impacts keep increasing due to industrial effluents, especially from the textile sector, this thesis explores the application of electrocoagulation (EC) for cleaner and sustainable wastewater treatment method focusing on Amaranth azo dye removal.
The experiments involved building a lab-scale EC unit with an Aluminum anode and carbon felt as a cathode to evaluate the operating conditions (initial pH, applied potential, and stirring speed). The results showed that dye removal efficiency in EC is maximum at pH 2, with 6.4 V of applied potential at 1000 rpm, where the removal was 100% in 30 mins of electrolysis time.
The study confirmed that, even if the initial pH is lower to achieve maximum efficiency, the final pH tends to be neutral, enabling the release to the environment without requiring any remediation. Also, EC offers the advantages of less sludge production without being time-consuming, while eliminating chemical additions that cause secondary pollutants. The findings support further exploration in real industrial wastewater treatment application integrated modelling approaches for efficient optimization
