Sigit Kurniawan, a researcher from Politeknik Jambi’s Department of Electronic Engineering, has shed light on a pressing challenge at the intersection of water treatment and coastal aquaculture. His review, published in the *Journal of King Saud University: Engineering Sciences* (formerly *Journal of King Saud University: Engineering Sciences*), examines greywater treatment technologies—physicochemical, biological, and advanced oxidation processes (AOPs)—and their role in removing organic, nutrient, and surfactant pollutants. The findings could have far-reaching implications for coastal industries, particularly those reliant on clean water for aquaculture.
Kurniawan’s work is particularly timely as coastal aquaculture faces increasing pressure to meet sustainability and safety standards. Greywater, which originates from domestic sources like sinks, showers, and washing machines, often contains residues that can disrupt aquatic ecosystems if discharged untreated. Traditional treatment methods have struggled with efficiency and scalability, but Kurniawan’s analysis suggests that AOPs—processes that use chemical reactions to break down pollutants—could offer a more adaptable solution.
“AOPs have a huge potential in greywater treatment because they are low-cost to develop, easy to install, and can be deployed on a small scale,” Kurniawan notes. This flexibility is critical for coastal operations where infrastructure may be limited or where space constraints prevent large-scale treatment facilities. Moreover, AOPs can be combined with other methods to enhance performance, creating hybrid systems that adapt to specific pollutant profiles.
The commercial implications for the energy sector are notable. Coastal aquaculture operations, from shrimp farms to algae cultivation, require consistent water quality to thrive. Untreated greywater discharge can lead to regulatory fines, operational disruptions, and reputational damage. By adopting more efficient greywater treatment technologies, aquaculture businesses could reduce their environmental footprint while improving compliance with water quality regulations.
Kurniawan’s review also highlights the need for further innovation in greywater treatment. While AOPs show promise, their real-world application will depend on factors like energy efficiency, cost-effectiveness, and integration with existing systems. The research underscores the importance of interdisciplinary collaboration—bringing together engineers, environmental scientists, and industry stakeholders—to develop scalable solutions.
As coastal industries grapple with water scarcity and pollution, Kurniawan’s work provides a roadmap for smarter, more sustainable water management. The next steps will likely involve pilot projects and partnerships to test these technologies in real-world conditions. For the energy sector, this could mean new opportunities in water treatment innovation, particularly in regions where aquaculture and coastal development intersect.
