Assessment of the Efficacy of Shrimp Powder as a Coagulant in Wastewater Treatment

This study evaluates the efficacy of shrimp shell powder as a coagulant in wastewater treatment, specifically targeting batik effluent. The primary aim is to compare the performance of shrimp shell powder to traditional alum in reducing key parameters such as Turbidity, Total Suspended Solids (TSS), turbidity, and color (pt-co) levels. The shrimp shells were rinsed, air dried, grounded. Jar tests were performed, and the effectiveness of coagulation tests was compared to the use of alum. In comparison to using shrimp shells powder at the prescribed dose of 25g of shrimp shell powder in milliliters of the effluent provided outstanding results (though none of the mixture gives a clear water) and alum at 20g. The effectiveness of shrimp powder and alum reduced turbidity by 37.22% and 44.49%, TSS by 25.35% and 37.98%, color 14.14% and 36.13% respectively. In contrast to alum, the shrimp shell powder increases the pH due to the presence of alkaline elements (Calcium 45.0 wt%, Magnesium 15.3 wt%, and sodium 2.0wt%) and also increased the electrical conductivity which reduced the removal efficiency by -1.30% because of the presence of high Calcium content (45.0 wt%) Calcium ions have a high charge density, making them effective at carrying electrical charge. Experimental results indicate that shrimp shell powder effectively reduces these parameters, showcasing its potential as an eco-friendly and sustainable alternative to conventional/traditional coagulants. According to the results, shrimp shell powder works similarly to alum and provides a workable way to lessen the environmental impact of water treatment procedures. Moreover, the utilization of shrimp shell powder might help waste be valued, transforming a byproduct of the seafood sector into a good resource. This research paves the way for further studies on optimizing the use of shrimp shell powder in large-scale water treatment applications, highlighting its promise in sustainable and effective wastewater management
