Abstract

Water pollution is a concern not only in Vietnam but also in many regions worldwide. Among various treatment strategies, biological methods using aquatic animals and plants have gained increasing attention. This study investigated the effectiveness of biological water treatment through four 10-day experimental setups: (1) control, (2) treatment with Asian clams, (3) treatment with water lettuce, and (4) treatment with both Asian clams and water lettuce. Water quality was assessed by measuring pH, total suspended solids (TSS), and dissolved oxygen (DO) at both inlet and outlet points. The results showed that clams and pistia helped maintain neutral pH levels and effectively reduced TSS concentrations (2.35%, 3.95%, and 4.48% reductions in experiments 2, 3, and 4, respectively). However, improvements in DO levels were not significant. The findings provide a foundation for selecting appropriate biological agents tailored to the specific pollution characteristics of different water sources.
