Evaluating Natural Materials for the Reduction of Antifoaming Phenomena in Aquatic Environments

Overview

Foam pollution significantly impacts aquatic environments, influencing factors such as pH levels, turbidity, salinity, and temperature, and disrupting aquatic life. This study aims to evaluate the effectiveness of natural materials as anti -foaming agents, with a particular focus on rice bran powder as a potential solution. Eight natural materials were tested: gardenia fruit powder, chlorella powder, sweet pumpkin powder, rice bran powder, oatmeal, ginger powder, kelp powder, and flour. Each experiment was conducted using a beaker containing 2 milliliters of foaming detergent, 150 milliliters of water, and one of the natural materials. The mixtures were shaken using a laboratory shaker for an equal duration. The results revealed a significant reduction in foa m formation in specific natural materials compared to the control group. Among these, gardenia fruit powder and rice bran powder showed equivalent effectiveness, each achieving a mean foam reduction of 195 milliliters. Both materials shared the same standard error of difference (13.463), T-statistic (19.8684), and P-value (P < 0.0025) when compared to the control group. The findings support the hypothesis, demonstrating that rice bran powder, along with gardenia fruit powder, was the most effective natural anti-foaming agent tested.
