Abstract

The biodegradability of Coconut Fatty Alcohol Sulfates (CFAS) in static, un-aerated and non-renewed set-up was monitored over a 24-hour duration test using test tanks. Water quality parameters such as pH, temperature and total dissolved solids (TDS) were measured to assess the quality of water as affected by the biodegradation of the surfactant.

Purity of the CFAS sample was confirmed to be 60.16%. The biodegradability of CFAS was monitored by measuring the surfactant concentration present in water sample using Methylene Blue Active Substance (MBAS) method with test concentrations of 0, 1.0. 3.0 and 5.0 mg/L. The amount of CFAS in the test tanks dropped to zero at the end of sampling time.

Results were statistically analyzed to determine the significance of measured variables. Based on ANOVA and DMRT, the three test concentrations and sampling period significantly affected the three water quality parameters. Addition of CFAS lowered the pH and increased TDS while temperature was found to be independent of surfactant concentration.

Values obtained for the water quality parameters fall within the Maximum Allowable Limit (MAL) set by the Department of Environment and Natural Resources (DENR) for Class C water.
