Performance of slow sand filter reactor using geotextile for reducing total n and phosphate

Abstract

Water pollution that occurs is mostly caused by industrial and domestic waste. One of the consequences of polluted water is the increase in total N and Phosphate which causes malfunction of animals and humans. This is a problem that needs attention to protect our life from the dangers of environmental pollution. Slow Sand Filter is an easy and inexpensive raw water treatment solution. The raw water used in this research is the Dungus Sidoarjo river. The acclimatization process was carried out for 14 days. Sand and gravel were used as filter media with a geotextile thickness of 0.2 and 4 cm. The sample is taken on the first, sixth, and twelfth days. The best reactor for reducing Total N and Phosphate is a reactor with a geotextile thickness of 0.2 cm (D2) on the first day of effluent taking, which is 84.5%, and a reactor with a thickness of 4 cm on the sixth day of effluent taking, which is 77%. The results of the One Way ANOVA test with a standard error (α) of 0.05 stated that there was no significant difference in the treatment of each reactor in reducing total N and Phosphate.
