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