Determination of Phosphorus Removal Mechanism in Aerated and Unaerated Steel Slag Filter System as Secondary Treatment System for Textile Industrial Wastewater

Phosphorus is the element that promotes growth in plant. However, over loading of phosphorus into surfaces water leads to severe environmental problems known as eutrophication. Improper treatments removal prior discharges from industrial effluent are one contributions Textile sources surface with concentration 1-9 mg/L P. Since attentions given removing color effluent, commonly ignored wastewater treatment system. Thus, study textile conducted using steel slag system filter under aerated (ASSF) and unaerated (USSF) condition. The systemwas set up for influent pHrange 5.30-7.00 at primary treated wastewaterfor wastewaterunder Sampling was done twice a week 12 weeksand analyzed Total concentration. Activated Carbon(ACF)filterin existing also sampled compare efficiency USSFfilter shows better than ASSFfilter with46% 70%of removal.Meanwhile, ASSF 37% 66%.The adsorbate formed SEM-EDX precipitation USSF XRD.This provides promising result removal.
