The aim of this study is to remove the inorganic phosphate from the wastewater to control over the eutrophication and to maintain the WHO level concentration of 0.1 mg/L (MCL) using the developed heterogeneous cost-effective synthetic adsorbent iron-oxide-impregnated-crushers-waste (IOICW). In a batch study, it was found that about 80% of phosphate was eliminated within a 10 min timeframe when treated with a dosage of 10 g per liter. This occurred under room temperature conditions and at a pH level of 6.8 ± 0.3, starting with an initial concentration of 1 mg/L. Study also carried out in presence of common interferences like chloride, nitrate and sulfate. Continuous mode study, i.e., 10 cm IOICW packed column study was conducted with an up-flow rate 8 mL/min. The column was designed by the logit model to understand the break-through and bed-exhaust time with column efficiency for the practical purposes. The times for breakthrough and bed exhaustion were recorded as 3.0 h and 10.0 h, respectively. The calculated column efficiency was found to 64.707 mg/L with minimum bed depth is 8.18 cm.
