| Abstract | ||||
| This study aimed to evaluate the effectiveness of low-cost adsorbent materials in filters for wastewater treatment at the Zenin Wastewater Treatment Plant in Giza, Egypt. Various thicknesses of sawdust were used as the adsorbent material.The concentrations of water parameters obtained were compared with the Egyptian specifications for the use of treated wastewater in irrigation, and the suitability of the wastewater parameters was confirmed. The Multimedia filter process effectively removes contaminants such as Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), pH, ammonia, nitrite, nitrate, and nickel from the effluent. After the primary sedimentation tank using 40 cm sawdust as low cost adsorbent, the BOD, COD, TSS, ammonia ,NO3, oil and greases and NI reduce from 226.8 mg/l, 353.81mg/l, 376 mg/l, 18 mg/l, 0.5 mg/l, 30 mg/l, 0 mg/l , to 59 mg/l ,98 mg/l , 41 mg/l,8.1 mg/l, 0 mg/l, 7 mg/l, 0 mg/l with removal efficiency 73.98%,72.3% , 89.1% , 55% , 100 %,76.67 % witch is matching the Egyptian specifications for water intended for irrigation purposes grade C . We increase the depth from 40 cm to 80 cm to improve the proprieties of treated wastewater for irrigation from grade c to grade B. the BOD, COD, TSS reduce from 132 mg/l, 220 mg/l, 380 mg/l to 28 mg/l ,41 mg/l , 23 mg/l, with removal efficiency 78.78%,94% , 93.94% . The Low cost adsorbents have good act in the treatment system. Hence this technology is Eco-friendly and cost effective. | ||||
