Abstract
SUMMARY :Treating wastewater by using inorganic and organic materials. Treating wastewater by using inorganic and organic materials. The aims of this study are :- 1 -Alleviating the hazard of heavy elements. 2- Treating the wastewater for improving the quality by using new types of material such as organic and inorganic materialsand reuse for irrigation. The present study was postulated to investigate treatment ofwastewater with inorganic and organic materials to reduce pollutants in this water.Five sources of agriculture and industrial drainage water were collected from different locations .The two sources of the wastewaters were: 1-Agricultural drainage wastewaters were collected from (Sherbien–Mietghamer-El-Mansoura (, 2- Industrial wastewater samples collected from {Delta company of fertilizers and chemicals (Talkha) and Food factory (Aga)}.The treating materials were, organic materials (Sawdust and compost)and inorganic materials (gypsum, phosphate rock, bentonite and coal). Three weights (0.5, 1, 1.5 g) of every material was prepared which was gradually added to 100 ml water then it was stirred by mechanical shaker for (30, 60, 90 minute) and samples were left for (1, 2, 3 days) and then the estimations were made before and after treating. The obtained results indicated that : 1. Effect of using gypsum, phosphate rock, bentonite, sawdust, compost and coal for treating agricultural drainage waste water sample at different locations : - The pH, EC, TSS, HCO3, Ca, Mg, N, P and K , CL, SO4, Na, K+, B, RSC, SAR and PS was decreased with remediates materials. - Using three concentrations of remediates materials and three connection times. It was found generally that as concentration of remediates materials increased as concentration of pollutants decreased where 1.5 >1 > 0.5%. - Also, as connection time increased as concentration of pollutants decreased where shaking 1.5 hour for 3 days >1 hour for 2 days > 0.5 hour for 1day. - where as a result of ability of this materials to remove apart of these pollutants and cleaning this wastewater to be more quality to use it after remediation in agricultural sector as irrigation water and to face the gap between our irrigation resources and our needs of water to irrigate our arable lands. This effect of remediates materials can be attributed to possibility as adsorbed materials to adsorb apart of these pollutants on its surfaces. - It can be concluded that bentonite as inorganic materials andsawdust as organic materials were better than other materials in remediation of these wastewaters. 2. Removal efficiency percentage of gypsum phosphate rock, bentonite, sawdust, compost and coal at three concentration and at three shakingconnection times at different locations : - The removal efficiency percentage of both organic and inorganic materials as remediation materials with three concentrationsand three shaking and connection times of remediation materials for each type of wastewaters used in this study. - Generally, it can be noticed that bentonite as inorganic materials and sawdust as organic materials were more effective in removing the pollutants from agricultural and industrial wastewaters compared to other materials. - Concerning concentration of adsorbent material, it was observed that using remediation materials at high concentration i, e 1.5 % was better than the low concentration 0.5% in removing all parameters studied in these wastewaters taken from different locations. The highest values of removal efficiency percentage were obtained with 1.5 % concentration, while the lowest values were resulted from 0.5%. - Taking in consideration the time of shaking and connection for studied wastewaters samples under study, it was shown that as shaking time increased as pollutants content decreased, It may be due to increase of exchange time which help in more adsorption for studied component in these wastewaters. - It was also noticed that removal efficiency percentage were higher with industrial wastewaters compared to agricultural drainage wastewaters due to high contents of pollutants in industrial wastewaters than agricultural drainage wastewaters.
