Consequences of Using Wastewater for Irrigation Purposes and Finding Inexpensive Solutions to Remove its Contaminants for Reusing

Abstract

In recent years due to the lack of water resources in Egypt, remediation of wastewater become necessary. Also, the usage of low cost friendly safe for environment and easily available substances in this remediation is in demand. So, A laboratory experiment was carried out to evaluate wastewaters of five different sources for irrigation purposes and assesses activated charcoal and zeolite in removing the contaminants from these wastewaters. The activated charcoal and zeolite were added each separately at two different concentrations (1.0 and 2.0% ) Mixtures of wastewater and used natural ores were placed onto a rotary shaker at room temperature (20 ˚C), where each flask was prepared twice, the1^st flask was shaken at 200rpm for one hour, while the 2^nd flask was shaken at 200rpm for two hours. Thereafter, samples were filtered where the filtration was one day for the samples shaken for one hour only and two days for the samples shaken for two hours. The filtrate samples werechemically analyzed.The findings showed that the wastewater of Belqas and Batra agricultural drainage water, Sewage water from Station of Mansoura city, disposed of water of Aja Factory for the production of food are valid for irrigation after remediation, while industrial wastewater discharged from Sandoub Oil and Soap Factory is not suitable for agricultural purposes. Also, using zeolite and activated charcoal materials at the two different rates have a high capacity for the remediation of wastewaters, but the concentration of 2.0% was more effective in removing than 1.0%, also shaking for two hours was more effective in removing pollutants than one hour, moreover, the ability of activated charcoal in removing is more efficient  than zeolite.
