Industrial Wastewaterdue to its chemical and physical contents can be the source of positive and negative effects on irrigated soil. In this study, the quality of the effluent of the Malaysian refinery was studied and its long-term effect on the soil of the green space around the plant was investigated. The results showed that the effects of the use of mentioned industrial effluent in terms of salinity, chloride, sulfate and sodium adsorption ratio are more than normal irrigation water. In terms of BOD, COD and fecal coliforms, effluent conditions are acceptable. In terms of fat, the effluent is higher than the standard. For these conditions, it is recommended to apply physical filtration from the wood chips bed in the transmission channel and physical filtration in the central control unit of the drip irrigation system. In summary, the results of this study show that the use of refinery effluent is not limited if filtration and mixing are used to qualitatively modify environmental and irrigation problems. In addition, studies of this reseach show that the time factor is effective in changing the quality of wastewater and therefore qualitative evaluation is recommended in different seasons.
