Considering the population increase in the cities and also the increase of per capita water consumption in
these societies, the use of treated effluents for the green area irrigation has been taken into consideration .
Human ever-increasing needs to green area in municipal societies and on the other hand the limitations in
water supplies cause a new review in wastewater reuse. Also making use of treated effluents in irrigation
has some limitations including clogging of the soil porosities, increasing of the chemicals and toxic
substances to plants and increasing the probability of groundwater pollution. In this research, considering
the indicators using recognition of the effluent י s quality, at the first stage compound samples of domestic
wastewater treatment effluents of Zamyad Factory were taken. The samples were tested from the
viewpoint of quality. Results showed that the indicator of Sodium Adsorption Ratio, Sodium Percentage,
amounts of chloride, and electrical conductivity comparing to Food and Agriculture Organization and
Department of the Environment of Iran standards were higher than the standard levels. Also parameters
such as TDS, TSS, BOD, COD, anions and cations were in standard levels. Results also showed that the
increase of some of the undesirable parameters was not related to the operation of wastewater treatment
plant. Therefore, in order to make the standard effluent, different methods may be proposed and the most
practical and economical one is dilution by using 50% mixing with raw water.
