Irrigation Suitability of Treated Wastewater of Biofilteration Treatment Plant

The supervision of water resources has turned into a challenge in developing nations where the infrastructural evaluation has not kept pace with population increment and urbanization. With the concern of water shortage, the wastewater reuse is an appropriate tool in guarding the available water resources and also, it is being adopted globally and considered as a substitute water asset in a modifying agricultural environment. In the present study, therefore, the determination of the appropriateness of Bio-filtration Treatment Plant treated wastewater for irrigation was assessed with respect to the irrigation water quality guidelines. Additionally, to categorize water quality and to assess its suitability for irrigation practices, Sodium Absorption Ratio (SAR), Electrical Conductivity (EC) and Residual Sodium Carbonate (RSC) were analyzed and calculated experimentally as (0.006), (897.824 µS/cm) and (−12.673 me/l) respectively. The high salinity and low sodium water results illustrate that the treated effluent is satisfactory for irrigation on almost all type of crops having good salt tolerance capacity and soils having controlled drainage without the risk of exchangeable sodium. RSC value was negative for all collected samples, demonstrating that there was no possibility of precipitation of calcium and magnesium. Furthermore, the data indicates that with decent management and regular quality control check, the treated effluent of STP can be classified with few exceptions as suitable for irrigation use. Principal component Analysis (PCA) was used to determine the correlation between the analyzed parameters and showed a high degree of correlation between these parameters.
