Brackish Water&Wastewater Analysis and Blending
Under Mediss Project funded by the EU Activities aiming to fix the most suitable blending ratio of treated wastewater, brackish water and fresh water to be used in irrigation is undergoing intensive site and laboratory efforts by PWEG.
PWEG has been testing the quality of fresh, brackish and blended water; the results are disseminated to all farmers in the Jordan Valley to help them use the optimal ratio of blended water to be used in irrigation.
Several tests have been made such as Nitrite, Nitrate, Chloride, HCO3, EC, Total dissolved solids (TDS), pH, temperature and Chemical oxygen demand (COD), the following table shows the results of these testes.
