The produced water was analyzed for pH, salinity using WalkLab TI9000 pH meter (Singapore) and Consort C933 electrochemical analyser (Belgium)respectively. Also, the concentration of soluble elements consist of sulfate, nitrate andferrous were determined using APHA-AWWA (2005), Ion Selective Electrode andAWWA: 2005 (ICP-OES) method respectively by Science and Technology ServiceCenter, Faculty of Science, Chiang Mai University, Chiang Mai, Thailand. In addition,the redox potential was analyzed using Hanna H1 9125 pH/ORP meter (USA).
