Physico-chemical factors of solar salt farms water in the coastal area of Cox’s Bazar, Bangladesh
Physico-chemical factors of water at different gradient of the salt production pans (reservoir, condenser and crystallizer) of the coastal area in Cox’s Bazar were studied.Analyses of water temperature at different gradient of salt pans show almost similar values (31°C-32°C). The pH values varied from 4.9 to 7.4. The acidic pH values were recorded in Chakaria Sundarban area. Salinity ranged from 30.03‰ to 330.52‰, lowest salinity was found in reservoir pan and highest in crystallizer pan. Electric conductivity values fluctuated between 9.60 and 336.00 mmhos/cm and its values gradually increase from reservoir to crystallizer pans. Total hardness, Ca, Mg and HCO3 varied from 8000 to 213600 mg/l; 2987 to 106300 mg/l, 5013 to 107300 mg/l and 36.6 to 146.4 mg/l respectively and their values were always found to be Reservoir < Condenser< Crystallizer. Alkalinity ranged from 50-570 ppm, the lowest values were recorded inreservoir pan and highest were found in crystallizer. Usually higher concentration of K was obtained in crystallizer pan and the highest value (15.2g/l) was recorded at Moheskhali sampling area.
