Experimental Study of Effluent Salty Wastewater Treatment from a Solar Desalination Pond

In this research, the quality of wastewater discharged into environment has been investigated. The effluent from solar desalination pond contains large amounts TDS (3.68 grams per liter) and TH (6.50 liter). Since use filter is not economical in case, three types commercial coagulants such as aluminum sulfate, ferric chloride sulfide have used study. main parameters effectiveness inorganic coagulants, ammonium chloride, which separately help to remove hardness, studied. According results, using laboratory test, 25/g sulfate coagulant best mass ratio 4 3 for auxiliary (sodium carbonate sodium hydroxide) will be ratio. Also, mixing rate 120 rpm first reactor give speed. These conditions lead 0.348 liter TDS, 0.345 0.195 calcium hardness 300 micro Siemens electrical conductivity purified sample.
