Sea salt quality good or bad From the following several aspects to identify：
- Firstly, on the appearance. Good sea salt uniform grain appearance、drying、in quicksand shape、no obvious visible impurities.
- Secondly,detection of soluble salt water velocity：The sea salt soluble in water and RO water, soluble speed fastly, the solution of water insoluble substance and all impurities, no precipitation.
Sea salt dissolution time mainly depend on the quantity of salt dissolved.
1Kg sea salt dissolved 301 Fresh water, the process of agitation 3-5 minutes completely dissolved as well.
1 tons sea salt dissolved 30 cubic water in the process of pump agitation 12 hours completely dissolved as well.
- The third aspect：Testing PH value Good sea salt PH value stability,salinity normal, no phosphate and nitrate.
