This project studies and construction of a water filter RO - spotted by RO filter consists of five sets
, including coarse filter,
carbon filter flakes. ,
filter scale carbon block
filter INLINE,
water filters and RO filtration spotted the first set
by sending water samples to determine the two examples include RO water and lye by sending detection value of calcium, magnesium. potassium, sodium, and was spotted by the RO water is 7.83 mg per liter of calcium, magnesium, potassium, 1.17 mg 0.42 mg sodium, 3.29 mg per liter. And TBN, the temperature 25 degrees, 6.57 mg
of calcium alkaline water is 5.8 milligrams per liter to 13.0 mg per liter magnesium, potassium, sodium, 4.1 mg to 4.4 mg per liter. The pH at 25 ° 9.08 milligrams per liter. The result was satisfactory in the Department of Health has defined.
