This project studies and construction of a water filter RO - spotted by a machine comprising a filter Ro 5 sets include input filter, filter crystallized carbon, filter scale carbon block filter INLINE, filter Osmosis Water. and filter spotted the first set
by sending water samples to determine the two samples including water, Ro and lye by sending detection value of calcium, magnesium, potassium, sodium and alkalinity in the water Ro valuable substances. 7.83 mg 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 is satisfactory, the pipeline was laid in the Department of Health.
