RO System 2000LPH Commissioning Test video
The RO System 2000LPH is for drinking water purpose application, the input raw water underground well water.
2 sets of RO System 2000LPH Commissioning Test video
With the treatment process: Dosing system——-Reaction Tank (Aeration)——Sedimentation Tank——PH Adjust——-Silicon Sand Filter—–Activated Carbon Filter—–Softener——-Cartridge Filter——–RO System——-UV Disinfection Because the input raw water has high percentage of CaCO3.

Water described as “hard” contains high amounts of calcium and magnesium, which are naturally found in the Earth’s crust. Total hardness is the sum of the calcium and magnesium concentrations, both expressed as calcium carbonate, in milligrams per liter (mg/L). You can determine your water’s hardness based on these concentrations of calcium carbonate.
Table 1 Hardness of Water
| Water Hardness (mg/l CaCO 3 ) | |
| Soft | up to 100 |
| Slightly hard | 100 -150 |
| Moderately hard | 150 – 200 |
| Hard | 200 – 300 |
| Very hard | More than 300 |
Hard water can cause scale on reverse osmosis treatment membranes and ultraviolet light bulbs, which can make treatment less effective. membrane manufacturers will often specify what the maximum hardness concentration can be, but the industry rule of thumb is that hardness should not exceed 120 to 170 mg/L.
