1. Ensure water fed to the softening plant is free from suspended particles, Iron, organics, oil, slime, heavy metals.
2 Regeneration of the softner plant is being done whenever the water quality detoriates, (confirm by test given below).
3 Regeneration:
3.1. Dissolve 10 kgs of commercial grade Sodium Chloride in about 60 Liters of raw water in water softner injection tank.
3.2. Back wash for 10 minutes with Raw Water
3.3 Inject the brine solution (Down flow) with the help of the Ejector.
3.4. Remove Calcium and magnesium salts formed during regeneration and excess brine by down ward flow of raw water. (Approximately 15 to 20 minutes)
3.5. Up-Rinse the softner for 15 to 20 minutes with raw water.
4. check the Quality of water by the following method.(Hardness less than 1mg/lit) following method.
Take about 100 ml of soft water and pour it into a round bottom flask. Add 1 tablet of total Hardness indicator tablets. Shake well till the tablet completely dissolves. Add 2-3drops of Ammonia Buffer solution.
If a steel blue colour without pink tinge is obtained the hardness will be less than 1mg.
If a pink colour is observed, add N/50 EDTA solution drop by drop until getting a steel blue without pink tinge.
Each drops of EDTA solution added is equivalent to 1 mg/Lit of total hardness in water.
5. Send sample to Quality Control for analysis.
