What is OBR in water softener?
What is OBR in water softener?
A water softener is a filtration system that works to remove high concentrations of calcium and magnesium that cause hard water. This tool is useful in determining softener resin quantity, OBR(output before regeneration), salt and water requirement during the regeneration process.
What is ionic load in DM plant?
Ionic Load : Cation load is the sum of calcium, magnesium, sodium. Anion load is the sum of Sulphate, Chloride, Nitrate, Phosphate, Fluoride, Free CO2 and Silica. In natural water, the total content of cations is quantitatively equivalent to the total anion content when SiO2 and free CO2 are not considered.
What is regeneration in DM plant?
DM Plant Regeneration The process of restoring their power or enhancing active ion concentration level is called regeneration. In this process exhausted cation and anion ions are recharged with Hydrogen (H) Hydroxyl (OH) ions.
What is capacity of ion exchange resin?
In general terms, the capacity of an ion exchange resin can be expressed as the quantity of ions that can be taken up by a specific volume of the resin. A measured quantity of caustic (NaOH) is then passed through the resin so as to totally exhaust the resin.
How is softener OBR calculated?
The softener capacity is calculated in three simple steps:
- Convert water hardness from ppm to grains per US gallon. Total Hardness (ppm) = Total Hardness (gpg) Example: 118 ppm TH = 6.9 gpg;
- Calculate softener capacity in grains.
- Calculate softener capacity in gallons.

What is demineralisation process?
Demineralization is the process of removing mineral salts from Water by using the ion exchange process. Demineralised Water is Water completely free ( or almost ) of dissolved minerals as a result of one of the following processes : Distillation.
How does a DM plant work?
In two-bed demineralization, a stream is first treated with a strong acid cation (SAC) resin that captures the dissolved cations, and releases hydrogen (H+) ions in exchange. The resulting mineral acid solution is then routed to the strong base anion (SBA) resin bed.
What is the pH of DM water?
pH value of dm water The pH value of demineralized water should be 7.0 but it is slightly acidic. Reason, the carbon dioxide dissolves in it from the air; until reaches dynamic equilibrium with the atmosphere.
How do you calculate resin capacity?
How do you calculate exchange capacity?
To determine the cation exchange capacity (CEC), calculate the milliequivalents of H, K, Mg, and Ca per 100g of soil (meq/100g soil) by using the following formulas: H, meq/100g soil = 8 (8.00 – buffer pH) K, meq/100g soil = lbs/acre extracted K ÷ 782. Mg, meq/100g soil = lbs/acre extracted Mg ÷ 240.
What is a good number for water hardness?
An acceptable level range for water hardness is going to be 100- 300 PPM depending on what city you live in and what the water treatment plant has decided on.
How is the OBR of a DM plant calculated?
DM plant OBR is calculated by knowing the following things. 1.Total ionic load; this can be found in raw water quality. “Total ionic load; this can be found in raw water quality”. FIRST, THANKS FOR ADVISING REQUIREMENT FOR OBR.
What is the difference between DM and OBR?
DM = dimineralization OBR = output between regenerations Q. We are operating DM plant of 2 streams of capacity 2740 m3OBR ( 137 m3/hr * 20 hrs ). Presently our ionic load is lower by 40% than design. We have increased the output to 3500 m3per regeneration by increasing the run length to 26 hours instead of the design 20 hours.
How to calculate the ionic load in a DM plant?
Ion Exchange / DM plant calculations 1 Total ionic load; this can be found in raw water quality. 2 Total exchange capacity of resins 3 Quantity of resin in ion exchange vessel vessel 4 Flow of water
How much water can a SBA DM plant deliver?
We are having a Ion Exchange make DM plant of rated OBR 600 m3but plant is delivering a maximum of 350-400 m3DM water in one stretch after regeneration. Either this SBA Unit SiO2goes high or the conductivity crosses the limit. Please give your comment or suggestions for improving the OBR VISHAL KUMAR
