In industrial scale water softening plants, the effluent flow from re-generation process can be very significant. Under certain conditions, such as when the effluent is discharged in admixture with domestic sewage, the calcium and magnesium salts may precipitate out as hardness scale on the inside of the discharge pipe.

Each calculation is followed by an example, using this information: The water contains 118 ppm of total hardness and the softener has 6 ft 3 of resin that is regenerated using 15 lbs of salt per ft 3. The softener capacity is calculated in three simple steps: 1. Convert water hardness from ppm to grains per US gallon

Excessively hard water will nearly always have to be softened in order to protect the water treatment plant equipment and piping systems. The two primary constituents of water that determine the hardness of water are calcium and magnesium. If the concentration of these elements in the water is known, the total hardness of the water can be ...

Soda ash is used to remove chemicals that cause non-carbonate hardness. The appropriate chemical dosage for various unit processes is typically determined by lab testing, monitoring and historical experience of the plant. Once the chemical dosage is determined, the feed rate can be calculated using the typical feed rate calculation already covered:
