The Fix

The solution to the problem is to get rid of the calcium and magnesium. While there are chemical treatments that do this, the most popular answer is a water softener.

The typical water softener is a mechanical appliance that's plumbed into your home's water supply system. All water softeners use the same operating principle: They trade the minerals for something else, in most cases sodium. The process is called ion exchange.

The heart of a water softener is a mineral tank. It's filled with small polystyrene beads, also known as resin or zeolite. The beads carry a negative charge.

Calcium and magnesium in water both carry positive charges. This means that these minerals will cling to the beads as the hard water passes through the mineral tank. Sodium ions also have positive charges, albeit not as strong as the charge on the calcium and magnesium. When a very strong brine solution is flushed through a tank that has beads already saturated with calcium and magnesium, the sheer volume of the sodium ions is enough to drive the calcium and magnesium ions off the beads. Water softeners have a separate brine tank that uses common salt to create this brine solution.

In normal operation, hard water moves into the mineral tank and the calcium and magnesium ions move to the beads, replacing sodium ions. The sodium ions go into the water. Once the beads are saturated with calcium and magnesium, the unit enters a 3-phase regenerating cycle. First, the backwash phase reverses water flow to flush dirt out of the tank. In the recharge phase, the concentrated sodium-rich salt solution is carried from the brine tank through the mineral tank. The sodium collects on the beads, replacing the calcium and magnesium, which go down the drain. Once this phase is over, the mineral tank is flushed of excess brine and the brine tank is refilled.

Descaling Of Boilers

Scale and corrosion deposits of boilers results a loss of energy and heat transfer efficiency. A scale formation can also results in dangerous overheating and risk of failure and even explosion.

Procedure for Descaling of Boiler Through Soaking Method :

  • Open the Hand Holes and Mud Holes and Water Wash all the sludge present at the bottom Side of the boiler.
  • Close all Hand Holes and bottom bonnet fill water 3 inches above the tube level. See that you fill raw water having a pH of 7.
  • Add Chemical minimum 10% concentration of total water holding or depending upon the thickness of scale.
  • Close the top bonnet and steam vent and fire the Boiler to keep the Boiler on 25% of the Working pressure for a period of 8 to 12 hours, remove the air inside the boiler through the air Vent and close the air vent once the steam starts coming out.
  • Check the condition of tubes and accordingly keep the Boiler at 10% or 25% working pressure.
  • After 12 hours open the steam vent and air vent and let out the steam, then add cold water and let out hot water and cool the Boiler.
  • Open all the hand holes and mud holes and do the mechanical cleaning wherever it is possible.
  • Chemical will loosen the bonding of the scale with metal and will not totally remove the scales 60-70% job will be done by the Chemical.
  • 30-40% of the job will be done by the mechanical cleaning with our people.
