Everything You Need to Know About Hard Water Treatment

Dealing with hard water in the daily schedule is quite hectic and sturdy. Water is a universal solvent that naturally dissolves calcium, magnesium, iron and other minerals during rain. When the water passes over rocks and soil reserves suspend in water causing water to be hard.  Water treatment is a process by which makes hard water is made suitable for drinking and other water applications.  The primary job of water treatment/softening is to prevent precipitation and build up limescale. By water softening water, hard water scaling and contaminants of water are eliminated. To know more about hard water, follow this link “here

For eliminating hardness of water, it is very important to know what are the types of hard water and different types of water treatment.

Types of Water Hardness:

  1. Temporary hardness
  2. Permanent hardness

Temporary Hardness:

Temporary hardness can be removed by boiling water. It has a small number of bicarbonate ions present. By boiling water carbon dioxide gas is evaporated. This reaction results in the reduction of soap scum.

Permanent Hardness:

Water containing chloride or sulfate cannot be softened by boiling. This water is known as permanent hard. To soften these types of water methods like soda and ion exchange processes is needed.

Types of Water Treatments:

Water Treatments can be broadly classified into two categories:

  • Conventional water treatment/ softening
  • Softening via Equipment

Conventional Water Treatments:  

The most favorable water softening is through the ion exchange process. A synthetic plastic polymer in the form of small beads is densely packed to form an ion exchange resin. These porous resins contain billion of active ions. When the hard water containing primary minerals like calcium and magnesium flows through the resin it holds the impurities. However, hard water also consists of secondary particles of iron, manganese, and aluminum.

Sodium ions are forced into the resin bed that starts the ion exchange process. These resin beds produce safe water after de-mineralizing it.


Softening via Equipment:

Water softening equipment has two tanks a larger one has sodium and another tank for ion exchange process.  A control valve at the top is fixed to enhance water flow as gallons of water are processed through it.

The regeneration cycle begins where water flows through the valve to the tank via resin later to the collector. The water passing through resin bed holds impurities making water usable.


Cost of Water Treatment:

A water softener starts around $500 and goes to $1500 for household purpose. It depends on capacity and quality (levels of purification).

For industries with a capacity of 150000 GPD will cost around $500000 to $1.5 Million including installation and startup.

Conclusion:

A hard water treatment depends on many factors like, what is the type of hard water? Where it is to be done and what is the purpose behind it. Hence, all the aspects have to be examined while picking an accurate water softener for your home or industry.

Cost of treatment depends on how big the project is if it’s for manufacturing units a heavy system is to be installed that will cost you more and vice versa.
