Zeolite used in zeolite softening process for the treatment of hard water gets exhausted after certain time of usage but can be regenerated by flushing it with
After sometime sodium zeolite is completely converted to calcium and magnesium zeolites so reactions stop. Then, 10% brine solution is passing through these calcium and magnesium salts which regenerate back sodium permutit which we can reuse to softening of hard water.

Hard water can be softened by adding sodium carbonate (washing soda) or by passing the water through an ion-exchange column.

See lessHardness of water does not
The hardness of water does not affect the drinkability of water. The hardness of water is caused by the presence of different types of minerals like calcium and magnesium in high concentrations in it. This causes the formation of white flakes in a boiler when the hard water is boiled.

COD. The chemical oxygen demand (COD) test is commonly used to indirectly measure the amount of organic compounds in liquid waste. It is expressed in milligrams/grams per liter, which indicates the mass of oxygen consumed per liter of solution.

In drinking-water, hardness is in the range 10–500 mg of calcium carbonate per litre (3)

See lessConventional tertiary treatment is
Tertiary treatment, which is final stage of conventional treatment technique, uses advanced treatment options and it focuses for specific pollutant removal, disinfection, etc. Some of the advanced treatment techniques used for PPCPs can also be included in the tertiary treatment.
