Vaibhav,

What are you dosing and for what purpose?Your query cannot be answered if these details are not explained.

Most dosing chemicals in water generally are for the purpose of preventing corrosion, preventing inorganic scale formation and deposits, preventing fouling due to fungus / bacterial growth and for maintaining pH of the water. Many of the chemicals used for water treatment provide all or some of these treatments mentioned above and are mostly a formulation for particular combination of treatments. Also these formulation chemicals are proprietary in nature and manufactured and sold by a few select companies such as NALCO etc.

If you are going to use such a formulation chemical for water treatment then the dosing rates are also provided by the manufacturer / supplier of the particular chemical based on the analysis of the untreated water and the characteristics of the final treated water. You do not need to do your own calculations for the dosing rate and sizing the system.

Generally the dosing rates are very low and most dosing pumps have a capacity of a few liters per hour and in many cases less than a cubic meter per day.

The best way is to get in touch with your dosing chemical supplier.

Hope this helps.

Ankur
