Hi,
If I understood your query well, I think during regeneration acid and caustic addition should be stopped when the H+ and OH- would be appeared in the outlets respectively...

Hi ,
On top of what Fallah explained , I would consider to contact the supplier of resins who should tell you the quantity of Acid or alkali to introduce per m3 of resin , this based on the strength of the chemicals .
The resource attached should give you clues about the monitoring of the process .

Dear Fallah and Breizh
I checked our resin supplier brochure, it says that the regenerant flow should be 3-18 m3/hm2.I couldn't understand this unit please explain

sarathkumar,
In fact, it is volumetric flux (not to be confused with volumetric flow rate) i.e. the rate of volumetric flow across a unit area of the total cross sectional area of the bed:
cubic meters/(1 hour*1 square meter)
