I think the one-time investment and stability of using a metering pump are better than that of a high-level tank.
Ferric chloride uses a metering pump, and others can use a high-level tank.
My company uses high-level slots, and the effect is pretty good.
I personally think that to calculate in the long run and comprehensively consider the energy consumption of both, the metering pump can meter； High slot for easier adjustment.
All can be used. I personally think that the high-level tank is better. If the device is large, a centrifugal pump can be used directly. If the metering pump for ferric chloride is used, the metering pump diaphragm is often broken, and the maintenance rate is high.
It is better to use high-level slots. Our company uses high-level slots.
Our unit uses a high-level tank, and the amount added is controlled by a flow meter. The quality of the brine is relatively stable.
We all use high-level tanks here, but sodium hydroxide and sodium hypochlorite are no longer used.
It still depends on the device capabilities! If the amount of the refined agent is large, I personally think that it can be added directly with a centrifugal pump and a regulating valve. If the amount of the refined agent is small, a metering pump can be used, or a high-level tank adding method can be used. I personally think that the high-level tank method is more stable in control, and it is also convenient for batching and switching, which facilitates production control.
We all use high-level tanks here, but we do not add sodium hydroxide and sodium hypochlorite.
We use a high-level tank, but we don’t add subsodium.
Our company also uses metering pumps. I personally think that high-level tanks are more accurate.
