Chlorination kits are equipment that primarily dose chlorine into water based on the water volume measured by a meter with pulse generator. They can be used for water chlorination to oxidize iron, manganese, ammonium, etc., or to introduce a dose ensuring protection against bacterial growth. These kits can also be used in other applications involving precise dosing based on a specific volume, such as pH adjustment, coagulant dosing, fertilization liquids, etc. Precise dosing of chlorine or other solutions is performed by the dosing pump following a pulse received from the meter pre-equipped to transmit pulses after a certain volume of fluid measured by the meter has passed. Thus, the actuating element in this system is the dosing pump and the control element is the pulse-generating meter. The dosing pump performs the dosing operation according to the user’s specific settings.
