In a hypochlorination system, what is the purpose of the solution tank?

In a hypochlorination system, the solution tank serves as the reservoir for the chlorine solution that will be fed into the water for disinfection. It stores the prepared chemical (often sodium hypochlorite or calcium hypochlorite solution) so the chemical feed system can draw a controlled amount and introduce a consistent dose into the water stream. This setup ensures reliable residual chlorine levels downstream and allows proper mixing and dilution as needed before dosing. This differs from measuring pH, which is done with a pH meter or test kit; storing finished water, which occurs in storage or clearwell tanks after treatment; and housing the pump, which is part of the pumping assembly rather than the storage of the disinfectant solution.
