System for determining chlorine demand in water

A system for determining chlorine demand in water, the comprising:

• a reagent supply tank configured for holding a solution of hypochlorite ions in known concentration;
• a buffer tank positioned in fluid communication with the reagent supply tank;
• a first conduit disposed between the reagent supply tank and the buffer tank, the first conduit being configured for transferring the solution from the reagent supply tank into the buffer tank;
• a mixing tank positioned in fluid communication with the buffer tank;
• a second conduit disposed between the buffer tank and the mixing tank, the second conduit being configured for transferring the solution from the buffer tank into the mixing tank to form a composite solution;
• a first chlorine measuring device connected to a first tap between a water source and the mixing tank, the first chlorine measuring device being configured for measuring free chlorine in the water source;
• a pump operatively coupled to the mixing tank, the pump being configured for pumping water from the water source into the mixing tank, the first tap being disposed between the pump and the mixing tank;
• and
• a second chlorine measuring device connected to a second tap at an output of the mixing tank, the second chlorine measuring device being configured for measuring free chlorine in the composite solution.
