Abstract:
A multi-process water treatment system comprising:a manifold; a plurality of output branches in the manifold; a disinfectant source adapted to supply a substantially continuous flow of disinfectant to the manifold; a plurality of water treatment processes fluidly coupled to the manifold; a plurality of sensor means, each sensor means coupled to a water treatment process, the sensor means adapted to communicate data representative of the concentration of the disinfectant present in each water treatment process; a central controller means adapted to receive data from the plurality of sensor means; a disinfectant discharge conduit; a three-way diverting valve disposed in fluid communication between each branch of the manifold and each water treatment process, the valve having a first position wherein disinfectant is delivered to the water treatment process and a second position wherein disinfectant is delivered to the disinfectant discharge conduit; whereby the three-way diverting valve for a first process is switched by the central controller means from the first position to the second position responsive to data received from the sensor means indicating a predetermined disinfectant concentration has been achieved in the first process, the disinfectant originally supplied to the first process is then sent to the disinfectant discharge conduit thereby maintaining a consistent pressure in the system for disinfectant delivery to other processes.
