CHLORCEHCO has participated in a project in Puerto Rico. This project requires two NaOCl generator system of 300 PPD each. Fresh water from the facility is used the to produce Sodium Hypochlorite at the concentration of 04% to 0.8%. Since, fresh water is used, Water softener is required with the system.
The block diagram of the system is shown below:
The description of the On-Site Sodium Hypochlorite Generator System is shown below:
- Two 300 PPD systems with two brine tanks, two storage tanks and eight dosing pumps are required.
- Two rectifiers are used for the two systems.
- One PLC is required to control the two rectifiers.
- The output voltage and output current limit can be adjusted by manual potentiometers inside the rectifier.
- The output voltage and output current data are sensed by the PLC.
- Two ultrasonic level sensors are used to the detect the level of Sodium Hypochlorite inside the two storage tanks. The two sensors are wired to a common controller unit.
- Eight dosing pumps supply sodium hypochlorite solution to eight injection quills. Peristaltic pumps are used per recommendation by the customer. Flow can be increased or decreased manually with the potentiometer on the pump. Pump will shut down if a leak is detected inside the pump.
- The peristaltic pumps are connected to a VFD which can be controlled from minimum to maximum flow with the potentiometer. The peristaltic pumps can be turned ON and OFF with the PLC control or manually at the pump. If the pump shuts down due to a malfunction, the PLC will be alerted. Change of flow rate of the pump is not sensed nor reported.
