1 Powell Skid Mounted Batch Bleach System 1

2 1 Bleach Production Overview Powell Skid Mounted Batch System Shown below are the steps needed to prepare a batch of bleach using the Powell Skid Mounted Batch Bleach System. a) The Powell Batch Bleach System operates using a manually controlled tank level system: Note: The batch tank has volume markers molded into the side of the tank. i) The proper amount of soft water is added to the batch tank. (1) This can be from a pressurized city water supply, piped directly into the top of the batch tank by opening the city water valve. (2) This can be water from a storage tank pumped by starting and stopping an optional water pump and piped directly into the top of the tank. b) Recycle pump is started; water circulates through heat exchanger & filter housings and back to batch tank. i) Operated using a purchaser supplied motor starter & controls. c) Cooling water pump is started; cooling water circulates to heat exchanger and back to cooling tower. i) Operated using a purchaser supplied motor starter & controls. d) Cooling tower fan is started. i) Operated using a purchaser supplied motor starter & controls. e) The proper amount of 50% caustic is added to the batch tank. i) This can be caustic from a tote container or barrel, connected to a manual service valve in the recycle pump suction line. ii) This can be caustic from a storage tank pumped by starting and stopping an optional caustic pump and piped directly into the top of the tank. iii) The temperature of the dilute caustic is measured and displayed on control panel screen display. iv) The dilute caustic is sampled and tested by the operator for proper strength. (a) The strength is then adjusted by adding more caustic or water as needed and then re-tested by the operator for proper strength. f) Once the diluted caustic is at the proper strength, it will be chlorinated over a three to five hour period of time, depending upon the strength of bleach being produced. i) The manual chlorine throttling valve is closed. ii) The automatic valve at the chlorine container is opened using the control on the screen display. iii) The manual chlorine throttling valve is slowly opened to introduce chlorine into the sparging tube of the batch bleach system. (1) Chlorination is monitored using Powell ORP electrodes (2) Chlorination set point and current ORP reading is shown on the screen display g) Batch Alarms: i) Alarms are provided to indicate the following conditions (1) High primary ORP reading 2

3 (2) High secondary ORP reading (Closes the chlorine supply block valve) (3) High dilution temperature (Closes the chlorine supply block valve, which will automatically re-open once the batch has cooled below the alarm set point) (4) High tank level indication (5) Low tank level indication (6) High or low pump flow h) Batch Cooling: i) During the caustic dilution (and chlorination) process, a portion of the solution is circulated through the heat exchanger. ii) In addition to removing heat of reaction, the heat exchanger serves as an excellent mixer, ensuring the caustic and water are thoroughly mixed. i) Batch Filtration: i) The remainder of the solution passes through two filter housings. The nominal filter bags remove suspended solids from the solution. This prevents the build up of material from settling in the recycle tank and affecting the operation of valves, pump, piping, heat exchanger and improves product quality. j) Batch Finishing: i) The chlorination process will be manually slowed down by closing the manual chlorine valve. ii) Once the batch has reached the End Point as indicated by the ORP electrodes reading on the screen display, the manual chlorine valve will be closed. iii) The finished product should be circulated an additional twenty to thirty minutes to reduce the temperature and improve the filtration. k) Batch Transfer: i) Changing the position of manual valves will allow the bleach from the batch tank to be emptied. (1) The finished bleach is pumped from the batch system through a third filter housing with an absolute filter bag that further improves product quality. (2) Care must be taken to avoid running the recycle pump dry, which will over heat the pump and cause damage. (a) The pump is equipped with a power monitor to help prevent damage from dry running the pump. 3
