Gamble III (GIII) De-Ionized Water System Requirements

J.W. Schumer, A.M. Culver NRL Code 6770

With assistance from:

R.L. Cairns, D.J. Watkins, P.L. DeWitt

SCOPE OF WORK:

1. Provide complete system costing with and without installation of piping, water storage, and a pure Deionized (DI) Water Generating System including the Pretreatment Water Filtration and Conditioning Equipment, Reverse Osmosis Membrane System, Deionization Equipment, Distribution Pumping Equipment and Advanced programmable Logic System Controls with programs that will provide completely automated system functionality, continuous dashboard style display of all performance values, reactive alarm handling for minimal Operator involvement, and mirrored Operator system control in multiple rooms.

This includes system performance data logging for after-the-fact verification of continuous water quality, flow, pressure, etc. and be capable of communication with Ignition software by Inductive Automation, an Ethernet based Facility Automation System, to meet the requirements set forth in this proposed specification document.

2. The Gamble III machine requires a liquid electrical insulator to be easily loaded into the process equipment. Absolutely pure Deionized Water provides an ideal medium to be used as an insulator in this application. The system needs to reliably produce very high-quality water that is devoid of ionic, particulate, transformer oil, and organic contamination which is ideal for use as an insulator. The DI Water is easily filled into the machine and can be evacuated from the machine when required to either refresh the water quality or when servicing of the machine is required.

3. The system shall include Hydrocarbon Adsorption of the evacuated water to remove transformer oil that may emanate from the machine and become entrained in the evacuated DI Water. Source Water for the DI water Generating System shall be non-potable chlorinated municipal water. The system is designed to purify the source feed water to provide a highly resistive liquid medium in the Gamble III machine.

4. The Deionized Water Production equipment shall be completely factory assembled on a single skid or on multiple interlocking skids as convenient for assembly and shipping. The system requires reduced field preparation and installation using a forklift. The mixed bed resin bottles are to be located on the provided concrete slab floor of NRL Building 256 Room 153, easily removable from the system using CPVC unions, and easily accessible for bottle-cart change-out. The DI-Water filtration system skid/s will also be located on a provided monolithic concrete pad at ground level in Building 256 Room 153 approximately 300-linear-feet from the Gamble III machine which is in another room (NRL Building 256 Room 152) also at ground level on a monolithic concrete pad floor. The approximate 600-linear-feet of 3-inch CPVC in/out piping and air compressor piping will have to go through an 8-foot-thick concrete wall which has a pre-drilled 12-inch diameter hole, up to a height of 17-feet, back down to ground level, and around two corners to tie into the machine using 3-inch CPVC unions, 3-inch CPVC ANSI flanges, and 3-inch NPT CPVC fittings. The in/out plumbing and electrical conduit feeds for the main system skid/s shall be installed on the floor over to the East and South walls of Room 153 at a height of no more than 1-foot so the system is accessible on all sides. The system will require two 300gpm variable frequency drive transfer pumps, one in Room 152 and one in Room 153, to pump the DI- Water over a wall to/from the machine, see figures 1 and 2. The machine will require controlled valves for the in/outs per the schematic on the last page of this document.

Figure 2 – Gamble III Facility Isometric View: Showing the overall DI-Water system configuration, heights, and piping on JBAB in NRL Building 256 Room 152 and Room 153.

5. The Deionized Water Production equipment will have on-site storage in Room 153 via a main 10,000-gallon storage tank for storing DI-Water and/or polishing the water via a kidney loop to the main DI-water system. The system will also have a second smaller 275- 300-gallon buffer tank/tote for evaluating and processing DI-water that has been potentially contaminated with oil or particulate during a catastrophic event in the machine where large amounts of particulate and/or transformer oil are introduced into the DI-Water. This smaller processing tank provides a location to send the potentially very dirty water to for evaluation and inspection. This process will be done manually and may require the DI-Water from the machine to be inspected a few 100-gallons at a time. From the smaller tank/tote the DI-water can be either cleaned and/or put back into the main DI-Water storage tank, disposed of, or forklifted to an on-site oil purification system for transformer oil reclamation.

6. An onsite visit scheduled with the NRL team, see Figure-3, is mandatory for all potential manufacturer vendors, prime bidders, or general contractors prior to submission of bid to inspect the installation site requirements and to confirm acceptability of the provided space, power, supply water, and sewer utilities. Any vendors, bidders, contractors (including sub-contractors) installation personnel must be U.S. Citizens in order to access NRL and JBAB.

DEIONIZED WATER PRODUCTION AND DELIVERY PROCESS DESCRIPTION:

This system is designed to produce high purity water and is to be assembled from carefully selected water treatment technologies for the most efficient and cost effective operation available. This system is capable of operating on a wide variety of source water chemistries and will be capable of storing 10,000 gallons of purified water. Please refer to notes in this document regarding feed water and deionized water quality requirements. This system is composed of components for non-potable city water conditioning and filtration, reverse osmosis membrane purification, electronic deionization, water storage, water distribution and delivery pumping, ultraviolet sterilization and total organic carbon (TOC) reduction, ion-exchange deionization (DI) and particulate removal with micro-filtration, and de-gassing. The pretreatment equipment conditions, filters, and removes the dissolved salts from ordinary tap water. This pretreated water is then stored, further deionized, sterilized, filtered a final time, degassed, and continuously circulated from the storage tank. The finished water is available under pressure for supply to the machine and then returned to the polishing equipment and/or storage tank under pressure. Please refer to the following Process Sequence and schematic at the end of this document for the DI-water system design.

DI WATER PRODUCTION AND DELIVERY PROCESS SEQUENCE:

1. NOTE: The following sequence is the methodology and architecture of the design.

2. The System is supplied with chlorinated municipal non-potable tap water.

3. The raw feed water is first filtered by a permanent media, self-cleaning Media Filter. The Media

Filter removes relatively large debris and finer particulate material from the source water to keep downstream equipment clean and to reduce any loading caused by source water particulate material on the subsequent filtration and purification stages of the DI Water generation process. The Media Filter automatically performs a backwash cycle to flush away any trapped particulate material. During Media Filter backwash, the Reverse Osmosis (RO) System is temporarily prevented from operating and then automatically enabled once the backwash cycle is completed.

4. The filtered water is then conditioned by the activated carbon filter. The carbon filter removes oxidizers, such as chlorine, and reduces organic molecules present in the source water.

Chlorine, added to municipal water to help eliminate bacteria, is not tolerated by the reverse osmosis water purification membranes and cannot be allowed to pass into the reverse osmosis system. The activated carbon filter automatically performs a backwash cycle to reclassify the carbon filtration media and to flush away any trapped particulate material. During Carbon Filter backwash, the Reverse Osmosis System is temporarily prevented from operating and then automatically enabled once the backwash cycle is completed.

5. The carbon filtered water then flows through a Duplex automatic ion exchange water softener.

The water softener continuously removes hardness ions (calcium, magnesium, iron) from the source water to protect the downstream reverse osmosis membranes from mineral deposit fouling. Hardness ions can reduce the life of the membranes and reduce the operational efficiency of the reverse osmosis system. The water softener media needs to be periodically flushed with a sodium chloride solution to remove the hardness ions it has collected during service. This process is called regeneration. Regeneration is performed automatically by the water softener according to the amount of raw feed water used by the system. The Reverse Osmosis System is temporarily prevented from operating and then automatically enabled once the backwash cycle is completed. All that is required for effective Water Softener operation is that an adequate level of water softener crystal salt is maintained in the water softener’s brine production tank for use by the Water Softener during regeneration.

6. The conditioned water then flows through a 1 micron rated replaceable cartridge filter to remove fine particles that could clog the reverse osmosis membrane.

7. The conditioned and filtered water is then pumped to the operating pressure of the reverse osmosis membrane. At 150 – 225 psi, the membrane separates the dissolved ions (salts and minerals) and organic molecules from the pure water, flushing these contaminants to waste and sending the purified water to the water storage tank or the process equipment. The reverse osmosis membrane is typically capable of consistently removing at least 98% of the dissolved solids from the source water. The reverse osmosis system is activated and deactivated according to a set of level switch controls located in the pure water storage tank.

8. Trace ions remaining in the RO purified water are very efficiently and cost effectively removed at 98-99.6% contaminate rejection efficiency by in-line electronic deionization (EDI) then passed through a series and parallel arrangement of four deionization resin-beds to create polished deionized water flowing to the Pure Water Storage Tank. The system up to this point is referred to as the pretreatment kidney loop that provides high purity water at the rate of the city water supply to save time and provide redundancy incase the second kidney/filtration-loop of the main system skid becomes contaminated.

9. When there is sufficient water volume in the pure water storage tank, the Deionized Water

Delivery Pump can be activated, Purified water is then pumped from the pure water storage tank by the Delivery Pump and flows the water through the second kidney/filtration-loop purification polishing stages and is eventually delivered to the Gamble III machine or returned back to the DI Water Storage Tank via CPVC piping as a filtration/kidney loop.

10. One step in the purification polishing stage is that the water flows through a high intensity, low wavelength ultraviolet sterilizer which helps to control bacteria growth in the pure water and reduces organic content of the purified water through photo-oxidation.

11. Another step in the purification polishing stage is that the deionized water flows through Mixed

Bed Ion Exchange Deionization Modules (DI Modules or resin beds) to ensure that the deionized water is free of ions and that carbon dioxide is continuously extracted from the purified water before being delivered to the Gamble III machine. DI Modules are essential in ensuring that the delivered water is at the highest resistivity to create an ideal liquid insulator within the machine.

12. The deionized water then flows through a Micro-Filter unit, equipped with 1-micron, absolute rated filter cartridges to prevent excursion of any very small particles and prevent any solids and ion exchange resin from traveling through the purified water delivery system.

13. The filtered deionized water then is degassed by a hydrophobic membrane that separates gas bubbles and dissolved gasses using a vacuum source as the driver for gas removal.

14. The purified water then flows out the supply port of the purification system and into the Facility deionized water delivery piping where the water can be injected into the Gamble III machine.

The water then returns to the pure water storage tank from which it is continuously pumped through the polishing equipment and back out through the purified water piping network.

Constant DI Water delivery pressure is maintained by an automatic back-pressure valve at the return point to the DI Water storage tank. This continuous circulation system configuration is designed to ensure that the deionized water continuously maintains its high quality.

15. When it is desired to flow water through the Gamble III machine, a 3-way flow selection valve is activated and DI Water flows from the DI Water system purification outlet to the machine.

16. When the machine purges used water, a variable frequency drive (VFD) evacuation/transfer pump, connected to a gravity pressurized drain port on the machine then pumps the used water from the machine either delivers the water to the large storage tank or removable collection tank/tote for inspection prior to discharging. The used water could then be processed by oil absorption and pH neutralization to be sent to the sewer for disposal.

17. The system’s smaller processing tank/tote is for the inspection and processing of a 275-300-gallon volume that is either discharged directly from the machine using a branch installed tee fitting with valve or from the bottom of the 10,000-gallon storage tank via an automatic/manual valve. The smaller storage tank/tote will be removable and will need to be outfitted with 3-inch quick disconnect CPVC unions. This tank/tote will be necessary for inspection and act as a buffer tank for evacuation of water in the event of a catastrophic failure. If too much oil gets into the DI-Water system processing equipment there will be a catastrophic consequence. The oil filter media is designed to claim at least 90% or more of the dissolved oil created during routine operation. In a catastrophic event where the transformer oil is no longer dissolved or entrained in the water it will be free to float to the top of the large storage tank, machine, or tote. If there is concern of a catastrophic event the machine would be required to sit idle to allow the oil to float to the top of the machine or storage tank where the 300gpm VFD pump would be manually turned on and valves set up to transfer the oily water and discharge it into the small tank/tote for inspection. If there is more oil than water the tote would be forklifted to the onsite oil purification system for reclamation of the oil. Once the free oil is removed from the tote the remaining water will be evaluated for reprocessing or to be sent to the sewer via the neutralization and waste management system described in this document.

18. The system shall be fully automated for unattended routine operation. The manufacturer of the system will provide advanced programmable logic controls (PLC), local touchscreen Operator Interface (OI) panels, and be controllable using Ignition software by Inductive Automation as the main facility control system from the operator control room. Since the DI-Water System will be isolated from the machine, a mirrored Operator Interface shall be provided for mounting within the machine operation Room 152 on the secondary transfer skid to enable system monitoring and control during DI-water equipment operation. System alarms, warnings, and maintenance alerts are all visually and audibly annunciated locally and at all control panels.

The Advanced Controls are fully capable of being integrated into the local network for control, performance viewing, and alarm annunciation. The system will require programming of operations outlined in this document as well, but not limited to, program operations listed in Figure-3.

19. The OI panels shall display flow rates, pressures, storage tank and machine DI-water levels, resistivity, particulate count, % dissolved gas, and filter vessels differential pressures.

20. The DI-water system also needs manual emergency stop buttons and lock-out-tag-out power disconnects located on the main control panel of the main DI-water system skid in room 152 and within 6 feet of the second pump which is in Room 152 near the machine.
