ATTACHMENTA ST. LUCIE PLANT DEMINERALIZEDWATER TRREATMENT SYSTEM SYSTEM DESCRIPTION PURPOSE The proposed water treatment system, which will provide demineralized water for normal plant operation, is intended to replace the original water treatment system.

LOCATION The proposed water treatment system will be located south of the existing water treatment plant. The system will be placed on a concrete slab with approximate floor dimensions of 50 by 100 feet. The existing stormwater drainage flow patterns in the area will remain essentially unchanged.

GENERAL SYSTEM DESCRIPTION The basic components of the proposed water treatment system are reverse osmosis followed by mixed bed demineralizers. A flow diagram of the proposed system is provided in Figure 1. The proposed system will be fed from the plant's City Water Storage Tanks, which are supplied by Ft. Pierce Utilities. The product water from the new treatment system will be routed to the Treated Water Storage Tank (TWST). A new pipe will route the wastewater from the reverse osmosis system (RO) and water softener regeneration to an existing storm drain, which discharges to the existing percolation/evaporation pond system. When the new system is fully operational and proven reliable, the Totally Enclosed Treatment Facility (TETF) and Neutralization Basin (OSN 002) will no longer be used for regeneration wastewater treatment.

SYSTEM DESIGN/OPERATION The existing 6-inch influent and effluent pipes will be tied into the proposed water treatment

.system provided by Ecolochem, Inc., bypassing the existing treatment system. The design flow rate to the system is up to 750 gallons per minute (GPM). After passing through a water softener, the water is sent to the RO and mixed bed units for final polishing. From

..the mixed.bed demineralizers, the. treated water will be routed to the existing 6-inch stainless steel pipe, which supplies the TWST.

Water Softener The water softener will require occasional regeneration with a brine solution (approximately 10% NaCI) to remove the hardness (typically calcium and magnesium) adsorbed by the resin. The softener regeneration wastewater will be discharged to the existing evaporation/percolation ponds via the plant storm drain system.

Reverse Osmosis RO and Mixed Bed Demineralizers A Carbon Filter precedes each RO unit. Reverse osmosis is a cross-filtration process which uses. pump head pressure to overcome the osmotic pressure of the feed water and "forces" a portion of the feed water (in this case 75% of the feed water- up to 400 GPM) through the membrane resulting in basically pure water (permeate). The solids, which remain behind the membrane, are concentrated in the remaining feed water (in this case, 25% of the feed water or up to 132 GPM) and are ultimately disposed in the reject water.

The permeate from the RO (up to 400 GPM) will be sent to the mixed bed demineralizers for final "polishing". prior to being routed to the TWST. The reject water from the RO (up to 132 GPM) will be routed to the existing storm drains,'which discharge to the plant evaporation/percolation pond system. Since the mixed bed demineralizers will be regenerated offsite,.there will be no wastewater discharge from. them. During the

. infrequent occasions that the product water does not meet specification for use as makeup to the plant, the water. treatment system will be automatically. shut- down:. When it is restarted, product water may be discharged to the evaporation/percolation,ponds;at a rate of up.to 400 GPM. In.this case,.the quality of the water. discharged will be excellent, since it is basically demineralized.

Chemical Addition In order to enhance the performance of the water treatment equipment, small quantities

-" of chemicals may be added'at a few points in the'process (see Figure 1). The proposed chemicals and treatment purpose are as follows:

Sodium chloride Added to the Softener to regenerate the resin.

Sodium bisulfite . Added to,RO feed,to remove any chlorine residual.

Sodium hydroxide Added to the RO feed to increase silica and alkalinity rejection.

Citric acid and Added. infrequently to clean the RO membranes. Citric acid would be Detergent neutralized prior to discharge.

Some miscellaneous reagent chemical may also. be used to;operate'.in-line process instrumentation..AII process treatment chemicals will be properly. stored. All hazardous chemicals will be provided with secondary containment with a capacity of at least 110% of the volume of the largest container within the containment.

Wastewater Qualit Com arison: Existin Versus Pro osed Figure 2 provides a comparison of the projected average discharge quality for selected parameters for the proposed system versus actual (typical) data for the existing system.

Also provided in the attachment are the estimated volumes of wastewater generated by the new system versus the existing system, based on the expected annual production of demineralized water.. Note that with the elimination of on-site demineralizer regenerations, the corrosive wastes which were routed to and treated in the existing TETF, as well as discharges to surface water via OSN 002, will eventually be eliminated.
