300 GPM Zero Discharge System brine evaporator/crystallizer system (ZLD) System includes a falling film evaporation system, with mechanical vapor recompression, and a forced circulation crystallizer. previously used by a major utility company. This process has been maintained to an excellent standard. The overall system is designed to concentrate 300 GPM flow rate Reverse Osmosis reject stream to essentially dry, land fillable solids. Distillate produced in the evaporator / crystallizer is of high quality ( less than 10 mg/l TDS excluding volatiles) and suitable to recycle. There are two 150 GPM, MVR falling film Brine Evaporators followed by a 50 GPM feed flow rate, steam driven, forced circulation type Brine evaporative crystallizer. A centrifuge is integrated with the crystallizer to produce solids suitable for a landfill. All major and minor components are included including some but not all field instrumentation. The evaporator uses "seeding" crystals in the slurry in order to prevent scale up on the tubes. Major items are as follows: Two (2) 150 GPM falling film evaporators with titanium tubes, and flood box/sump constructed of AL6XN and 316 SS. Each evaporator has a MVR system with a mechanical compressor provided by Dresser-Rand, and a recirculation pump by ITT rated for 5000 gpm. ( IPP stock numbers 228146 & 228148) ; One 50 GPM crystallizer, previously had a rubber lined vessel, but was removed due to bad rubber. (vessel can be re fabricated from either SS or CS). Also with a 3,500 sq.ft. shell and tube heat exchanger, and a recirculation pump rated for 19,000 GPM. The heater has wetted parts of AL6XN, and the pump alloy is CD4MCu. ( IPP stock numbers 228100 through 228110) Dry product is discharged through a Bird centrifuge rated for 18,000 lbs./hr. (IPP stock number 228101)
