Service & Maintenance:
Stage 1: On-Demand Feed Supply Pump to pull the Seawater from the Seacrest on Board.
Stage 2: Stainless Steel 316L Sand Separator with an Automatic Flush Valve for Silt and Muddy Areas down to 5 Micron
Stage 3: Five-micron Sediment pre-filter that reduces sediment, sand, silt, and rust particles that may be in your water supply down ti 5 Micron.
Stage 4: A heavy duty Five Micron Lead, Chemical and Organic reducing Carbon Block Pre=Filter (LVOC). This specially formulated block is capable of reducing lead as well as harmful Volatile Organic Chemicals.These water contaminants come from a variety of sources including localized use of herbicides and pesticides, gasoline or oil spill.
Stage 5: Injection of Anti Scalant solution is included to prevent the silica scaling, CaC03 and CaS04 in the RO membranes, consisting of Antiscalant tank, metering pumps, tank mixer and tank level switch.
Stage 6: Improved FILMTEC™ seawater reverse osmosis elements offer the highest productivity while maintaining excellent salt rejection.FILMTEC SW membrane elements have the highest flow rates available to meet the water demands of both sea-based and land-based desalinators. FILMTEC SW elements operate at lower pressure to reduce cost and operating expenses.
Improved FILMTEC seawater membrane combined with automated, precision element fabrication result in the most consistent product performance available.
Stage 7: Extruded activated carbon filter consist of virgin activated carbon powder, a thermoplastic binder, and specialty adsorbents such as zeolites oxidizing filtration media. The filters are manufactured as continuous lengths of rod, tube, slab, flexible flat sheet, or as other complex shapes using a proprietary solid-state extrusion process. The resulting products are highly porous and extremely uniform, providing high-performance adsorption and particulate reduction at low flow resistance when fabricated into finished filter elements.
Extruded activated carbon filters meet exacting performance requirements and/or claims, and specific models are registered as meeting the requirements of NSF/ANSI for VOCs and THMs reduction, particulate, cyst, turbidity, lead reduction, chlorine taste and odor reduction, and other requirements relating to purity and safety of their materials of construction.
Stage 8: 0.5 Ceramic Post Filter This Post-Filter is a self-sterilizing ceramic locked with bacteriostatic silver. The candle filter has an absolute rating of 0.5 microns, filtering a wide range of contaminating particulates. Additionally, it eliminates E. coli, cholera, salmonella and more. It is NSF certified for Standards 42 & 53, Excellent performance is Reliability after the Sea Water Desalination Process.
Stage 9: Ultraviolet disinfection is a means of killing or rendering harmless microorganisms in a dedicated environment. These microorganisms can range from bacteria and viruses to algae and protozoa. Ultra Violet disinfection is used to disinfect and sterilize Permeate Product Water after the Desalination Process. A major advantage of UV treatment is that it is capable of disinfecting water faster than chlorine without cumbersome retention tanks and harmful chemicals. UV treatment systems are also extremely cost efficient!
The Ampac SeaPro™ Sea Water Desalination Water Maker is the next generation Turnkey system designed for Commercial Marine and Navy Applications with internal High Pressure Booster Pump for ease of use in compact locations. Featuring a simple interface, the SeaPro Plus™ can be monitored via the control panel or the on-deck Remote Control. All components within the frame are readily accessible for easy maintenance.
