Ampac USA Sea Water Desalination Land based watermakers 20,000 GPD
Production Capacity:
20,000 GPD (Gallons per Day) / 75,700 LPD (Liters per Day) / 3.2 m³/hr.
Make of System:
Fully Automated Turnkey Sea Water Desalination Watermaker (SWRO) for Land Based Applications, Larger Boats, Ships, PSV, MPSV and AHTS type Vessels. This SW20K-LX includes Pre-Treatment Modules, Seawater Reverse Osmosis Process and On-Demand Delivery with Post-Treatment Modules to Point of Use, fully built on a Fully Welded, Double Powder Coated Aluminum Skid with Diamond Plate Base using best industrial practice and following manufacturer’s guidelines for every component as follows:
Main Components:
Programmable Logic Controller (PLC): All AMPAC USA Seawater Desalination Watermakers are equipped with a Microprocessor Controller features an Alphanumeric Backlit LCD Screen to display operating conditions, and provides adjustable time delays and set points to accommodate varying field conditions in an NEMA 4X Rated Enclosure. The controller displays the permeate Salinity (TDS/Conductivity), water temperature, and operating hours along with the operating status of the RO unit. The PLC also monitors Low and High-Pressure Switches, Tank Levels, and Pre-Treatment Equipment. It provides relay outputs for the Watermaker high-pressure pump, inlet valve, membrane flush process, and optional relays for permeate divert or remote alarm and auxiliary output, Optional Remote Monitoring and Control Available.
Noise Reduction:
All AMPAC USA Watermakers comes equipped with an Accumulator Pulsation Noise Dampener to reduce noise and vibration to acceptable Decibel Noise levels.
Monitors:
- Stainless Steel Glycerin Filled Pressure Gauges: Installed after each Stage to monitor Pressure at every step of the desalination process.
- Visual Flowmeters: Those Flowmeters are installed to monitor Productivity Permeate and Concentrate.
- Salinity Monitor: Shows actual Product Water Quality, an Essential Tool for Product Water Monitoring.
- Hour Meter: To maintain accurate logs of operation hours and keeping schedule preventative maintenance.
- Temperature Monitor: To keep accurate logs of production capacity versus temperature of feed water supply.
Safety Features:
- All AMPAC USA SWRO Watermakers are equipped with Low Pressure Sensors for failsafe operation.
- All AMPAC USA SWRO Watermakers are equipped with High Pressure Diverter Valves for Operator Saftey.
