Ampac USA Seawater Desalination Watermaker Land Based 6,000 GPDD/ 22,710 LPD | SW6000-LX


6,000 GPD (Gallons per Day) / 22,710 LPD (Liters per Day)


Fully automated Turnkey Sea Water Desalination Watermaker (SWRO) for Land Based Applications, Larger Boats, Ships, PSV, MPSV and AHTS type Vessels.  This SWRO includ 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:


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 a 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.

Ion Exchange Water Softener:  Most Land Based Sea Water Desalination Projects feed the watermakers from Beach wells were Sea Water is mixed with well water,  Ion exchange will greatly reduce iron, manganese, Calcium and Magnesium if present in water supplies.  The ions being switched for sodium or potassium (regenerate) ions, which don’t cause the problems the other minerals, are known to create.   Inside the softener, an ion exchange material – such as a bed of small, plastic resin beads or zeolite – is saturated with sodium or potassium chloride. The material draws in calcium and magnesium, which displace the sodium or potassium into the water. When the material is completely covered through exchange, a solution washes away the removed minerals and replaces the regenerate ions before the tank is rinsed with fresh water. This process is known as regeneration.
Multimedia Carbon Pre-Filter:  Multimedia Pre-Filter will remove any excess Chlorine injected earlier, adjust pH and eliminate any excess bacteria.  Since Multimedia filter has to backwash with raw water, therefore, rinse step has been provided in backwash sequence. The filters will automatically back wash, based on timer control.
Spin Down Pre-Filter:  A Manual Flush Clear See Through Sea Water Strainer with a cleanable Mesh Screen filter for ultimate corrosion resistance and large particulate removal.   Sediment Pre-Filter:  Sediment Pre-Filter provides higher flow rates while removing dirt, sand and sediment from your water at high capacity.
On-Demand Feed Supply Pump:  This Pump is designed to supply the Watermaker with Sea Water stored previously in a  Settling Tank with the Required Flow and Pressure, This pump is a Multistage 316L Stainless Steel Jet High Pressure Pump with safeguards.  This Pump is well known for its reliability and durability.  It is are also equipped with a shaft seal and bearing system that can withstand extreme heat and friction for longer periods of time which makes it more forgiving if the pump does run dry.
High Pressure Plunger Pump:   These Triplex Plunger Pumps are designed for the Sea Water Desalination industry, resulting in pumps that deliver higher pressure and increased reliability, in fact it will Boost the Sea Water Pressure up to 1200 PSI to ensure the best Desalination Process.  A Motor Soft Start is Standard on all larger Watermakers from 4500 GPD and up that reduces start up power by 60%.
Auto Fresh Water Flush:   This Process will flush the watermaker from the inside with fresh water after each use, ensuring no salt water corrode the system extending its service life, allowing you to optimize Watermaker Performance.  This System will flush the watermaker every 24 hours if the system is not in use to prevent any bacteria growth inside the watermaker.
Sea Water Membrane Elements:  AMPAC USA Integrates the Top Quality Membrane Elements designed to convert Seawater to Drinking Water at the highest Rejection and Productivity Technology has to offer.
pH Neutralizer Alkaline Post-Filter:   After the Desalination Process, the pH of the permeate (potable) water is expected to be in the range of 5.0 this is rather, acidic. This Post-Filter will adjust the pH level to Neutral 7.0 by Re-Mineralization right at the point of delivery.
Half Micron Ceramic Post Filter:  In Many Locations of the world, Water may have contaminants which may affect the Watermaker, Ceramic Post Filters are designed to remove Particles from the water but leaves oxygen and mineral contents unchanged, which gives water it’s spring-like freshness and taste. Pathogens of the most varied diseases which are reliably filtered from the water include; cholera, ecoli, typhus, dysentery, cryptosporidium, amoebic  colibacillose or bilharzia, anthrax spores among others.  Ceramic filtration technology is often called “dead-end filtration” and “depth filtration”.
Ultra Violet Sterilization Light:  As a Final Stage, Ultra Violet Disinfection is introduced as Microorganisms in water can cause a multitude of health problems.  Ultraviolet System is the natural way to disinfect water.  UV light penetrate and destroy the harmful organism, disinfecting the water.


All Ampac USA Watermakers comes equipped with a Accumulator Pulsation Noise Dampener to reduce noise and vibration to acceptable Decibel Noise levels.
