SWC Series Capacity

Our SWC Series is available with capacities ranging from 380 GPD to 10,000 GPD and a maximum feed water TDS of 42,000 ppm. We offer standard SWC Series units as well as customizable to fit you water application needs. Whether it's for your luxury yacht, cruise line, or for a five star resort on the beach, Pure Aqua has the right desalination system for you project.

Customizable For Your Needs

When your needs demand continuous-duty, commercial-grade watermaking, the solution is very clear. The Pure Aqua reverse osmosis water maker is efficient and extremely reliable. These marine desalination systems deliver great volumes of potable fresh water with capacities ranging between 380 to 10,000 GPD. Ideal for commercial vessels, island homes, oil platforms, hotels, or large yachts. These water makers convert salt water to fresh water and provide service wherever clean, pure, fresh water is needed. Employing our advanced microprocessor control panel, our saltwater to freshwater converter enables state-of-the-art, total control and user-friendly system customization.

Choosing the right watermaker for boats

Before advancements in desalination technology, having a water maker aboard a cruising boat was considered as a desirable luxury item. Today, most sailboats carry a reverse osmosis system, which improves the overall experience of setting sail, specifically in areas where freshwater is unavailable. While water makers might not be required for boats near dockside, boaters cruising throughout offshore locations depend on the sailboat water maker for daily hydration. Long-term voyages on sea is made much more convenient with a quality watermaker onboard and possible for boaters who dream about living living off the grid. Other basic necessities such as showering and cooking are made possible by sailing with a cruise ro watermaker.

How does a marine water maker work?

Obtaining fresh water is taken for granted in many geographical locations such as in urban areas within developed countries. However, such locations do not afford people with the ease of attaining freshwater supplies in sufficient quantities to drink and use in other applications. For instance, hot/arid areas and remote islands throughout the world provide very few water sources to the people who inhabit these specific regions. One application which depends solely on the usage of a marine water maker for the production of freshwater is offshore installations. As ships cruise further offshore and away from any means of freshwater production from natural sources such as rivers, lakes, springs, and wells, the only real chance of acquiring clean water is from the ocean itself.

While the ocean provides an abundant amount of water to marine water boats, it contains extremely high concentrations of salt, which makes it unusable in virtually any application, including consumption. To remedy this issue, boat owners that look to spend a great deal of time off-shore, make sure to carry a marine water maker on board in order to convert seawater into purified, freshwater. The water produced from marine water makers are of the highest quality and can be used for drinking, washing, showering, etc.

A boat water maker works by utilizing the process of reverse osmosis which specifically targets impurities in water such as salt and minerals and excluding them from the finished product water. This is done through the employment of pressure pumps, which pushes the untreated water through semi-permeable membrane elements that use small pores to filter out these unwanted contaminants from passing along with the water. The contaminants are subsequently flushed away, and the newly purified water is kept and ready to be used. High-pressure pumps are required to use for treatment operations regarding seawater since it possesses greater degrees of salt and other pollutants. A quality sailboat water maker is proven to eliminate up to 99 percent of dissolved salt and minerals from seawater.

Maintenance for watermaker

Watermakers have developed a reputation for becoming hard to sustain over a period of time, but over the years the machinery has changed and, generally, daily maintenance has been made much simpler. However, keeping your water maker polished for quality performance is critical. A boat water maker that is operated in polluted harbors will inevitably lead to clogged parts and require frequent adjustments to the filter media. Boaters can scrape through by having more filters on board but it is ill-advised. The climate is much safer inside the open sea and isolated anchorages. Remember as well the shallowness of the water where you are anchored, since the possibility of tidal movements will often occur and stir up small particles and sediments. This may also lead to additional adjustments in the filter and may even affect other parts. An automatic freshwater flush is a good choice that will clean the membrane portion of the marine water maker after use. It means keeping the housing of the membrane vessel safe from any organic matter which might foul the membrane and lower the capacity to generate fresh water.

    The SWRO is good priced

    Posted by Victor T. on Jan 17th 2018

    The SWRO is good priced but components they used are not “cheap”. The system provides my business with 2,000 Gallons of water daily with consistent water quality. Check them out if you are in the market for any RO system.

    It is more energy efficient

    Posted by Ralph F. on Aug 10th 2017

    We replaced an old RO due to old age and we got Pure Aqua's 3,000 GPD system. It is more energy efficient and footprint is smaller than our old system which has lower flow rate capability. Nice and modern-looking machine.

    Great looking and designed SWRO system

    Posted by Jack A. on May 7th 2017

    Great looking and designed SWRO system. I have the SW-3.0K-304 installed in our family beach front cottage. Works well with our power source and provides water with consistent water taste and quality. Great system.

    Very good system.

    Posted by Walter D. on Feb 2nd 2017

    We are currently using Pure Aqua's SW-4.7K-504 and converting beach well water into drinking quality water. This system came with all the needed pre-treatment equipment. So far it's been running well and no issue. Very good system.

    We are very satisfied with our investment.

    Posted by Arthur M. on Dec 4th 2016

    You get what you pay for is what I can say with this compact SWRO system. There are lots of cheap SWRO here in Asia but the overall quality is cheap and un-reliable as well. We have ordered this SWRO from Pure Aqua (SW-6.0K) and shipped to the Philippines and now being used in a small coastal town for commercial water filling station. The quality of the filtered water is great and we already have recovered our investment while the system is still running consistently producing same quality of good tasting water for the buying customers. We are very satisfied with our investment.
