Whether it’s for your luxury yacht, cruise line, or for a five star resort on the beach, ZamZam 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 ZamZam 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.

In choosing the correct water maker model, the following information must be provided:
- Flow rate (GPD, m3/day, etc.)
- Feed water TDS or sea source (ex: Pacific, Mediterranean, etc.)
- Seawater Source (open intake or beach well)
- Iron, manganese, and hydrogen sulfide must be removed before the water enters the reverse osmosis unit
- TSS must be removed before commercial SWC system
- Turbidity should be removed
- SDI must be less than 3
- Water should be free from oil and grease
- Chlorine must be removed
- Available voltage, phase, and frequency
- Dimensions of proposed area where commercial SWC System will be installed
Reverse osmosis system for boats cost depends on the pre and post-treatment equipment selected, such as:
