12 Tips to Help You Get Quality Marine Water Makers


Marine water makers are a convenient and essential piece of equipment for boats and ships that spend extended periods of time at sea, as they allow the crew to have a reliable source of drinking water without having to carry large quantities of water onboard. They are also useful for boats and ships that operate in areas where there is a limited supply of fresh water, or for emergency situations when fresh water is not readily available.

We know that for many friends, the multiple seawater desalination equipment on the market is dazzling, and it seems difficult to find a reliable and high-quality marine water maker manufacturer. But with these 12 tips, finding the right manufacturer will be easier for you. If you’re new to buying a water maker or aren’t sure where to start, this article is for you!

We’ve compiled the best practices on shopping for marine water makers so that you can find holistically sound solutions quickly and cost-effectively.

-How Does the Reverse Osmosis Watermaker Work?

A seawater maker is a device used on board to produce fresh drinking water from seawater. A reverse osmosis system is generally composed of a pretreatment system, a multi-stage high-pressure pump, a reverse osmosis membrane element, a membrane shell (pressure vessel), and a support. The water generators used in the marine field are usually designed to save space and be easily installed in modular, skid-mounted, and container-type. It works by using the reverse osmosis process to filter out salt and other impurities from seawater, leaving behind pure, fresh drinking water.

Utilizes the working principle of reverse osmosis. Under the action of the high-pressure pump, the outlet water of the security filter is boosted to the working pressure of RO, and then evenly distributed to the pressure vessel. When the influent water passes through the reverse osmosis membrane with a pore size as small as nanometers (1 nanometer = 10-9 meters), it is separated by the reverse osmosis membrane. So as to achieve the purpose of removing inorganic salts, heavy metal ions, organic matter, colloids, and various harmful substances in the water to obtain pure water. The produced water can reach the standard of drinking water.

-How to Choose the Best Sailboat Watermakers?

With so many different marine water makers on the market, it can be difficult to know which one is right for you. In this section, we will provide 12 tips to help you get a high-quality marine water maker that will meet your needs and ensure that you have clean, safe drinking water for your water vessel.

1. Determine Your Water Needs

Before you start shopping for a seawater maker, it’s important to determine your water needs. This means that you need to determine your demand for produced water, that is, where the produced water will eventually be used.

Because the water quality requirements of the produced water are different, the processes that need to be treated are different, and the system configuration of the equipment is also different. For example, your produced water does not need to reach the quality of drinking water but is used for washing clothes and showering, so you can choose a relatively low-cost process. If you need pure water, then you need equipment with higher filtration accuracy. If you want to sanitize further, it would be a good idea to add a UV germicidal system at the end of the water treatment system.

Therefore, the water quality of the produced water also determines the quotation of the whole system.

2. Research Different Brands and Models

Although the lower the price, the supplier of the water generator has more advantages, but we should also know the existence of brand premium.
There are many different makes and models of seawater generators on the market, so we recommend that you do your research, and find reviews and testimonials from other boat owners, so you can get the best quality water generator for your budget

3. Consider the Type of Water Maker

Based on the membrane process, there are two main types of seawater water generators: nanofiltration and reverse osmosis.
Reverse osmosis desalination equipment has long been considered expensive. Therefore, some people will consider using nanofiltration equipment with relatively low counterfeit when the water quality requirements are not high。

Based on seawater desalination technology, EDI equipment, distillation equipment, deionization equipment, etc. are common. Different types of water generators cost differently.

4. Look for a Water Maker with a High Recovery Rate

The recovery rate of a water maker refers to the amount of water it can produce compared to the amount of seawater it consumes. A higher recovery rate means that the water maker is more efficient and can produce more water with less energy and resources.

5. Pay Attention to The System’s Capacity

The capacity of a water maker refers to the amount of water it can produce in a given period of time. It’s important to select a water maker with a capacity that meets your needs, as a system that is too small may struggle to keep up with demand, while a system that is too large may be unnecessarily expensive. Generally, seawater desalination equipment with larger capacity is more counterfeit and correspondingly requires higher installation and maintenance costs.

Start by determining your daily freshwater needs. You can use the size of the boat, the number of people on board, and the use of fresh water to roughly estimate the daily freshwater requirements per person. Then estimate the hourly water flow demand based on the working hours of the equipment. To ensure that the output demand is exactly what you want.

6. Check for Durability and Reliability

Marine water makers are subjected to harsh environments, so it’s important to select a system that is durable and reliable. Look for features such as corrosion-resistant materials and reliable pumps and membranes.

7. Consider the Maintenance Requirements

All marine water makers require some level of maintenance, so it’s important to consider the maintenance requirements of the system you are considering. Look for systems with easily accessible components and simple maintenance procedures.

8. Check the Warranty

Marine water makers are expensive investments, so it’s important to select a system with a good warranty. Look for a manufacturer that offers a comprehensive warranty that covers all components of the system.

9. Consider the Installation Process

The installation process for a marine water maker can be complex, so it’s important to consider the ease of installation when selecting a system. Look for systems that come with detailed installation instructions and consider hiring a professional to install the system if you are not confident in your own abilities.

10. Think About the Location of the System

The location of the water maker on your vessel is important, as it needs to be accessible for maintenance and repair. Consider the space and layout of your vessel when selecting a desalination system.

11. Consider the Operating Costs

The operating costs of a marine water maker can vary significantly depending on the type of system and the efficiency of the system. Look for systems with low energy consumption and low maintenance costs to save money in the long run.

12. Get Professional Advice

If you are unsure which marine water maker is right for your needs, consider consulting with a professional. They can help you evaluate your options and make an informed decision.

By following these tips, you can be confident that you are selecting a quality marine water maker that will meet your needs and provide reliable service for years to come.

· Reliable and Consistent Water Supply

One of the main benefits of marine water makers is that they provide a reliable and consistent source of fresh water, regardless of the location or availability of other water sources. This is especially useful for long voyages or extended periods of time at sea, where it may not be practical or possible to resupply with fresh water.

· Cost-Effective

In many cases, using a marine water maker can be more cost-effective than carrying large amounts of bottled water or constantly replenishing water supplies at ports. These systems can produce a significant amount of fresh water per day, reducing the need for frequent resupplies and the associated costs.

· Environmentally Friendly

Marine water makers can help reduce the environmental impact of boating by reducing the need for bottled water and the waste associated with its production and transportation. These systems also use a small amount of energy to operate, making them a more environmentally friendly option compared to other water treatment methods.
