Most advanced boats currently rely on water treatment machines that generate freshwater instantaneously. This has unlocked the constraints that made voyaging limited. Underneath, our experts provide professional answers to the web’s most asked questions about boat watermakers.

➣ What is a Boat Water Maker?

A boat water maker is a desalination device deployed in water vessels to supply freshwater by treating seawater. Technically, marine water makers convert seawater into potable water for distinct applications in water vessels. Primarily, these desalination devices accomplish this by deploying the reverse osmosis process, which typically evicts 95-99.7% of the dissolved salts. Modern water makers are realistically economical, highly productive, and quite easy to operate.

There are distinct water makers characterized by differences in size, production capacity, and design. This ensures that small boats, cargo ships, cruise ships, and virtually all forms of water vessels have specialized equipment. Boat water makers have characteristically high TDS levels, which facilitates their operation in highly saline seawater, for instance, 45,000ppm in the Red Sea.

➣ What Are the Advantages of Boat Water Makers?

Boat watermakers have revolutionized water transport. They provide high-grade freshwater to water vessels for human consumption and regular boat maintenance. This abolishes the need for water tanks, which were previously the only source of freshwater for boats. A water maker provides potable water when needed. Therefore, there is no risk of running out of potable water and sailing can carry on for as long as you want. The following are additional advantages of boat watermakers.

• They are compact hence they facilitate the efficient utilization of space. This creates more space for personnel, travelers, or even valuable luggage.
• Owing to their high rejection membranes, they are very effective in eliminating objectionable impurities.
• They are made of non-corrosive material, which makes them quite durable.
• Plug-and-play installation.
• Efficient in power consumption.

➣ How Does It Function?

Boat water makers are characteristically reverse osmosis machines custom-made for water vessels. They eliminate dissolved salts and other undesirable contaminants using the reverse osmosis process. Often, water makers for boat comprise sediment filters, which remove sand, debris, colloids, seaweed, plastics, and other suspended matter in the seawater. This makes certain the RO membranes remain unclogged and highly performing.

The pretreatment seawater is consequently pressurized to ensure the feed water pressure surpasses the conventional osmotic pressure. This reverses the natural osmosis process, enabling the rollout of the reverse osmosis process. The inlet water passes through semipermeable membranes, which only allow water molecules to pass. Some low-molecular-weight elements also pass through the membrane perforations.

The dissolved salts, proteins, minerals, viruses, and bacteria are held off by the membranes and kept in the retentate side. They are properly discarded together as a concentrate or treated. The water molecules that pass through the partially perforated membranes are harvested as permeate. Here is a visual illustration of how boat watermakers work.

➣ Which Pretreatment Technologies Are Used by Boat Water Makers?

Pretreatment is an imperative process in reverse osmosis desalination hence most marine water makers have integrated pretreatment systems. In fact, the long-term performance of desalination systems for boats hinges on the pretreatment processes employed. Beneath, we discuss the highly-regarded boat water maker pretreatment technologies.

●       Sediment filtration.

Sediment filtration relies on media filtration systems like pressure sand filters or multimedia filters to capture suspended solids and lessen turbidity. In essence, this pretreatment process eradicates high molecular weight constituents capable of blocking the membrane pores. By preventing the clogging of the membrane perforations, sediment filtration elongates the lifespan of your boat water maker.

●       Carbon filtration.

This is a media filtration process that eradicates organic chemicals, pesticides, chlorine, and VOCs using activated carbon filters. Through adsorption, these pollutants are captured by the AC filters thereby removing the awful odor and taste in your feed water.

●       Chemical dosing.

Chemical dosing involves the injection of chemical reagents that eradicate or nullify certain pollutants. Chlorination is a popular chemical dosing technology that disinfects water by killing living microorganisms. Antiscalant injection is another form of chemical dosing that eradicates dissolved ions such as calcium and magnesium. Other pretreatment technologies employable in boat water makers include;

• Ultrafiltration.
• Ion exchange.
