The Ultimate FAQ Guide for Boat Water Purification Systems

Purified water is an essential commodity for boats during voyages. Owing to the invention of water purification systems capable of generating purified water based on demand, water vessels are steadily ditching freshwater tanks. The purification systems permit boats to draw their purified water from the surrounding seawater or ocean water, which is more convenient and economical than carrying freshwater tanks. Underneath, we are going to comprehensively look at the desalination units for boat, their primary features, and elaborate working principles.

➣What is a Boat Water Purification System?

A boat water purification system is a water treatment unit that extracts undesirable constituents from seawater or lake water to supply boats with purified water. Boat water purification systems are commonly referred to as boat water makers. Most boats operate in seas and oceans characterized by relatively saline water. Boat water purifiers designed for such boats primarily utilize the reverse osmosis process to desalinate the salty water.

However, other distinct technologies such as water deionization and thermal desalination can also be employed. For high-level purification, the water makers incorporate several water purification technologies. Additionally, most comprehensive boat water purification units comprise a water pretreatment system used to expel aggressive contaminants. The systems are also manufactured using rust-resistant material due to the volatile nature of seawater.

NEWater’s expertise in manufacturing desalination units for boats stretches to over two decades. Our systems are expertly manufactured and customized in relation to the characterization of your feed water. They are ingrained with energy-recovering technologies, which significantly shrink their operating costs.

➣Which Purification Methods Are Employed in Boat Water Purification Systems?

Reverse osmosis is the dominant water purification technique employed in boat water purifiers. However, numerous alternatives can be employed depending on the composition and concentration of the feed water. Below is a brief discussion of the prominent processes employed in boat water purification units.

● Thermal desalination.

Thermal desalination is a purification mechanism that involves evaporation and condensation. The seawater is essentially boiled in a boiling chamber until it converts into vapor or steam. The steam penetrates through ventilation on the boiling chamber and enters the condenser. In the condenser, a first-rate fan chills the steam, consequently turning it into liquid water. All constituents with a higher boiling point compared to water remain in the boiling chamber. They include dissolved solids, minerals, microorganisms, and floating solids. Thermal desalination is further divided into;

● Multi-effect distillation.

Multi-effect distillation is a thermal process that separates impurities from water through evaporation and condensation. The process is undertaken in a series of vessels, which are commonly referred to as effects. The temperature in the successive effects decreases gradually since the water’s boiling point lessens relative to the pressure drop. The following animation video illustrates how MED desalination works.

● Multi-stage flash (MSF) distillation.

Multi-stage flash distillation is a purification process that evaporates and condenses seawater in a number of stages. In the first evaporator, the feed water is heated at high pressure and temperature but in the subsequent vessels, the pressure drops steadily. Condensation of the vaporized water is accomplished using incoming feed water.

● Reverse osmosis.

Reverse osmosis is one of the most advanced boat water purification processes. It is a membrane-based water purification process that is chiefly driven by pressure. The feed water is initially pretreated using sediment filters to expel suspended solids, which can clog the partially porous RO membranes. After pretreatment, pressure is exerted on the feed water to overwhelm the conventional osmotic pressure.

The semipermeable membranes seize components with high molecular weights including dissolved salts and microbial pathogens while water is allowed through. The trapped constituents are left on the retentate side while the purified water moves to the permeate side. The brine (wastewater) can be fed into the reverse osmosis system for treatment while the permeate (filtered water) is collected and ready for use.

● Water deionization.

Water deionization is a purification mechanism that interchanges ionic contaminants with non-objectionable ions. Seawater contains minerals, metals, and dissolved salts, which are characteristically ionic compounds. Positively charged elements such as sodium (Na+) are swapped for hydrogen (H+) by the cation deionization resin while negatively charged elements such as chloride (Cl-) are substituted by hydroxide (OH-) ions.

➣Why Do I Need a Boat Water Purification System?

Water purification systems have over time become quite essential equipment in boats. They generate purified water for boat maintenance, the crew members as well as passengers on a per-need basis. This means that you no longer have to load up your boat with large tanks to have a water source. In addition, you can carry on with your expedition without having to make unnecessary stops to refill your dwindling water tanks.

A boat watermaker essentially paves the way for infinite voyages. The machine will provide you with high-quality purified water, which can be safely consumed by people on deck. The water can also be used to undertake regular boat maintenance such as cleaning and engine cooling. The following are some of the many rewards you can expect once you procure a boat water purifier for your water vessel.

• Your boat will weigh less and can achieve higher speeds since you are not carrying large tanks of water.
• They are relatively inexpensive to purchase and incur low maintenance costs meaning you are guaranteed quick returns on investment.
• They are energy-efficient thanks to energy recovery.
• They have incredible impurity rejection rates, which guarantee first-rate purified water.

➣What Types of Boat Water Purification Systems Do You Provide?

NEWater’s reputation as a credible manufacturer of water treatment systems dates back over 20 years ago. Over that time, we have massively grown our catalog of products and our market reach. We precisely manufactured thousands of boat water purification systems and supplied them to over 200 countries. Underneath, we briefly discuss some of our most coveted boat watermakers.

● Reverse osmosis boat watermakers.

 Reverse osmosis (RO) watermakers are boat water purification units that primarily rely on reverse osmosis to turn seawater or lake water into purified water. Our RO boat water purifiers are typically manufactured in TDS ranges of 1,000ppm to 45,000ppm. This allows them to desalinate brackish water as well as extremely saline seawater. Moreover, they average an impurity removal score of 95%-99.7% meaning they generate first-rate potable water. We primarily manufacture them in skid-mounted, modular, and containerized designs.

● Thermal distillation systems.

Thermal distillation systems are purification systems dependent on the processes of evaporation and condensation. They consist of a heating medium, evaporator, condenser, and control valves. These systems are ideal for seawater and brackish water desalination and are proficient in extracting dissolved salts, minerals, floating solids, and harmful microorganisms. We equip our thermal distillation systems with energy recovery technologies to mitigate energy wastage. Our main thermal distillation systems are;

• Multi-effect distillation (MED) systems.
• Mechanical vapor compressors (MVR).
• Multi-stage flash distillation units.

● Deionization machines.

Deionization machines are water purification units that technically replace ionized elements in water with non-objectionable ions. They consist of a cation di resin and an anion di resin. The cation di resin is ordinarily charged with hydrogen (H+) ions while the anion di resin is often charged with hydroxide (OH-) ions. The H+ ions substitute the positive pollutant ions while the OH- ions replace the negative pollutant ions. Deionization machines remove dissolved ions, minerals, dissolved salts, and traces of metal.

➣How Much Does Boat Water Purification Cost?

At present, purifying seawater or lake water for boat usage has more financial rewards compared to carrying water tanks. Water purification technologies have become cost-efficient over time and this has fundamentally decreased the cost of turning seawater into freshwater. The cost of running a boat water purification system depends on numerous factors, for example, the concentration and composition of the feed water. Feedwater with relatively high concentrations of contaminants tends to be more expensive to purify.

Other factors that determine the cost of purification include the purification process employed, the size of the equipment, and the purification level. The production cost entails components such as human labor, power usage, repairs, and replacements. Generating purified water from seawater using a reverse osmosis boat water maker ranges from $0.79 to $2.38/m3.

Using thermal desalination systems, specifically multi-stage flash distillation systems costs approximately $ 1.00/m3. The drop in production costs over the years is primarily attributed to the development of more cost-efficient boat watermakers. In addition to incurring lesser operational costs, our boat water purification systems are also priced affordably.

➣Which Pre-treatment Systems Are Ideal for Boat Water Purification Systems?

Owing to the composition of seawater and lake water, most boat water purification systems demand an integrated pretreatment unit. Seawater often consists of floating solids, sand, particulates, and other suspended matter, which can potentially block the semi-porous membranes leading to poor performances and untimely damage. Underneath, we are going to walk through some of the water pretreatment systems that can help your boat water maker operate at an optimum level sustainably.

● Multimedia filters.

Multimedia filters are unquestionably one of the best filtration systems when it comes to the removal of total suspended solids (TSS). They are technically made of different filtration material, which is arranged with respect to size. Ordinarily, the materials used are anthracite, sand, and garnet.

● Pressure sand filters.

Pressure sand filters are typically made of one filtration material. However, the filtration media is strategically arranged in multiple layers based on size, gravity, and porosity. Although they are not as effective as multimedia filters, they shrink turbidity and extract huge volumes of suspended solids, colloids, and seaweed.

● Ultrafiltration filters.

Ultrafiltration filters seize suspended solids, colloids, and high-molecular-weight elements using partially permeable membranes. Typical UF membrane filters have an average porosity size of 0.005–0.1 μm. Their filtration rate is unparalleled and they also extract small traces of dissolved salts and microbes.

● Chemical dosing systems.

Chemical dosing systems are mainly used to inject chemical reagents like antiscalants into the feed water. Antiscalants help eradicate pollutants such as magnesium and calcium, which can result in scaling. Chlorination is also undertaken using chemical dosing systems and it seeks to destroy microbial pathogens.

➣How Much Power Do Water Purification Systems

for Boat Necessitate?

A few decades back, desalinating seawater was considered an energy-intensive process and this contributed to a low adoption rate. However, efforts to make reverse osmosis membranes more efficient and minimize the wastage of power paid off. Contemporary boat water purification systems use the most efficient membranes and energy recovery devices thereby resulting in low energy consumption rates.

A typical RO boat water maker currently consumes between 3 kWh/m3 and 5.5 kWh/m3 of energy to purify seawater. Using mechanical vapor compression, the energy consumption ranges from 7 kWh/m3 to 12 kWh/m3. In multi-effect distillation and multi-stage flash distillation, the average power consumption range is 6 kWh/m3 to 11 kWh/m3 and 13 kWh/m3 to 25 kWh/m3 respectively.

The difference in power consumption depends on the primary water purification process, the feed water concentration, and the scale of operation. Purifying water with a comparatively higher salinity level consumes more energy. For the most power-efficient boat water purification system, get in touch with NEWater.

➣Do You Provide Solar-Powered Boat Water Purification Units?

Solar energy is not only cheaper but is also safer for the ecosystem. The use of solar energy shrinks the number of greenhouse gasses emitted hence environmentalists is actively advocating for solar power. At NEWater we manufacture varying solar-powered water purification systems including solar boat watermakers. Solar-powered boat water purification systems mainly exploit solar energy indirectly.

They comprise a separate solar collection and transmission system, which provides power to the water purification equipment. A typical solar power system consists of solar collectors, photovoltaics, and storage batteries. The heat from direct sunlight is absorbed by the solar collectors and transmitted to photovoltaics. The photovoltaics convert the energy into electrical power, which is then transferred to the boat water maker.

High-voltage batteries can be integrated to preserve excess energy, which can be used at night or on rainy days. Solar boat water makers are ideal for off-grid applications and they massively decrease the cost of operation. Some of our solar-powered boat water purifiers are：

• Solar-powered reverse osmosis water makers.
• Solar-powered ultrafiltration systems.
• Solar-powered distillation systems.
