How to Choose a Portable Desalination System

1.0 Significance of Desalination

Societies are developing faster and faster, and the contradiction between the increasing human demand for water and the imbalance and inadequacy of depleted freshwater resources is becoming more and more apparent. The phenomenon of water shortage has seriously affected the human living environment. Although there are many beneficial elements in seawater, most of them are above the concentration, with many harmful substances. It will bring a variety of harm to the human body after drinking it.

Therefore, in order for seawater to be well used by humans, it needs to be converted into usable freshwater. It is necessary to use external forces, such as desalination equipment, which desalinates brackish water through a series of processes, providing a strong guarantee for the development of human society.

Although existing reverse osmosis technology is becoming more and more sophisticated in desalination, the equipment currently available is generally large, which has many drawbacks such as high energy consumption, high costs, the need for large supporting equipment, and inconvenience of movement. Choosing a smaller and portable reverse osmosis desalination equipment can just offset these shortcomings, so how to choose good portable desalination equipment?

2.0 How To Choose A Good Portable Desalination System

A good portable desalination device can provide you with fresh water for a long time to replenish water and maintain hygiene, no matter outdoors, on camping or fishing boats, on yachts, or even in remote areas. So how do you choose the best portable desalination system? Here are some of our suggestions:

1) Requirements for equipment production capacity
The flow unit of seawater desalination equipment is generally GPD, LPD, GPH, and LPH. Before purchasing a portable desalination system, you need to make an estimate of your daily fresh water needs, taking into account cooking, drinking, bathing, cleaning, number of users, etc.
Seawater desalination equipment with different production capacities usually has different designs and costs, which means that your cost input is also different. In the case of similar water treatment technologies, the greater the demand for flow, the higher the price.

2) Water quality requirements for produced water
The water quality of the produced water is different, and the process requirements for water treatment are generally different. When the water quality requirements for the produced water are not high enough, you can choose nanofiltration technology at a lower price. In the case that you want to obtain drinking water, the seawater desalination RO system is your best choice. If you still want to carry out further purification after membrane filtration, it is best to confirm with your supplier that the equipment has a UV disinfection function.

3) Energy supply method
Common energy supply methods for seawater desalination machines on the market include manual, diesel, power supply, battery, solar energy, and so on.

Especially with the rise of solar technology in the field of seawater desalination, more and more solar desalination equipment has been applied to seawater desalination in different fields.

4) Product Quality
Choosing a quality-certified portable desalination system supplier is something you should consider.
The technical level of production equipment, technical team, and quality certification certificates all mean quality assurance. In addition, you also need to consider the material of the equipment. Seawater is corrosive, portable desalination equipment with carbon fiber, 304/316 stainless steel has the characteristics of corrosion resistance, wear resistance, longer life, and less maintenance. This means less investment costs for you.

5) After-sales service
You won’t want to be completely clueless about equipment installation, commissioning, and maintenance after purchasing seawater desalination equipment at a considerable cost, do you?

Therefore, before buying, you need to confirm that the manufacturer can provide you with complete installation, commissioning, and related training, and ensure that the equipment can be used normally and subsequent maintenance is guaranteed. Such as warranty service and warranty period service.

Portable Desalination Equipment

4.0 Introduction to NEWater Portable Desalination Unit.

NEWater portable desalination kit is our latest solar desalination product based on the principle of reverse osmosis, using seawater desalination to produce fresh water. It realizes the incremental technology of water resources development and increases the total amount of freshwater used. Moreover, it is not affected by weather and climate and has good water quality, which can ensure a stable water supply for residents.

Portable Desalination Equipment

NEWater reverse osmosis is the most precise membrane liquid separation technique; it refers to applying pressure on the solution to separate the solvent (water generally) through the semipermeable membrane to achieve the purpose of separation, extraction, purification, and concentration. Salt is the main component of seawater.

The reverse osmosis technology will separate the solvent (freshwater) from the solute (salt) in the seawater, so that the solvent permeates outside the semi-permeable membrane, while the salt is blocked by the membrane in the seawater, thus achieving desalination of seawater.

Portable Desalination Equipment components

NEWater portable desalination system mainly adopts the concept of reverse osmosis membrane permeation, which removes impurities and salt from the seawater to obtain fresh water. The primary role is to provide reliable, safe water outside or in an emergency where fresh water can’t be quoted directly.

Our company has dramatically reduced the size and weight of the portable desalination kit and improved its mobility through the comprehensive design. Considering the different environments, the system is designed to use the AC100-240V (50/ 60Hz) AC power supply/ DC24V DC power supply to ensure the better use of the equipment.

5.0 Process Description of NEWater Portable Desalination System

The whole process of the portable desalination unit adopts a suction head + self-primer pump +pp filter + high-pressure pump +RO membrane.

(1) The water purification self-priming bottom head is a type of bottom valve that is the first filtration barrier of the system. The NEWater self-priming head is made of food-grade material, it has an ergonomic design and better tactility. Wheat rice flour is an ideal water purifier and modifier with high adsorption and removal capacity for heavy metals such as lead, cadmium, mercury, arsenic, and hexavalent chromium. Due to the ion exchange effect, wheat rice flour particles can adsorb harmful components and various bacterial groups in the water, transforming the water into active mineral water while dissolving multiple minerals and trace elements that are beneficial to the human body.

(2) The self-priming pump uses a 24 V DC power supply with a rated current of 2A and a self-priming pump height of 1.5 m (vertical height). The self-priming pump has a self-priming function and does not need to provide inlet pressure, which can better meet emergency and outdoor requirements.

(3) The PP cotton box is common in water treatment. Made from non-toxic and odorless polypropylene, it is heated and melted, sprayed, drawn, and received into shape. Polypropylene cotton cartridge has a uniform pore size, sparse outside, dense deep filtration structure, high filtration efficiency, acid and alkali resistance, and excellent performance of organic solutions. Can effectively remove suspensions, particles, rust, and other impurities in water. NEWater uses a food-grade PP shell and melt-blown PP cotton filler, which can effectively reduce the turbidity of raw water to ensure the effects of purified water.

(4) 80 Stainless steel filters with mesh accuracy can prevent damage to the pump or desalination membrane from large amounts of impurities (such as debris)

6.0 Applications of NEWater Portable Desalination System

(1) For navigation. Freshwater is an indispensable and valuable resource when ship sailing. It will seriously threaten the life safety of ships and crew once water is short, in order to solve this problem, treating water with desalination equipment is a useful way. Although desalination equipment can now solve this problem, most desalination equipment on the market is relatively large and bulky, Plus the ship itself has a weight, and it may cause serious problems with the ship’s draught if large desalination equipment during navigation.

Based on this, a portable desalination unit on board is undoubtedly the best solution. Our portable desalination kit uses a luggage-style design, it is not only lightweight and portable but also has no additional burden on the boat. A win-win solution to obtain fresh water and space if you choose it.

(2)For marine operations: It is inevitable to conduct marine operations when carrying out marine-related work. Fishers sometimes go to sea for weeks or even months to catch aquatic products, but the supply of freshwater resources is very inconvenient at sea. There is no extra space for drinking water because fishing boats need to load seafood and some fishing utensils.

Moreover, most of the large desalination equipment relies on conventional power and stable energy, which is not helpful to marine operations. This is why it is important to choose small, portable desalination equipment with low energy consumption and flexible applications such as the NEWater portable reverse osmosis desalination equipment, Its small size saves floor space on board and does not require a supervised operation. Seawater can be directed to obtain drinking water anytime and anywhere to solve the draft problem of fishers.
