How to Choose a Portable Desalination Equipment

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 the 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?

3.0 Introduction to NEWater Portable Desalination Equipment.

NEWater portable desalination equipment is our latest 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 a good water quality, which can ensure a stable water supply for residents.

NNEWater 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 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.

NEWater portable desalination equipment 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 during 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 equipment and improved its mobility by the comprehensive design. Considering the different environments, the system designs to use the AC100-240V (50/ 60Hz) AC power supply/ DC24V DC power supply to ensure the better use of the equipment.

Portable Desalination Equipment components

4.0 Process Description of NEWater Portable Desalination Equipment

The whole process of portable desalination equipment adopts 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 which 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 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)

5.0 Application Scenarios of NEWater Portable Desalination Equipment

(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, it may cause serious problems with the ship’s draught if used large desalination equipment during navigation.

Based on this, the portable desalination equipment on board is undoubtedly the best solution. Our portable desalination equipment uses a luggage-style design, it is not only lightweight and portable but also 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. And 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 rely 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.
