Clean drinking water is vital to human health, but as water pollution becomes an increasingly serious problem, water treatment has become a top concern. Common pollutants such as heavy metals, bacteria, viruses and chemicals can cause serious health hazards. To address this challenge, reverse osmosis (RO) technology emerged as an efficient and reliable water purification solution.
Working principle of reverse osmosis
Reverse osmosis water treatment technology is a relatively mature water treatment technology. Its main principle is to use semi-permeable membranes to separate ions and impurities in water, thereby removing pollutants in the water. Next, let’s take a closer look at how reverse osmosis water treatment works.
The principle of semipermeable membrane
The semipermeable membrane is the most important part of the reverse osmosis water treatment process. A semipermeable membrane is a membrane with a specific pore size, usually between 0.1-10 microns. The pore size of a semipermeable membrane can be smaller than water molecules but larger than molecules of common ions and impurities. Generally, semipermeable membranes are divided into two types: one is a nanofiltration membrane, with a pore size between 1 and 10 nanometers; the other is a reverse osmosis membrane, with a pore size below 1 nanometer.
The principle of reverse osmosis water treatment
Reverse osmosis water treatment is a water treatment technology that uses pressure to separate water from high-concentration solutions through a reverse osmosis membrane. The principle of reverse osmosis water treatment is: that when water molecules are under a certain pressure, they can pass through the pores of the semipermeable membrane, but ions and macromolecules in the water cannot pass. Therefore, reverse osmosis water treatment uses semi-permeable membranes to filter and separate impurities in the water. Semipermeable membranes allow only water molecules to pass through, while other ions and impurities are intercepted on the other side of the membrane. Generally, reverse osmosis water treatment systems are composed of pretreatment systems, reverse osmosis membrane components, pressure pumps, pipelines, and control systems.
Advantages of reverse osmosis water filtration system
Efficiently remove a variety of pollutants: RO reverse osmosis equipment can effectively remove various impurities and harmful substances in water, such as bacteria, viruses, heavy metal ions, organic matter, ammonia nitrogen, etc., significantly improving water quality. At the same time, reverse osmosis equipment also has a high recovery rate and water production volume and can meet most industrial and household water needs.
Environmental protection: Reverse osmosis equipment is a physical water treatment method that does not require the use of chemicals, so it will not produce secondary pollution, nor will it produce a large amount of wastewater and waste residue, and is environmentally friendly.
Strong reliability: Reverse osmosis equipment has high stability and reliability and can operate stably for a long time. In addition, the maintenance and repair of reverse osmosis equipment are relatively simple and easy to operate.
Improve water quality and taste: RO technology not only removes harmful substances but also improves the taste and smell of water, providing a better drinking water experience.
Ease of operation: ITHIIL RO systems are generally designed to be portable and easy to install and maintain without requiring complex expertise.
Comparison between reverse osmosis system and other water filtration systems
The purpose of buying a water purifier is to make drinking water safe, and the primary task of a water purifier is to filter the water source. Whether the filtration is clean or not should be ranked first. In terms of filtration effect, reverse osmosis water purifiers are better than ultra-high-efficiency water purifiers. The water purifier is more in line with the first standard of water purification.
Ultrafiltration water purifier: The filtration precision is 0.01 micron, which can filter colloids, rust, suspended solids, sediment, macromolecular organic matter, and other pollutants with a volume larger than 0.01 micron. However, bacteria and viruses smaller than 0.01 microns, calcium and magnesium ions in water, and heavy metals cannot be filtered out. There is almost nothing that can be done about chemical contaminants, and filtered water cannot reach the level of direct drinking. But it is no problem to use it for washing, cooking, boiling water, etc.
Reverse osmosis water purifier: The filtration accuracy is 0.0001 micron. It can completely remove bacteria, residual chlorine, colloids, organic matter, pesticides, inorganic salts, heavy metals, and other impurities in the water. In addition to the impurities that ultrafiltration can remove, it can also remove 95% to 97% of ions in the water. It is called a high-tech "artificial kidney" outside the body. The water filtered by the reverse osmosis water purifier is completely drinkable and tastes better.
Applicable scenarios of the RO system:
Reverse osmosis equipment is suitable for various water sources and treatment requirements, and can meet the needs of different fields, such as industrial water, drinking water, and sewage treatment;
Municipal water supply: Remove residual chlorine, odor, and potential pollutants in water to improve tap water quality.
Well water: Effectively remove common bacteria, viruses, heavy metals, and other pollutants in well water to ensure the safety of drinking water.
Other water sources: such as surface water, rainwater, etc., RO system can be used as a reliable means of deep purification.
The ITEHIL portable reverse osmosis water filtration system can easily filter rainwater, spring water, lake water, pond water, river water, sweat, urine, tap water, coffee, cola, etc., from ponds to rivers to streams, filtering various environmental water resources. ITHIIL enables fast and convenient water filtration at the source, portable water filtration has never been easier.
