Reverse osmosis pure water machine has become the mainstream of modern household water purification products. It adopts reverse osmosis membrane filtration technology, and only water molecules can pass through the reverse osmosis membrane as drinking water; Various pollutants such as scale, heavy metal ions, bacteria, water-soluble organic matter, and soluble salt ions cannot pass through the reverse osmosis membrane and are discharged as concentrated water. The reverse osmosis pure water machine ensures the safety and reliability of drinking water quality, and there is no problem of drinking water pollution.
The core component of reverse osmosis pure water machine is reverse osmosis membrane, which usually uses PP cotton filter and activated carbon filter as pretreatment. Under pressure, the pure water machine relies on reverse osmosis membrane components to filter and convert tap water into pure water. Its main parameters include water production rate, water production rate, and water quality. The unit of water production for a purified water machine is usually liters per hour (L/h) or gallons per day (GPD). The water production rate of a purified water machine refers to the ratio of the purified water produced by the machine to the raw water, usually expressed as a percentage. The high or low water production rate will affect the water efficiency and cost of the purified water machine. Generally speaking, a higher water production rate means that the same amount of raw water can produce more purified water, thereby saving water.
The purified water produced by the reverse osmosis pure water machine is fresher, more hygienic, and safer than bottled water. Increasing the area of the reverse osmosis membrane can improve the high water yield of the reverse osmosis pure water machine. Increasing operating pressure can also increase water production and water yield. Shandong Jinyu Membrane Technology Development Co., Ltd.'s household reverse osmosis membrane components have the characteristics of ultra-low pressure and high flux, and are suitable for various models of purified water machines.
Product specifications:
1. The test data is based on the following test conditions: the raw water is a 250 ppm NaCl solution, at 25 ℃, pH7.5, The operating pressure is 100 psi (0.69 Mpa), and the system recovery rate is 15%.
2. The tested water production of household reverse osmosis membrane components is the average value, and the error of water production of a single membrane component is within 15%.
Quality of water produced by reverse osmosis purified water machine
1. Extremely low impurities
After effective filtration and treatment, purified water removes most impurities such as suspended solids, sediment, organic matter, inorganic matter, and microorganisms.
2. Low conductivity
Conductivity is an indicator of the ion content in water, and the conductivity of purified water is usually low, indicating that there is less dissolved salt content in the water.
3. Neutral pH value
The pH value of purified water is generally close to neutral, between 6.5 and 7.5.
4. Aseptic
Purified water can achieve a sterile state.
