With the development of urbanization, urban water resources are becoming increasingly scarce, and water pollution is also showing a serious trend. In order to solve this problem, reverse osmosis water generators have emerged as the times require. Reverse osmosis water generator is a device that reversely permeates water through high pressure and filters out most of the pollutants. Currently, reverse osmosis water generators have become a common method for solving drinking water problems in many households and enterprises. This article will introduce the basic principle and processing flow of the reverse osmosis water making machine in detail.
1、 Basic principle of reverse osmosis water generator
The basic principle of a reverse osmosis water generator is to filter water using a high-precision filter membrane called a reverse osmosis membrane (RO membrane). Reverse osmosis membrane is a material that separates water molecules through the difference in pore size. Its pore size is only 0.0001 microns, making it one of the most precise filtration membranes in the world. During the processing of a reverse osmosis water generator, water is first pretreated with an activated carbon filter element to remove impurities such as residual chlorine and odor. Then, through high pressure, water is reverse osmosis into the interior of the reverse osmosis membrane, and most of the pollutants (such as heavy metals, bacteria, viruses, organic substances, etc.) will be filtered out to obtain pure water.
2、 Processing process
The processing process of the reverse osmosis water generator mainly includes pretreatment, water inflow, pressure rise, filtration, wastewater discharge, and other links. The specific process is as follows:
1. Pretreatment: including quartz sand, activated carbon, and softeners, which can remove most impurities and odors from water and improve water filtration efficiency.
2. Inlet water: The pretreated water is fed into the reverse osmosis filter element.
3. Pressure increase: Increase the flow rate and water pressure of water through the pressure enhancement pump, enabling water to pass through the reverse osmosis filter element and produce effective filtration effects.
4. Filtration: Inside the reverse osmosis filter element, filtration is performed through a high-precision reverse osmosis membrane, and most impurities will be filtered out during the process.
Wastewater discharge: Certain wastewater will be generated during the processing of reverse osmosis water making machines, and it needs to be discharged.
