The process flow of single-stage reverse osmosis equipment:

1. Pre treatment: Pre treatment of raw water to improve water quality, meet requirements, reduce membrane fouling, and increase its service life. Mainly deals with microorganisms, colloids, organic matter, heavy metal ions, solid particles, and free chlorine in the influent. To meet the requirements of water inlet for single-stage reverse osmosis equipment and ensure long-term stable operation of the reverse osmosis device.

It consists of a sand filter, a carbon filter, a water softener, and a precision filter.

Sand filter: removes sediment, impurities, and suspended solids, reducing the pollution index density of raw water.

Carbon filter: It has two functions: adsorption and filtration. Filter out chemical organic compounds, heavy metals, chromaticity, odor, and residual chlorine from tap water to improve water quality. Security filter, 5 micron PPF filtering element, intercepts objects larger than 5 microns, and increases the service life of the membrane.

2. Single stage reverse osmosis equipment: The separation pore size of the membrane is 10-6cm-10-7cm, which can remove organic substances (such as trihalomethane intermediates, colloids, suspended solids, microorganisms, algae, fungi, etc.), heat sources, viruses, and other substances in water. After deep separation of the first three stages of pre-treatment water by the reverse osmosis membrane host, water that is beneficial to human health can pass through, which is not conducive to human health. The produced pure water enters the pure water tank; The online conductivity indicator can dynamically display the water quality status of clean water production at any time. A high-pressure pump provides the working pressure of the membrane through water to maintain water production. The water treatment system is a single-stage reverse osmosis system.

3. Single stage reverse osmosis equipment control function description: The system changes the corresponding output signals of the intake valve, high-pressure pump, flushing valve and other executing components based on changes in input signals such as high pressure, low pressure, liquid level, reset, and switch, achieving automatic control of the standard reverse osmosis system, pressure protection, liquid level control, opening/full water/automatic flushing and other functions.
