In recent years, ecological and environmental problems have not been effectively addressed. With the development of the industrial sector, the requirements for industrial water are becoming increasingly stringent. Many industrial processes require the use of water, and the quality requirements for this water are often higher than that of ordinary tap water, thus giving rise to the industrial water treatment industry. Industrial reverse osmosis water purification equipment can produce pure water systems specifically for product manufacturing in fields such as microbiology, pharmaceuticals, and medical equipment cleaning, and has gained increasing recognition from consumers. However, many users have a weak awareness of the maintenance of industrial reverse osmosis water purification equipment, resulting in unnecessary losses during later use. A reverse osmosis pure water treatment system generally includes a pretreatment system, a reverse osmosis device, a post-treatment system, a cleaning system, and an electrical control system, etc.

I: Timely replacement of consumables in the pretreatment section

Detailed classification description of the pretreatment system of industrial reverse osmosis water purification equipment:

1. Multi-media filters mainly remove suspended solids, colloidal solutions, fine sand, clay, decaying plants, and fine particles from the water. It can reduce water turbidity, achieve the effect of water body response, and protect the RO reverse osmosis membrane.

2. Activated carbon filters mainly use a large number of methyl (hydroxyl) and alkyl groups on the surface of activated carbon to carry out chemical adsorption of various chemicals, removing odors, organic compounds, colloidal solutions, iron, and redox potential from the water, thereby reducing water turbidity and haziness, and minimizing environmental pollution of the reverse osmosis system.

3. Water softening equipment uses potassium ions in the ion exchange column to exchange chlorites in the water, reducing water hardness, and regenerating the ion exchange resin with soft water salt. Soft water salt is also known as an ion exchange resin regenerant.

4. Precision filters generally use 5-micron PP cotton filter elements, mainly to remove particles larger than 5 microns that were not removed in the previous treatment system, intercepting filter materials lost in the previous three filtration processes, thereby protecting the RO membrane and increasing the lifespan of the reverse osmosis membrane. Whether the filter element can meet the normal operating conditions will affect the normal operating conditions of the membrane. Generally, the filter element should be replaced every 3-4 months.

II: Avoid direct sunlight

Regardless of the type of water recovery device, care should be taken to avoid direct sunlight during use, as sunlight can promote the growth of algae. Proper maintenance of industrial reverse osmosis water purification equipment is essential. If it must be placed in an area that is not exposed to direct sunlight, it is best to build a shading cover or partition around the industrial reverse osmosis water purification equipment, which can prevent algae growth.

III: Avoid heat sources

If the industrial reverse osmosis water purification equipment is too close to an electric water heater, long-term baking will affect the service life of plastic parts.

IV. Reverse osmosis system maintenance

1. Conduct daily water quality testing and record equipment operating parameters, and promptly address any abnormalities. Regularly check and record important parameters such as pure water conductivity, pressure at various points, and inlet and outlet water flow.

2. Regularly add regenerant to the salt tank, setting the regeneration time based on actual site conditions and water production. Generally, it is added once every 3-4 days.

3. Replace the security filter cartridges in a timely manner. (Generally replaced every 3-6 months)

4. Regularly wipe the machine to keep the equipment clean.

5. Regularly check the pipelines for leaks and address them promptly.

6. Ensure the normal water and power supply of the equipment. In case of special circumstances such as power or water outages, the equipment needs to be readjusted, especially the regeneration time needs to be reset after a power outage. Unauthorized personnel are prohibited from touching the buttons of the electrical control part and the valves of the pipeline part to prevent misoperation and prevent the equipment from operating normally.

V. Emergency measures When the equipment is powered off or the main pump, membrane, or other components that produce pure water are damaged and cannot produce pure water, the softened water valve can be opened to continue using softened water to ensure the normal operation of the water-using equipment. This method should be based on the actual requirements of the water-using equipment.

1. If the equipment leaks severely, immediately turn off the equipment's water inlet switch and power, and notify the service provider for handling.

2. During water production, if the post-membrane pressure gauge shows more than 1.5 MPa, the conductivity exceeds 15 us/cm, or the produced water quality exceeds the standard range, the resin, membrane, activated carbon, and other consumables should be replaced in time.
