Many procurement and workshop technicians in the manufacturing and food processing industries often consult industrial reverse osmosis equipment when retrofitting production water systems.In industrial production, boiler water replenishment, raw material deployment of pure water, and workshop production of water purification are all inseparable from reverse osmosis equipment. It is also the most widely used water purification device in the field of industrial water purification treatment.Many factories originally relied on groundwater and tap water for direct production. The salt, sediment, and heavy metals in the water exceeded the standard, which frequently caused pipeline fouling and accelerated equipment loss. Replacing industrial reverse osmosis water treatment equipment can solve the problem of substandard water quality from the source.
Industrial reverse osmosis equipment
1. The core working principle of industrial reverse osmosis equipment
Many people have heard of reverse osmosis, but they don't understand the difference from ordinary filtration.Conventional filtration is that water spontaneously penetrates the filter material by gravity, while industrial reverse osmosis equipment relies on high-pressure drive to complete water purification.The equipment applies pressure through a high-pressure pump to break the natural penetration law of water molecules. Raw water passes through the ultra-fine pore size of the reverse osmosis membrane under pressure. Calcium and magnesium ions, salts, colloids, and microorganisms in the water are intercepted and trapped by the membrane. Only pure water molecules pass through the membrane smoothly, so as to achieve the separation of water and impurities.For a simple example, the mineralization of groundwater in many chemical plant areas in Northwest China is high, and the conductivity of raw water exceeds 2000µS/cm. After membrane screening and desalination, the salt removal rate can reach more than 98%. This is also the core logic of reverse osmosis desalination.The whole set of devices is equipped with an electronic control system, which can realize automated operation without special personnel on duty 24 hours a day.
2. The standard process flow of the complete set of equipment
A set of molded industrial reverse osmosis water treatment equipment follows a fixed assembly line process, from raw water to finished pure water, there are five links：
Raw water tank: store raw water into the factory to buffer fluctuations in water pressure and avoid instantaneous water flow hitting the rear filter element;
Pretreatment system: it includes quartz sand, activated carbon, and softening filter to filter out sediment, rust, and residual chlorine to protect the subsequent reverse osmosis membrane from being scratched and clogged.;
Precision filtration: 5µm security filter element does the final check to intercept fine impurities missed in pretreatment;
High-pressure pump + RO host: After the high-pressure pump is pressurized, the water body is fed into the reverse osmosis membrane element to complete the desalination and purification.;
Pure water tank: collect the output pure water and supply it to the boiler for water replenishment and production line water.
The whole process is designed in a closed loop, and the wastewater is collected and reused separately, which meets the production requirements of energy saving and environmental protection.

3. Differences in the selection of single-stage and two-stage reverse osmosis and applicable scenarios
The purchase of reverse osmosis equipment is often entangled in the selection of single and double stages, and the gap between the water quality of the two effluent and the applicable water source is obvious.Single-stage reverse osmosis equipment is suitable for tap water and low-mineralization surface water. The conductivity of conventional effluent is 10–50µS/cm, and it is mostly used for circulating cooling water and ordinary batching water; two-stage reverse osmosis equipment is used for reverse osmosis filtration again on the basis of primary water production, and the desalination effect is doubled. The resistivity of the effluent can be close to the standard of pure water, and the conductivity is generally lower than 5µS/cm.For example, two-stage must be used for the production of pharmaceutical and electronic components, while single-stage can be used for boiler water replenishment and food rough processing. Industrial reverse osmosis equipment manufacturers will customize models based on on-site raw water testing data.
4. Equipment advantages, water output indicators and multi-industry landing applications
(1) Reference standard for effluent quality
Conventional reverse osmosis water conductivity: single-stage 10~50µS/cm, two-stage 1~5µS/cm; drinking water level ≤10µS/cm, industrial high-purity pure water can be controlled within 2µS, raw water quality is the key to the final value.
(2) Core advantages and applications
The equipment mainly operates automatically, and the start-stop and flushing are all done independently by electronic control, and the replacement cycle of consumables is long; the wastewater can be recycled for ground flushing to achieve energy saving and environmental protection.At present, it is widely used in food and beverage, medicine, electroplating, thermal boilers, chemical raw material deployment and other fields. In the transformation projects of factories in many northwest regions, industrial water purification treatment basically gives priority to this equipment.
5. Factory customized services and landing after-sales
Reliable reverse osmosis equipment manufacturers choose our DIEN water treatment.DIEN will not apply standardized models. They are all customized according to the specifications of industrial reverse osmosis equipment after on-site survey of water sources and testing of raw water conductivity.From the design of the plan, on-site installation and commissioning, to the replacement of the filter element and membrane element in the later stage, the whole process of supporting after-sales, we can also do the nearest on-site maintenance for local customers, greatly shortening the equipment downtime and maintenance time, and reducing the loss of factory shutdown.
With the characteristics of stable desalination, low operation and maintenance costs, energy saving and environmental protection, industrial reverse osmosis equipment has become the equipment just needed for industrial water purification treatment.Distinguish between single- and two-stage models, control the details of the process flow, and then select regular industrial reverse osmosis equipment manufacturers to customize as needed, so that they can match their own production water standards, and avoid the root causes of poor water quality. Equipment loss, unstable product quality and other problems.
