1. Guide to the precise model adaptation of reverse osmosis equipment in all scenarios of chemical industry
The production volume, water purity standards, and raw water quality conditions of different chemical workshops are greatly different. Xi'an DIEN Water Treatment has built a complete equipment product matrix covering the full tonnage segment, which can accurately match the differentiated water needs of various chemical enterprises, large, medium and small, to avoid the problem of insufficient production capacity of "small cars" or redundant configurations that increase invalid inputs.：
For small-volume water use scenarios such as small chemical workshops and in-house laboratories, it is suitable for first-class reverse osmosis equipment of 5-20 tons/day. It occupies a compact space and is easy to install and debug. It fully meets the water standards for basic production cleaning and experimental reagent preparation.
For scenarios where the purity of pure water is required for fine chemicals, daily chemical production, etc., it is suitable for two-stage reverse osmosis equipment of 30-100 tons/day, which deeply filters out all kinds of impurities in the water, and the purity of the water produced is stable and up to standard, and it is suitable for the strict requirements of high-precision production processes.

For large-scale centralized water supply scenarios such as large-scale chemical industrial parks and 24-hour continuous production lines, large-flow production water reverse osmosis equipment of more than 100 tons/day can be customized exclusively. The redundant design of the system is sufficient to support long-term uninterrupted and stable water production and adapt to the rhythm of large-scale industrial production of water supply.
2. Core purchase points of chemical reverse osmosis equipment material, process, and configuration
Material selection points: The composition of raw water quality in chemical workshops is complex, and the proportion of strong corrosive media such as acid-base and high salt is high. The overall frame and internal water pipelines of the equipment must give priority to 304/316L food-grade stainless steel material, which is resistant to acid and alkali corrosion. Strong ability to prevent secondary pollution of water quality caused by material precipitation from the root cause.Ordinary UPVC pipelines can only be adapted to low-requirement scenarios for mild water purification, and high-impurity chemical production water treatment scenarios. All stainless steel anticorrosive materials must be selected to ensure the long-term stable operation of the equipment.
Process selection points: Standard reverse osmosis equipment for chemical production scenarios must adopt the core mature process of ”multi-media pretreatment + activated carbon adsorption filtration + precision security filter + two-stage reverse osmosis deep treatment", which can efficiently trap and remove heavy metal ions, dissolved salts, colloidal suspended solids, organic pollutants and other impurities in the water, and the overall desalination rate of the system can be stably maintained at more than 99%.If the raw water in the project location has high hardness and large turbidity fluctuations, an additional fully automatic softening pretreatment unit can be installed to avoid the common problems of fouling and clogging of reverse osmosis membrane components from the front end, and greatly extend the service life of membrane components.
Configuration selection points: All the core accessories of the equipment are selected from first-line brand products in the industry, and the reverse osmosis membrane is prioritized to be equipped with special anti-pollution membrane components from Dow and Heideneng. The high-pressure pump adopts industrial-grade products from leading brands such as Grundfos and Southern Pump industry to ensure that the equipment can support continuous and stable operation for 24 hours from the core component level; The whole machine is equipped with a fully automatic intelligent control system, which can realize real-time online monitoring of water quality parameters, regular automatic flushing of membrane components, and automatic fault alarms for abnormal working conditions. There is no need to arrange special personnel to be on duty full-time, greatly reducing long-term labor operation and maintenance costs.

3. Customized project landing cases and real use feedback
Landing project: Upgrading and upgrading project of production water for a fine chemical workshop in Xi'an, Shaanxi Province
The treatment process of the old water purification equipment previously put into use by the enterprise is simple, and the purity of the final water produced is completely not up to the production standards of fine chemicals, and the equipment frequently fails and shuts down.Long-term operation and maintenance costs remain high, which seriously affects the product yield.After several rounds of comparison of the field cases and process capabilities of a number of reverse osmosis equipment manufacturers, the company finally selected Xi'an DIEN Water Treatment as the project partner.
The technical team combined with the actual peak water flow rate of the workshop, the raw water quality test report, and the exclusive production standards of fine chemicals to tailor an exclusive solution for the 80-ton/day two-stage reverse osmosis production water equipment.The whole set of equipment is made of 316L grade anticorrosive stainless steel, which is perfectly adapted to the complex corrosive water quality conditions of the chemical industry; it is upgraded with special anti-pollution reverse osmosis membrane components, and the front-end pretreatment process is optimized simultaneously to eliminate the common industry problems of frequent clogging of membrane components from the root cause; it is equipped with a full-link automatic intelligent control system to truly realize unattended automatic operation, and at the same time, the layout of the internal pipeline of the equipment has been compactly optimized, which greatly saves valuable floor space in the workshop.
Since this set of customized reverse osmosis equipment has been officially put into use for half a year, the whole process has been in stable operation, there have been no unplanned failures and shutdowns, and the indicators of the water quality of the water produced have continued to meet the standards stably, fully matching the demanding production water needs of fine chemicals.
Customer's real use evaluation: “I compared many water treatment manufacturers before and after. The equipment configuration of DIEN water treatment did not cut corners. The process plan fully fits our actual working conditions and accurately solves the problem of substandard production water that has plagued us for a long time. The overall energy consumption of the equipment is low, the daily operation and maintenance are very simple, and the after-sales team responds quickly. It is the top manufacturer of water reverse osmosis equipment in the Northwest region. We will continue to choose long-term cooperation for subsequent new projects.”
