1. The full tonnage price range of industrial reverse osmosis desalination units
Industrial-grade seawater desalination equipment is a typical non-standard customized equipment. There is no unified fixed selling price. The core of the final pricing is determined by the four core dimensions of daily treatment tonnage, anti-corrosion material of the fuselage, automation operation level, and final effluent water quality standard.Combined with the public quotation of the domestic industrial water treatment market in 2026. the price stratification of reverse osmosis desalination units is clear and clear, which can cover the budget needs of projects of different sizes.：
Desalination equipment
Small industrial-grade units (daily processing of 1-10 tons): suitable for small coastal processing plants, remote island base stations, and small offshore operating sites. The market price range of basic anti-corrosion configuration models is 20 million-50.000 yuan. It focuses on lightweight installation and low operation and maintenance thresholds, and can be quickly put into use.
Medium-sized industrial-grade units (daily processing of 10-100 tons): suitable for ports and docks, aquatic product processing enterprises, and small and medium-sized coastal manufacturing plants. The price range of mainstream models equipped with fully automatic operation systems is 50.000-200.000 yuan, which can achieve 24-hour continuous and stable water production to meet the demand for water for production during the whole period.
Large-scale industrial-grade customized units (daily processing of more than 100 tons): suitable for large-scale chemical parks, coastal power stations, and contiguous coastal industrial parks, customized models with two-stage reverse osmosis + full anticorrosion and high-configuration technology, with a market price range of more than 200.000 yuan, can support large-scale centralized water supply, and strong long-term operating stability.
Xi'an DIEN Water Treatment will strictly eliminate redundant and non-essential configurations during the customization process, and accurately match the actual water needs of the project, so as to create a cost-effective and exclusive pricing plan for customers to avoid invalid budget investment.
2. Equipment selection guide for precise adaptation by industry scenario
" "The average daily water consumption, effluent quality requirements, and on-site installation conditions of different industrial scenarios are very different. Targeted selection can not only directly reduce the subsequent long-term operation and maintenance costs, but also greatly improve the water purification operation efficiency of the reverse osmosis system, avoiding the problem of “overkill” or “insufficient production capacity”.
Supporting scenarios for aquatic product processing and coastal homestay: The overall water demand is too small, and the water quality of the effluent can meet the standards of production, cleaning and daily use. Priority is given to small reverse osmosis seawater desalination units of 2-10 tons/day. The overall equipment occupies a very small area, and there is no need for complex infrastructure transformation. On-site water and electricity can be installed and debugged quickly.
Port terminal and ship operation and maintenance scenarios: The water supply is required to be uninterrupted throughout the process, suitable for medium-sized seawater desalination equipment of 20-50 tons/day, equipped with a fully automated operation control system, without special personnel on duty 24 hours a day, it can achieve 7×24 hours of uninterrupted and stable water production, which fully matches the water supply rhythm of continuous port operations.
Scenarios of chemical industry, electric power, and coastal industrial parks: The average daily water consumption is extremely large, and the purity of the effluent water quality is strictly required. It is suitable for large-scale industrial seawater desalination equipment of 100 tons/day and above, and adopts a two-stage reverse osmosis deep treatment process. The overall desalination rate of the system can be stable to more than 99%, and the effluent fully meets the stringent water standards of high-end industrial production.

3. Customized landing solutions and real project cases
Landing project: production water upgrade project of a coastal aquatic processing plant in Qingdao, Shandong Province
The simple water purification device previously put into use by the factory is completely unable to adapt to the high-salinity offshore seawater conditions. Incomplete seawater purification directly affects the quality of the final product of aquatic product processing. At the same time, the equipment failure rate remains high, and the long-term operation and maintenance costs continue to rise, which seriously slows down the pace of production.The technical team of Xi'an DIEN Water Treatment went to the project site to complete the on-site survey as soon as possible, accurately calculated the peak fluctuation range of the plant's production water, and finally tailored the overall solution for the whole process of 50 tons/day reverse osmosis seawater desalination equipment.
The fuselage of the complete set of equipment is all made of high-strength duplex stainless steel anticorrosive material, which is perfectly adapted to the highly corrosive environment of high salt spray in coastal areas, greatly prolonging the overall service life of the equipment; it is equipped with a cloud-linked automatic intelligent control system, which supports one-key start and stop, real-time online monitoring of water quality parameters, and automatic trigger warning of abnormal working conditions; the front end is equipped with a multi-stage precision pretreatment unit, and the back end is equipped with a two-stage reverse osmosis deep filtration process, which can fully filter out salt, suspended impurities, and various microorganisms in seawater, and the final effluent quality fully complies with national industrial production water standards.At the same time, the technical team optimized the hydrodynamics of the internal pipeline layout of the equipment, which greatly reduced the energy consumption of the system operation and directly reduced the comprehensive cost of subsequent long-term operation and maintenance.
4. The actual operation effect of the project and the real feedback from customers
The set of customized seawater desalination equipment has been officially put into use for one year, and the whole process has been in stable operation. There have been no unplanned failures and shutdowns. The desalination rate of the system's seawater has always been stable at more than 98.5%, and the indicators of effluent quality continue to meet the standards, fully covering all the water needs of the factory's daily production and equipment cleaning.The degree of automation of the equipment is extremely high, and there is no need to arrange special personnel to be on duty full-time, which directly significantly reduces the labor operation and maintenance costs; compared with the old water purification equipment previously used, the comprehensive energy consumption of the entire system is reduced by about 20%, and the economic advantages of long-term operation are very prominent.
