Xi'an DIEN Water Treatment has been deeply rooted in the Northwest water treatment industry for many years, and is considered a well-known manufacturer of customized industrial pure water equipment in Xi'an. They manufacture equipment in their own workshop, and their technical team specializes in custom-designed reverse osmosis pure water systems—suitable for challenging environments such as narrow factories, hard well water, fluctuating water consumption, and high hygiene standards in food processing plants. DIEN can handle all these situations that would otherwise be difficult for general-purpose machines. From on-site water sampling and testing, drawing up piping diagrams according to the site, adjusting process levels, modifying tank diameters, and configuring intelligent control modules, to factory delivery and installation, and annual maintenance, they handle everything themselves. Their local Northwest warehouse maintains year-round stock, ensuring spare parts are readily available, and after-sales service doesn't require waiting for express delivery across provinces.
DIEN Industrial Pure Water Equipment Supports Customization
The standard reverse osmosis pure water unit features a multi-media filter base, activated carbon adsorption of organic matter, a softening unit to suppress calcium and magnesium, the RO main unit as the main support, a sterile water tank as the bottom support, and ultraviolet lamps for final sterilization. This complete process effectively blocks heavy metals, sediment, colloids, residual chlorine, and bacteria, ensuring stable conductivity of the produced water and providing uninterrupted industrial water supply. DIEN, a Xi'an-based manufacturer specializing in customized industrial pure water equipment, differs from others by offering free on-site water sampling and testing beforehand. They avoid simply copying solutions from computer templates, proactively addressing issues like membrane blockage, water quality drift, and equipment incompatibility in the workshop. The entire unit's tank and piping are made of 304 food-grade stainless steel, and core membrane components are selected from top-tier brands. A one- to three-year warranty is clearly stated in the contract, ensuring manageable maintenance costs.
Case Study: Well Water to Pure Water Upgrade at a Processing Plant in Xinyang, Henan
Pain Points Before Upgrade
A mechanical parts factory in Xinyang relied entirely on its own groundwater for production and cleaning. The iron and manganese levels were extremely high, the hardness was at its limit, and the TDS value (click to learn more: What causes high TDS in reverse osmosis equipment?) was consistently above 480. Parts left a white film on their surfaces after washing, resulting in mountains of defective products. The circulation pipes and cooling water tanks developed a hard crust every month, requiring acid washing every time production stopped. Consumables and losses due to downtime exceeded 10.000 yuan monthly. Adding to this, the cost of purchasing bottled pure water and transporting it to the workshop was exorbitantly high, making it impossible to sustain 24/7 production.
Customized Solution from DIEN Water Treatment
The technical team drove to the factory to collect water samples. Addressing the three major challenges—excessive iron and manganese levels, extremely high hardness, and a small area of bare ground in the workshop—they tailored a non-standard unit consisting of a pre-filter for iron and manganese removal, a softening pretreatment system, and a single-stage reverse osmosis pure water system. The machine body is compactly arranged to utilize the remaining space, with modular assembly that saves space. The control program incorporates automatic backwashing logic, eliminating the hassle of frequent manual maintenance.
Post-Modification Results
The TDS of the effluent is consistently below 30. workpieces are thoroughly cleaned without scale residue, and the defect rate has dropped by 75%. Pipelines are completely free of scale buildup, eliminating the monthly acid washing process, saving over 130.000 RMB annually in water and maintenance costs.
Customer Feedback: We had previously contacted several companies, who immediately presented standard machine drawings, which were too large for our workshop, requiring wall demolition and remodeling. DIEN measured our remaining space and directly modified the equipment dimensions. The water quality was perfect from the start, the machine runs automatically without supervision, and we no longer worry about water supply during peak seasons.

Case Study: Customized Dual-Stage Reverse Osmosis Pure Water System for a Beverage Factory in Zhengzhou, Henan
Preliminary Water Problems
A local beverage factory in Zhengzhou had installed a simple water purification unit years ago. However, during the rainy season, the surface water quality fluctuated, with frequent exceedances in total bacterial count and persistently high hardness. This resulted in inconsistent sweetness and acidity between batches of beverages, leading to a backlog of returns and repeated warnings from the quality control department. A pure water preparation system meeting food-grade standards was urgently needed to save the situation.
DIEN Water Treatment Implementation Solution
Adhering to the food safety red lines of the beverage industry, a customized 20-ton/hour dual-stage reverse osmosis system was installed. All piping is made of sanitary-grade stainless steel, with ultraviolet light and microporous terminal filtration added at the end. An online water quality monitoring instrument was also installed to monitor data in real time. The concentrated water is not wasted; it is used to flush the factory floor, significantly increasing water utilization. Several bottling lines can be supplied with water even when calling simultaneously.
Production Performance
The dual-stage reverse osmosis desalination rate remains stable above 98%, with effluent meeting food and beverage pure water standards. Water quality remains consistent throughout the year, resulting in a visibly improved taste in beverages, and the system passed food factory inspections on the first try.
Customer Feedback: DIEN Water has been reliable throughout the entire process, from sampling and measurement in the workshop to machine setup. In the two years since its launch, there haven't been any major problems. Monthly maintenance involves only a few steps, making it very worry-free. With stable water quality, product reputation has increased. Customized machines are definitely more efficient for our production line than buying ready-made ones.
As a reputable manufacturer of customized industrial pure water equipment in Xi'an, DIEN Water Treatment's non-standard reverse osmosis customization services extend to industrial water treatment projects throughout Shaanxi Province and neighboring provinces such as Henan, Gansu, and Shanxi. Whether it's upgrading and expanding existing systems, producing pure water from high-hardness well water, customizing food-grade water purifiers, or small integrated machines, DIEN's technical team can provide a customized solution tailored to the specific needs of the enterprise, using equipment that is practical and suitable for the site to reduce the overall water costs.
