Many industrial plants' water treatment systems, operating for years, are facing the predicament of shrinking capacity, repeatedly exceeding effluent standards, high unit power consumption, and frequent forced shutdowns for maintenance. Rebuilding from scratch with a completely new production line would require hundreds of thousands of yuan in capital, coupled with a lengthy construction period, making it almost unbearable for companies rushing to fulfill orders. Xi'an DIEN Water Treatment has targeted this predicament, focusing on the R&D and production of water treatment equipment and the reengineering of complete machine processes to help customers customize and upgrade reverse osmosis equipment.
Reverse Osmosis Equipment
Water purification devices that have been in service for more than three years often experience malfunctions not from a single component, but from a complex interplay of problems such as pretreatment unit blockage, thinning of the delivery pipeline walls, electrical control logic malfunctions, and irreversible fouling of the reverse osmosis membrane modules. Simply replacing parts piecemeal often only addresses the symptoms, not the root cause, leading to recurrence after a few months. The DIEN team adheres to a systematic approach of "check-up first, then treatment": upon arrival, they conduct thorough pressure tests and water quality comparisons on the entire reverse osmosis unit to identify each performance bottleneck. Then, focusing on the core pain points, they optimize the process path, iterate key components, and rewrite control programs, bringing the equipment back to or even exceeding factory standards without altering the main framework.
The entire technical upgrade chain encompasses initial unit inspection, replacement of aging pipelines, gradient filling of filter media at each stage, selection and upgrading of membrane elements, disassembly and maintenance of high-pressure pumps, intelligent integration of PLC and frequency converter modules, joint commissioning of the entire system, and final acceptance and delivery. Subsequent services include annual managed maintenance and emergency repairs for unforeseen malfunctions. Whether for workshop cooling circulation, electroplating rinsing pure water, or boiler feedwater scenarios, the upgrade schedule can be matched accordingly, minimizing the owner's risk of water outages and financial burden.
A Case Study of the Lintong Machinery Processing Industrial Park
A precision parts manufacturing company in Lintong, Xi'an, had its original 10-ton/hour integrated reverse osmosis unit in operation for five years. Years of full-load operation led to a gradual decline in water output each quarter, frequent exceedances in pure water conductivity, high-pressure pump current spikes, and the need for weekly manual backwashing, forcing the production line to repeatedly limit production. Management initially planned to replace the entire unit, but after a rough cost estimate, they discovered a huge budget shortfall and a delivery delay of over three months.
Reverse Osmosis Equipment
After DIEN's engineers arrived on-site, they spent two days completing the pressure curve plotting and membrane sampling analysis for the entire unit. They then produced a special technical modification plan: "Preserving the framework, upgrading and improving performance." The frame and main structure were retained as is; all membrane elements were replaced with a new generation of low-pressure, high-flux, anti-fouling types; all aging O-rings, solenoid valves, and flow meters were replaced; the quartz sand and manganese sand in the filter tank were refilled with a new gradation; the original manually operated start/stop control cabinet was upgraded to a variable frequency intelligent control platform with remote monitoring; and the backwashing cycle and pressure threshold were recalibrated. The measured data after the modification was completed were encouraging: rated water production returned to 100%, pure water resistivity stably met standards, the overall power consumption per ton of water decreased by nearly 30%, and routine inspections are now only required quarterly, completely eliminating the nightmare of weekly disassembly and cleaning. The entire technical upgrade cost less than 40% of the purchase price of a new machine. The equipment operated without any unplanned downtime for over a year afterward. Following project delivery, DIEN Water Treatment immediately signed an annual maintenance agreement with the factory, sending personnel quarterly to conduct comprehensive inspections and pre-replacement of consumables to ensure the system is always in optimal operating condition.
DIEN Water Treatment, rooted in Xi'an, has long been familiar with the characteristics of industrial water quality in Northwest China and the "ailments" of various existing equipment. Even with the most challenging aging units, they can quickly pinpoint the problems and implement targeted solutions.
