In scenarios such as electronics, photovoltaic, precision manufacturing, and high-end laboratories with almost demanding water quality requirements, EDI ultrapure water equipment is the core level for producing 18.2MW·cm high-purity water.Many enterprise equipment will run for two or three years and will find that power consumption is rising, the loss rate of EDI modules is far faster than expected, and the discharge of concentrated water remains high. Over time, the cost of water, electricity and consumables has piled up into a lot of expenses.In view of the common pain points in this industry, Xi'an DIEN Water treatment specializes in the optimization and upgrading of energy consumption of EDI ultrapure water equipment, starting from the three dimensions of the underlying process improvement, the adaptation of working conditions and parameters, and the iteration of the intelligent control system. Under the premise that the effluent quality is fully up to standard, the long-term operating costs will be reduced, and the company will be able to reduce costs and increase efficiency.
EDI ultrapure water equipment
Most traditional EDI ultrapure water equipment on the market has its operating parameters welded to death when it leaves the factory. Regardless of fluctuations in raw water quality and actual water consumption, the water pressure and current maintain constant power throughout the process, and a large amount of electrical energy does useless work.In addition, the configuration of the pretreatment units of many equipment has shrunk, the water quality of the water inlet fluctuates greatly, the surface of the EDI membrane stack is slowly becoming thin, the operating resistance is getting higher and higher, the power consumption is rising, and the service life of the membrane (click to learn: How long is the service life of the reverse osmosis membrane) has been abruptly shortened.DIEN water treatment has been rooted in the northwest industrial water treatment market for many years. It has thoroughly understood the characteristics of high hardness and high TDS water quality in the north. Combined with the actual production conditions of different industries, it has made targeted energy-saving optimization plans, from pretreatment systems, power systems to intelligent control systems. The whole link adjustment not only preserves the stability of ultrapure water, but also cuts down on ineffective energy consumption.
Completely different from ordinary standardized models on the market, DIEN's optimized EDI ultrapure water equipment is equipped with a self-developed intelligent frequency conversion control system, which can automatically match the current and water inlet pressure in real time according to the raw water quality and instantaneous water consumption, and optimize the resin regeneration efficiency in the EDI module to avoid energy idling waste from the root cause; upgrade the high recovery rate cascade process, the concentrated water segment is refluxed and reused, the water resource utilization rate is greatly improved, and the wastewater discharge volume is directly reduced; with a multi-stage precision pre-filtration system, the calcium-magnesium ions and suspended solids that are easy to scale are intercepted and cleaned in advance, and the water inlet is protected from the source. The EDI membrane stack greatly reduces the equipment failure rate and the replacement cost of core components, and minimizes long-term operation and maintenance expenses from multiple dimensions.
Real energy consumption optimization and transformation case
Customer profile: An electronic components production enterprise in Xi'an High-tech Zone, the old EDI ultrapure water equipment put into use in the early years, after running for a few years, the water resistivity often fluctuates, which does not meet the production requirements, and the equipment consumes a lot of power, the recovery rate of concentrated water is low, and the monthly operation and maintenance costs of water, electricity and consumables are ridiculously high. The production line dare not stop casually, and a suitable optimization and transformation plan has not been found.

Customized optimization solution: DIEN's technical team came to the door for 72 consecutive hours to collect the full-time operation data of the equipment, accurately calibrate the water pressure of each section of the pipeline and the operating current of the EDI module, and gave customers a set of exclusive energy consumption optimization solutions that do not require major disassembly and major changes: upgrade the two-stage reverse osmosis equipment to completely smooth out the fluctuations in the water quality of the EDI inlet; replace the energy-saving high-pressure pump and the intelligent frequency conversion control system to dynamically adjust the operating power with real-time water consumption; recalibrate the operating current and voltage curve of the EDI module to adjust the resin regeneration parameters to the interval most suitable for working conditions; transform the concentrated water cascade reflow system to The standard concentrated water that was directly discharged before was recycled and reused, and the overall water recovery rate was greatly improved.The whole process is transformed while producing, without delaying the normal water consumption of the customer's production line.
Use effect and customer evaluation: After the optimization and transformation has been completed and put into use for half a year, the equipment has been operating stably throughout the process, and the resistivity of ultrapure water has been steadily maintained at 18.2MW·cm, which fully meets the stringent water standards for the production of electronic components.The overall power consumption of the equipment has been directly reduced by more than 25%, the recovery rate of concentrated water has been greatly improved, and the monthly operation and maintenance costs of water, electricity and consumables have been significantly reduced.Real customer feedback: "The energy consumption of old equipment was too high before, which has always been the old difficulty and pain point on our production side.DIEN's EDI energy consumption optimization plan is particularly practical this time. Normal production has not been delayed throughout the process, and the water quality of the effluent is more stable than before. Long-term operation can save a lot of operating costs. The local manufacturer's technology is hard enough, and the after-sales response is also very intimate.”
Whether it is the customization of new equipment or the energy-saving transformation, upgrade iteration, and operation and maintenance optimization of old EDI ultrapure water equipment, Xi'an DIEN water treatment can give you exclusive solutions that are fully adapted to your own working conditions, accurately matching the needs of ultrapure water in different industries such as electronics, photovoltaic, precision manufacturing, etc., to help enterprises achieve long-term energy saving and cost reduction.
