IONPURE LX-Z CEDI System Continuous Electrodeionization for Pharmaceutical & Industrial Deionized Water System

　　Ionpure LX-Z is an industrial continuous electrodeionization system engineered for high-purity deionized water production without chemical regeneration.Operating on RO permeate feed≤40μS/cm,this industrial deionized water system delivers 7–17 MΩ·cm resistivity at 90–95%water recovery.Suited for power generation boiler makeup,electronics rinsing,and pharmaceutical purified water loops.

　　What Is a Continuous Electrodeionization System?

　　A continuous electrodeionization(CEDI)system is a water purification technology that removes ionized species from RO permeate using ion exchange resins,ion-selective membranes,and a DC electric field.Unlike conventional mixed-bed deionizers,a CEDI module regenerates its ion exchange resins continuously in-situ using water dissociation(H⁺and OH⁻generation),requiring no chemical injection or downtime for regeneration.

　　The Ionpure LX-Z is a plate-and-frame industrial CEDI system employing a“Full-Fill”concentrate compartment design—the entire concentrate chamber is packed with ion exchange resin and separated by dual O-ring sealed membranes.This configuration provides robust electrical insulation and operational stability under industrial steam and power plant conditions.

　　Technical Highlights

　　Full-Fill concentrate chambers eliminate stagnant zones found in traditional screen-type CEDI designs.Every flow path within the concentrate compartment is packed with ion exchange resin,which enhances electrical conductivity uniformity across the entire membrane surface.This uniform current distribution suppresses localized scaling and improves long-term silica removal stability.

　　Dual O-ring sealing provides redundant leak protection at each internal junction.Each membrane and spacer interface is sealed twice,reducing the risk of product water contamination from concentrate stream leakage—an especially important consideration when producing water for high-pressure boiler makeup or semiconductor fabrication where trace ion intrusion triggers costly corrosion or yield loss.

　　No chemical regeneration and zero hazardous wastewater discharge.The LX-Z regenerates continuously using electrochemically generated H⁺and OH⁻ions,eliminating the need for hydrochloric acid or sodium hydroxide storage,neutralization tanks,and regeneration skid infrastructure.Operating cost is limited to electrical power consumption and periodic module replacement.

　　In-situ regeneration maintains continuous product water delivery.System downtime for resin exchange or chemical regeneration is eliminated.For applications such as 24/7 turbine operation or continuous pharmaceutical purified water circulation,uninterrupted output is a non-negotiable operational requirement.

　　Applications

　　Power plant boiler feedwater polishing:Produces makeup water with<0.1μS/cm conductivity and>10 MΩ·cm resistivity after RO pretreatment.Silica removal reaches 99%,directly reducing silica carryover to steam turbines and extending turbine blade cleaning intervals.

　　Semiconductor and electronics ultrapure water pretreatment:Serves as the primary deionization stage before mixed-bed polishing or UV/TOC destruction in microelectronics rinse water loops.The 90–95%recovery rate reduces upstream RO system sizing and wastewater volume compared to conventional ion exchange trains.

　　Pharmaceutical purified water(PW)and water for injection(WFI)pretreatment:Maintains consistent effluent conductivity under USP<645>compliance monitoring.Continuous operation without chemical regenerant handling simplifies validated state maintenance in GMP-regulated environments.

　　Chemical and petrochemical process water:Delivers high-purity water for catalyst makeup,reactor cooling,and product washing stages where trace ion contamination affects process yield or product specification compliance.

　　General industrial boiler makeup and humidification:Replaces manual mixed-bed polishers in facilities lacking on-site chemical handling permits or wastewater neutralization capacity.System footprint is limited to module stack,DC rectifier,and control panel dimensions.

　　Selection Guidance

　　Suitable installations:

　　Industrial facilities with existing RO pretreatment producing permeate<40μS/cm and seeking to eliminate acid/caustic handling and regeneration labor

　　Continuous 24/7 operation processes where offline regeneration windows are unavailable or expensive(power generation,continuous manufacturing,validated pharmaceutical loops)

　　Greenfield plant designs aiming for wastewater minimization and zero liquid discharge(ZLD)compatibility—the 90–95%recovery ratio is achievable with concentrate recycle to RO feed

　　Not recommended for:

　　Feed water exceeding 40μS/cm inlet conductivity.High TDS RO permeate or direct softened water feeding will exceed module ionic load capacity and depress product water resistivity below 7 MΩ·cm.Install a polishing RO stage or select a high-temperature,high-TDS CEDI module variant.

　　Applications requiring>18.2 MΩ·cm ultrapure water without downstream polishing.The LX-Z delivers 7–17 MΩ·cm;for Type E-1.3 or SEMI Grade 1 ultrapure water,install a mixed-bed deionizer,UV oxidation,or final ultrafiltration stage downstream of the CEDI module.

　　Outdoor environments exposed to direct sunlight or ambient temperature exceeding 45°C are not recommended.Install the module in a mechanical room,water treatment building,or within an insulated enclosure with ventilation.Sunlight exposure accelerates polymeric membrane degradation and promotes biological fouling.

　　FAQ

　　1.What is the price range and cost of ownership for an Ionpure LX-Z system?

　　An LX-Z CEDI system configured with module,rectifier,and control panel typically ranges from 35,000to120,000 USD depending on module model,flow rate,and control instrumentation scope.Prices fluctuate due to exchange rates,tariffs,and factory adjustments.For an accurate quotation with current lead time and technical proposal,contact Beijing Zhongping Technology directly.A common concern for procurement is the total cost versus mixed-bed DI systems:the LX-Z eliminates annual expenditure on hydrochloric acid,sodium hydroxide,and regeneration labor,producing a payback that many power and semiconductor plants realize within 2–3 years based on avoided chemical handling costs alone.

　　2.How do I select the correct LX-Z model for my required flow rate and water quality?

　　Model selection is determined by required product water flow rate(LPM or GPM),target resistivity,and inlet RO permeate conductivity.The six available models—LXM04Z,LXM10Z,LXM18Z,LXM24Z,LXM30Z,and LXM45Z—span a scaling range in module length and membrane active area.Provide your design flow rate,inlet conductivity,and target product water specification,and Beijing Zhongping Technology provides a model recommendation with a calculated achievable resistivity and recovery at your operating conditions.

　　3.What is the typical delivery time or lead time for Ionpure LX-Z modules and systems?

　　We dispatch LX-Z modules from stock within 1–2 weeks for common models.Complete CEDI systems with rectifier panels and interconnection piping have a standard lead time of 8–12 weeks,depending on system complexity and custom control panel fabrication.We provide a confirmed delivery schedule upon purchase order acceptance.

　　4.Is the LX-Z compatible with existing RO systems,and what inlet water quality is required for reliable operation?

　　Compatibility requires that the RO permeate meets the minimum inlet water quality requirements:conductivity<40μS/cm,silica<1.0 ppm,hardness<1.0 ppm as CaCO₃,free chlorine<0.02 ppm,temperature 5–45°C,and inlet pressure 1.4–7 bar.If your existing RO system produces permeate outside these limits,we specify pretreatment upgrades—such as cartridge filtration,activated carbon dechlorination,or a second-pass RO—as part of the project scope.Many procurement inquiries ask whether a CEDI can be retrofitted to an existing RO skid;the answer depends entirely on the RO permeate quality and available room for module mounting.

　　5.How many CEDI modules do I need,and what are the physical dimensions and mounting requirements?

　　Module quantity scales with flow rate and operating flux.The LXM module footprint ranges from 257.0 mm to 907.3 mm length(L dimension)and 146.8 mm to 747.7 mm centerline distance(C dimension)per module.Modules mount vertically in a rack or frame system,indoors,away from direct sunlight,with ambient temperature≤45°C and clearance for electrode and hydraulic connections at each end.Beijing Zhongping Technology provides a dimensioned general arrangement drawing with the quotation for your review and mechanical integration planning.

　　6.What certifications,test reports,and quality standards does the Ionpure LX-Z carry?

　　The LX-Z module is manufactured under an ISO 9001 and ISO 14000 certified quality and environmental management system,carries CE marking for European compliance,and holds Halal certification.Each module is factory hydrostatically tested and electrically tested,with a factory acceptance test(FAT)report available upon request.Many engineering and procurement specification packages require these certificates;we provide the certificate package at no cost during the bidding phase.

　　7.What is the typical power consumption and operating cost per cubic meter of product water?

　　The LX-Z module operates on a 0–300 VDC,1–6 A DC power supply.Actual power consumption varies with feed conductivity and target product resistivity but is typically in the range of 0.2–0.5 kWh/m³of product water.Compared to thermal regeneration methods or off-site resin regeneration services,the energy consumption is a fraction of conventional DI operating cost.The 90–95%water recovery rate also minimizes raw water and wastewater discharge costs;for applications where inlet water or discharge fees are significant line items,this recovery directly affects the operating budget.

　　8.How does the LX-Z compare to a conventional mixed-bed DI system in terms of total cost,maintenance,and operational complexity?

　　The LX-Z eliminates chemical storage,pH neutralization,regeneration labor,and periodic resin replacement that a mixed-bed system requires.A mixed-bed system incurs recurring costs for 30%hydrochloric acid and 50%sodium hydroxide,safety showers,chemical containment,and neutralization tank maintenance.The LX-Z replaces all these consumables and infrastructure with a single DC electrical power input.Some initial cost differential exists—CEDI capital outlay can be higher than a mixed-bed vessel and resin fill depending on system size—but the operating cost crossover point is typically 12–36 months for plants running continuous shifts.We provide a comparative lifecycle cost analysis with the quotation so you can evaluate this directly against your annual opex budget.

　　9.What is the warranty period for the LX-Z module and what amperage/voltage limits apply?

　　We provide a standard 1-year warranty on LX-Z modules and a 2-year warranty on rectifier power supply panels.Warranty coverage is contingent on operation within the published operating limits:0–300 VDC,1–6 A,and inlet water specifications as defined in the manufacturer datasheet.Operation at excessive voltage beyond the electrochemical window causes accelerated membrane degradation,which the warranty does not cover.Beijing Zhongping Technology provides commissioning supervision as part of system delivery,ensuring that rectifier setpoints are correctly established at startup and documented.

　　10.How do I get a detailed spec sheet,datasheet,and formal quotation for the LX-Z series or a specific model?

　　We send the official LX-Z module datasheet,dimensional drawings,and a system specification package by email within 24 hours of receiving your inquiry.To request a quotation,provide your required product water flow rate,inlet RO permeate conductivity,target water resistivity,and any site-specific mechanical or electrical standards.Contact Beijing Zhongping Technology with your project specifications and we return a technical and commercial proposal with scope of supply,specific model recommendation,and delivery timeline.
