Veolia ZW1500 Discontinuation Notice & Replacement Model (ZW1500-X) Specification

 Veolia ZW1500 Discontinuation Notice & Replacement Model (ZW1500-X) Specification

As a global leader in water treatment solutions, Veolia is committed to continuous technological innovation and product optimization to better meet the evolving needs of customers and environmental challenges. This official document serves to notify all valued customers, partners and stakeholders that the ZeeWeed 1500 series model ZW1500 has been officially discontinued. The exclusive replacement model, ZW1500-X, inherits the core advantages of the ZW1500 while integrating upgraded technologies and optimized performance, ensuring seamless transition and enhanced operational value for all applications previously served by the ZW1500.

1. Discontinuation Announcement of ZW1500

After careful evaluation and technological iteration, Veolia has made the strategic decision to discontinue the production of the ZW1500 ultrafiltration membrane module, effective immediately. This decision is driven by our commitment to providing more efficient, reliable and cost-effective water treatment solutions, as well as the continuous advancement of ultrafiltration membrane technology.

Key notes on the ZW1500 discontinuation:

•          Production of ZW1500 has been officially ceased; no new orders for ZW1500 will be accepted.

•          Veolia will continue to provide after-sales support, including maintenance services, replacement parts (while supplies last) and technical consultation for existing ZW1500 installations, to ensure the normal operation of customer systems.

•          For all future projects and replacement needs previously suited for ZW1500, the ZW1500-X is designated as the exclusive, direct replacement model, ensuring full compatibility and superior performance.

2. Overview of Replacement Model: ZW1500-X

The ZW1500-X is specially developed by Veolia as the direct replacement for the discontinued ZW1500. Based on Veolia's proprietary PVDF (polyvinylidene fluoride) hollow fiber technology, the ZW1500-X maintains the same core application scope and installation compatibility as the ZW1500, while incorporating upgraded materials, structural optimization and enhanced operational efficiency. It is a pressurized ultrafiltration (UF) membrane module designed for outside-in filtration, widely applicable to drinking water treatment, tertiary filtration, and RO pretreatment for brackish water and seawater, delivering superior effluent quality that meets or exceeds global regulatory requirements.

Like the ZW1500, the ZW1500-X adopts an outside-in filtration mode, which ensures uniform flow distribution and high solids tolerance, reducing pretreatment requirements – a key advantage inherited from the original model. Additionally, it retains the same nominal pore diameter of 0.02 µm, ensuring optimal removal of particulates, bacteria, and viruses, consistent with the reliable performance customers have come to expect from Veolia's ZeeWeed series.

3. Key Advantages of ZW1500-X Over Discontinued ZW1500

As the upgraded replacement, the ZW1500-X not only achieves full compatibility with the ZW1500 but also offers significant performance improvements, bringing greater operational value to customers. The detailed comparisons and advantages are as follows:

Specification Category	Discontinued Model (ZW1500)	Replacement Model (ZW1500-X)	Key Advantages of ZW1500-X
Membrane Material	Standard PVDF hollow fiber membrane, providing reliable mechanical strength and chemical resistance.	Upgraded composite PVDF hollow fiber membrane, with tensile strength increased to 1.8 times that of the ZW1500. It features enhanced hydrophilicity and fouling resistance, ensuring stable flux retention (over 92% within a 3-year operation cycle).	Stronger mechanical performance, better anti-fouling ability, and longer stable operation cycle, reducing maintenance frequency.
Membrane Fiber Dimensions	Nominal fiber diameter: OD 1.2 mm, ID 0.66 mm.	Optimized nominal fiber diameter: OD 1.1 mm, ID 0.66 mm. The refined design improves flow distribution and reduces energy consumption during operation.	More uniform flow distribution, lower energy consumption, and improved operational efficiency.
Weight Specifications	Max shipping weight (packaged): 37 kg (80 lb); Lifting weight: 30-46 kg (65-100 lb) (varies with solids accumulation).	Max shipping weight (packaged): 32 kg (70 lb); Lifting weight: 30-36 kg (65-80 lb) (varies with solids accumulation).	Lighter design, simplifying transportation, handling and on-site installation, reducing labor costs.
Operational Energy Efficiency	Operates with stable transmembrane pressure (TMP) range of 0-276 kPa (0-40 psi), with standard energy consumption for operation.	Optimized flow channel design (via computational fluid dynamics simulation) controls TMP within 0.3 bar, significantly reducing system energy consumption. Equipped with "pulse air-water backwash" technology, reducing backwash water consumption by 45% compared to the ZW1500.	Lower energy and water consumption, reducing long-term operational costs and promoting environmental sustainability.
Intelligent Compatibility	Compatible with basic monitoring systems, requiring manual adjustment for cleaning cycles and operation parameters.	Fully compatible with Veolia’s patented AquaVision 3.0 monitoring system. This AI-enabled platform with machine learning algorithms can real-time predict membrane fouling trends and provide accurate chemical cleaning cycle recommendations, extending membrane service life by approximately 30%.	Intelligent operation and monitoring, reducing manual intervention, extending membrane service life, and improving system stability.
Application Adaptability	Suitable for conventional water quality conditions, including general drinking water treatment, tertiary filtration, and standard RO pretreatment. It has high solids tolerance and can handle moderate turbidity spikes.	Ideal for complex and harsh water quality conditions (e.g., high-turbidity raw water, drought-prone areas). It excels in municipal sewage reuse, high-demand RO pretreatment, and scenarios requiring long-term stable operation with minimal maintenance.	Wider adaptability to complex water quality, expanding application scenarios and ensuring stable performance in harsh environments.

4. Compatibility & Transition Guidelines

To ensure a seamless transition from the discontinued ZW1500 to the replacement ZW1500-X, Veolia has optimized the ZW1500-X to maintain full compatibility with the ZW1500 in terms of installation dimensions, connection standards and operational parameters. The key compatibility points and transition guidelines are as follows:

•          Installation Compatibility: The ZW1500-X maintains the same module dimensions and connection standards as the ZW1500 – Height 1919 mm (75.6 in), Diameter 180 mm (7”), Feed & Permeate 2” (DN 50) Victaulic, Reject 1½” (DN 40) Victaulic. It can be directly installed on existing ZW1500 module racks without any modifications to the system structure, ensuring quick and easy replacement.

•          Operational Compatibility: The ZW1500-X shares the same operating parameter ranges as the ZW1500, including flow range (45-180 m³/day / 8-33 gpm), max shell inlet pressure (379 kPa / 55 psi), max temperature (40 °C / 104 °F), operating pH (5.0-10.0), and cleaning specifications. Existing control systems can be directly used without parameter adjustments.

•          Transition Recommendations: For customers using the ZW1500, we recommend planning replacement with ZW1500-X during routine maintenance or system upgrades to minimize operational disruption. Veolia's technical support team is available to provide on-site guidance, installation assistance and training to ensure a smooth transition.

5. After-Sales Support & Contact Information
