On June 3, 2026, the SNEC PV&ES Expo opened at the National Exhibition and Convention Center in Shanghai, with multiple Chinese suppliers presenting MVR evaporators designed for high-salinity wastewater in photovoltaic silicon materials and lithium battery materials. The development deserves attention from photovoltaic manufacturing, battery materials, chemical park development, wastewater treatment equipment, and supply chain service companies because it points to a more integrated approach to zero liquid discharge in industrial wastewater scenarios.
Event Overview
The 19th SNEC PV&ES Expo opened in Shanghai on June 3, 2026. On the first day of the exhibition, several Chinese suppliers displayed MVR evaporators customized for high-salinity wastewater applications, including photovoltaic silicon materials and lithium battery materials.
According to the public event information, exhibitors highlighted a thermal-membrane coupling system that combines RO concentration with MVR evaporation. The stated positioning is to support a full-chain domestic delivery model for ZLD, or zero liquid discharge, while reducing energy consumption by 35% compared with traditional solutions.
Informa confirmed that overseas inquiries for this category of equipment increased by 210% year on year, with demand mainly coming from newly built chemical parks in Mexico, Vietnam, and Saudi Arabia.
Which Segments May Be Affected
Photovoltaic Silicon Material Producers
Photovoltaic silicon material producers are directly relevant to this development because the displayed MVR evaporators were specifically positioned for high-salinity wastewater scenarios in photovoltaic silicon materials. The impact may be reflected in wastewater treatment route evaluation, ZLD system configuration, and energy consumption comparison when planning new production capacity or upgrading existing facilities.
From an industry perspective, the key point is not only whether MVR evaporation can be applied, but whether the RO concentration and MVR evaporation combination can fit the wastewater characteristics and compliance requirements of each production site.
Lithium Battery Material Manufacturers
Lithium battery material companies may also be affected because the event information specifically mentions lithium battery materials as a target application scenario. For manufacturers handling high-salinity wastewater, the exhibition signals that equipment suppliers are increasingly packaging evaporation and membrane concentration as one integrated ZLD route.
Analysis shows that these companies may need to compare thermal-membrane coupled systems with existing treatment processes in terms of energy use, system stability, and delivery capability, rather than evaluating evaporation equipment as a standalone unit.
Industrial Wastewater Treatment Equipment Suppliers
Equipment suppliers in evaporation, membrane treatment, and ZLD systems may face stronger demand for integrated solutions. The highlighted system combines RO concentration and MVR evaporation, which means customers may pay closer attention to process coordination, energy performance, and full-chain delivery capability.
What deserves closer attention now is whether suppliers can provide credible project-based technical documentation for high-salinity wastewater conditions, especially when overseas inquiries are increasing from chemical park projects.
Overseas Chemical Park Developers and Procurement Teams
The confirmed increase in overseas inquiries is mainly from newly built chemical parks in Mexico, Vietnam, and Saudi Arabia. These markets may be affected at the procurement and project-planning levels, especially where industrial wastewater treatment must be considered early in infrastructure design.
Observably, the inquiry growth indicates rising interest, but it should not be interpreted as completed adoption. Procurement teams still need to assess site-specific wastewater composition, energy availability, operation requirements, and supplier delivery capacity before making technical decisions.
Supply Chain and Engineering Service Providers
Supply chain service providers, engineering firms, and project integrators may be affected because full-chain delivery for ZLD requires coordination across membrane systems, evaporation units, auxiliary equipment, installation, and commissioning. If overseas demand continues to rise, these companies may need to prepare for more cross-border technical communication and project execution requirements.
From an industry perspective, the practical impact is likely to appear in specification alignment, equipment selection, delivery schedules, and after-sales service planning for new chemical park projects.
What Companies and Practitioners Should Watch and How to Respond
Track Further Official Statements and Verified Project Updates
Companies should continue to monitor official information from SNEC PV&ES Expo, Informa, and participating suppliers. The current information confirms exhibition displays, a stated 35% energy consumption reduction versus traditional solutions, and a 210% year-on-year increase in overseas inquiries. However, further details on project execution, confirmed orders, and operating data still require continued observation.
Focus on Key Applications and Markets Mentioned in the Event
Practitioners should prioritize the applications explicitly mentioned in the event information: photovoltaic silicon materials, lithium battery materials, and high-salinity wastewater. On the market side, Mexico, Vietnam, and Saudi Arabia deserve close attention because Informa identified new chemical parks in these countries as the main sources of overseas inquiries.
Analysis shows that companies involved in these areas should prepare technical materials around wastewater concentration, salt load, energy consumption, ZLD configuration, and delivery scope to support more efficient project discussions.
Distinguish Market Inquiries from Business Implementation
The 210% increase in overseas inquiries is an important market signal, but it should not be treated as equivalent to confirmed project deployment. It is more appropriate to understand this as a sign of rising attention toward thermal-membrane coupled MVR evaporators in overseas industrial wastewater treatment projects.
Companies should separate inquiry tracking, technical evaluation, commercial negotiation, and final project delivery in their internal assessment. This can help avoid overestimating short-term demand while still preparing for potential procurement activity.
Prepare Practical Evaluation and Communication Materials
For manufacturers, engineering firms, and procurement teams, the immediate response should be practical: collect wastewater data, define ZLD targets, compare RO concentration plus MVR evaporation with current treatment routes, and clarify supplier responsibilities across the full chain.
What deserves closer attention now is the compatibility between process design and actual wastewater conditions. Before adopting any system, companies should confirm whether the proposed thermal-membrane coupling route matches their operating environment, energy assumptions, and project delivery timeline.
Editor’s View / Industry Observation
From an industry perspective, the SNEC PV&ES Expo development reflects a stronger link between new energy manufacturing and industrial wastewater ZLD technology. The attention around MVR evaporators is closely tied to high-salinity wastewater in photovoltaic silicon materials and lithium battery materials, rather than a general equipment trend detached from specific applications.
Analysis shows that the event is better understood as a market signal than as a final industry conclusion. The exhibition displays and inquiry growth indicate that thermal-membrane coupling is gaining attention, especially in overseas chemical park projects. Whether it becomes a widely adopted configuration will depend on verified project performance, site-specific applicability, and supplier execution capability.
Observably, the most important takeaway for industry participants is the shift from single-equipment procurement to integrated ZLD system evaluation. Companies need to assess membrane concentration, evaporation, energy consumption, delivery capability, and overseas project support as one connected decision.
Conclusion
The opening of the 19th SNEC PV&ES Expo has brought thermal-membrane coupled MVR evaporators into sharper focus for high-salinity wastewater treatment in photovoltaic silicon materials, lithium battery materials, and new chemical park projects. The confirmed rise in overseas inquiries shows increasing market attention, particularly from Mexico, Vietnam, and Saudi Arabia.
It is more appropriate to understand this development as an important industry signal rather than a completed market outcome. Companies should respond by tracking verified updates, evaluating application-specific wastewater conditions, and preparing practical technical and procurement plans based on their own project needs.
