Dear investor, hello. The Company has successfully extracted sodium carbonate, sodium sulfate, and sodium chloride from industrial high-salinity wastewater. Currently, the technology has not been applied to the pretreatment of sodium-ion battery materials. Thank you for your attention.

Dear investor, hello. The Company does not have applications in the related field. Thank you for your attention.

Dear investor, hello. The Company's core business focuses on sewage resource recycling and advanced industrial water treatment. The technology has not been applied to the pretreatment of sodium-ion battery materials. Thank you for your attention.

Dear investor, hello. The Company's core business focuses on sewage resource recycling, with a notable project achieving the first salt resource reuse system for high-salinity wastewater in China. The Company's municipal-industrial linkage project recycles municipal water for industrial use after treatment, achieving the circular utilization of water resources. With 17 years of focus on the water treatment industry, as a leading technical enterprise in the field of sewage resource utilization, the Company possesses a range of highly specialized core technologies, being capable of providing customized solutions for complex industrial wastewater issues across various sectors. As sewage resource utilization reform accelerates nationwide and national sewage treatment policies are consistently implemented, new opportunities for industrial development will emerge for the Company.

Dear investor, hello. The Company's technology has not been applied to the new generation sodium batteries at present. Thank you for your attention.

Dear investor, hello. 1. Moving forward, the Company will monitor market dynamics and continuously focus on market development opportunities according to market demand. 2. The independently developed GTR series medium-pressure membrane device (GTR3) and high-pressure membrane device (GTR4) are mainly used for removing soluble ions in water, with a removal rate of up to 98% and a water reuse rate of over 90%.

Dear investor, hello. The Company collaborated with Sanmenxia Lianli New Materials Co., Ltd. in 2018 for the research and development part of the "pilot test project for lithium-containing wastewater". After a successful experiment, the project was canceled due to other reasons.

Dear investor, hello. As a leader in the sewage resource recycling industry, the Company is well-positioned to capitalize on the accelerated national sewage resource recycling reform and the ongoing implementation of national sewage treatment policies, which will bring new opportunities for the Company's industrial development.

The Company's zero-discharge salt separation technology for high-salinity water is composed of unit operations in physics, chemistry, membrane separation, and evaporation, etc. These unit operations can be customized and combined to be used in lithium extraction projects. Currently, the Company does not have any existing orders for salt lake lithium extraction. Investors are advised to make rational investment decisions and be aware of investment risks.

Dear investor, hello. The Company's technology can provide customized comprehensive wastewater treatment solutions based on different industries (including medical wastewater) and water qualities.

Dear investor, hello. The Company has no other collaborations with Sanmenxia Lianli New Materials Co., Ltd.

Dear investor, hello. Based on the cooperation agreement, the Company jointly owns the results of the pilot test with Lianli New Materials. The Company will further verify and take corresponding measures regarding this matter. Thank you for your suggestion and attention.
