Customer Profile:China * is a battery enterprise with a full industry chain. Building a vertically integrated industrial chain from mineral mining, material production, battery manufacturing, product application, to battery recycling and utilization is one of the few battery companies in the world with full industry chain manufacturing capabilities. In the previous article, we shared with you the sewage system we designed for the country. In this issue, we will share another set of pure water system we provided for it.
Project Name Enterprise:State * Power Energy Co., Ltd
Project Name: National Battery Pure Water Project
Project scale:6T/H battery production water
Run time:2023
Main process: Pre treatment+primary reverse osmosis+secondary reverse osmosis+EDI+polishing resin
Processing standards: Meet the water requirements for battery production, with a water outlet resistivity of 18M Ω· cm
Project features: Stable operation, installed with all stainless steel and PVC pipes, ensuring stable equipment operation and meeting the water quality requirements for battery production. The dual guarantee of EDI process and polishing resin process is adopted to ensure the standard of effluent water quality. Nitrogen protection is used to isolate the air and ensure the stability of effluent water quality.
In order to improve product quality and reduce production costs, China has decided to build a lithium battery ultrapure water preparation system, which is mainly used to prepare electronic grade ultrapure water and meet the high requirements for water quality in the battery production process.
Based on the specific needs of the owner (water usage situation) and the overall actual situation of the project, the overall treatment method of this system mainly includes pre-treatment, two-stage reverse osmosis, EDI purification system, etc. The water quality resistivity is ≥ 18 Ω· cm, and the EDI and polishing mixed bed 6T/H equipment produces no less than 4T/H of water in winter. Adopting EDI+ultra pure water polishing resin process, flexibly utilizing ion exchange technology, using high voltage at both ends of the electrode to move charged ions in water, and cooperating with ion exchange resin to accelerate ion movement and removal, achieving the purpose of water purification..
In this process, the quality of the effluent water after ion exchange mainly depends on the quality of the ion exchange resin and the exchange efficiency between water and resin in the exchange column.
The overall operation effect of the project is very stable, with a water resistivity of over 18M Ω· cm.
Our final process effect:
The water quality meets the standard After being processed by the pure water preparation system, all indicators of the pure water meet the requirements of lithium battery production. The resistivity reaches over 18M Ω· cm, the particle content is extremely low, and the microbial indicators have been effectively controlled.
Effectively reducing costs This project adopts advanced water treatment technology and equipment, which improves the utilization rate of water and reduces wastewater discharge. At the same time, by optimizing design and operational management, the energy consumption and chemical consumption of the system have been reduced, thereby lowering production costs.
The system runs stably and reliably High degree of automation and convenient operation and maintenance. Adopting advanced online monitoring and control systems to monitor water quality and equipment operation status in real-time, ensuring the safe and stable operation of the system.
The adoption of this new process for producing ultrapure water not only produces high-quality ultrapure water, but also achieves the goal of saving initial engineering investment, saving equipment footprint, and reducing operational electricity consumption. Not only that, but our clients also highly appreciate our work details and project site.
