The solution fully complies with Vietnam's industrial water quality requirements and environmental regulations for the rapidly growing new energy battery industry.
Vietnam Tianneng Battery Industrial Pure Water Production Project
With the rapid expansion of Vietnam's new energy battery industry, Tianneng Battery's overseas manufacturing base requires a highly reliable source of industrial pure water to support large-scale battery production. Processes such as battery slurry preparation, electrode cleaning, electrolyte formulation, and equipment cooling demand consistently high-purity water to ensure product quality and manufacturing stability.
However, the local raw water source contains relatively high levels of dissolved salts, hardness minerals, and suspended impurities. If untreated water were used directly in production, residual ions and contaminants could result in incomplete electrode cleaning, reduced electrolyte purity, excessive ionic contamination within battery cells, shortened cycle life, and lower production yield.
To address these challenges, Baihuipu engineered a customized industrial pure water solution specifically designed for Vietnam's water quality characteristics, tropical climate, and overseas operating conditions with limited maintenance personnel.
Raw water first passes through a multi-stage pretreatment system, where suspended solids, organic contaminants, and residual chlorine are progressively removed. This pretreatment process significantly improves feed water quality while protecting downstream reverse osmosis membranes against fouling, scaling, and premature aging.
Following pretreatment, the water enters a two-pass reverse osmosis (RO) system, which efficiently removes dissolved salts, hardness ions, and other ionic contaminants. The result is high-quality industrial pure water with low conductivity and stable quality, fully meeting the stringent requirements of battery manufacturing processes.
The complete system operates automatically under a PLC-based intelligent control platform, eliminating the need for continuous manual supervision. The automation system continuously adjusts production capacity according to fluctuations in plant water demand while maintaining stable outlet pressure and minimizing operating costs and energy consumption.
Since commissioning, the system has consistently delivered stable water flow, uniform water quality, and excellent resistance to fluctuations in raw water conditions. It provides a reliable supply of industrial pure water for battery slurry preparation, electrode cleaning, electrolyte mixing, equipment cooling, and other critical production processes.
By eliminating production risks associated with poor raw water quality, the project has significantly improved battery product quality, increased manufacturing yield, and enhanced the overall stability of overseas production operations.
Today, this project serves as an excellent benchmark for industrial pure water systems supporting battery manufacturing across Southeast Asia, demonstrating Baihuipu's expertise in delivering reliable, energy-efficient, and fully automated water treatment solutions for the global battery industry.
