Jiuwu Hi-Tech Showcases Zero-Liquid Discharge Integrated Solutions on 10th Guangdong Water Expo

Four-Dimensional In-Depth Analysis: Deconstructing the Core Logic of Industrial Wastewater Zero Liquid Discharge

Dr. Zhang Chun delivered an in-depth interpretation, focusing on four key dimensions: the significance and necessity of industrial wastewater zero liquid discharge, design approaches for industrial wastewater zero liquid discharge and waste salt utilization, core innovative technology pathways, and sharing of typical engineering cases. He pointed out that in recent years, national ministries and commissions have intensively issued relevant policies on wastewater resource utilization and zero liquid discharge, encouraging qualified regions to carry out demonstration projects. However, traditional zero liquid discharge processes still face significant pain points:

1. High project investment and operating costs, placing prominent cost pressure on enterprises;

2. The system generates large amounts of difficult-to-dispose waste salt, with high third-party treatment costs that can easily lead to secondary pollution and environmental risks—becoming a key bottleneck restricting green industrial development.

Currently, most enterprises and industrial parks adopt the mainstream "pretreatment + membrane concentration + evaporation" route for wastewater zero liquid discharge. Although this approach achieves full water reuse and zero liquid discharge, it has shortcomings in cost control and waste salt reduction. Addressing common industry challenges, Jiuwu Hi-Tech leverages its proprietary membrane technology advantages to propose two innovative breakthrough strategies:

1. Adoption of Advanced Low-Cost Membrane Integration Technology

Significantly reduces evaporation water volume, lowering system construction investment and operational energy consumption from the source — solving the "high investment, high consumption" dilemma of traditional processes.

2. Salt Ion Modulation + Nanofiltration Salt Separation Technology

Precisely separates sodium chloride and sodium sulfate in high-concentration brine, enabling resource recovery and high-value utilization of both salts. This approach reduces waste salt generation by over 95%, truly achieving "waste-to-resource and waste-treats-waste."

Proven Results Across Multiple Industries: Full-Process Solutions Delivering Tangible Outcomes

During his speech, Dr. Zhang Chun elaborated on the application achievements of Jiuwu Hi-Tech's full-process solution—"Advanced Pretreatment + Membrane Integration Concentration + Efficient Evaporation Crystallization" — through practical cases across multiple industries, including fine chemicals, salt chemicals, and pulp and paper.

This solution has been validated through implementation in various sectors such as papermaking, printing and dyeing, chemicals, metallurgy, and new energy. It not only consistently achieves zero liquid discharge and wastewater resource recycling but also generates additional economic benefits through waste salt resource utilization. By simultaneously delivering both environmental and economic gains, it provides a replicable and scalable practical model for the green and low-carbon transformation of industrial enterprises.

As a leading enterprise in China's membrane separation technology and water treatment resource recovery sectors, Jiuwu Hi-Tech has always taken technological innovation as its core driving force. The company is deeply engaged in fields such as industrial wastewater treatment, waste salt resource utilization, and lithium extraction from salt lakes. Leveraging innovation platforms including the National and Local Joint Engineering Research Center for Inorganic Membranes and the National Postdoctoral Research Station, Jiuwu continuously achieves breakthroughs in key core technologies, breaking foreign technological monopolies.

Its presence at the Guangdong Water Expo serves both as a comprehensive showcase of the company's technical strength and engineering experience, and as a demonstration of Jiuwu Hi-Tech's commitment and responsibility in supporting industrial water conservation and pollution reduction, as well as advancing the realization of the national "Dual Carbon" goals.

Looking ahead, Jiuwu Hi-Tech will continue to focus on addressing pain points in the industrial water treatment and resource recovery sectors, continuously iterating and upgrading its technological solutions, and deepening cooperation and exchanges with upstream and downstream partners. By providing more advanced, more economical, and more environmentally friendly comprehensive treatment technologies, Jiuwu aims to inject strong momentum into the green and high-quality development of industrial enterprises and parks nationwide.
