150T/D Thallium-Bearing & 2400T/D Wastewater Treatment Project for Ganfeng Lithium

WTEYA successfully delivered a comprehensive wastewater treatment solution for Jiangxi Ganfeng Lithium Co., Ltd., one of the world's leading lithium producers. The project encompasses two integrated systems: a 150 T/D thallium-bearing wastewater treatment system and a 2,400 T/D general industrial wastewater treatment facility, ensuring compliant discharge and water reuse.

🤝 Project Overview

Client: Jiangxi Ganfeng Lithium Co., Ltd. (a global top-tier lithium producer)

Project Scale:

• System 1: 150 T/D thallium-bearing wastewater treatment
• System 2: 2,400 T/D general industrial wastewater treatment

Location: Jiangxi Province, China

Ganfeng Lithium is a core client in WTEYA's portfolio of 40+ listed enterprise partners. As a leading player in the new energy materials industry, Ganfeng requires stringent wastewater treatment to meet both environmental compliance and resource recovery objectives. This project demonstrates WTEYA's capability in handling complex heavy metal wastewater, particularly thallium — one of the most challenging contaminants in lithium extraction and processing.

💧 The Challenge: Thallium in Lithium Industry Wastewater

Thallium (Tl) is a highly toxic heavy metal that occurs naturally in lithium-bearing ores. During lithium extraction and processing, thallium enters the wastewater stream at concentrations far exceeding discharge standards. Key challenges include:

• Extreme toxicity: Thallium is more toxic than mercury, lead, or cadmium, with strict discharge limits (typically <0.1 μg/L in China)
• Complex speciation: Thallium exists in multiple oxidation states (Tl⁺ and Tl³⁺), requiring targeted oxidation strategies
• Low concentration, high volume: Even trace amounts in large wastewater volumes demand highly efficient removal technologies
• Co-occurring metals: Lithium wastewater often contains lithium, sodium, calcium, and other metals that complicate selective thallium removal
• Discharge compliance: Meeting China's stringent GB 31570 and local Jiangxi provincial standards for thallium discharge

⚡ Engineering Solution 1: 150 T/D Thallium-Bearing Wastewater Treatment

Treatment Target: Thallium-bearing wastewater compliant discharge and reuse

Process Flow:

Thallium-bearing wastewater → Integrated High-Efficiency Thallium Removal Equipment (Chain Reaction Catalytic Oxidation) → Chemical Precipitation → Compliant Reuse

Integrated High-Efficiency Thallium Removal Equipment

The core of this system is WTEYA's proprietary high-efficiency thallium removal device, which employs chain reaction catalytic oxidation technology to generate hydroxyl radicals (·OH). Hydroxyl radicals possess extremely strong oxidizing capability, with an oxidation potential of 2.80V — second only to fluorine. This makes the system particularly effective for:

• Biologically refractory wastewater that resists conventional chemical oxidation
• Heavy metal complex wastewater requiring advanced oxidation
• High-concentration thallium wastewater demanding >99% removal efficiency

Equipment Specifications:

• Capacity: 150 T/D
• Material: Carbon steel with three-layer fiberglass five-coat anti-corrosion / PPH material
• Integrated systems: Inlet water system, dedicated oxidation system, pH control system, automatic dosing system, and drainage system
• Automation: PLC-based control with real-time monitoring of pH, ORP, and flow rates

The chemical precipitation stage following oxidation uses specialized coagulants and flocculants to precipitate oxidized thallium compounds, achieving final effluent thallium concentrations well below regulatory limits. The treated water is recycled back into the production process, achieving zero liquid discharge for the thallium-bearing stream.

🏭 Engineering Solution 2: 2,400 T/D General Wastewater Treatment

Treatment Target: Compliant discharge to environmental standards

Process Flow:

Wastewater → pH Adjustment Tank → Physicochemical Reaction → Sedimentation Tank → Clear Water Tank → Compliant Discharge

Process Details:

• pH Adjustment: Automatic pH correction using acid/alkali dosing to create optimal conditions for subsequent coagulation and precipitation
• Physicochemical Reaction: Coagulation and flocculation with PAC (polyaluminum chloride) and PAM (polyacrylamide) to aggregate suspended solids, colloidal particles, and residual metal ions
• Sedimentation: High-efficiency lamella sedimentation tank with optimized surface loading rate to achieve rapid solid-liquid separation
• Clear Water Tank: Final polishing and flow equalization before compliant discharge
• Sludge Handling: Generated sludge is dewatered using a filter press, with dewatered cake disposed of in accordance with hazardous waste regulations

This 2,400 T/D system handles general process wastewater from lithium production, including lithium carbonate production, lithium hydroxide processing, and ancillary operations. The physicochemical treatment approach ensures reliable removal of suspended solids, heavy metals, and chemical oxygen demand (COD) to meet discharge standards.

🌍 Technical Highlights & Innovation

• Proprietary Thallium Removal Technology: WTEYA's chain reaction catalytic oxidation generates hydroxyl radicals (2.80V oxidation potential) for superior thallium removal efficiency exceeding 99%
• Dual-Stream Integration: Separate treatment of thallium-bearing (150 T/D) and general wastewater (2,400 T/D) streams, with optimized process selection for each
• Resource Recovery: Treated thallium-bearing wastewater is recycled for reuse, reducing fresh water consumption and supporting ZLD objectives
• Robust Material Selection: Carbon steel with three-layer fiberglass five-coat anti-corrosion and PPH materials ensure long-term durability in corrosive wastewater environments
• Full Automation: PLC control systems with pH/ORP/flow monitoring enable unattended operation and real-time process optimization
• Compliance Assurance: Effluent meets China's stringent GB 31570 standards and Jiangxi provincial thallium discharge limits
