Australia is actively developing its high-tech manufacturing industry. The introduction of the semiconductor industry poses extreme challenges to the local environmental protection. The wastewater produced during semiconductor production is complex in composition and highly toxic, containing fluoride, heavy metals, organic solvents, and grinding particles, etc. Improper treatment will cause serious harm to the environment. Baohupu Environmental Protection, as an expert specializing in the treatment of difficult industrial wastewater, with its advanced production plant located in China and rich international project experience, provides compliant, efficient, and reliable overall solutions for semiconductor production wastewater treatment and zero discharge for Australian semiconductor enterprises.
The core challenges in semiconductor wastewater treatment and the countermeasures of Baohupu
Deep treatment of fluorine-containing wastewater
Challenge: During the etching and cleaning processes, a large amount of fluorine-containing wastewater is produced, with high concentration of fluoride ions. Traditional processes are unable to consistently meet the standards.
Bai Huipu Solution: It adopts a combination of multi-level chemical precipitation and patented adsorption technology. Through precise pH control and calcium salt precipitation, along with efficient fluoride removal agents, it ensures that the fluoride ion concentration in the effluent remains stable and is lower than the strict local discharge standards in Australia (typically < 5mg/L).
2. CMP Grinding Wastewater Treatment and Resource Recovery
Challenge: The chemical mechanical polishing wastewater contains nano-sized silicon particles, metal oxides and chemicals, with high turbidity and great difficulty in treatment.
Bai Huipu Solution: Utilizing the core process of "coagulation sedimentation + ultrafiltration (UF)", it efficiently retains suspended particles and the produced water can be reused in the previous process. At the same time, we dehydrate and dry the concentrated sludge to achieve reduction and resource utilization of solid waste.
3. Treatment of Organic Wastewater and Heavy Metal Wastewater
Challenge: Processes such as lithography and etching produce wastewater with high concentrations of organic substances, while the metal wiring process generates wastewater containing heavy metals like copper and nickel.
Baihuipu Solution: For high COD organic wastewater, advanced oxidation technology is employed for complexation disruption and degradation. For heavy metal wastewater, processes such as ion exchange and special membrane separation are adopted to ensure efficient removal and recovery of heavy metal ions.
Baihuipu Zero Emission Solution: Meeting Australia's Strictest Environmental Standards
To meet the strict water resource protection and total discharge limits in some areas of Australia, BHP provides the ultimate zero-emission solution. The system integrates the aforementioned pre-treatment units, and ultimately achieves deep concentration and crystallization through reverse osmosis (RO) and mechanical vapor recompression evaporator (MVR), converting the dissolved solids in the wastewater into high-purity distilled water for reuse and drying of crystalline salts, thereby achieving nearly 100% wastewater recycling and classified disposal of solid waste.
