This eco-conscious company has successfully established strategic collaborations with esteemed automotive giants such as Mercedes-Benz China, marking the inception of a robust power battery recycling industry chain.
At the heart of Brunp Recycling’s remarkable success is its commitment to sustainable practices and the impressive metal recovery rates it has achieved. The company boasts a staggering 99.3% recovery rate for valuable metals like nickel, cobalt, and manganese from used batteries. This exceptional achievement not only ensures the conservation of critical resources but also significantly contributes to reducing the environmental impact of battery production.
CATL, in tandem with Brunp Recycling, has played a pivotal role in promoting environmental sustainability. Their collective efforts have culminated in an astonishing 50% comprehensive recycling rate for used batteries within China. Brunp Recycling, in particular, stands out with its remarkable waste battery disposal capacity, which currently exceeds 120,000 tons.
3 Major Features of Battery Recycling Wastewater
Battery recycling wastewater typically contains a variety of contaminants, including heavy metals, organic compounds, and acidic substances. These pollutants can be highly toxic and environmentally damaging if not properly treated.
- Heavy Metals: Battery recycling wastewater often contains heavy metals such as lead, cadmium, nickel, and cobalt, which are harmful to the environment and human health.
- Organic Compounds: Organic compounds like organic acids, solvents, and plasticizers may be present in battery recycling wastewater, posing a risk to aquatic ecosystems.
- Acidic pH: The wastewater can have an acidic pH due to the presence of sulfuric acid from battery electrolytes, which requires neutralization.
6 Role of Boron-Doped Diamond/BDD Electrode In Battery Recycling Wastewater Treatment
Boron-doped diamond/BDD electrode offer a unique and effective solution for addressing the challenges associated with battery recycling wastewater treatment. Boron-doped diamond electrodes are known for their exceptional electrochemical properties, making them well-suited for the treatment of complex industrial wastewater like those from battery recycling. Here’s how BDD electrodes can be used effectively:
Electrochemical Oxidation: BDD electrodes can oxidize organic compounds present in the wastewater through advanced oxidation processes (AOPs). The high overpotential of BDD allows it to generate hydroxyl radicals (•OH) at its surface, which are highly reactive and can efficiently break down organic pollutants into less harmful byproducts.
Heavy Metal Removal: BDD electrodes can electrochemically remove heavy metals through processes like electrocoagulation and electroflotation. Metal ions are attracted to the BDD electrode surface and can be precipitated or adsorbed, leading to their removal from the wastewater.
PH Adjustment: BDD electrodes can be used for pH adjustment by electrolyzing water to generate hydroxide ions (OH-) or protons (H+), depending on the needs of the wastewater treatment process. This is crucial for neutralizing acidic wastewater.
Longevity: BDD electrodes are highly durable and can withstand harsh conditions, making them ideal for continuous and long-term operation in the battery recycling industry.
Minimal Maintenance: BDD electrodes require minimal maintenance, reducing operational costs and downtime.
Environmental Benefits: BDD electrode-based treatment processes produce fewer secondary pollutants compared to traditional chemical treatments, contributing to a more sustainable and eco-friendly approach to wastewater treatment.
One groundbreaking development in the battery recycling industry is the application of boron-doped diamond electrodes. These advanced electrodes have gained significant traction due to their remarkable properties, making them a game-changer in the realm of wastewater treatment related to battery recycling.
Boron-doped diamond electrodes are renowned for their exceptional durability, high corrosion resistance, and impressive electrical conductivity. These attributes make them ideal for efficiently removing contaminants and impurities from wastewater generated during battery recycling processes. This innovative technology not only enhances the efficiency of metal recovery but also ensures that the wastewater discharged from recycling plants meets stringent environmental standards.
Furthermore, the use of bdd electrode aligns seamlessly with Brunp Recycling’s and CATL’s commitment to environmental responsibility. By incorporating this cutting-edge technology into their recycling operations, they are not only contributing to the circular economy by recovering valuable metals but also mitigating the environmental impact associated with wastewater disposal.
Brunp Recycling’s commitment to sustainability is further exemplified by their adoption of innovative BDD electrode wastewater treatment technology, which play a pivotal role in wastewater treatment and environmental conservation within the battery recycling sector.
