In today’s eco-conscious world, any indication of environmental negligence erodes public trust and taints the public opinion of reputable companies. The iron, steel and metalworks industry produces millions of metric tons of wastewater that if left unchecked, increases the risk of environmental pollution and reputational damage in the public eye. Efficient wastewater treatment for iron and steel production is crucial now more than ever.
The Importance of Wastewater Treatment for Iron and Steel Companies
Insufficiently treated wastewater pollutes waterways and threatens public health. According to section 34(7) of the EPA 1990, failure to comply with the code and duty of care set down in the environmental guidelines for industrial wastewater treatment is an offence. The UK’s IPPC Guidance for Coke, Iron, and Steel Production also sets out the standards and discharge limits for metalworking factories.
Authorities issue factories with discharge licenses, specifying their discharge limits. They conduct regular inspections to ensure all license holders meet their discharge limits. Non-compliance can attract hefty fines, closure of the factory, or jail time. Under the code of practice, factory owners and managers are “waste holders” and have a duty of care. Efficient wastewater treatment systems for your iron and steel works factory can help you avoid legal challenges.
Wastewater Treatment Systems for Metalworking
Iron and steel production combines carbon, nickel, cobalt, vanadium, molybdenum, chromium, manganese, tungsten, and other elements. It involves several processes, which rely on water for cooling, descaling, dust scrubbing, and more. They produce wastes like slags, sulfur, oils, greases, metal ions, ashes, ore particles, and flue dust, which enter the water as contaminants.
Wastewater from iron and steel production contain toxic compounds, suspended solids (SS), and oil and grease (O&G). These contaminants can increase biochemical oxygen demand (BOD) and chemical oxygen demand (COD). Wastewater with high BOD and COD requires specific treatment before it can be safely discharged. Treating industrial effluent on-site before discharging it requires a process driven solution. Wastewater treatment systems for iron and steel works should combine physical, chemical, and biological processes to remove SS and O&G and reduce BOD and COD.
Wastewater Treatment Solutions for Iron and Steel Production
Efficient wastewater treatment solutions for iron and steel production should use containerized plants and DAF systems.
Containerized wastewater treatment for Metalworking
Containerized wastewater treatment plants are ready-to-use systems. They come in different sizes and functionalities. There are mobile containers for bio-driven treatment for small processing plants that only need this functionality. However, end-to-end iron and steel production needs four-in-one containerized systems with primary treatment, clarification, biological treatment, and tertiary treatment. First, remove SS and O&G in wastewater for iron and steel production. Second, use biological treatment to remove biodegradable components. Combining all four approaches can help you treat highly contaminated wastewater from your iron and steel factory to meet discharge limits.
The benefits of using containerized plants go beyond wastewater treatment, for example, the five business values of Biocell containerized wastewater treatment solutions:
- Cost-effective. Buying a four-in-one containerized solution will cost less than getting four treatment systems independently.
- Easy to use. You don’t need technical expertise to use your containerized wastewater treatment plant. You plug and play.
- Mobility. Containers are highly mobile. If your factory spans several acres, you can move your containerized wastewater treatment plant along the production line. You can also move it between your factories to meet your needs.
- Quick launch. Your wastewater treatment service provider can deliver your system and set it up in a few hours. You can start using the solution in less than 12 hours.
- Low upfront investment. Containerized systems do not require additional infrastructure. It only needs a solid concrete or stone foundation.
To enjoy all these benefits, get Biocell containerized wastewater treatment solution. Biocell can customize the treatment plant to meet your factory’s unique needs.
DAF for iron and steel production
Dissolved air flotation (DAF) uses the clarification process to separate solids, grease, and oils in wastewater. These capabilities make it a must-have wastewater treatment solution for iron and steel factories. DAF systems produce a stream of micron-sized bubbles that attach to suspended slag, metal ions, oils, greases, ashes, ore particles, and flue dust from iron and steel production.
The bubbles rise to the surface, along with attached SS, O&G, and other contaminants. Most DAF systems use mechanical skimmers and scrappers for floatation sludge. The Biocell DAF Wastewater Container Plant operates fully automatically. This robust DAF plant is versatile, energy-efficient, and upgradable with additional modules. It comes with all treatment technologies preinstalled, allowing for quick setup, installation, and launch. With the Biocell DAF system, you can reduce SS, O&G, BOD, and COD in your wastewater and meet discharge limits.
Whether you’re a factory manager or owner, you need efficient wastewater treatment for iron and steel production to avoid non-compliance and legal issues. Containerized plants and DAF systems can help reduce suspended solids, oils, greases, and other contaminants. Combining four-in-one containerized systems with DAF delivers highly efficient wastewater treatment for the iron and steel works industry. To avoid performance issues, get your treatment system from a reliable provider like Biocell Water.
