In the hot-dip galvanizing process, effluents are generated at various stages, including alkaline degreasing, acid pickling, and fluxing. These effluents consist of continuously flowing water rinses, static water washes, and occasionally disposed solutions, such as degreasing agents and pickling acids. Effective treatment of these waste streams is essential to comply with environmental regulations, protect equipment, and maintain a safe, efficient workplace.
At Gunatit Engineers, we specialize in designing and supplying high-quality Effluent Treatment Plants (ETPs) tailored to the specific needs of galvanizing plants. With our extensive infrastructure and expertise, we provide ETP solutions that ensure effective treatment of all waste streams, enabling clean discharge and promoting environmental sustainability.
Our Effluent Treatment Plants are customized to meet the unique requirements of each galvanizing facility. We consider critical factors such as flow rate and the physical, chemical, and biological properties of the effluent to design a system that offers optimal treatment efficiency. This approach ensures that all contaminants, including waste acids and rinse water, are effectively treated and neutralized before discharge.
Initial removal of large particles and suspended solids to protect downstream components of the ETP.
pH adjustment to neutralize acidic or alkaline waste, ensuring safe and compliant discharge.
Addition of coagulants and flocculants to aggregate fine particles and other contaminants, facilitating easier removal.
Optional biological treatment to handle biodegradable waste, ensuring thorough cleanup of organic compounds.
Further purification through filtration and sedimentation to remove remaining impurities.
Clean, treated water is safely discharged or recycled for other uses, minimizing water consumption and environmental impact.
