Metalworking
In the metalworking industry, water is a core auxiliary medium. During machining, it helps dissipate heat and protects both the cutting tool and the workpiece.
It can also serve as a carrier for water-based cutting fluids and other applications, reducing frictional losses.
It can simultaneously remove oil stains, debris, and other contaminants from the surface of workpieces, assist in surface treatments such as electroplating, and is also used for workshop cleaning and preliminary wastewater treatment, thereby ensuring the smooth operation of the entire manufacturing process.
The key to wastewater treatment
The pollution factors in wastewater from the metalworking industry are primarily concentrated on:
• Oil-based substances, including lubricating oils, heat-transfer oils, cutting fluids, and the like;
• Ionic substances, including fluoride ions, nitrate ions, acids and bases, metal ions, and more;
• TSS substances, including fine impurities generated during various cleaning processes and workshop cleaning operations.
The presence of the above-mentioned pollutants can also lead to an increase in COD; therefore, while removing these pollutants, it is also necessary to simultaneously consider reducing the COD level.
Huatai Environmental’s Solutions
Huatai Environmental Protection offers a variety of solutions tailored to different types of pollutants. HTBNR technology It can be applied to the treatment of solutions containing high concentrations of nitrate ions.
HTIPS technology CFS (Continuous Flow Sand Filtration) technology can be applied to remove various types of ionic pollutants and TSS pollutants.
Electrocatalytic oxidation technology It can significantly reduce the COD of oil-based pollutants and also help separate oil-based substances from water.
Huatai Environmental Protection offers comprehensive solutions that integrate biotechnology, advanced oxidation technologies, and solid-liquid separation technologies.
Numerous EPC projects have been constructed for wastewater treatment in the metalworking industry.
