To ensure optimal performance and long-term reliability of a decanter centrifuge, operators must adhere to specific principles and operational guidelines. Neglecting these procedures or deviating from the recommended sequence can lead to inefficiencies, increased maintenance time, and costly operational setbacks—especially when dealing with high-viscosity or high-solid-content liquids.
Proper understanding of the sludge characteristics, particularly the solid content and viscosity, is essential for effective separation and cleaning. Failure to follow operational protocols can result in irreversible damage, reduced efficiency, and increased treatment costs—ultimately turning minor mistakes into major losses.
Key Principles to Follow When Using a Decanter centrifuges:
Segregate Hazardous Wastewater:
Wastewater containing toxic substances—such as heavy metals, radioactive materials, or high concentrations of phenol and cyanide—should be treated separately. This allows for more targeted treatment and recovery of valuable or hazardous materials.
Ensure Proper Equipment and Workflow:
In processes involving toxic raw materials or intermediates, it is crucial to use appropriate process flows and reliable equipment. When operating a decanter centrifuge under such conditions, strict adherence to operating procedures and supervision is necessary to ensure safety and compliance.
Minimize Toxic Waste at the Source:
The most effective strategy for wastewater treatment is source control. This includes redesigning production processes to reduce or eliminate toxic effluents. Where possible, replace hazardous materials with non-toxic or less harmful alternatives.
