Key Purchasing Considerations for Used Wastewater Equipment

• Material Compatibility: Ensure the equipment's materials (e.g., stainless steel grade 316L, Hastelloy) are resistant to the specific chemicals and substances in your wastewater.
• Processing Capacity: Verify that the machine's throughput (e.g., m³/hour or GPM) matches your facility's processing requirements.
• Condition of Wear Parts: Inspect critical components like filter cloths, centrifuge bowls, or pump impellers for wear and tear, as their replacement can be costly.

Frequently Asked Questions About Wastewater Treatment Equipment

What is a decanter centrifuge used for?

A decanter centrifuge is a machine that uses high rotational speed to separate solids from liquids. In wastewater treatment, it's commonly used for dewatering sludge, thickening sludge, and clarifying effluent, resulting in a drier solid cake and a clearer liquid output.

How does a chamber filter press work?

A chamber filter press dewaters sludge by pumping it into a series of chambers formed by filter plates. High pressure is applied, forcing the liquid (filtrate) through filter cloths while the solids (filter cake) are retained in the chambers. Once the cycle is complete, the press opens, and the solid cakes are discharged.
