Processing and dewatering the sludge generated from wastewater treatment is a major challenge for municipalities and industrial plants. A filter press can be an effective solution for wastewater sludge dewatering applications.

Filter presses use mechanical pressure to squeeze water out of wastewater sludge between filter plates or on a filter belt. This results in a compact dewatered sludge cake that is easier to handle, transport and dispose.

In wastewater treatment plants, filter presses can dewater primary and secondary sludges from clarifiers. They help achieve higher solid contents in the sludge cake up to 30-35%. This significantly reduces sludge volume and disposal costs.

Tell You Types Of Filter Presses

The main types of filter presses used in wastewater treatment are frame filter presses and belt filter presses. Belt filter presses tend to have a higher throughput but require more maintenance. The choice depends on plant requirements.

Filter Presses Offer Several Benefits For Wastewater Sludge Dewatering:

  • High sludge solid contents up to 35% achievable
  • Continuously operate for non-stop dewatering
  • Compact footprint saves space
  • Flexibility to handle varying sludge characteristics
  • Minimal chemical conditioning generally required

Installing A Filter Press System In Your Wastewater Treatment Plant

By installing a filter press system in your wastewater treatment plant or industrial wastewater treatment facility, you can significantly improve the efficiency of sludge dewatering. A properly designed filter press can help reduce sludge disposal costs and optimize filter press in wastewater treatment processes.
