Electro-Filter Plates Sludge Dryer

The all-new sustainable electrodialysis technology for effective sludge dewatering

Overview

Sludge is a resource

Today, sewage sludge is increasingly being recognized as a resource.

Although the disposal of sludge by landfilling remains a common practice in many parts of the world, the method is fast phasing out as Governments tighten environmental regulations to reduce greenhouse gas emissions, prevent secondary contamination, and to free up valuable land for other uses.

Sludge contains a significant amount of water — as much as 80% — and the disposal of this wet sludge is a source of environmental concern. The treatment of sludge to reduce volume and to transform it into recoverable products has become a growing necessity. 

The effective treatment of sludge provides tangible following benefits:

  • sludge volumes and the associated disposal costs are significantly reduced 
  • water is recovered for potential reuse
  • health risks associated with sludge are reduced or eradicated
  • agricultural fertilizer can potentially be created

Anyway, most municipalities handling sewage sludge would have it dewatered and stabilized to ensure that regulatory requirements for treatment and disposal are met.
