Electrofiltration can be effective for “difficult to dewater” sludges. However, the electrodewatering is not yet commonly used in industry because of different side effects related to the electrical current application.

A new pilot filter-press has been developed by CHOQUENET in order to study the applicability of electro-technology on various industrial sludges.

The experiments with hydrocarbon sludge, fish farming sludge, and drilling sludge were realized. This study revealed several technical issues that have been solved for an industrial commercialization of sludge electrofiltration and electrodewatering.
