Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, and more specifically to a sludge dehydration filter press device. Background Art

[0002] A large amount of sludge will be generated during the sewage treatment process. It has a large volume and high water content. In order to separate the water from the sludge, a filter press is usually used to separate the sewage.
