Sludge Dewatering at Municipal Sewage Purification Facilities using Geotubes®

In recent years, numerous sewage treatment and recycling plants have been constructed, employing various technologies. As part of the treatment process, sludge with a relatively low concentration of solids is generated, which requires drying/ dewatering in order for the treatment or removal to continue. Sludge dewatering allows for the removal of solids for a wide range of end-user solutions, from using it as fertilizer to removing it to landfills if needed.

Admir Environment offers ecological solutions for dewatering of sludge from the design phase through the implementation phase, including the construction of apparatuses at municipal sewage purification facilities.

Sludge Dewatering by Means of Geotubes®

Geotechnical sleeves made of polypropylene sheets with fast and efficient filtration capabilities, high resistance to chemical corrosiveness, and proven economic advantages.

The Dewatering is Performed in Three Phases:

• Sludge dewatering and polymer blending to create flocculation.
• Separation of clean water from solids (ability to remove over 99% of solids). The solids remain trapped in the receptacles.
• Leaving the solids for an additional time period so they may dry, consolidate, and decrease in volume.

Geotube Dewatering is Especially Efficient for the Following Applications at Sewage Purification Facilities

• Sludge dewatering in sedimentation reservoirs as well as processed sludge that contains a high percentage of mineral sludge.
• Execution of sludge dewatering projects that demand the dewatering of large volumes of sludge quickly; using the Geotube method, very high output dewatering is possible.
• Using Geotubes allows for the rapid rehabilitation and cleaning of reservoirs, reactors, etc.
• The Geotube can serve as an emergency solution for other dewatering systems.
• Integration of Geotubes is efficient at small sewage treatment facilities, where the price of alternative dewatering equipment can be costly.
