Sludge Storage

APRO Industrie provides bespoke storage solutions for sludge from domestic and industrial wastewater treatment. Designed for diverse applications, our tanks offer capacities ranging from 5 m³ to 10,000 m³ and ensure both durability and efficiency.

Our solutions are suitable for all types of slurries, regardless of the dry content or whether a prior treatment (e.g., lime stabilization) has been applied.

Due to the high fermentation potential of sewage slurries, the presence of hydrogen sulfide is often significant in sludge tanks. Coatings are therefore adapted accordingly and typically include:

  • Glass-fused-to-steel with a mastic sealing
  • Epoxy-coated steel with a mastic or elastomeric sealing 

Our sludge tanks can be equipped with all standard accessories for this type of installation: agitators, pumps, guide bars, strainers, covers, odor treatment systems, and more.

Our Solutions for Sludge Storage

Glass-Fused-to-Steel Tanks for Organic Sludge

These tanks are designed for sludge from domestic or industrial wastewater treatment. They maintain the integrity of the sludge while facilitating its storage and treatment for future valorisation.

Glass-Fused-to-Steel Tanks for Mineral Sludge

Designed specifically for mineral sludge resulting from drilling, mining and grinding processes, these tanks offer enhanced resistance to harsh conditions. Thanks to their modular design, they can be installed flexibly and efficiently manage sludge across various industrial environments.

Technical Features of Our Solutions

Our sludge storage tanks are available in sizes ranging from 5 m³ to 10,000 m³ and can be customised with equipment such as agitators and odour treatment systems. Thanks to their robust construction, they ensure optimal sludge management and have a service life of up to 30 years.

FAQs - Sludge Storage


In this section, we answer the most common questions regarding our sludge storage tanks, providing the essential information to help you make the best choice based on your needs.

What is the maximum capacity of a sludge storage tank?

Our tanks are available in a range of capacities from 5 m³ to 10,000 m³, covering a wide variety of needs, from small-scale installations to large industrial projects.

How are sludge storage solutions maintained?

Sludge tank maintenance involves regularly inspecting equipment such as agitators and pumps, as well as checking the condition of the coatings and seals to ensure they are functioning properly. It is recommended that inspections are carried out every 2 to 3 years.

What are the optimal conditions for storing sludge?

Tanks should be installed in stable areas with adequate ventilation and gas evacuation systems. It is also essential to ensure complete watertightness and, when necessary, provide odor treatment equipment.
