Sludge Storage

APRO Industrie designs and supplies bespoke sludge storage solutions for sludge from domestic and industrial wastewater treatment. Designed for a wide range of applications, our tanks are available with capacities ranging from 5 m³ to 10,000 m³, ensuring long-term durability and operational efficiency.

Our solutions are suitable for all types of sludge, with varying dry solids (DS) content, whether treated (e.g. by lime stabilisation) or untreated.

Due to the high fermentation potential of sewage sludge, the presence of hydrogen sulphide is often significant in sludge tanks. Protective coatings are selected to withstand these aggressive conditions and typically include:

Glass-fused-to-steel with mastic seals
Epoxy-coated steel with mastic or elastomeric seals

Our sludge tanks can be equipped with all standard accessories for this type of installation: agitators, pumps, guide bars, strainers, covers, odour control 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 sludge quality during storage and facilitate handling, storage and subsequent treatment for resource recovery.

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 provide efficient sludge storage across various industrial environments.

Technical Features of Our Solutions

Our sludge storage tanks are available in capacities 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 provide reliable sludge storage and have a service life of up to 50 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 operating correctly. It is recommended that inspections are carried out every two to three years.

What are the optimal conditions for storing sludge?

Tanks should be installed in a stable, level foundation with adequate ventilation and gas venting systems. It is also essential to ensure complete watertightness and, when necessary, provide odour control equipment.
