Depending on the aggressiveness of the effluent to be stored and processed, our tanks may be powder coated or provided with a specific vitrification coating.

The choice between these different solutions will depend on the aggressiveness of the effluents to be stored, but also the hazard levels of the gaseous emanations that could result (chlorine gas, hydrogen sulphide, etc.).

In this type of use, the liner is stronger and adapted to the effluent (pH, chlorine, density). Leak tightness will be achieved using a “liner” membrane specially formulated for U.V. protection, or by thermoplastic coating or by means of a sealant or elastomer seal between the bolted sheets.

The piping will be made from stainless steel.

These types of tank can also be used for methanisation or to store digestates from methanisation units. Whether you require anaerobic digesters, post-digesters, hydrolysis tanks or sludge silos, we can offer you the solutions best adapted to your needs using the appropriate steel and leak tightness techniques.

They can be equipped with immersed or lateral stirrers, immersed pumps, biogas injection mixing systems, walkways and hydro-ejectors, which we are able to supply.

This equipment may be required for effluent homogenisation or pre-treatment prior to release to downstream wastewater treatment plants.

Our solutions are intended for local authorities for liquid waste methanisation or the storage of sludge from wastewater treatment plants, for example, as well as for the industrial sector to store and process food-processing, chemical or pharmaceutical effluents.

Depending on the topography of the site on which these bolted metal buffer pools are installed, FM TANK can design and provide specific access platforms.
