Bolted Aeration Tanks

Wastewater aeration is a critical process carried out in various facilities. Concrete reactors are commonly found in municipalities and large industrial sites, while lagoons are suitable for expansive areas. However, when space is limited, bolted aeration tanks emerge as a practical solution.

Bolted aeration tanks offer distinct advantages. Their modular design ensures easy scalability, allowing facilities to adapt to changing needs. Rapid installation minimizes downtime, facilitating the seamless integration of wastewater treatment systems. From a cost perspective, bolted tanks excel due to their straightforward installation, requiring minimal infrastructure and civil engineering works compared to concrete reactors and lagoons (such as excavation, concrete laying, and lining). Moreover, these tanks demonstrate a commitment to sustainability by utilizing recyclable materials, enabling them to accommodate large wastewater quantities within a small geographical footprint.

Mapal provides a comprehensive aeration solution for bolted tanks in biological wastewater treatment. Floating Fine Bubble aeration units from Mapal are well-suited for bolted tanks as they do not make direct contact with the lining. These units remain in place, ensuring complete tank coverage and the ability to function above malfunctioning diffusers. Mapal’s Retrievable Fine Bubble aeration units feature padded legs to prevent damage to the tank lining.

The installation process for Mapal’s aeration units is efficient and straightforward. Using a crane, the units are placed in a full tank without the need for draining, offering significant logistical and time-saving advantages. Importantly, this method eliminates the need for personnel to be in the wastewater, providing a substantial health and safety benefit.
