We revolutionize digester emptying: faster, more efficient, no stops

Digester emptying Digester emptying is a key operation in the maintenance of waste water treatment plants. However, traditional methods involve slow, costly and often problematic processes. At Protech Continental we have developed a technical solution that transforms this process: the combined system BIOCRUSH & BIOPRESS.

Limitations of the traditional system

The conventional procedure for emptying digesters is usually done with tank trucks that inject water under pressure to remove waste and use a suction system to extract it. Although it is a widespread practice it has several drawbacks: it requires costly intervention, involves long downtimes and generates waste which must be managed separately.

These limitations directly affect the overall performance of the plant and make efficient maintenance planning difficult.



BIOCRUSH & BIOPRESS: A new approach

In contrast to this traditional model, at Protech Continental we propose a more effective, safe and fast solution. The BIOCRUSH & BIOPRESS system allows continuous digester emptying without having to stop the installation.

BIOCRUSH acts by decompacting and crushing the waste accumulated inside the digester, while BIOPRESS pumps the material directly to the plant head, specifically to the coarse well. The whole works at a constant rate of between 50 and 60 m 3/h, which makes it possible to considerably reduce intervention times and avoid the use of external trucks.

This system not only streamlines the process, but also optimizes resources and minimizes operational impact by reintegrating waste into the WWTP’s own treatment system.



Technical efficiency, minimum disruption

With this technology, digester emptying is no longer a complicated process. The time required is reduced, dead times are eliminated and waste movements are avoided. In addition, as a mobile solution, it can be deployed on different sites without the need to modify infrastructures.

Pump rental for maintenance shutdowns: key sectors and temporary solutions

Pump rental is a temporary solution designed to maintain operational continuity when an industrial facility undergoes a planned maintenance shutdown, experiences a breakdown or requires a bypass during maintenance work. In practice, it provides a temporary replacement for a main pump, supports a critical transfer operation or manages dewatering without interrupting the process.

How to size a stirrer for a biogas digester based on diameter, height and substrate type

Sizing a stirrer for a biogas digester involves more than considering volume alone. Diameter determines horizontal coverage, height defines vertical reach, and substrate type determines the risk of sedimentation, crust formation or loss of homogeneity. The practical consequence is clear: poor agitation can compromise process stability, increase stirrer energy consumption and raise total operating costs.
