High-frequency ultrasound for powerful regeneration of groundwater wells
During operation, biofilms and other biological contamination form in the pore spaces of the filter gravel pack in well systems. This leads to a continuous reduction in performance and can cause the well to fail in the long term. Conventional methods reach their limits here, as the affected areas can only be reached mechanically to a limited extent.
This is precisely where our technology comes in:
By using high-energy ultrasound, biofilms, pathogenic substances and microbiological contamination are reduced in a targeted manner. The ultrasonic waves penetrate deep into the pore spaces and unfold their effect there. Constricted pore structures are exposed and the hydraulic performance of the well is sustainably improved.
Our solution: high-energy ultrasound
The use of high-frequency ultrasonic technology creates intensive cavitation that penetrates the inner structures of the filter gravel pack.These physical processes enable particularly deep and uniform treatment of biological contamination – even in areas that are difficult to access.
The result is sustainable stabilization of well performance and effective control of biofilms and microbiological processes.
Chemical-free. Precise. Sustainable.
In contrast to many conventional methods, our technology works completely without chemical additives.The treatment is carried out exclusively using precisely controlled physical processes based on high-frequency sound waves.
Biofilms, pathogenic substances and microbiological contamination are effectively reduced without impairing the well structure or polluting the groundwater.
Process of efficient well regeneration with ultrasound:
Preparation
- Removal of pump and riser pipes: The pump and riser pipes are removed from the well to allow access to the filter section.
- Inspection with camera: The condition of the well and the filter section is comprehensively inspected with the help of a camera. This allows any damage or blockages to be detected at an early stage and rectified in a targeted manner.
- Performance test: Before the actual cleaning, a performance test is carried out to determine the flow rate and water quality of the well. These values serve as a reference for assessing the success of the regeneration.
Cleaning
- Mechanical pre-cleaning: Coarse dirt and deposits are first removed mechanically, for example using a brush or a flushing pipe.
- Optional performance test: After mechanical pre-cleaning, a further performance test can be carried out to quantify the effect of pre-cleaning.
- Ultrasonic application: The heart of well regeneration is the ultrasonic application. A high-frequency ultrasonic probe is guided along the filter section from top to bottom. The sound waves effectively remove deposits and biofilms from the filter gravel surfaces and pore walls.
- Dirt removal: The dirt loosened by the ultrasonic treatment is removed immediately after sonication using an underwater pump. The pump is mounted directly above the ultrasonic probe.
Control
- Optional camera inspection: A new camera inspection can be carried out to document the success of the cleaning and to detect any residual soiling.
- Performance test: Once regeneration is complete, a final performance test is carried out to determine the new flow rate and water quality of the well and to document the success of the measure.
- Reinstallation of pump and riser pipe: At the end of the regeneration, the pump and riser pipes are reinstalled in the well.
