Submersible sewage pumps at work during soil remediation

Last year PRORIL Pumps Europe had used GOVOX-U 322 Submersible Sewage Pumps for a soil remediation project in Belgium.  The advantage of this pump model is the vortex impeller. It can also pump coarse particles and long-fiber materials. Read more....

 An old area in Vilvoorde, Belgium has been a source of concern for the local residents for many years. The area, which was once a thriving manufacturing plant, has been abandoned for decades and has been gradually deteriorating over time. The area is contaminated with hazardous chemicals and pollutants, which have seeped into the ground and posed a risk to the environment and public health.

In recent years, the local government and environmental agencies have taken steps to address the issue and to clean up the area. Ground remediation, a process of cleaning up contaminated groundwater, has been identified as the best solution to the problem. The ground remediation project at the area in Vilvoorde is considered to be one of the most comprehensive and ambitious in the region.
The first step in the ground remediation process was to assess the extent of the contamination. This involved taking samples of groundwater to determine the type and concentration of pollutants present.

Based on the results of the assessment, a remediation plan was developed that aimed to remove as much of the contamination as possible while minimizing the risk to the environment and public health. The remediation process involved the excavation and removal of contaminated soil, followed by the treatment of the remaining groundwater.

This excavation project required digging a three-meter-deep trench. To ensure the stability of the excavation and prevent water from seeping in, the project team used PRORIL solids handling submersible sewage pump GOVOX-U 322 to remove groundwater from the bottom of the trench. The submersible pumps were connected to hoses and were placed at the bottom of a pit in the trench, where they continuously pumped out the contaminated groundwater.

The PRORIL 3 inch GOVOX-U 322 electric submersible sewage pump features a vortex impeller coupled with a wide pump casing. The rotation of the impeller produces a whirling, centrifugal action between the impeller and pump casing. The action enables large solids and fibrous matters to be pumped without obstruction, leading to less impeller wear and longer pump life.
