Hydrodemolition creates used water known as slurry, as well as solid debris made from concrete and aggregate, and containing the slurry and debris is often considered one of the more challenging aspects of hydrodemolition.
However, planning ahead and using the right equipment means the slurry and debris can be easily managed and contained, allowing for an efficient and effective cleanup process.
While one operator controls the robot on a project, another operator will use the vac truck to remove debris and slurry from the area. This process not only collects the debris and the slurry, but it begins the process of filtering the slurry of suspended solids.
The collected slurry is then pumped to our state of the at water filtration system. This portable system uses flocculant, coagulant, CO2, and a series of baffles to remove the suspended solids and balance the ph. Our system is automated and provides readings of the water quality after the filtration process. This process cleans the water to such an extent that it can be safely disposed of into city sanitation systems, or it can be reused for the hydrodemolition process.
To help with the water containment and filtration, our operators will set up baffles, weirs, or shielding to help contain the water to certain areas and to encourage pooling, which not only begins the filtration process due to gravity, but makes it easier to pump the water to the filtration system. Using shielding helps protect surrounding areas from the slurry and debris in addition to containing it to a specific area.
