The high efficiency of the HUBER STRAINPRESS® units becomes especially evident when comparing them to the four screens that are installed in the STP inlet and have a bar spacing of 6 mm and width of 4 m each:
The screens separate an annual screenings volume of 125 tons dry substance. A downstream screenings press compacts the screenings to a dewatering degree of 25%.
In comparison, the downstream STRAINPRESS® units separate 600 tons dry substance a year, which is five times the volume the screens are able to remove. The integrated dewatering mechanism constantly achieves dewatering degrees of 40% and thus can produce a combustible product.
Since the STRAINPRESS® is a completely odour-encased system, neither sludge nor screenings cause a corrosive or explosive atmosphere inside the building. The machines can nevertheless be completely opened very easily for inspection or maintenance.
Since the installation of the HUBER sludge screening systems at the beginning of 2011 maintenance costs and shutdowns have been reduced significantly on STP Amsterdam-West.
The operating reliability of HUBER STRAINPRESS® systems can be witnessed not only on the reference sites Amsterdam and Den Haag in the Netherlands but also on many other sites all over the world, such as Berlin, Barcelona, San Diego, Seoul, Marrakesh, etc.
