Within the WBL Multidisciplinary Projects framework agreement, the CWD-RWB combination is currently working on the Sludge Dewatering WWTP Venlo project. CroonWolter en Dros is responsible for the E and PA, RWB for the WTB part and GMB is affiliated for the civil work.
Because the Thermal Pressure Hydrolysis at WWTP Venlo is being taken out of operation, a new sludge dewatering installation must be ready. This installation must process the sludge from the WWTP Venlo, Venray, Gennep and Meijel, a total of approximately 7,500 tons of DM on an annual basis.
The sludge from Venlo is pumped from the existing thickeners to the sludge storage via a dirt removal step. The same happens with the external sludge from the new external sludge storage modules. From the joint storage tank, the sludge is dewatered using decanters and transported to the dewatered sludge storage.
Various Verdygo® modules are used in the project, including new Verdygo sludge modules that were designed earlier in the framework agreement, such as:
– Sludge pumping step
– Dirt removal sludge line
– Sludge dewatering
– Polymer storage
– Polymer production and dosage
– (external) sludge storage
