Optimal drainage and retention are important parameters in papermaking. The right amount of chemicals added in the right position in the stock preparation increases both productivity and product quality. As the DDA gives drainage values comparable to real drainage situations on modern paper machines, it is in use by papermakers, chemical manufacturers and R&D companies worldwide.
“DDA 5 has a compact design and is equipped with new features like the turbidity sensor which automatically gives the retention value,” says Öjvind Sundvall, MD, PulpEye. “The drainage rate can be presented for chosen time intervals during the analysis. The chemical dosage is done automatically. As the equipment is automatically cleaned after each analysis, more analyses can be done per hour in comparison to previous models. All data input and presentation of results are done with a new user friendly interface.”
DDA 5 has a more compact design than its predecessors and consists of only one unit.
