producers to be more productive have been introduced by Solenis. MicroSol combines the patented
A
PerForm SP7242 structured polymer with structured PerForm MP9031 colloidal silica to maximise retention and drainage without sacrificing formation in the manufacturing process. As a result, papermakers are said to be able enjoy a wider operating window that increases flexibility, improves machine efficiency and reduces operating costs. “MicroSol builds on Solenis’
vast experience with retention and drainage aids,” said James Woodward, marketing manager, printing and writing, North America. “We significantly

dimensional structures that interact readily with cationic sites on fibres, fines and fillers in the forming paper. This structure allows the molecules to grab hold of ash and distribute it evenly to increase paper strength, retention and formation. The PerForm MP colloidal silica
changed the retention and drainage landscape when we introduced our patented PerForm SP structured polymer in the early 2000s. Early generations of PerForm SP set the bar for first- pass ash retention. Now, with the introduction of PerForm SP7242 and our MicroSol package, Solenis
is raising the bar even higher. To complement this technology, we’ve also created PerForm MP9031, a colloidal silica that adds to the retention initiated by PerForm SP yet promotes excellent drainage.” PerForm SP molecules are said to be highly anionic, three-
offers a similar microstructure developed with attention to its size, surface area, structure, surface modification and solids content to ensure optimum performance in today’s paper machine processes. Used together, PerForm SP and PerForm MP offer a dynamic breakthrough combination that gives papermakers the ability to maximize retention and drainage without sacrificing formation.

Accurate high dry solids measurement for pulp and paper lines
A new technique for measuring high solids in fluids for use in pulp and paper production and industrial waste water treatment has been launched by Valmet. Originally designed for municipal waste water plants, Valmet HS is based on microwave technology and features a patented sensor structure. It extracts a continuous sample flow from a downfall or drop leg section in the process and returns it after the solids content has been measured. Valmet HS measures more than 30 per cent solids or 1-70 per

number of benefits, such as making it possible to optimise total solids levels and follow up, in real time, the performance of dewatering or drying processes. Already in use after a high-
cent moisture. “We see high potential for this solution especially in the pulp and paper industry where an accurate high solids measurement provides many benefits, such
as improved high consistency control, cost savings and higher quality,” says Jarmo Havana, product manager for automation at Valmet. Valmet HS is said to bring a
consistency roll press, Valmet HS provides accurate pulp consistency control to refining and consequently more stable- quality pulp to the paper machine. Benefits include lower press energy consumption, reduced fibre crushing and the prevention of too high consistency causing damage to process equipment.
