Kemira produces advanced chemicals for pulp and paper, water treatment, oil and gas and other industrial chemical applications. The chemicals are used in municipal and industrial water treatment processes to remove foreign particles and organic matter. The company had experienced issues with contamination entering its chemical production process. Raw materials often contained stones, wood and agglomerated material. The contaminants could cause damage to the interior of reactors, as well as agitators, downstream pumps, valves and pipework.

“We were experiencing significant issues with damage to our reactors and other equipment, due to contamination in some of our hydrate powders,” David Sparks, plant manager at Kemira Chemicals, said. “As well as the high costs of replacing or repairing the equipment, this also meant costly production downtime.”

The solution was to incorporate a Russell Compact Sieve® to remove contamination from the incoming powders. It was used to screen up to 48 tonnes of incoming aluminium hydrate per day and protect downstream equipment from foreign contamination.

“We are delighted with how the Russell Finex sieve has performed since it was installed,” Sparks said. “It has been invaluable in checking incoming materials, meaning we’ve experienced virtually no problems with contamination and damage to our equipment. The unit is used all day, every day and has exceeded our expectations regarding durability.”

Established in 1934, Russell Finex has more than 80 years of experience in providing high-quality chemical sieving and filtration equipment.
