Filtration and solids-liquid separation

Filtration is a vital unit operation throughout the chemical industry and Process Plant Technology has particular strength in selecting appropriate equipment and system development. This is a key unit operation for removing crystals or sludges from process concentrates.

Where large crystals are produced centrifuges are normally used. Our experience is with two stage pusher, worm screen, decanter and basket type peeler units. Centrifuges by their nature are manufactured from metallic parts to withstand the corrosive nature of the processes encountered. Often this requires selecting expensive materials to resist corrosion in arduous applications. We have supplied centrifuges manufactured in 316L, 904L, Monel and SAF2205 and many other
corrosion resisting steels.

The company has no exclusive filter agencies, preferring to utilise our filtration experience to select the most effective unit from the many vendors with whom we maintain regular contact. This range includes pressure leaf, disc and drum filters, belt filters, filter presses, membrane presses, screw presses, roll presses, sewage dewatering and belt presses.
