Spiroflow has expanded and updated its range of powder handling systems, specially suited to the accurate discharging and metering of water and effluent treatment chemicals, to help companies comply with the Landfill Directive (EC). Products used for pH control such as hydrated lime, activated carbon and soda ash are delivered in various forms and Spiroflow has designed equipment to suit all applications by dosing chemicals from silos, bulk bags and sacks. Bulk bag dischargers can be fitted with massagers for poor flowing products such as hydrated lime. Eliminating dust and environmental contamination, these systems can handle and dose chemicals using either a loss-in-weight or volumetric batching method.

A wide range of integral conveyors may be used to achieve very accurate dosing with rates as low as1kg/hr. Providing an even and consistent material flow, the Spiroflow systems can eliminate bridging of material and consequent starvation of the conveyor leading to the slurry tank.
