Industrial water treatment facilities cover a multitude of activities as part of the purification process before water can be returned to rivers and municipal drainage systems. Sludge created from the water recovery process is often dried on site, discharged into dumpers and transported away for landfill. Screw conveyors are used to transfer the sludge to the dryers and storage silos. Where space is a premium containerised forced drying and compacting plant is introduced and placed on structures which automatic discharge into open top container bins placed below, these being removed when full and stacked locally awaiting collection by road or rail. This model represents the Containerised drying facility.
