The Thames Water Trident Alliance chose Saxlund International to supply this prestigious and unusual limed sludge cake handling system at their Farnham site. Because of the maximum building height on the site and since the silo had to store 800m3 of limed cake material, it was necessary to supply a silo with an 11 meter diameter.

To achieve this, Saxlund chose their patented two-element Sliding Frame discharge machine - the largest ever constructed for such an application. It was not possible for the collection truck to drive beneath the silo as would normally be the case. A large chain conveyor was therefore supplied to transfer the limed cake from the twin-screw arrangement beneath the silo’s flat floor and up to the truck loading position within a gantry. The control system was also within the scope of works.
