The two systems, supplied by Technotrans' UK distributor WRH Marketing, will be attached to an existing delta.sd dampening system, which is already in place on Trinity's two five-tower KBA Commander web press.

David Beagan, chief engineer at the plant, said: "Filtration is vital to us from an environmental perspective. The solids don’t go down the drain and the liquid from the dampening solution is recycled to reduce our fount bill.

"It is green and cost-saving. It requires very little maintenance because the filters clean themselves so all we do is occasionally decant the sludge tanks."
