APPLICATION DESCRIPTION This site is one of the critical water supply sites in . It is in a very exposed location beside Lough Mourne, on the road up from Ballybofey towards the bleak but scenic . The water is sourced from this Lough. It is very ‘hard’, as the underlying rock is limestone. The soda ash is added as a pre- treatment stage, removing calcium to soften the water.

SKE Solutions have fully designed, built and installed a bespoke system for this application. There is a large outdoors silo which incorporates an internal mechanical ‘arch breaker’ at the base. The arch breaker very effectively delivers powder and prevents any product blockages in the silo cone. Intrinsic metering and transfer conveyors deliver the ash to the weigh hoppers above the mixing tanks, which are installed indoors. These mixing systems were designed to fit the existing building and a bespoke system ensures the optimum solution for this application.
