Smurfit Kappa Paper Recycling Plant Birmingham

Heat exchanger protection at Smurfit Kappa Paper Recycling Plant, a paper mill for 130 years is assisted by BOLLFILTER products. The mill produces 200,000 tonnes of liner and fluting paper from recycled card and paper sourced from Local Authority and trade waste.

The recycling process produces three m3 of water effluent per tonne of paper. This waste water is treated in a new, state of the art water treatment plant, which removes COD (Chemical Oxygen Demand) by means of anaerobic digestion. This biological process must be carried out at a constant temperature of 37 degrees, 10 degrees less than the normal temperature of the recycled waste water. As a result, a heat exchanger system is necessary to remove the excess heat, which is then used in other parts of the plant.

The heat exchanger, which is a wide gap plate system, must be protected from risk of damage from particulates in the raw water. Smurfit Kappa uses two filtration processes to achieve this: firstly a DAF Dissolved Air Flotation System, which uses flocculants to remove plastics and larger contaminants; and secondly an automatic, Self-Cleaning BOLLFILTER System, which filters down to 1mm.

Smurfit Kappa’s Water Treatment Plant has proved a great success. Austin Jakeman, Project Manager, explains: “Since installing the anaerobic system, we have improved the quality of our waste water and dramatically reduced our water discharge costs.” As the heat exchangers need to constantly maintain the correct water temperature, it is vital that they are protected from damage and risk of down-time.The BOLLFILTER Automatic, which can operate continually without the need for regular cleaning or maintenance, forms the final heat exchanger protection barrier against particulates entering the system.
