A MAJOR investment in Immingham has brought a first for the company behind it, after a tender was won to reactivate spent carbon filters for drinking water.
CPL Industries has successfully handled its first batch for a British utility, having worked solely on industrial applications previously.
Now, having invested in a dedicated facility to keep the process completely separate to that operated for the past five years, a first tender has been won to deliver.
It involves a thermal reactivation process, passing the spent material through a high temperature kiln to restore filtration capacity.
CPL’s divisional director Steve Bell, pictured left, said: “After more than five years of reactivation operations for industrial customers, we are delighted to make this first step into drinking water carbon regeneration, following the investment made by the company in our facilities and also the winning of our first reactivation tender.
“We were convinced that there was room in the market for additional reactivation capacity, and our facility at Immingham is second to none in terms of its capability and efficiency. We look forward to working closely with the water utility industry and taking on more work in this sector.”
Activated carbons are used in a wide range of gas and liquid phase filtration applications, such as air treatment, water purification, food and beverage decolourisation and numerous other environmental protection applications.
Spent activated carbons from the various purification applications are generally categorised into two broad types, which dictates how they are subsequently handled and reprocessed. Spent carbons from industrial applications such as air and gas filtration, waste water and remediation projects are referred to as ‘amber list’ materials. Carbons that have been used in drinking water or food grade applications are referred to as ‘green list’ materials.
Following a major investment by the parent company, CPL Industries, The Food & Potable Grade Reactivation unit is a state-of-art facility incorporating a number of innovation technologies to ensure customers’ carbons are reactivated in an efficient and cost-effective manner. As well as the separate build for the green reactivation, the company’s existing ‘amber’ reactivation plant has also had its capacity increased as part of the ongoing investment programme.
Mr Bell added: “The benefits of reactivating spent carbon, rather than disposing of it and replacing with virgin material, are considerable, both in terms of cost and environmental impact and CPL believes strongly in the recycling of spent carbons wherever possible.”
