Spent carbon reactivated from drinking water facility
Wigan-based company CPL Activated Carbons has successfully reactivated its first batch of ‘green list' spent carbon from a drinking water treatment facility.
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.
When carbons are ‘spent’ and no longer achieving the required level of filtration, they need to be replaced. In most cases, spent carbons can be regenerated by a process called thermal reactivation, which involves passing the spent media through a high temperature kiln to restore its filtration capability.
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, wastewater 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.
CPL’s carbon regeneration facility is located at the group’s manufacturing site in Immingham, North-East Lincolnshire, where it has been successfully reactivating ‘amber list’ spent carbon filtration media from industrial applications since 2013.
Following a major investment by parent company CPL Industries, the company also now has the capability to reactivate ‘green list’ spent carbons and recently won its first tender with a major UK water utility located in the south of the United Kingdom.
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.
The ‘green’ reactivation facility is in a completely separate building to the company’s existing ‘amber’ reactivation plant, which has also had its capacity increased as part of the ongoing investment programme.
CPL divisional director Steve Bell 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.”
CPL Activated Carbons supplies activated carbons, mobile carbon filtration systems and spent carbon reactivation services.
