French environmental services firm, SUEZ, has achieved end-of-waste/waste-derived material accreditation on its final products at its commercial depot and transfer station in Willenhall, West Midlands with the use of new high frequency wet processing equipment from CDEnviro.
According to CDEnviro, since it installed its CO:FLO cleansing system SUEZ has significantly reduced downtime due to plant wear and blockages when processing road sweepings and other waste material.
The County Tyrone, Northern Ireland based manufacturer of waste reduction and recycling equipment the solid waste management and wastewater industries, explained that Road sweepings and construction and demolition materials can be difficult to process. It said that this is particularly true in water treatment systems, where the process is complicated by the issue of the physical and chemical cleanliness of the waste material.
The CO:FLO is a liquid/solid separation system, resulting in optimal water clarification and solids ssettlement.
Sean Dobbs, product development engineer at CDEnviro explained that the company worked with world renowned university, Trinity College Dublin, to develop this solution to improve our water treatment system and in turn increase the quality of the final products.
“The research project led us to develop the CO:FLO, which results in 5-10 times cleaner water than that of a traditional high rate clarification system,” he said. “The CO:FLO marks a significant step forward in technology, emphasised by the multiple patents pending around the design.”
The company said that the system is is designed to enhance health and safety for onsite operators. All chemical addition points and chemical storage are enclosed within the unit, therefore minimising contact and greatly reducing the risks associated with handling chemicals.
Additionally, an operator access roller door is interlocked with the main door ensuring operator safety when changing intermediate bulk container (IBCs).
CDEnvio said that the system allows operators can process materials more quickly thanks to the modular design which allows rapid site erection, speeding up the commissioning process.
According to Martin Bladon, SUEZ site manager at Willenhall, since the CO:FLO was installed on the road sweepings processing plant has operated without issue and virtually zero maintenance.
“We have noticed a significant increase in the level of contamination in our centrifuge cake which is a testament to the effectiveness of the CO:FLO,” he continued. “There is also the added bonus of being able to increase plant throughput due to this new level of performance.”
As a result, Bladon said that sand and aggregate products are now within the aggregate quality protocol limits and can be de-classified as waste and certified for reuse.
“This is a significant milestone not just for SUEZ but also for the road sweeping process industry as a whole and we are proud to be leading the way,” he concluded. We continue to work with CDEnviro in our joint goal of achieving sustainable revenue generating outlets for all of the recycled materials produced by our plant.”
