CDEnviro's Innovation Leads To Awards Shortlisting

Waste solutions specialist finalist in Water Industry Achievement Awards 2017

CDEnviro’s S:MAX G – a sludge screening system used in the pre-treatment stage in waste water treatment– is a finalist for the category of Most Innovative New Technology in the Water Industry Achievement Awards’.

An industry first – the S:MAX G uses high-frequency vibrations to recover grit and rag from the process line.

The S:MAX G, launched in 2016, is a configuration of the S:MAX which screens rag. The S:MAX G includes new technologies which can separate rag and grit as independent outputs. Grit is removed in the pre-treatment stage, reducing wear and maintaining capacity in tanks further down the treatment line.

Its abilities have been proved at Northumbrian Water, which was experiencing efficiency loss due to grit in its digesters. Each one needed to be cleaned out when capacity reached 250 tonnes; typically every seven years.

Cleaning costs in the wastewater treatment industry are substantial with 50% loss of production for two weeks, re-processing costs, supplementary transportation, additional man hours, 0% production for a further two weeks, and the costs of a cleaning contractor and final disposal. A 1,000m3 digester clean out could cost up to £100,000.

In August 2016 Northumbrian water trialled the S:MAX G at a site with three digesters. Extrapolated data indicates that over a seven-year period, 525 tonnes could be processed effectively, and therefore would not enter the digester tanks. This would result in the digester tanks only having to be cleaned out every 23 years.

Peter Hayes, Business Development Executive at CDEnviro, said, “We work closely with our customers to identify innovative ways to solve problems, so we’re delighted that our wastewater solution has been shortlisted in this award. In the wastewater treatment industry, the problems associated with rag and grit have troubled operators for years.”

“These problems have almost become tolerated in treatment works today with operators becoming comfortable with a duty/standby approach being adopted. This however is not addressing the core issue; rag and grit need to be removed from the flow process as quickly as possible. With our innovative screening system we, and our customers, are tackling this issue head-on.”

The Award winners will be announced on the night of Tuesday 23 May at a ceremony at The Vox, Birmingham. www.cdenviro.com
