CDEnviro shows true grit in battle against blockages

The chronic effects of rag and grit in waste water treatment could be a thing of the past thanks to new developments from waste management company, CDEnviro.

By incorporating high frequency vibrating technology in its machinery – such as its S:MAX G – CDEnviro is helping wastewater treatment operators deal with problems associated with rag and grit, including excessive wear, lost production, bypass effects with solids build-up in downstream tanks, and the resulting cleanout costs. Acute effects include screen blinding, reduced throughput and pipe and pump blockages.

High frequency screening addresses a number of the core issues that are apparent within conventional screening solutions, such as surface tension, blinding and rag retention.

Thanks to CDEnviro’s bolt-on component, high frequency vibrations can be used to recover grit in a simultaneous process with the rag. The S:MAX G is a wet screening system applied wherever there is a requirement for efficient grit and rag removal as independent outputs.

Unlike many grit recovery systems and vortex chambers in use today which only achieve a grit recovery cut point around 400-500microns, the Hydrocyclones in CDEnviro’s machinery will accurately recover inert grit down to 50-70microns. Below this size the grit will remain suspended in the water and not cause any issues during processing.

Recovered grit can be finally dewatered on a separate section of the high frequency screen that is in place to screen rag, therefore the S:MAX G from CDEnviro can recover both rag and grit in a simultaneous, in-line process.
