The pump churns grease & scum to prevent smaller pumps from clogging
At the Benton Utilities Wastewater Treatment Plant near Little Rock, Ark., a new Landia EradiGator chopper pump is ensuring grease and scum are continuously churned up to prevent other smaller pumps in the process from blocking.
The recirculating chopper pump was supplied by Landia with a custom-built bracket to fit into the bottom of a square tapered scum pit at Benton, where the scum pit receives skimmed-off wastewater from the plant’s clarifiers.
“We’re really using the Landia Chopper Pump more as a mixer so that a layer of scum can’t build up and block the existing smaller pumps we have on our rail system,” said Jonathan Buff, manager of Benton Utilities Wastewater Treatment Plant. “Either way, it’s very effective”.
“Previously, we did experience problems with blocked pumps, especially because we are working with just a 3-inch line,” Buff said. “But the Landia Chopper Pump keeps everything churned up and on the move, with no problems for our existing units, which can now send the mixed scum to our digesters with no breakdowns or downtime.”
Landia’s EradiGator chopper pumps are used in lift stations and scum pits for mixing and macerating debris and grease, in order to prevent clogging of pumps and piping.
