Installer

 

HydroFLOW USA.

 

Customer

 

Somersworth NH WWTP.

 

Application

 

Centrifuge.

 

Installed units

 

Two 160i HydroFLOW units on a 152-mm (6-in) pipe feeding the centrifuge.

 

Background 

 

In 2015 HydroFLOW USA approached facility managers with a proposal to evaluate a technology for the ability to reduce polymer use. 

 

Success factor

 

Reduce polymer use and produce drier cake and the centrate quality needs to remain mostly unchanged.

 

Results

 

  • During six testing sequences, the units reduced polymer use from an average of 12 kg (25.5 Ib) per 0.9 Mg (1 ton) to 9 kg (19.1 Ib) per 0.9 mg (1 ton) for a 25.1% reduction. 

 

  • This increased cake solids by up to 3% TS and kept centrate quality within testing limits of less than 1000 mg/L TSS.
