07-7245: Quadplex Polymer Metering System

Marathon - Ghislain Hachey, EIT — 2009-10-12T16:45:54-07:00

Marathon has completed the supply and commissioning of the following design/build metering system:

Fouplex custom designed metering system featuring Grundfos DME series Metering Pumps providing virtually 100% continuous polymer injection with 800:1 metering rate turndown.

Sodium Hypochlorite Metering - Marathon/Thunder VS Others

Marathon - Ghislain Hachey, EIT — 2009-10-06T05:43:15-07:00

Marathon has an alternative to sodium hypochlorite metering eliminating the need for dilution recipe and daily/weekly maintenance.

Solutions include pre-engineed Duplex metering packages locally designed, built and supported in Moncton, NB featuring Grundfos/Alldos self degassing metering pump technology DDI-P3 series.

The following shows the Marathon/Thunder pre-engineered system equivalent to another product on the market. The system shown on the left replaces ALL of the cumbersome system on the right with added features and improved process operation while being operator friendly.

WHICH OF THE ABOVE SYSTEMS WOULD YOU RATHER MAINTAIN?

Many municipalities have reduced their daily maintenance on other equipment (shown on the right) to virtually no maintenance in (2) years with a Marathon/Thunder Duplex Sodium Hypochlorite Metering Package (shown on the left).

02-3204: WWTP WAS Pump Vertiflo Upgrade

Marathon - Eric Fisher, P.Eng. — 2009-10-05T03:58:54-07:00

Faced with increased maintenance cost and difficulty obtaining replacement parts of aging Chicago WAS pumps equipped with mechanical variable speed drives, this WWTP decided to upgrade to more compact Vertiflo 1600 Series 100% recessed impeller pumps with single mechanical seals requiring no flush water and variable frequency drives.
Pumping up to 5% WAS, the first Vertiflo unit was installed in 2003. Since then a total of four (4) units have been upgraded.
To date the only service parts required has installation has been one mechanical seal after the pump had been inadvertently operated dry for a period of time.
