Metalfab Feeders & Bin Activators for Water & Wastewater Systems

Wastewater Screw FeederMetalfab Water and Wastewater Treatment Systems combine a rugged, durable Bin Activator with a secondary baffle that vibrates at a separate amplitude to guarantee continuous flow of product, and a MetaTech(TM) Feeder (with only 2 or 3 moving parts for simple maintenance) and unique agitator/conditioner screw that completely fills the product feed screw for accuracies of +1 to 11⁄2%.

Bin Activators are available in 2′-16′ dia. and MetaTech Feeders are available in 1″-6″ screw sizes in a choice of carbon steel, 304 or 316ss. Systems inclusive of all ancillary equipment and controls can be configured to meet any water/wastewater treatment requirement.

In the application pictured, powdered limestone with a bulk density of 85 lbs./cu. ft. is being discharged from a silo fitted with a Metalfab 5′ Bin Activator that is connected by a flexible sleeve to the 5 cu. ft. hopper of a MetaTech MT-3 with Level Probes. The MetaTech feeds the powdered limestone at a rate of 30 cu. ft. per hour into a slurry tank. The level probes control the on/off operation of the Bin Activator. The resulting slurry is then used to treat and adjust the pH of the downstream water.

Metalfab has successfully handled lime, hydrated lime and other products used in water treatment for decades.
