Next Generation Feroxsm Injection System
 ARS
and Precision took delivery of the first of
two large scale material mixing plants last
fall (shown to the right). The systems are
designed to mix and inject a wide range of
reactive materials and chemical reagents.
These custom designed units are capable of
handling 5 tons of material per day and are
able to inject slurries at rates up to 70
gpm and pressures up to 500 psig. The new
unit was immediately put into service at a
full-scale Feroxsm project being implemented
on the west coast. The fully automated plant
consists of a batch hopper, material screw
feeder, colloidal mixer and injection pump.
During operation, precise injection dosage
or water-to-reactive material ratio is automatically
achieved by the system once the parameters
are input into the on-board computer by the
operator. Digital load centers continually
monitor the mass throughput of the system
and record it to a data logger. This integrated
system insures good data quality control is
maintained during the mixing and injection
process. In addition,
the bulk bag (2,200 lb) loading system, eliminates
the need for manual handling of any injection
materials.
