Carbon Filtration Slaves
150, 300 & 330 gallon modular units to
collect precious metals from water    
*pre cleaned water recommended
Carbon Filtration Slave Pallet Paks
These units receive water supply into the top processing up to 100 gallons per minute. As water
passes downward, it is stripped of metals and discharged out of a 2” valve at the bottom, clean and
ready for return to processing, alternative uses or the environment.

Tanks are filled with specialty
Coconut carbon pellets in loose form or bagged for easier handling
through a 5” top opening, once placed at it’s final run location.  *Units can weigh up to one ton when
filled with carbon.(sold separately)

These system can handle moderate pressures from pumps as well, up to 20 PSI, but scavenge the
metals best at gravity-only speeds.  Higher pressures and water speeds are for very low
concentrations of metals in large volumes of water.

Typical recommended applications are flooded mines, tailings ponds and pre-cleaned surface waters.
These also double as water purifiers and remediation systems.

The bed depth and shape has been designed for complete removal of metals and other substances for
metals recovery, water purification and  water preparation for leaching plants.

No maintenance is required under normal circumstances for complete passive recovery, and will last
for months at a time, or until you wish to remove contents for processing.  Entire units can be shipped
intact to refiners or processors.  Owing to the massive amount of metals this unit can trap, unit sits on
a built-in skid to allow forklift mobility.  Loaded units can weigh 2,000 lbs. or more.

These can be ganged together by common 2” plastic pipe or hoses to handle unlimited volumes of
water, yet small enough individually to handle with ordinary equipment. Multiple arrays can be run 24
hrs per day with minor overview and monitored by remote with automatic/PC controls.

We recommend placement on a level concrete slab for best performance.

Controls on water flows in and out of these units is advised

As we are filling these with loose-fill carbon pellets, these have two characteristics:

1. Carbon tends to cohere…that is, stick together, as it begins to adsorb the metals you seek.

2. Carbon will help prevent the bulging associated with distortions that additional weight will provide
this system.

Tank walls are translucent enough to help you determine what is going on inside, and equipped with
gallon indicators.  All tanks have a 5” spin-off top for filling, and a separate 2” fitting for connecting
the plumbing into the top, for water.

These units have skids built in to enable fork-lift moving them…a necessity, considering how heavy they
are once loaded, and the additional weight you will gain after loading with metals.

These units require your plumbing fittings, labor and separate Carbon purchases.
* You install the bottom discharge pipe fitting and valve on all units.

Rectangle Paks have metal frames and plastic bases.
Tanks are manufactured from medium-density
polyethylene. Pallet Paks come with UV inhibitors and
designed for containment of liquids of up to 1.7 specific
gravity.  Tank walls are tranlucent for level viewing and
equipped with gallon indicators. All tanks have a 5" lid
and a 2" fitting on top.
