MuckMix is a patented reagent system
designed for large volumes of low-density oily wastes. MuckMix initiates a unique series
of chemical reactions, which stabilize and solidify oily wastes into an impermeable and
leach resistant product with typical permeabilities less than 1.0 x 10-6
|MuckMixs unique blend of reagents
converts oily waste sediment, sludge, and soil to useful soil-like material. The soil-like
material has the properties of normal soils, can be graded and compacted and is suitable
for on-site closures or reuse as construction material. Typically, the enhanced unconfined
compressive strength of the treated waste material is greater than two tons per square
foot (2 tons per sq. ft.).
MuckMixs reagents are easy to apply using traditional in-situ
methodology and equipment such as backhoes, rototillers, and long stick trackhoes. Depths
of oily lagoons to 22 feet have been stabilized with MuckMix.
Typical refinery sludge lagoon being prepared for MuckMix
A major refinery undertook the closure of a series of
impoundments that contained accumulated oily wastes from past operations. The six
impoundments at the site covered over 30 acres, and contained a mixture of petroleum waste
sediments, included listed wastes, oily residues and standing water. Five hundred thousand
cubic yards (500,000 cu yds) of sludge and over two hundred thousand cubic yards (200,000
cu yds) of stockpiled soil were included in the closure.

|The sludges were problematic and highly
variable due to differing amounts of contamination and physical characteristics:
- Oil and grease up to 20% (by EPA 9071);
- Solids ranging from 15% to 67% on a wet weight basis;
- TCLP benzene from less than 0.01 mg/l to 2.3 mg/l;
- Densities ranging from 65 to 88 pcf;
- Wastes ranged from thin, free-flowing liquids to soil-like
The project goal was to efficiently and cost effectively
stabilize the waste to achieve the following limits:
- Effect a greater than 3.0 tons per square foot penetration
- Assure a permeability equal to or less than 1.0 x 10-6 cm/sec;
- Meet and exceed TCLP characteristic limits.
|A series of MuckMix
formulations were developed to handle the waste variability. These were bench scale tested
and verified through a full-scale field demonstration.
production runs, select fill was added to the wetter sludge in advance of the
solidification activities. The consistency of the pre-treated materials ranged from
sludge-like to soil-like. MuckMix was then added at the rate of 35 pneumatic truckloads
per workday equal to about 3,500 cubic yards of production per day. The overwhelming
majority of the solidification took place in-situ using trackhoe mixing, at depths up to

|MuckMix not only met and often surpassed
the project goals. MuckMix was also nearly 40% cheaper than the Portland cement mix.
